Abstract:
1. A communications network comprising: an Ethernet packet-switched network (PSN); a first provider edge (PE) device in communication with a second PE device through the Ethernet PSN; a pseudowire (PW) established between the PE devices for emulating a service across the Ethernet PSN, each packet of the service having a frame format with an Ethernet tunnel header and a PW header that encapsulates a payload; and a Multi-Protocol Label Switching (MPLS) network in communication with the Ethernet PSN, wherein the PW extends through the MPLS network and the Ethernet PSN, and wherein each packet is forwarded through the MPLS network after removing the Ethernet tunnel header from the packet and adding a Multi-Protocol Label Switching (MPLS) tunnel header to the packet.
