System and method for realizing static routing tunnel based on SDN

Abstract

The invention relates to the field of virtual networks, and discloses a system for realizing a static routing tunnel based on an SDN. The system comprises a plurality of forwarders and an SDN controller, and the plurality of forwarders are respectively deployed in data centers of regions of an operator; the SDN controller controls a forwarder on a link between a data transmission location and a data destination of user data in user data transmission service, and establishes an overlay tunnel passing by the forwarder on the link between the data transmission location and the data destination. The invention further discloses a method for realizing the static routing tunnel based on the SDN. By adoption of the system and method provided by the invention, the construction of the virtual networks and the data transmission can be accelerated.

Description

technical field [0001] The invention relates to the field of virtual networks, in particular to a system for realizing static routing tunnels based on SDN and a method for realizing static routing tunnels based on SDN. Background technique [0002] For large enterprises, branches of the enterprise are often located in different regions. In today's information age, virtual private lines need to be flexibly established between branches to facilitate communication and information transmission between branches. [0003] For the traditional way of establishing a virtual private network, it is not easy for an enterprise to create and deploy a virtual private network, and the network of the virtual private network needs to be carefully planned and configured, which leads to a long period of business development of the virtual private network. At the same time, the traditional virtual private network lacks flexibility and cannot establish different virtual private networks for diffe...

[0003] For the traditional way of establishing a virtual private network, it is not easy for enterprises to create and deploy a virtual private network, and the network of the virtual private network needs to be carefully planned and configured, which leads to a long period of business development of the virtual private network

At the same time, the traditional virtual private network lacks flexibility and cannot establish different virtual private networks for different departments within the enterprise, and the traditional virtual private network cannot freely plan routes on the wide area network and cannot provide cross-communication carrier-level communication channels
