VIRTUAL PRIVATE NETWORK IMPLEMENTATION METHOD AND SYSTEM BASED ON TRAFFIC ENGINEERING TUNNEL

摘要

Embodiments of the present invention provide a virtual private network implementation method and system based on a traffic engineering tunnel. The virtual private network implementation method based on a traffic engineering tunnel includes: establishing a traffic engineering tunnel in response to establishment information about a virtual private network service; bearing the virtual private network service using the traffic engineering tunnel; and deleting the traffic engineering tunnel in response to cancellation information about the virtual private network service. In the foregoing manner, a traffic engineering tunnel is dynamically established or deleted according to a requirement of a virtual private network service, a mechanism for establishing a TE tunnel as required is provided, and the tunnel not used by the virtual private network service is deleted in time, thereby effectively saving network resources.
