APPARATUS AND METHOD FOR PSEUDO WIRE EMULATION EDGE-TO-EDGE ACCESS

摘要

The present invention discloses a device for decision-circuit emulation edge-to-edge connections. In addition, the present invention is disclosed a method for decision-circuit emulation edge-to-edge connection, the method comprising the local service providers peripheral (PE) receives a non-Ethernet data originated by a local user to a doctor, and then the inner layer circuit emulation edge-to-edge (PWE3) executes the encapsulated in the frame format, the outer capsule 2 layer virtual private network (L2VPN) for the simulation data frame format as the encapsulation step of the calling and the encapsulation of the data in the peer PE; And after receiving the data from the other party is a local PE PE, outer layer and frame formats as L2VPN Run the decapsulation and inner PWE3 frame format with the decapsulation, and then the non-local Ethernet data obtained through decapsulation to double a step of sending to the user. The present invention is to realize a pseudo-circuit emulation edge-to-edge for a non-Ethernet connection in the context of the PE label space saving, pseudowires (PW) can be avoided that the label to be exchanged several times. ;
