Problems solved by technology

[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

Embodiment Construction

[0035] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0036] see figure 1 As shown, the present invention provides a system based on SDN (Software Defined Network, software-defined network) to realize static routing tunnels, which is used to construct a virtual private network to meet the transmission of user data between users in various branches of an enterprise, or a certain transmission of user data between specific users. The system includes an SDN controller and multiple transponders. The SDN controller is deployed in the computer room of the communication operator, and the transponder is deployed in the data center of each communication operator in each region. Of course, the transponder can also be deployed in foreign communication operators. Because communication operators will set up data centers in different regions, they adopt the method of arranging transponders in data centers, which corresponds t...

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...
