摘要
The present invention provides systems and methods which create an infrastructure/transport Pseudowire (PW) a priori between two Provider Edge (PE) devices. Accordingly, other PWs can be mapped to this transport PW. In an exemplary application, the transport PW (which is a MS-PW by itself) can start and end between two Switching Provider Edge (S-PE) devices and span across multiple S-PEs in between. In another exemplary application, the transport PW terminates between two Terminating Provider Edge (T-PE) devices spanning across all S-PEs in between. In a further exemplary application, the transport PW can start at a S-PE or T-PE and terminate at a T-PE or S-PE, respectively. The placement of the endpoints of the transport PW (on two PEs) determines the number of intervening S-PEs that benefit from this application.
