摘要： An architecture for providing service mediation in a network having a Layer-2 domain and an MPLS domain includes at least one Layer-2 provider edge device in communication with a first customer site; at least one Layer-2 edge device in communication with the Layer-2 provider edge device; at least one MPLS mediation edge device in communication with the Layer-2 edge device; and at least one MPLS provider edge device in communication with both the MPLS mediation edge device and a second customer site. An end-to-end connection is established using native Layer-2 signaling, if any, in the Layer-2 domain and PWE3 signaling protocols in the MPLS domain. The MPLS mediation edge device resolves associations between Layer-2 edge devices and MPLS provider edge devices. The service is “mediated” in the sense that native Layer-2 signaling is terminated at the MME, and a new domain, i.e., pseudowire, is established across the MPLS domain.

摘要： The present invention provides a technique for automatically establishing a virtual circuit from one edge device to another through a core network. The virtual circuit may comprise one or more pseudowire segments. These pseudowire segments extend between adjacent edge and core devices within the core network. Pseudowire segments through the core network are automatically stitched together as a setup message is forwarded from a first edge device to a second edge device through the core network. A virtual circuit is established in one direction, and packets are forwarded in an opposite direction. With the present invention, a virtual circuit comprising any number of pseudowire segments, as well as two attachment circuits, may be established in an automatic and efficient manner upon being initiated by the first edge device.
