What equipment is used in SD WAN networking? 5

With the acceleration of enterprise digital transformation, SD-WAN technology has gradually become a popular choice for enterprise network construction. What devices are needed to implement SD-WAN networking?

The SD-WAN router is the core device of SD-WAN networking, which can integrate a variety of network connections, including MPLS, Internet, 4G and 5G, etc. At the same time, SD-WAN routers can intelligently select the optimal path based on the needs of the application, improving network performance and reliability.

The SD-WAN controller is the management center of the SD-WAN network, which can centrally manage and configure the SD-WAN router. With the SD-WAN controller, administrators can visualize the network topology, optimize applications, and deliver security policies.

SD-WAN edge devices are branch access devices for SD-WAN networking, which can realize network access and application optimization of branch offices. SD-WAN edge devices typically include SD-WAN routers, switches, firewalls, and other functions.

The SD-WAN management platform is an O&M management tool for SD-WAN networking, which can implement network performance monitoring, troubleshooting, and security event management. Through the SD-WAN management platform, administrators can find and solve network problems in a timely manner to ensure network stability and security.

In summary, the devices required for SD-WAN networking include SD-WAN routers, SD-WAN controllers, SD-WAN edge devices, and SD-WAN management platforms. These devices can work together to make the network intelligent, reliable, and secure. If you are considering SD-WAN networking, you may wish to learn about the features and functions of these devices and choose the SD-WAN solution that is suitable for your enterprise.

The next phase of SD-WAN will be based on the Common CPE (UCPE) approach. Currently, there are many different deployment options for SD-WAN. These products include virtual CPE implementations, off-the-shelf UCPE platforms, and fully managed SD-WAN services.

UCPE is another word for server virtualization, which is not something new, they were not invented by network departments and models. SD-WAN will move in the direction of UCPE. It's just a matter of time.

When first deploying SD-WAN, the vendor provided a pre-integrated turnkey.

products, and easy to deploy. These hardware devices meet the needs of end users, such as connecting and managing connections between branch offices, but they can't be easily upgraded or deployed with new capabilities. Instead, they must be thrown away and replaced.

But for some, providing SD-WAN as a hardware appliance is a necessary first step as it supports the transition from legacy systems to other approaches, including over-the-top (OTT) platforms and UCPE platforms.

The KNX system adopts IP networking and can also access 14,400 devices.

Customer premises equipment (CPE) refers to the network terminal equipment located on the user side, which is used to interconnect services with telecom operators, and is an important part of the solution of the customer service provider, which provides various services through the use of dedicated integration links.

The problem with traditional CPE equipment is that it is inflexible and costly, and installation and maintenance require service providers to deploy network technicians, which is time-consuming and very expensive. Network infrastructure equipment has long consisted of specialized equipment from different vendors, such as routers from one vendor and firewalls, WAN accelerators, and wireless LAN controllers from another.

As a result, the industry has proposed to implement different functions on common hardware, putting two or more network functions on standard hardware and reducing the number of devices purchased. The aim is to eliminate proprietary equipment that requires different skills to install, configure, test, and maintain, as well as reduce overall power and HVAC requirements.

Based on these demands, SD-WAN equipment vendors have proposed concepts such as VCPE (virtual CPE) and UCPE (general CPE), so that client devices can achieve standardized software construction and support multi-vendor and multi-price construction, so that client devices can be customized according to customer needs, and can support subsequent scalability, saving users a lot of investment in the early stage and realizing subsequent elastic expansion.

The specific implementation form of SD-WAN is intelligent networking, which can be plug-and-play, and the branch equipment is online with zero configuration, for example, we have a box and a data center address, and all your policy requirements are sent to the box.

Of course, you also have to do some equipment self-authentication, and you can't let other boxes connect to your network. On the simple side, you only need to do a basic verification and authorization of the device, register, and the cloud management platform will run on its own.

In this way, it solves the problems of many chain enterprise networking, and the biggest advantage of SD-WAN technology is high security and good stability. For chain enterprises, it also saves a lot of high costs for networking, which can be described as killing two birds with one stone.

The SD-WAN solution is implemented in the following ways:

1. Secure SD-WAN system

1) All data transmitted through the SD-WAN tunnel is encrypted by the AES 3DES encryption algorithm of 128-168 bits, which can effectively prevent data from being eavesdropped or tampered with.

2) Strict key authentication, only users who know the key can access it, to prevent illegal users from breaking in, the key is kept by the company's network management and can be changed at any time.

3) INAS digital certificate.

Technology, support PKI authentication system, bind SD-WAN user's computer hardware information (hard disk, CPU, network card, etc.), only user name.

Keys and user digital certificates can only be connected through authentication, and even if the user name and password are stolen, the SD-WAN network remains unbreakable.

4) Powerful intranet.

Management function, after the branch is connected to the headquarters LAN through SD-WAN, it can only access the intranet resources allocated by the headquarters administrator, and different branches can set different access rights to avoid malicious attacks by using the intranet and effectively ensure the security of the network.

Second, the speed is fast

SD-WAN uses kernel-driven technology and data flow.

The real-time compression algorithm (LZO) can make the bandwidth utilization rate as high as 90%, which is especially suitable for applications such as databases and file transfers. The maximum compression ratio of the file during the transfer process.

Up to 180%.

3. Efficient and stable SD-WAN system

SD-WAN supports full dynamic IP address networking, and supports various access methods, such as ADSL PSTN IP GPRS WLAN, etc., to ensure the stability of SD-WAN addressing and truly realize a private internal network.

SD-WAN (SDN): Software Defined Networking. By separating the control plane of network devices from the data plane, the flexible control of network traffic is realized, and the network becomes more intelligent as a pipe, providing a good platform for the innovation of core networks and applications.

The WAN of SD-WAN is a wide area network that covers a wider range than both local area networks (LANs) and metropolitan area networks (MAN). The communication subnet of the WAN can use the public packet switched network, the satellite communication network and the wireless packet switched network, which will interconnect the local area network or computer system distributed in different regions to achieve the purpose of resource sharing.

SD-WAN is a service formed by applying SDN technology to WAN scenarios based on MPLS-VPN and connecting enterprise networks, data centers, Internet applications and cloud services in a wide geographical range. Generally, the enterprise LAN or computer system distributed in different regions is interconnected in the form of virtual private network on the public network to achieve the purpose of resource sharing.

Dandelion Router is an intelligent networking solution developed based on SD-WAN technology, which supports software and hardware networking and realizes remote networking.

We do catering is a dandelion router, which supports software and hardware networking to achieve remote networking, which is also more convenient to manage.

Yes, SD-WAN is a commonly used enterprise networking solution. SD-WAN is a software-defined networking technology that can manage networks deployed in enterprise branch offices or in the cloud by virtualizing network functions.

The SD-WAN solution offers the following benefits:

Improve network bandwidth utilization and availability.

In addition to SD-WAN, there are other solutions for enterprise networking, such as:

VPN: A virtual private network (VPN) can provide a secure connection across the internet, making it easy to work remotely and access branch offices.

MPLS: Multiprotocol Label Switching (MPLS) is a technology for transferring data that can be used to connect branch offices to data centers.

VPC: A virtual private cloud (VPC) is a cloud computing solution that securely extends the connection between an enterprise data center and a cloud service provider to a cloud environment.

When choosing an enterprise networking solution, you need to evaluate the pros and cons of each option based on your specific business needs and budget.

Telstra Pacific is one of the first companies to pass the SD-WAN certification of the China Academy of Information and Communications Technology, and can provide complete SD-WAN solutions for enterprises. If you have networking needs, Liangfeng can learn about it.

If you use traditional networking to solve the problem of Fang Pai, you need to apply for a private network and a private line, and at the same time, the five locations also need to fix the public IP and the corresponding network server, which not only requires a lot of money costs, but also requires professional operation and maintenance personnel. The use of networking only requires the deployment of a communication router in various places, and then a simple setting in the cloud management background can realize multi-place interconnection and data interaction, and the whole process does not even require professional operation and maintenance personnel to participate.

First, the SDWAN solution is a network construction method based on software-defined networking (SDN) technology, while the traditional networking solution is a network construction method based on hardware devices. This means that the SDWAN solution focuses more on network construction through software, while the traditional networking solution focuses on network construction through hardware devices.

Second, the SDWAN solution is more flexible and can quickly adjust the network topology and traffic routing strategy according to service requirements. However, the traditional networking scheme is relatively fixed, and it is often necessary to modify the configuration of hardware devices to adjust the network topology and balance the traffic routing and bridge judgment strategy, which is more cumbersome to operate.

In addition, the SDWAN solution is more secure and can protect network traffic through built-in security mechanisms to avoid network attacks. However, traditional networking solutions often require additional security equipment to protect network traffic, and the security is relatively low.

In short, the SDWAN solution is more flexible, efficient, and secure than the traditional networking solution. It can provide enterprises with more stable, efficient, and reliable network connections, and meet their requirements for high performance, high capacity, high reliability, and high security.
