Method and system for end-to-end pseudo-line simulation virtual leased line access virtual special network

Abstract

A method for switching end to end pseudoline artificial virtual leased line in to virtual special network includes setting multiple global unique pseudoline ID in virtual exchange example according to pseudoline ID of end to end psudoline artificial virtual leased line requiring to be switched-in, obtaining pseudoline ID corresponding to said virtual exchange example by end to end pseudoline artificial virtual leased line through matching and seeking then switching in said virtual exchange example. The system used for realizing said method is also disclosed.

Description

Method and system for end-to-end pseudowire emulation virtual leased line access virtual private network technical field The invention relates to the field of virtual private network, in particular to a method and system for end-to-end pseudowire emulation virtual leased line accessing virtual private LAN service. Background technique Initially, telecom operators provided links to customers in the form of Leased Line (Leased Line). However, as the number of customer branches increases, the cost of this method increases significantly, and the difficulty of management also increases. With the emergence of ATM (Asynchronize Transport Mode, Asynchronous Transfer Mode) and FR (Frame Relay, Frame Relay) technologies, telecom operators began to use virtual circuits to provide customers with point-to-point Layer 2 links, and customers then build their own The three-layer network carries IP (Internet Protocol, Internet Protocol) and other data streams. However, this technology pr...
