Abstract:
1. A first provider edge network element to be coupled with a customer edge network element over an attachment circuit and the first provider edge network element also to be coupled with a second provider edge network element over a packet-pseudowire over a tunnel in a Packet Switched Network (PSN), the first provider edge network element to reduce the size of protocol data units with IP (Internet Protocol) and MPLS (Multiprotocol Label Switching) packet payloads carried on the packet-pseudowire, the first provider edge network element comprising: a provider edge bound EIM (Efficient IP MPLS) module configured to receive frames transmitted from the customer edge network element over the attachment circuit, the provider edge bound EIM module including: a transmission module to transmit the protocol data units on the packet-pseudowire over the PSN tunnel to the second provider edge network element.
