Problems solved by technology

In this solution, the establishment of the TE tunnel is separated from the VPN service, and there are cases where the established TE tunnel is not used by the VPN service, thus causing a waste of network resources
[0005] In summary, it is necessary to provide a VPN implementation method and system based on TE tunnels to solve the problem of waste of network resources caused by the separation of TE tunnel establishment and VPN services in existing VPN implementation solutions

Embodiment Construction

[0020] See figure 1 , figure 1 It is a flowchart of a method for implementing a VPN based on a TE tunnel according to an embodiment of the present invention. Such as figure 1 As shown, the TE tunnel-based VPN implementation method of this embodiment mainly includes the following steps:

[0021] Step 101: Create a TE tunnel in response to the establishment information of the VPN service;

[0022] Step 102: use the TE tunnel to carry the VPN service; and

[0023] Step 103: Delete the TE tunnel in response to the revocation information of the VPN service.

[0024] Through the above method, the TE tunnel-based VPN implementation method of this embodiment dynamically creates or deletes TE tunnels according to the needs of VPN services, provides a mechanism for creating TE tunnels on demand, and deletes tunnels that are not used by VPN services in time, Effectively save network resources.

[0025] See figure 2 , figure 2 It is a schematic diagram of the network structure o...

Abstract

The embodiment of the invention provides a traffic engineering tunnel-based virtual private network implementation method and a traffic engineering tunnel-based virtual private network implementation system. The traffic engineering tunnel-based virtual private network implementation method includes the following steps: responding to the establishment information of virtual private network service to create a traffic engineering tunnel; utilizing the traffic engineering tunnel to carry the virtual private network service; and responding to the cancel information of the virtual private network service to delete the traffic engineering tunnel. By means of the mode of dynamically creating or deleting the traffic engineering tunnel according to the demand of the virtual private network service, the invention provides a mechanism for creating the traffic engineering tunnel on demand, and timely deletes the tunnel which is not used by the virtual private network service, thus effectively saving network resources.

Description

technical field [0001] The present invention relates to the technical field of virtual private network, in particular to a virtual private network realization method and system based on traffic engineering tunnel. Background technique [0002] With the increasing popularity of the network, in order to share business data among various branches of the company, it is necessary to connect each branch to the Internet to share data under the premise of ensuring data storage and transmission security. In order to achieve this purpose, in addition to renting dedicated lines to realize interconnection among branches, a virtual private network (Virtual Private Network, VPN) can also be established directly through the public network. VPN utilizes the public network and virtualizes the public network into a private network through means such as tunnel technology, so as to realize secure data transmission similar to a private private network. [0003] VPN services can be carried by Tr...
