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

摘要

embodiment of the invention provides a method and system for realizing a virtual private network, based on traffic engineering tunnel. Virtual private network implemented method based on traffic engineering tunnel includes the steps of establishing a traffic engineering tunnel established in response to the information regarding the virtual private network service; Wherein the (bear) phase responsible for a virtual private network service using the traffic engineering tunnel; And in response to the clear information about the virtual private network service comprises the step of deleting the traffic engineering tunnel. In this manner, a dynamically established or deleted according to the requirements of traffic engineering tunnel virtual private network service and, if necessary, provide a mechanism for establishing a TE tunnel, and the tunnel is not used promptly by the virtual private network service Since deleting, and saving network resources effectively. ;
