Problems solved by technology

[0005] This communication method needs to build and configure a high-performance server at the headquarters. If there are a large number of clients, such as in application scenarios such as chain supermarket stores, the pressure on the server is very high, and there is a bottleneck in the number of connectable clients. question
In addition, because the traditional IPSec VPN is built on the Internet, it is difficult to control the quality of the network. When the Internet is congested, the IPSec VPN will also cause congestion.

Embodiment Construction

[0046] In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. However, the present invention can be implemented in many other ways different from those described here, and those skilled in the art can make similar extensions without violating the connotation of the present invention, so the present invention is not limited by the specific implementations disclosed below.

[0047] For the problems existing in traditional IPSec VPN, the embodiment of the present invention provides a SD-WAN (Software-Defined Wide Area Network, software-defined wide area network) network architecture, such as image 3 Shown is a schematic diagram of the network architecture.

[0048] The network architecture includes: multiple servers connected via the Internet, and a controller connected to each server. The controller is used for generating tunnel configuration information between different servers, and sending...

Abstract

The invention discloses an SD-WAN network architecture which comprises a plurality of servers which are connected through the Internet, and a controller which is connected with each server. The controller is used for generating tunnel configuration information between different servers and issuing the tunnel configuration information to each server. The invention also discloses an SD-WAN networking method and a message forwarding method based on SD-WAN network. By utilizing the method and the device, the free access of the client can be realized, the bottleneck problem of the access quantity of the client is avoided, and the reliability of the network is improved.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to an SD-WAN network architecture and a networking method, and also relates to a message forwarding method based on the SD-WAN network. Background technique [0002] VPN (Virtual Private Network, virtual private network), as a mature technology, is widely used in the networking and interconnection between the organization's headquarters and branches. The branches and the headquarters are connected to form a large local area network. In order to provide data encryption, authentication, and data tamper-proof functions, an IPSEC (Internet Protocol Security, Internet Protocol Security) protocol is introduced. [0003] IPsec is a security standard framework defined by IETF (Internet Engineering Task Force, Internet Engineering Task Force). It ensures confidential and secure communication on IP networks by using encrypted security services. It provides end-to-end public an...
