DPU vs. CPU vs. GPU: Understanding their Key Differences

In traditional computing architectures, Central Processing Units (CPUs) and Graphics Processing Units (GPUs) play an important role, but with the increasing volume of data and the emergence of diversified data processing needs, these traditional units are gradually showing some bottlenecks and limitations. The introduction of DPUs makes up for these shortcomings and provides a more efficient, flexible, and customisable data processing solution. In this article, we will explore the differences and connections between DPUs, CPUs and GPUs.

What is a CPU?

The central processing unit (CPU) is the core of a computer system, responsible for executing instructions in the program and controlling the operation of other hardware. CPU adopts a single, more complex core structure. CPU is like the ‘brain’ of the computer. It handles all the basic tasks of computer work, such as running programmes, managing files and performing basic calculations.

Think of it as a human brain, making sure that all your faculties and behaviours are in order. Different types of CPUs may have different instruction set architectures (e.g. x86, ARM, etc.) for different application scenarios, such as personal computers, servers, embedded systems, and so on.

What does a CPU actually do?

At its core, a CPU takes instructions from a programme or application and performs calculations. There are three key stages in this process: fetch, decode and execute. In the fetch phase, the CPU reads instructions from memory. In the decode phase, the instruction is decoded to determine the operation to be performed. The execution phase performs the actual computation or operation according to the decoding result. The write back stage writes the result of the execution back to memory or registers.

What is a GPU?

Originally designed to handle graphics and image-related computations, Graphics Processing Units (GPUs) have been gradually expanding their applications as fields such as scientific computing and deep learning have evolved.

Unlike the serial processing of traditional CPUs, GPUs have thousands of highly parallel cores that are able to break down complex computational tasks into countless smaller tasks that are processed simultaneously. This highly parallel architecture allows GPUs to excel in scenarios that require large amounts of computation for tasks such as graphics rendering, machine learning (ML), video editing, gaming applications, and computer vision.

GPU Application Scenarios

Professional Visualisation

GPUs not only play a role in entertainment, but also excel in professional applications. For example, GPUs provide the computational power to process and render complex graphics in CAD drafting, video editing, product demonstration and interaction, medical imaging, and seismic imaging. These applications often require the processing of large amounts of data and complex image processing tasks, and the parallel processing power of GPUs makes them ideal for these tasks.

Machine Learning

Training complex machine learning models often requires a significant amount of computational power, and GPUs, with their parallel processing architecture, can significantly accelerate this process. For those training models on local hardware, this can take days or even weeks, whereas with cloud-based GPU resources, model training can be completed in a matter of hours.

Simulation

GPUs are used in a wide range of high-end simulations. Simulations in areas such as molecular dynamics, weather forecasting, and astrophysics all use GPUs to perform complex calculations, and GPUs are able to rapidly process and simulate large-scale physical systems. Additionally, in the design of automobiles and large vehicles, applications involving complex simulations such as fluid dynamics also rely on the powerful computing capabilities of GPUs for accurate modelling and simulation, helping engineers to optimise designs and reduce the need for physical testing.

What is a DPU?

The DPU, or Data Processing Unit, is a major key component in the future of computing. It is a hardware unit specifically designed to process data, with a greater focus on efficiently performing specific types of computing tasks. DPUs can share the work of the CPU in four ways: networking, storage, virtualisation and security.

Typically, DPUs are integrated into SmartNICs (Smart NICs) as a third computing unit in addition to CPUs and GPUs, which builds the heterogeneous computing architecture of the data centre.

Application Areas for DPUs

DPUs are an important part of the future of computing, and their applications cover a wide range of areas, from deep learning to edge computing and cryptographic security.

Deep Learning

Deep Learning is one of the important application areas of DPU. DPU, as a hardware unit specially designed for data processing, has excellent parallel computing capabilities and efficient data processing capabilities. DPU achieves fast training and inference of deep learning models through hardware accelerators, which greatly improves the efficiency of deep learning tasks. In fields such as natural language processing and computer vision, DPU achieves faster and more accurate text analysis, image recognition and other tasks by accelerating the training and inference process of models.

Edge Computing

Edge computing is another important application area for DPUs. As specialised data processing units, DPUs can perform complex computing tasks on edge devices to meet the needs of edge computing. In industrial automation, intelligent transportation, healthcare and other fields, DPUs can monitor and analyse real-time data, help users perform predictive maintenance, intelligent scheduling and other tasks, and improve the efficiency and reliability of the system.

Encryption and Security

With the increasing importance of data security and privacy protection, encryption and security have become important issues in the computing field. DPU can achieve efficient encryption and security processing to protect the security of user data. In the field of network security and intrusion detection, DPU can achieve real-time data monitoring and analysis to help users find and respond to network attacks and security threats promptly, to ensure the security and stability of the system.

The rapid growth of global arithmetic demand has driven the development of DPUs.NVIDIA, as a pioneer in the DPU field, has launched the BlueField series of DPUs and predicted that the DPU market will see explosive growth.FS, as one of NVIDIA’s partners, provides NVIDIA’s series of smart NICs, covering the ConnectX®4-ConnectX®7 series, and provides RIVERMAX licenses service.

Difference between CPU, GPU and DPU

Functionally, the main difference between the three lies in application scenarios and processing tasks. CPU is widely used for various computing tasks, while GPU is mainly used for graphics computing, and DPU is mainly used for data transmission data processing in data centres.

In terms of architecture, GPUs have more cores and processors than CPUs, and have higher parallel processing capabilities, while DPUs not only have the ability to transmit data but also can manage infrastructure, which enables them to work better together.

Of course, the DPU is not to replace the CPU and GPU, but the three divisions of labour. Among them, CPU is responsible for the definition of the entire IT ecosystem and processing general-purpose computing tasks, GPU is responsible for data-parallel tasks such as graphic images, deep learning, matrix operations and other accelerated computing tasks, and DPU takes on the accelerated processing of other specialised services such as security, networking, and storage.

Conclusion

DPUs have become an important part of computing, alongside central processing units (CPUs) and graphics processing units (GPUs). By integrating DPUs into devices such as Smart NICs, more efficient data transfer and processing can be achieved while reducing the burden on the CPU and GPU, increasing overall system throughput and responsiveness.

Exploring Smart NICs: Features, Types, and How to Choose

In the wave of digital transformation, the importance of network connectivity as the blood vessel for data flow cannot be overstated. The continuous development of network technology and hardware devices has changed the landscape of data centres and cloud computing. Traditional NICs have struggled to meet the growing bandwidth demands, security challenges, and the need for intelligent management. As a result, smart NICs have emerged. This article will delve into the features, types, and differences of smart NICs and how to choose the right option for a given use case.

What is Smart NIC?

Smart NIC, is a network interface card with integrated intelligent processing capabilities. Not only does it have the data transmission capabilities of a traditional NIC, but it also has a built-in high-performance processor (e.g., FPGA, ASIC, or smart chip) and a dedicated acceleration engine that is capable of performing complex data processing tasks such as data encryption, network protocol offloading, and traffic management. This design enables smart NICs to significantly improve network performance and security without increasing the CPU burden.

Functions

  • Packet filtering and load balancing.
  • Quality of Service (QoS) implementation.
  • Storage acceleration, including Remote Direct Memory Access (RDMA), iSCSI, and NVMe over Fabrics.
  • Security features such as firewall processing and Intrusion Detection System (IDS) checks.

Types

There is no fixed way to classify smart NICs, and they can be divided into the following types according to the form adopted for the design of smart NICs:

  1. FPGA-Based Smart NICs:

FPGA (Field Programmable Gate Array) based Smart NICs are highly customisable and programmable. They provide low-latency processing by offloading network tasks, such as packet inspection, encryption, or compression, directly onto the NIC. This flexibility makes FPGA-based intelligent NICs ideal for specific, specialised workloads such as financial trading systems where speed and low latency are critical. They support real-time updates to adapt to changing network requirements without requiring hardware changes. Example: Xilinx Alveo SmartNIC.

  1. ASIC-Based Smart NICs:

ASIC (Application Specific Integrated Circuits) based SmartNICs are designed for specific tasks and provide high performance and efficiency. These smart NICs are typically used for fixed-function tasks such as offloading TCP/IP processing, RDMA (Remote Direct Memory Access), or VXLAN encapsulation/decapsulation. ASIC-based smart NICs offer low power consumption and high throughput, making them ideal for cloud environments and hyperscale data centres. Example: Mellanox (NVIDIA) BlueField-2 Smart NIC.

  1. SoC (System-on-Chip) Based Smart NICs:

These smart NICs integrate multiple processing units (CPUs, GPUs or other accelerators) on a single chip, enabling them to handle complex networking and security functions independently. SoC-based smart NICs are suitable for workloads that require both computing power and networking, such as security functions like firewalls, DDoS protection and encryption. They enable tasks such as deep packet inspection, network virtualisation and telemetry to be handled directly on the NIC. Example: Intel Ethernet 800 Series with Dynamic Device Personalization (DDP).

  1. ARM-Based Intelligent NICs:

ARM-based intelligent NICs integrate ARM processors on the NIC itself to handle compute and network tasks. These processors offload workloads from the host server CPU, reducing CPU overhead and increasing system efficiency. They are widely used in virtualised, containerised and cloud-native environments where network traffic processing can be offloaded to the NIC. example: Marvell ARMADA-based NIC.

FS, as an NVIDIA partner, can provide NVIDIA Ethernet NICs, which are rigorously tested and certified to ensure full compatibility with a wide range of operating systems and hypervisors. In addition, FS offers a complete end-to-end solution supporting InfiniBand and Ethernet networking technologies, providing organisations with the infrastructure needed to support the development deployment implementation and storage requirements of the accelerated computing era.

Application Scenarios

High Performance Computing (HPC): Offload tasks to improve supercomputing performance.

Financial Services: Improve latency for time-sensitive applications such as stock trading.

Telecommunications: Optimising virtual network functions (VNFs) in telecoms networks.

Cloud & Data Centre: In the cloud and data centre space, smart NICs can significantly improve server network performance and security, reduce latency and packet loss, and improve overall quality of service and user experience.

Edge Computing: In edge computing scenarios, smart NICs can support low-latency and high-bandwidth data transmission requirements, while providing strong security protection capabilities to ensure data security and privacy protection for edge devices.

Internet of Things and Smart Cities: In the field of Internet of Things and Smart Cities, smart NICs can connect a variety of smart devices and sensors to achieve rapid data transmission and intelligent processing, providing strong support for city management and services.

Why is a Smart NIC better than a standard NIC?

Smart NICs reduce the burden on host server CPUs for routing, network address translation, telemetry, load balancing, firewalls, and more. It can block DDoS attacks and can be used to manage hard discs/solid-state drives in a similar way to a storage controller. In addition, SmartNICs are great solutions for offloading the data plane. Smart NICs may take on handling tunnelling protocols (e.g. VxLAN) and complex virtual switching. Its ultimate goal is to consume fewer host CPU processor cores while providing a higher-performance solution at a lower cost.

While standard NIC functionality is sufficient to support common network connectivity needs, it falls short when faced with data-intensive applications, virtualised environments, cloud computing and high-performance computing that demand higher performance and functionality.

Of course, there are times when we need to choose between a standard Network NIC and a smart NIC. At this critical juncture, FS offers a range of Intel-based Ethernet adapters to provide our customers with a cost-effective solution. Whether you choose one of our advanced NICs or select a Smart NIC, FS is ready to meet your networking needs and ensure that your network operates in an optimal, secure and efficient manner.

In August, FS introduced its latest portfolio of highly scalable, high-performance original Broadcom® Ethernet adapters. Included are seven Broadcom® NICs supporting a full range of speeds and feeds from 10G to 400G in a standard half-height, half-length form factor, providing enhanced, open, standards-based Ethernet NICs to address connectivity bottlenecks that occur as data centre bandwidth and cluster sizes grow rapidly.

How to choose Smart NICs?

In the ever-evolving world of networking, choosing the right NIC is critical and will have a direct impact on the performance, security and operation of your network and applications. Different use cases and requirements will determine the best choice for you.

Uses

Different workloads benefit from specific smart card features. For example, high-performance computing (HPC), financial trading, AI workloads, or video streaming may require a low-latency, high-throughput NIC with dedicated offload capabilities. Also, if you are managing a virtualised environment, make sure the smart card supports technologies such as SR-IOV (Single Root I/O Virtualization) and OVS (Open vSwitch) offload. These technologies help virtualise the network and reduce CPU overhead.

Speed and Bandwidth

Evaluate your current network speed requirements (10G, 25G, 40G, 100G or even 400G). For data-intensive environments, such as cloud data centres or AI workloads, high-speed smart NICs such as 100G or 400G may be required. Consider choosing higher-speed smart NICs or modular NICs that can be upgraded as your network expands to be future-proof.

Software and Compatibility

Ensure that the smart NIC supports the operating systems in your infrastructure, such as Linux, Windows, or FreeBSD. Choose a smart NIC that integrates with your existing network architecture. For example, if you are using a specific switch vendor, make sure the smart card is compatible with the vendor’s network management tools. In addition, some smart cards come with software development kits (SDKs) or APIs for customisation. If programmability is a priority, make sure the vendor provides good support for custom applications.

Power Consumption

High-performance smart NICs can consume a lot of power. For large-scale deployments, consider the power-to-performance ratio. ASIC-based NICs are typically more energy efficient, while FPGA-based NICs offer flexibility but may consume more power.

Security

If your organisation uses a zero-trust network model, choose a smart card that supports hardware-based security features such as encryption, IPsec offload, and trusted boot mechanisms. Some smart cards also offer real-time telemetry and analytics, enabling you to monitor network traffic, detect anomalies, and quickly respond to potential security threats.

Cost

The cost of smart NICs can vary widely depending on their features and capabilities. ASIC-based cards tend to be more affordable, while FPGA-based cards can be more expensive due to their customizability. Evaluate cost savings in terms of CPU offloading, power efficiency, and performance enhancements. While smart NICs may have higher upfront costs, they can reduce overall infrastructure costs by offloading critical network functions.

Latency and Throughput

Latency is a key factor in applications such as financial trading or HPC. Look for smart NICs that support low-latency packet processing and accelerated I/O to optimise real-time performance. Choosing smart NICs with high throughput capabilities ensures they can handle the expected amount of data without bottlenecks.

Conclusion

As a new chapter in the future of network connectivity, smart NICs are leading the innovation and development of network technology with their excellent performance, strong security capabilities and intelligent management features. In the future, smart NICs will also open up a wider range of application scenarios and market opportunities. In short, the emergence and application of smart NICs will bring more opportunities and challenges to the digital society and intelligent future.

Cloud vs Edge Computing: The Differences You Need to Know

With the deepening of the digital era, Cloud Computing and Edge Computing, as the two hotspots in the current technology field, have changed the traditional mode of data storage and processing in different ways, and together they have shaped a more efficient and intelligent informationized world.

This article will delve into the differences between cloud computing and edge computing to help you gain a deeper understanding of these two concepts.

What is Cloud Computing

Cloud computing is a kind of distributed computing, which refers to the decomposition of huge data calculation and processing procedures into countless small procedures through the network “cloud”, and then processing and analyzing these small procedures through the system composed of multiple servers, and then returning the results to the users.

The core concept of cloud computing is to centralize computing power into large data centres and achieve flexible resource allocation and management through virtualization technology.

Characteristics

Virtualization technology: Cloud computing achieves abstraction of hardware resources through virtualization technology, allowing users to use computing resources more flexibly without caring about the underlying hardware details.

Elasticity and scalability: Users are allowed to rapidly expand or reduce computing resources according to their needs, realizing the elastic use of resources and avoiding the waste of resources.

On-demand services: Users can purchase and use various services provided by cloud computing according to their needs, without investing large amounts of money in advance to build their computing infrastructure.

Easy integration and standardization: Support for multiple standards and protocols facilitates the development of cross-platform applications.

What is Edge Computing

Edge computing emphasises data processing and storage at or near the source of data generation. In an ideal environment, edge computing refers to analysing and processing data near the source of data generation without data flow, reducing network traffic and response time.

Features

Low Latency: Edge computing processes data at the source of data generation, reducing the distance and lowering the latency of data transmission, enabling applications to respond faster to user requests.

Enhanced data security: Data is processed locally, reducing the need for transmission to the cloud, thereby reducing the risk of potential data leakage.

Network and storage efficiency: Edge computing occurs at the edge layer, halfway between the cloud and device layers, with the obvious benefit of being closer to the user, reducing bandwidth and storage demands on the central data centre.

Cloud Computing VS. Edge Computing

Edge computing and cloud computing are closely related in many ways. Edge computing is usually based on cloud computing, where computing and storage resources are deployed at the edge of the network to improve computing efficiency and user experience. Cloud computing is usually based on edge computing, where computing and storage resources are centrally managed to improve computing efficiency and reduce costs. In the future, edge computing and cloud computing will converge with each other and jointly drive the development of the computing field.

Differences Between Cloud Computing and Edge Computing

Data Processing Location

Cloud computing emphasizes the centralized processing of data in a central data centre, which is accessed by users via the Internet so that they can use the services provided by the cloud. In contrast, edge computing pushes data processing to edge devices closer to the data source, such as IoT devices, edge servers, etc., for lower latency and more efficient data processing.

Latency and Response Time

Cloud computing typically involves transmitting data to a remote data centre for processing, so there can be high latency during data transmission and processing. In contrast, edge computing pushes data processing closer to the data source, enabling faster response times in scenarios where real-time requirements are high.

Availability and Stability

Cloud computing delivers services through large data centres with powerful computing and storage capabilities, but in some cases can be affected by network failures or data centre failures. Edge computing, on the other hand, provides services through computing resources distributed on edge devices, which can operate independently in some cases.

Application Scenarios

Cloud computing is more suitable for scenarios that require large-scale computing and storage, such as big data analysis and machine intelligence training. Edge computing is more suitable for scenarios that require high real-time and low latency, such as IoT, autonomous driving, and industrial automation.

FS, a leading solution provider, has launched a next-generation network solution for autonomous driving, based on PicOS® switches and AmpCon™ management platform, which delivers real-time processing to enable self-driving cars to drive in a variety of environments. FS provides a range of customized hardware, easy-to-deploy application and management software, and end-to-end services for the solution. With these, organizations can instantly respond to customer needs, run their networks with maximum efficiency and security, and bring innovation in the field of autonomous driving.

Synergistic Applications

Cloud and edge computing are not mutually exclusive but can work together to take full advantage of their respective strengths. By distributing data processing between edge devices and cloud data centres, a more flexible and efficient computing architecture can be achieved. Here are some use cases:

  • In a smart factory, sensors and devices collect and analyze production data in real-time through edge computing to improve productivity. Meanwhile, cloud computing can be used for centralized management of global data, long-term analysis and optimization.
  • In healthcare, edge computing can monitor patient vital signs in real-time and provide rapid emergency treatment. Cloud computing, on the other hand, can be used to store and analyze large-scale medical data to support medical research and precision medicine.
  • In intelligent transportation systems, edge devices such as traffic cameras and sensors can monitor traffic conditions in real-time and respond quickly. Cloud computing can then analyze historical traffic data to optimize traffic flow and improve urban traffic efficiency.
  • In smart city and smart home scenarios, edge computing can be used for real-time interaction and data processing, while cloud computing can be used for data storage and analysis.
  • In virtual reality and augmented reality scenarios, edge computing can be used for real-time rendering and interaction, while cloud computing can be used to store and process large-scale virtual reality data.

Conclusion

To summarize, cloud computing focuses on the “cloud”, while edge computing focuses on the “end”. Specifically, edge computing is the processing of data, the operation of applications, and even the realization of some functional services from the central server to the nodes on the edge of the network.

Cloud computing is an orchestrator, responsible for big data analysis of long-period data, and able to operate in areas such as cyclical maintenance and business decision-making.

However, with the development of the digital era, they are also gradually forming a trend of synergistic applications, giving full play to their respective advantages and providing a more flexible and efficient computing architecture.

Cloud Computing: IaaS, PaaS, and SaaS Explained

Whether for governments, businesses, or consumers, we all use various clouds almost daily. Cloud computing is now a key part of modern IT systems. Cloud service models are important for creating and providing cloud services. Four main types of cloud computing include private cloud, public cloud, hybrid cloud, and multi-cloud.

Cloud computing has three main service models. They are Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS). These are the main cloud computing service models today. This article will delve into these three models, exploring their features, advantages, and suitability for different scenarios.

Cloud Computing Deployment Models

Cloud computing is a new computing model based on the internet. It integrates technologies such as distributed computing, parallel computing, network storage, virtualisation, and load balancing.

It uses many distributed computers instead of local or remote servers. This provides computing resources and services that are scalable, reliable, flexible, and secure. These resources are available when needed.

Cloud Computing Deployment Models describe the configuration methods for cloud computing resources and services, explaining how different environments deploy cloud infrastructure. These models help organisations decide how to deploy and manage their computing resources across various cloud environments. The main cloud computing deployment models include:

Public Cloud

Cloud-based applications are entirely deployed in the cloud, with all components running in the cloud. Two types of cloud-based applications exist. Some developers create them in the cloud, while others migrate existing systems to the cloud. This helps them take advantage of cloud benefits.

Developers can build cloud-based applications using basic infrastructure components. They can also use higher-level services. These services simplify the core infrastructure’s management, design, and scaling.

Hybrid Cloud

Hybrid deployment connects infrastructure and applications between cloud-based resources and existing non-cloud resources. The most common hybrid deployment method adds a cloud layer to an organization’s infrastructure. It connects cloud resources with internal systems.

Private Cloud

Deploying resources locally using virtualisation and resource management tools is often called a “private cloud.” While local deployment cannot offer many cloud computing advantages, this approach sometimes provides dedicated resources. In most cases, this deployment model is similar to traditional IT infrastructure, with application management and virtualisation technologies used to maximise resource utilisation.

Multi-Cloud

Multi-cloud refers to a cloud architecture that integrates multiple cloud services. Various cloud providers supply these services. They can either be public clouds or private clouds, depending on the specific use case.

Every hybrid cloud is a multi-cloud, yet not every multi-cloud is a hybrid. When various clouds link through some form of integration or orchestration, a multi-cloud transforms into a hybrid cloud.

You can plan a multi-cloud environment for better control over sensitive data. It can also serve as extra storage to improve disaster recovery. Sometimes, it happens by accident because of shadow IT. This shows that more companies are using multi-cloud to boost security and performance by reaching more environments.

Cloud Computing Service Models

Cloud computing models, or service models, currently fall into three main categories: IaaS, PaaS, and SaaS. Each model represents a distinct part of the cloud computing stack.

Unveiling the Secrets of Server Hardware Composition

In the digital age, servers are the core foundation supporting the internet and various technological applications. Whether browsing the web, sending emails, or watching online videos, a vast and complex server system operates behind the scenes. Despite enjoying digital conveniences, few people have an in-depth understanding of server hardware. This article will take you into the mysterious world of servers, exploring how they are composed of various hardware components.

Server Basics: Understanding the Core Components and Concepts

A server, a term we frequently encounter in daily life, is essentially the central nervous system of the internet. It operates tirelessly, ensuring our digital activities run smoothly. A server is a high-performance computer with a fast CPU, reliable long-term operation, and powerful external data throughput. Compared to ordinary computers, servers have significant advantages in processing power, stability, reliability, security, scalability, and manageability. They are the unsung heroes supporting our digital lives, not just the core of data processing.The hardware makeup of a server involves several critical components, including the central processing unit (CPU), memory (RAM), storage devices (hard drives and solid-state drives), motherboard, power supply unit, and network interface cards. These components work together to provide robust computing and storage capabilities.

Central Processing Unit (CPU)

The CPU is the brain of the server, responsible for executing computational tasks and processing data. The primary difference between server processors and ordinary desktop processors lies in their design focus; server processors emphasise multi-core performance and high parallel processing capabilities. The CPU’s performance directly impacts the server’s overall computational power and response speed. Common CPU brands in servers include Intel and AMD (Advanced Micro Devices). Multi-core processors are widely used in servers as they can handle multiple tasks simultaneously, enhancing concurrency and efficiency.

  • Core Count: Server CPUs typically have multiple cores, ranging from 4 to 64 or more.
  • Hyper-Threading Technology: Technologies like Intel’s Hyper-Threading allow a single core to handle two threads simultaneously, further improving efficiency.

Random-Access Memory (RAM)

Random-Access Memory is where a server temporarily stores data and programs. When applications running on the server need to read or write data, it is temporarily loaded into Random-Access Memory for faster access and processing. The size and speed of memory are crucial to the server’s performance. High-capacity and high-speed Random-Access Memory helps avoid memory bottlenecks and improves the server’s operational efficiency.

  • Type: Servers typically use ECC (Error-Correcting Code) memory, which can detect and correct common types of data corruption, ensuring data accuracy and system stability.
  • Capacity: Server memory capacity usually ranges from tens of gigabytes to several terabytes, depending on the server’s purpose and workload requirements.

Storage Devices

Servers are usually equipped with various storage devices, including hard disk drives (HDD) and solid-state drives (SSD). HDDs are traditional storage devices that offer large storage capacities at lower prices. SSDs, on the other hand, are favoured for their high-speed read/write capabilities and lower access times, particularly in scenarios requiring rapid data retrieval. Server administrators typically select the appropriate storage configuration based on needs and budget. The choice of storage devices directly impacts data access speed and capacity.

  • Hard Disk Drives (HDD): Provide large storage space at a lower cost, suitable for storing large volumes of data.
  • Solid-State Drives (SSD): Offer fast speeds, short response times, and high durability, ideal for caching and frequently accessed data.
  • NVMe SSDs: Use high-speed PCIe channels and are faster than regular SSDs, suitable for extremely high-speed data processing needs.

Motherboard

Finding the Ideal Server: Key Considerations and Tips

After understanding the various types of servers, the wide range of options can make it challenging for buyers to decide. This section outlines some principles or factors to help buyers choose the most suitable server.

Stability Principle

Stability is the most crucial aspect of a server. To ensure the normal operation of the network, it is essential to guarantee the stable running of the server. If the server fails to operate correctly, it can result in irreparable losses.

Specificity Principle

Different network services have varying requirements for server configurations. For instance, file servers, FTP servers, and video-on-demand servers require large memory, high-capacity, and high read-rate disks, as well as sufficient network bandwidth, but do not need high CPU clock speeds. Conversely, database servers require high-performance CPUs and large memory, preferably with a multi-CPU architecture, but do not have high demands for hard disk capacity.

Web servers also require large memory but do not need high disk capacity or CPU clock speeds. Therefore, users should choose server configurations based on the specific network applications they intend to use.

Miniaturisation Principle

Except for providing advanced network services that necessitate high-performance servers, it is advisable not to purchase high-performance servers just to host all services on a single server. Firstly, higher-performance servers are more expensive and offer lower cost-effectiveness. Secondly, despite a certain level of stability, if a server fails, it will disrupt all services. Thirdly, when multiple services experience high concurrent access, it can significantly affect response speed and even cause system crashes.

Therefore, it is recommended to configure different servers for different network services to distribute access pressure. Alternatively, purchasing several lower-spec servers and using load balancing or clustering can meet network service needs, saving on costs while greatly improving network stability.

Sufficiency Principle

Server configurations are continually improving, and prices are constantly decreasing. Therefore, it is essential to meet current service needs with a slightly forward-looking approach. When existing servers can no longer meet network demands, they can be repurposed for services with lower performance requirements (such as DNS or FTP servers), appropriately expanded, or used in a cluster to enhance performance. New servers can then be purchased for new network needs.

Rack Principle

When a network requires multiple servers, it is advisable to consider rack-mounted servers. Rack-mounted servers can be uniformly installed in standard cabinets, reducing space occupancy and eliminating the need for multiple monitors and keyboards. More importantly, they facilitate power management and clustering operations.

Conclusion

Choosing the right server architecture is a strategic decision tailored to specific needs. Each type of server has its advantages and disadvantages, depending on an organisation’s particular circumstances and goals. In practice, some organisations opt for a hybrid deployment, utilising different server architectures based on workload requirements. This hybrid model can maximise the strengths of various architectures, providing more flexible solutions. We hope this article helps readers gain a comprehensive understanding of different server types to better meet their business needs.

Network Virtualisation: NVGRE vs. VXLAN Explained

The rise of virtualisation technology has revolutionised data centres, enabling the operation of multiple virtual machines on the same physical infrastructure. However, traditional data centre network designs are not well-suited to these new applications, necessitating a new approach to address these challenges. NVGRE and VXLAN were created to meet this need. This article delves into NVGRE and VXLAN, exploring their differences, similarities, and advantages in various scenarios.

Unleashing the Power of NVGRE Technology

NVGRE (Network Virtualization using Generic Routing Encapsulation) is a network virtualisation method designed to overcome the limitations of traditional VLANs in complex virtual environments.

How It Works

NVGRE encapsulates data packets by adding a Tenant Network Identifier (TNI) to the packet, transmitting it over existing IP networks, and then decapsulating and delivering it on the target host. This enables large-scale virtual networks to be more flexible and scalable on physical infrastructure.

1.Tenant Network Identifier (TNI)

NVGRE introduces a 24-bit TNI to identify different virtual networks or tenants. Each TNI corresponds to a separate virtual network, allowing multiple virtual networks to operate on the same physical infrastructure without interference.

2. Packet Encapsulation

Source MAC Address: The MAC address of the sending VM.

Destination MAC Address: The MAC address of the receiving VM.

TNI: The 24-bit virtual network identifier.

Original Ethernet Frame: Includes the source MAC address, destination MAC address, Ethernet protocol type (usually IPv4 or IPv6), etc.

Data packets are encapsulated into NVGRE packets for communication between VMs.

3. Transport Network

NVGRE packets are transmitted over existing IP networks, including physical or virtual networks. The IP header information is used for routing, while the TNI identifies the target virtual network.

4. Decapsulation

When NVGRE packets reach the host of the target VM, the host decapsulates them, extracting the original Ethernet frame and delivering it to the target VM.

5. MAC Address Table Maintenance

NVGRE hosts maintain a MAC address table to map VM MAC addresses to TNIs. When a host receives an NVGRE packet, it looks up the MAC address table to determine which VM to deliver the packet to.

6. Broadcast and Multicast Support

NVGRE uses broadcast and multicast to support communication within virtual networks, allowing VMs to perform broadcast and multicast operations for protocols like ARP and Neighbor Discovery.

Features

  • Network Virtualisation Goals: NVGRE aims to provide a larger number of VLANs for multi-tenancy and load balancing, overcoming the limited VLAN capacity of traditional networks.
  • Encapsulation and Tunneling: Uses encapsulation and tunneling to isolate virtual networks, making VM communication appear direct without considering the underlying physical network.
  • Cross-Data Centre Scalability: Designed to support cross-location virtual networks, ideal for distributed data centre architectures.

A Comprehensive Look at VXLAN Technology

VXLAN (Virtual Extensible LAN) is a network virtualisation technology designed to address the shortage of virtual networks in large cloud data centres.

How It Works

VXLAN encapsulates data packets by adding a Virtual Network Identifier (VNI), transmitting them over existing IP networks, and then decapsulating and delivering them on the target host.

1.Virtual Network Identifier (VNI)

VXLAN introduces a 24-bit VNI to distinguish different virtual networks. Each VNI represents a separate virtual network, allowing multiple virtual networks to operate on the same physical infrastructure without interference.

2.Packet Encapsulation

Source IP Address: The IP address of the sending VM.

Destination IP Address: The IP address of the receiving VM.

UDP Header: Contains source and destination port information to identify VXLAN packets.

VNI: The 24-bit virtual network identifier.

Original Ethernet Frame: Includes the source MAC address, destination MAC address, Ethernet protocol type, etc.

Data packets are encapsulated into VXLAN packets for communication between VMs.

3.Transport Network
VXLAN packets are transmitted over existing IP networks. The IP header information is used for routing, while the VNI identifies the target virtual network.

4.Decapsulation
When VXLAN packets reach the host of the target VM, the host decapsulates them, extracting the original Ethernet frame and delivering it to the target VM.

5.MAC Address Table Maintenance
VXLAN hosts maintain a MAC address table to map VM MAC addresses to VNIs. When a host receives a VXLAN packet, it looks up the MAC address table to determine which VM to deliver the packet to.

6.Broadcast and Multicast Support
VXLAN uses multicast to simulate broadcast and multicast behaviour within virtual networks, supporting protocols like ARP and Neighbor Discovery.

Features

  • Expanded VLAN Address Space: Extends VLAN identifier capacity from 4096 to 16 million with a 24-bit segment ID.
  • Virtual Network Isolation: Allows multiple virtual networks to coexist on the same infrastructure, each with a unique segment ID.
  • Multi-Tenancy Support: Ideal for environments where different tenants need isolated virtual networks.
  • Layer 2 and 3 Extension: Supports complex network topologies and routing configurations.
  • Industry Support: Widely supported by companies like Cisco, VMware, and Arista Networks.

NVGRE vs VXLAN: Uncovering the Best Virtualization Tech

NVGRE and VXLAN are both technologies for virtualising data centre networks, aimed at addressing issues in traditional network architectures such as isolation, scalability, and performance. While their goals are similar, they differ in implementation and several key aspects.

Supporters and Transport Protocols

NVGRE is supported mainly by Microsoft, using GRE as the transport protocol. VXLAN is driven by Cisco, using UDP.

Packet Format

VXLAN packets have a 24-bit VNI for 16 million virtual networks. NVGRE uses the GRE header’s lower 24 bits as the TNI, also supporting 16 million virtual networks.

Transmission Method

VXLAN uses multicast to simulate broadcast and multicast for MAC address learning and discovery. NVGRE uses multiple IP addresses for enhanced load balancing without relying on flooding and IP multicast.

Fragmentation

NVGRE supports fragmentation to manage MTU sizes, while VXLAN typically requires the network to support jumbo frames and does not support fragmentation.

Conclusion

VXLAN and NVGRE represent significant advancements in network virtualisation, expanding virtual network capacity and enabling flexible, scalable, and high-performance cloud and data centre networks. With support from major industry players, these technologies have become essential for building agile virtualised networking environments.

Businesses are growing and networks are becoming more complex. Single-device solutions are having trouble meeting the high availability and performance requirements of modern data centres. To address this, two horizontal virtualisation technologies have emerged: Stacking and Multichassis Link Aggregation Group (MLAG). This article compares Stacking and MLAG. It discusses their principles, features, advantages, and disadvantages. This comparison can help you choose the best option for your network environment.

Understanding Stacking Technology

Stacking technology involves combining multiple stackable devices into a single logical unit. Users can control and use multiple devices together, increasing ports and switching abilities while improving reliability with mutual backup between devices.

Advantages of Stacking:

  • Simplified Management: Managed via a single IP address, reducing management complexity. Administrators can configure and monitor the entire stack from one interface.
  • Increased Port Density: Combining multiple switches offers more ports, meeting the demands of large-scale networks.
  • Seamless Redundancy: If one stack member fails, others seamlessly take over, ensuring high network availability.
  • Enhanced Performance: Increased interconnect bandwidth among switches improves data exchange efficiency and performance.

Unlocking the Power of MLAG Technology

Multichassis Link Aggregation Group (MLAG) is a newer cross-device link aggregation technology. It allows two access switches to negotiate link aggregation as if they were one device. This cross-device link aggregation enhances reliability from the single-board level to the device level, making MLAG suitable for modern network topologies requiring redundancy and high availability.

Advantages of MLAG:

VXLAN VS. MPLS: From Data Centre to Metropolitan Area Network

In recent years, the advancement of cloud computing, virtualisation, and containerisation technologies has driven the adoption of network virtualisation. Both MPLS and VXLAN leverage virtualisation concepts to create logical network architectures, enabling more complex and flexible domain management. However, they serve different purposes. This article will compare VXLAN and MPLS, explaining why VXLAN is more popular than MPLS in metropolitan and wide area networks.

Understanding VXLAN and MPLS: Key Concepts Unveiled

VXLAN

Virtual Extensible LAN (VXLAN) encapsulates Layer 2 Ethernet frames within Layer 3 UDP packets, enabling devices and applications to communicate over a large physical network as if they were on the same Layer 2 Ethernet network. VXLAN technology uses the existing Layer 3 network as an underlay to create a virtual Layer 2 network, known as an overlay. As a network virtualisation technology, VXLAN addresses the scalability challenges associated with large-scale cloud computing setups and deployments.

MPLS

Multi-Protocol Label Switching (MPLS) is a technology that uses labels to direct data transmission quickly and efficiently across open communication networks. The term “multi-protocol” indicates that MPLS can support various network layer protocols and is compatible with multiple Layer 2 data link layer technologies. This technology simplifies data transmission between two nodes by using short path labels instead of long network addresses. MPLS allows the addition of more sites with minimal configuration. It is also independent of IP, merely simplifying the implementation of IP addresses. MPLS over VPN adds an extra layer of security since MPLS itself lacks built-in security features.

Data Centre Network Architecture Based on MPLS

MPLS Layer 2 VPN (L2VPN) provides Layer 2 connectivity across a Layer 3 network, but it requires all routers in the network to be IP/MPLS routers. Virtual networks are isolated using MPLS pseudowire encapsulation and can stack MPLS labels, similar to VLAN tag stacking, to support a large number of virtual networks.

IP/MPLS is commonly used in telecom service provider networks, so many service providers’ L2VPN services are implemented using MPLS. These include point-to-point L2VPN and multipoint L2VPN implemented according to the Virtual Private LAN Service (VPLS) standard. These services typically conform to the MEF Carrier Ethernet service definitions of E-Line (point-to-point) and E-LAN (multipoint).

Because MPLS and its associated control plane protocols are designed for highly scalable Layer 3 service provider networks, some data centre operators have adopted MPLS L2VPN in their data centre networks to overcome the scalability and resilience limitations of Layer 2 switched networks, as shown in the diagram.

Why is VXLAN Preferred Over MPLS in Data Centre Networks?

Considering the features and applications of both technologies, the following points summarise why VXLAN is more favoured:

Cost of MPLS Routers

For a long time, some service providers have been interested in building cost-effective metropolitan networks using data centre-grade switches. Over 20 years ago, the first generation of competitive metro Ethernet service providers, like Yipes and Telseon, built their networks using the most advanced gigabit Ethernet switches available in enterprise networks at the time. However, such networks struggled to provide the scalability and resilience required by large service providers (SPs). Consequently, most large SPs shifted to MPLS (as shown in the diagram below). However, MPLS routers are more expensive than ordinary Ethernet switches, and this cost disparity has persisted over the decades. Today, data centre-grade switches combined with VXLAN overlay architecture can largely eliminate the shortcomings of pure Layer 2 networks without the high costs of MPLS routing, attracting a new wave of SPs.

Tight Coupling Between Core and Edge

MPLS-based VPN solutions require tight coupling between edge and core devices, meaning every node in the data centre network must support MPLS. In contrast, VXLAN only requires a VTEP (VXLAN Tunnel Endpoint) in edge nodes (e.g., leaf switches) and can use any IP-capable device or IP transport network to implement data centre spine and data centre interconnect (DCI).

MPLS Expertise

Outside of large service providers, MPLS technology is challenging to learn, and relatively few network engineers can easily build and operate MPLS-based networks. VXLAN, being simpler, is becoming a fundamental technology widely mastered by data centre network engineers.

Advancements in Data Centre Switching Technology

Modern data centre switching chips have integrated numerous functions that make metro networks based on VXLAN possible. Here are two key examples:

  • Hardware-based VTEP supporting line-rate VXLAN encapsulation.
  • Expanded tables providing the routing and forwarding scale required to create resilient, scalable Layer 3 underlay networks and multi-tenant overlay services.

Additionally, newer data centre-grade switches have powerful CPUs capable of supporting advanced control planes crucial for extended Ethernet services, whether it’s BGP EVPN (a protocol-based approach) or an SDN-based protocol-less control plane. Therefore, in many metro network applications, specialised (and thus high-cost) routing hardware is no longer necessary.

VXLAN Overlay Architecture for Metropolitan and Wide Area Networks

Overlay networks have been widely adopted in various applications such as data centre networks and enterprise SD-WAN. A key commonality among these overlay networks is their loose coupling with the underlay network. Essentially, as long as the network provides sufficient capacity and resilience, the underlay network can be constructed using any network technology and utilise any control plane. The overlay is only defined at the service endpoints, with no service provisioning within the underlay network nodes.

One of the primary advantages of SD-WAN is its ability to utilise various networks, including broadband or wireless internet services, which are widely available and cost-effective, providing sufficient performance for many users and applications. When VXLAN overlay is applied to metropolitan and wide area networks, similar benefits are also realised, as depicted in the diagram.

When building a metropolitan network to provide services like Ethernet Line (E-Line), Multipoint Ethernet Local Area Network (E-LAN), or Layer 3 VPN (L3VPN), it is crucial to ensure that the Underlay can meet the SLA (Service Level Agreement) requirements for such services.

VXLAN-Based Metropolitan Network Overlay Control Plane Options

So far, our focus has mainly been on the advantages of VXLAN over MPLS in terms of network architecture and capital costs, i.e., the advantages of the data plane. However, VXLAN does not specify a control plane, so let’s take a look at the Overlay control plane options.

The most prominent control plane option for creating VXLAN Overlay and providing Overlay services should be BGP EVPN, which is a protocol-based approach that requires service configuration in each edge node. The main drawback of BGP EVPN is the complexity of operations.

Another protocol-less approach is using SDN and services defined in an SDN controller to programme the data plane of each edge node. This approach eliminates much of the operational complexity of protocol-based BGP EVPN. Nonetheless, the centralised SDN controller architecture, suitable for single-site data centre architectures, presents significant scalability and resilience issues when implemented in metropolitan and wide area networks. As a result, it’s unclear whether it’s a superior alternative to MPLS for metropolitan networks.

There’s also a third possibility—decentralised or distributed SDN, in which the SDN controller’s functionality is duplicated and spread across the network. This can also be referred to as a “controller-less” SDN because it doesn’t necessitate a separate controller server/device, thereby completely resolving the scalability and resilience problems associated with centralised SDN control while maintaining the advantages of simplified and expedited service configuration.

Deployment Options

Due to VXLAN’s ability to decouple Overlay services delivery from the Underlay network, it creates deployment options that MPLS cannot match, such as virtual service Overlays on existing IP infrastructure, as shown in the diagram. VXLAN-based switch deployments at the edge of existing networks, scalable according to business requirements, allow for the addition of new Ethernet and VPN services and thus generate new revenue without altering the existing network.

VXLAN Overlay Deployment on Existing Metropolitan Networks

The metropolitan network infrastructure shown in Figure 2 can support all services offered by an MPLS-based network, including commercial internet, Ethernet and VPN services, as well as consumer triple-play services. Moreover, it completely eliminates the costs and complexities associated with MPLS.

Conclusion

VXLAN has become the most popular overlay network virtualization protocol in data centre network architecture, surpassing many alternative solutions. When implemented with hardware-based VTEPs in switches and DPUs, and combined with BGP EVPN or SDN control planes and network automation, VXLAN-based overlay networks can provide the scalability, agility, high performance, and resilience required for distributed cloud networks in the foreseeable future.

Network Virtualisation: VXLAN Benefits & Differences

With the rapid development of cloud computing and virtualisation technologies, data centre networks are facing increasing challenges. Traditional network architectures have limitations in meeting the demands of large-scale data centres, particularly in terms of scalability, isolation, and flexibility. To overcome these limitations and provide better performance and scalability for data centre networks, VXLAN (Virtual Extensible LAN) has emerged as an innovative network virtualisation technology. This article will detail the principles and advantages of VXLAN, its applications in data centre networks, and help you understand the differences between VXLAN and VLAN.

The Power of VXLAN: Transforming Data Centre Networks

VXLAN is a network virtualisation technology designed to overcome the limitations of traditional Ethernet, offering enhanced scalability and isolation. It enables the creation of a scalable virtual network on existing infrastructure, allowing virtual machines (VMs) to move freely within a logical network, regardless of the underlying physical network topology. VXLAN achieves this by creating a virtual Layer 2 network over an existing IP network, encapsulating traditional Ethernet frames within UDP packets for transmission. This encapsulation allows VXLAN to operate on current network infrastructure without requiring extensive modifications.

VXLAN uses a 24-bit VXLAN Network Identifier (VNI) to identify virtual networks, allowing multiple independent virtual networks to coexist simultaneously. The destination MAC address of a VXLAN packet is replaced with the MAC address of the virtual machine or physical host within the VXLAN network, enabling communication between virtual machines. VXLAN also supports multipath transmission through MP-BGP EVPN and provides multi-tenant isolation within the network.

How it works

  • Encapsulation: When a virtual machine (VM) sends an Ethernet frame, the VXLAN module encapsulates it in a UDP packet. The source IP address of the packet is the IP address of the host where the VM resides, and the destination IP address is that of the remote endpoint of the VXLAN tunnel. The VNI field in the VXLAN header identifies the target virtual network. The UDP packet is then transmitted through the underlying network to reach the destination host.
  • Decapsulation: Upon receiving a VXLAN packet, the VXLAN module parses the UDP packet header to extract the encapsulated Ethernet frame. By examining the VNI field, the VXLAN module identifies the target virtual network and forwards the Ethernet frame to the corresponding virtual machine or physical host.

This process of encapsulation and decapsulation allows VXLAN to transparently transport Ethernet frames over the underlying network, while simultaneously providing logically isolated virtual networks.

Key Components

  • VXLAN Identifier (VNI): Used to distinguish different virtual networks, similar to a VLAN identifier.
  • VTEP (VXLAN Tunnel Endpoint): A network device responsible for encapsulating and decapsulating VXLAN packets, typically a switch or router.
  • Control Plane and Data Plane: The control plane is responsible for establishing and maintaining VXLAN tunnels, while the data plane handles the actual data transmission.

The Benefits of VXLAN: A Changer for Virtual Networks

VXLAN, as an emerging network virtualisation technology, offers several advantages in data centre networks:

Scalability

VXLAN uses a 24-bit VNI identifier, supporting up to 16,777,216 virtual networks, each with its own independent Layer 2 namespace. This scalability meets the demands of large-scale data centres and supports multi-tenant isolation.

Cross-Subnet Communication

Traditional Ethernet relies on Layer 3 routers for forwarding across different subnets. VXLAN, by using the underlying IP network as the transport medium, enables cross-subnet communication within virtual networks, allowing virtual machines to migrate freely without changing their IP addresses.

Flexibility

VXLAN can operate over existing network infrastructure without requiring significant modifications. It is compatible with current network devices and protocols, such as switches, routers, and BGP. This flexibility simplifies the creation and management of virtual networks.

Multipath Transmission

VXLAN leverages multipath transmission (MP-BGP EVPN) to achieve load balancing and redundancy in data centre networks. It can choose the optimal path for data transmission based on network load and path availability, providing better performance and reliability.

Security

VXLAN supports tunnel encryption, ensuring data confidentiality and integrity over the underlying IP network. Using secure protocols (like IPsec) or virtual private networks (VPNs), VXLAN can offer a higher level of data transmission security.

VXLAN vs. VLAN: Unveiling the Key Differences

VXLAN (Virtual Extensible LAN) and VLAN (Virtual Local Area Network) are two distinct network isolation technologies that differ significantly in their implementation, functionality, and application scenarios.

Implementation

VLAN: VLAN is a Layer 2 (data link layer) network isolation technology that segments a physical network into different virtual networks using VLAN identifiers (VLAN IDs) configured on switches. VLANs use VLAN tags within a single physical network to identify and isolate different virtual networks, achieving isolation between different users or devices.

VXLAN: VXLAN is a Layer 3 (network layer) network virtualisation technology that extends Layer 2 networks by creating virtual tunnels over an underlying IP network. VXLAN uses VXLAN Network Identifiers (VNIs) to identify different virtual networks and encapsulates original Ethernet frames within UDP packets to enable communication between virtual machines, overcoming physical network limitations.

Functionality

VLAN: VLANs primarily provide Layer 2 network segmentation and isolation, allowing a single physical network to be divided into multiple virtual networks. Different VLANs are isolated from each other, enhancing network security and manageability.

VXLAN: VXLAN not only provides Layer 2 network segmentation but also creates virtual networks over an underlying IP network, enabling extensive dynamic VM migration and inter-data centre communication. VXLAN offers greater network scalability and flexibility, making it suitable for large-scale cloud computing environments and virtualised data centres.

Application Scenarios

VLAN: VLANs are suitable for small to medium-sized network environments, commonly found in enterprise LANs. They are mainly used for organisational user segmentation, security isolation, and traffic management.

VXLAN: VXLAN is ideal for large data centre networks, especially in cloud computing environments and virtualised data centres. It supports large-scale dynamic VM migration, multi-tenant isolation, and network scalability, providing a more flexible and scalable network architecture.

These distinctions highlight how VXLAN and VLAN cater to different networking needs and environments, offering tailored solutions for varying levels of network complexity and scalability.

Enhancing Data Centres with VXLAN Technology

The application of VXLAN enhances the flexibility, efficiency, and security of data centre networks, forming a crucial part of modern data centre virtualisation. Here are some typical applications of VXLAN in data centres:

Virtual Machine Migration

VXLAN allows virtual machines to migrate freely between different physical hosts without changing IP addresses. This flexibility and scalability are vital for achieving load balancing, resource scheduling, and fault tolerance in data centres.

Multi-Tenant Isolation

By using different VNIs, VXLAN can divide a data centre into multiple independent virtual networks, ensuring isolation between different tenants. This isolation guarantees data security and privacy for tenants and allows each tenant to have independent network policies and quality of service guarantees.

Inter-Data Centre Connectivity

VXLAN can extend across multiple data centres, enabling the establishment of virtual network connections between them. This capability supports resource sharing, business expansion, and disaster recovery across data centres.

Cloud Service Providers

VXLAN helps cloud service providers build highly scalable virtualised network infrastructures. By using VXLAN, cloud service providers can offer flexible virtual network services and support resource isolation and security in multi-tenant environments.

Virtual Network Functions (VNF)

Combining VXLAN with Network Functions Virtualisation (NFV) enables the deployment and management of virtual network functions. VXLAN serves as the underlying network virtualisation technology, providing flexible network connectivity and isolation for VNFs, thus facilitating rapid deployment and elastic scaling of network functions.

Conclusion

In summary, VXLAN offers powerful scalability, flexibility, and isolation, providing new directions and solutions for the future development of data centre networks. By utilising VXLAN, data centres can achieve virtual machine migration, multi-tenant isolation, inter-data centre connectivity, and enhanced support for cloud service providers.
