What does sdwan mean?

Sdwan means: SD-wan, a software-defined wide area network, is a service formed by applying SDN technology to WAN scenarios. This service is used to connect enterprise networks, data centers, Internet applications and cloud services in a wide geographical range. The typical feature of this service is that the network control ability is' cloud-based' through software, and the network ability supporting application awareness is open.

SD-WAN represents the most attractive application of SDN technology in 20 15. It aims to help users reduce the cost of WAN and improve the flexibility of network connection. According to a survey, although many new and old suppliers have entered the market, the actual deployment of 20 15 shows that the real landing projects are still very limited. But SD-WAN is not just a buzzword, it has brought benefits to early deployers. ?

From the centralized control architecture and Openflow protocol proposed by Stanford University in 2006 to the business case of Google B4 in 20 12, the focus of SDN germination and disillusionment has been on the scene of cloud and data center, and the industry urgently needs to find the next killer app.

On the other hand, the development of cloud computing technology has triggered changes in the IT industry, and internet plus has promoted changes in traditional industries. The internetization of to B surpassed the attention of to C on 20 14. It can be said that SD-WAN service focusing on enterprise market and wide area network is formed under this industry background and expectation.
