How does SD WAN save network expenditure What are the main SD WAN manufacturers and service provider

SD-WAN technology can support multiple line access modes at the same time, such as ADSL GPON, metro private line, and even LTE. Users can flexibly choose according to their own environment and network application needs, reducing fixed network fees from the source.

At the same time, SD-WAN's intelligent cloud control center can adjust the link in real time to ensure the link quality and bandwidth requirements of different applications. In this way, SD-WAN technology can accurately select the access mode while maintaining the quality of the network and link. At present, SD-WAN product manufacturers can be divided into foreign brands and domestic brands.

Foreign brands mainly include Aryaka, Riverbed, Cisco, Velocloud and other brands; The main ones in China are Huawei and Xinhua.

Third, the earth cloud network, etc., each factory has its own focus, but the leading one is undoubtedly Huawei. Recently, a number of news and publicity have seen that Fnetlink Group is one of the priority partners of Huawei's SD-WAN products, and the earliest operation and maintenance service provider responsible for the implementation of Huawei's SD-WAN has successfully deployed SD-WAN for many large and medium-sized enterprises in China, and has also accumulated rich experience in technology and operation and maintenance support. You can try to understand, and we are also planning to understand this type of solution in depth and optimize the company's WAN architecture.

SD-WAN allows enterprises to intelligently aggregate overall bandwidth by path or application preference. Get bandwidth at a much lower cost. SD-WAN solutions can perform link aggregation at the same time, regardless of the type of connection.

This means that you can choose a cheaper connection option for low-priority traffic and a more expensive connection option for high-priority traffic.

SD-WAN is now divided into three major schools according to domestic manufacturers and international manufacturers:

First, software dominant. Mainly software-based products;

Second, the line is dominant. International networking, international dynamic transmission, and dynamic acceleration are all line-led;

Third, equipment is dominant.

The biggest advantage of SD-WAN and the reason why many companies turn to it is cost.

The expansion of MPLS and private line networks has become extremely expensive for companies looking to save money.

SD-WAN can be managed from ** locations via an application, unlike MPLS circuits that must be managed at each specific site. SD-WAN is also capable of supporting the cloud.

Although the SD-WAN Department has many advantages, it is impossible to achieve perfection. The most common problem with SD-WAN is that it has no security features because it is entirely Internet-based, which means that IT professionals not only have to manage the network, but also keep it safe from attacks, as one attack can disrupt the entire network. That's why many companies are turning to hybrid SD-WAN that combines SD-WAN with MPLS to give you the "best of both worlds".

SD-WAN is a software-based networking solution that helps businesses achieve more efficient, secure, and reliable network connectivity. The following is a summary of the values and benefits of the SD-WAN solution:

Improve network performance and reliability

SD-WAN can improve network performance and reliability in a number of ways. First, it can use multiple network connections (such as internet, MPLS, 4G, etc.) for load balancing and failover. This means that even if one network connection fails, the business can still maintain the network connection.

Second, SD-WAN can improve network performance using intelligent routing and application optimization. These features ensure that network traffic always travels through the optimal path and optimize the performance of your applications.

Improve network security

SD-WAN can improve network security because it can protect corporate networks using a variety of security features. For example, SD-WAN can use encryption to protect data transmissions and prevent data breaches. It can also use features such as firewalls, intrusion detection, and prevention to protect corporate networks from cyberattacks and malware.

Reduce network costs

SD-WAN can reduce enterprise network costs because it can use multiple network connections for load balancing and failover. This means that businesses can use a cheaper internet connection instead of an expensive MPLS connection, reducing network costs. In addition, SD-WAN can reduce enterprise IT spending by reducing network failures and improving network performance.

SD-WAN solutions are already widely used in many enterprises. Here are some examples of how to use them in action:

Retail businesses

Some retail businesses use SD-WAN to connect their stores and warehouses across the country. SD-WAN can help these enterprises achieve more efficient and reliable network connectivity and improve network security. In addition, SD-WAN can reduce network costs because it can replace expensive MPLS connections with cheaper internet connections.

Healthcare Businesses

Some healthcare businesses use SD-WAN to connect their hospitals and clinics. SD-WAN can help these enterprises achieve more efficient and reliable network connectivity and improve network security. In addition, SD-WAN can improve network performance using intelligent routing and application optimization, thereby improving the quality of healthcare services.

Financial enterprises

Some financial enterprises use SD-WAN to connect their branches and data centers. SD-WAN can help these enterprises achieve more efficient and reliable network connectivity and improve network security. In addition, SD-WAN can enable the cavity sail to protect data transmission with encryption and prevent data leakage.

SD-WAN builds a WAN that is open, flexible, and easy to O&M for enterprise users.

Users can autonomously control the flow direction of WAN traffic according to predetermined blind bend routing policies, helping users reduce WAN (WAN) expenses and improve connection flexibility.

Typical application scenarios of SD-WAN include hybrid WAN scenarios, cloud access scenarios, and mobile office scenarios.

By introducing the SD-WAN controller, the centralized management and automatic configuration of the access devices of each branch of the enterprise can be completed, and each branch of the enterprise can be flexibly connected to the public cloud or private cloud.

Provide users with visualized and configurable network topology and traffic monitoring, and provide enterprises with cloud-based value-added services such as security protection.

The SD-WAN solution, based on virtualized enterprise gateway products and cloud-based service deployment, provides flexible, intelligent, customized, automated, and differentiated intelligent private line and cloud private line services for government and enterprise customers, and is suitable for different application scenarios such as site-site, site-internet, and site-IDC. It has the characteristics of agile provisioning, international acceleration, hybrid networking, and cloud-network synergy.

SD-WAN solutions include enterprise gateways, SD-WAN controllers, collaborative orchestrators, and business-oriented portals. Among them, the enterprise gateway is based on the x86 architecture.

White-box machine deployment, general-purpose server-based metal bare metal deployment, and cloud-based virtual host.

The three deployment forms have the characteristics of high performance, flexible ministry, and elastic scaling, and meet the business needs of enterprise customers in scenarios such as cloud private line, virtualization, and Internet of Things.

We are accelerating the R&D and implementation of SD-WAN to promote the market application of next-generation enterprise private line technology and emerging products, and contribute to the development of the SD-WAN industry.

SD-WAN is actually SDN+WAN and is an important branch of SDN-based applications. What is SDN? SDN is an abbreviation for Software DefinedNetwork.

Compared with SDN, SD-WAN focuses on WAN (Wide Area Network), so SD-WAN is a software-defined wide area network (WAN), which is a service that applies SDN technology to WAN scenarios.

In layman's terms, SD-WAN is a service that redefines a larger geographic scope, such as cross-city, inter-provincial, or even cross-border WAN, through software integration. Nowadays, it is widely used in cloud office and network integration between branches and between branches and head offices. For example, many large chain organizations have branches in many provinces, cities and even multinational countries, as well as a huge network of branches.

In this case, the network of each branch can be regarded as a local area network, but the headquarters wants to ensure the experience of cloud office and have a certain security guarantee in the case of realizing a unified online cloud office, so it is necessary to integrate and manage the LAN of each branch and the network site of each branch, at this time, the SD-WAN networking solution comes in handy.

At present, there are many domestic SD-WAN service providers, such as China Telecom, China Unicom, China Mobile, etc., which can also provide networking services, but they basically provide networking services based on this network product, and customers have great limitations in network selection. What most enterprises need is not a simple SD-WAN networking service, but a comprehensive, complete and advanced SD-WAN networking solution based on the network characteristics of different regions and office needs.

In the field of SD-WAN networking solutions should do a better job Fnetlink Group, taking the SD-WAN networking solution provided by Fnetlink Group as an example, based on the strategic cooperation with Huawei, Fnetlink Group's SD-WAN networking solution is arranged on Huawei Cloud, so that users can see the layout work very intuitively, if the customer itself has Huawei land, you can join the SD-WAN network by upgrading. Its significance lies not only in helping enterprises complete WAN networking, but also in providing the best experience, best cost, and simplest O&M networking scheme according to the office characteristics of the enterprise and the original network characteristics.

Answer: 1. SD-WAN, that is, software-defined WAN, is a service formed by applying SDN technology to WAN scenarios, which is used to connect enterprise networks, data centers, Internet applications and cloud services in a wide geographical range. It is characterized by the cloudification of network control capabilities through software, which supports the exposure of application-aware network capabilities.

2. SD-WAN represents the most interesting application of SDN technology in 2015, which is designed to help users reduce the cost of wide area network (WAN) and improve the flexibility of network connection. According to a survey, although there are a large number of new and old first-class merchants entering the market, the actual deployment in 2015 is still very limited. But SD-WAN is far from just a buzzword, it's already benefiting early adopters.
