Encapsulation Methods for Transport of Ethernet Frames Over IP and MPLS Networks

Encapsulation Methods for Transport of Ethernet Frames Over IP and MPLS Networks An Ethernet PW allows Ethernet/802.3 Protocol Data Units (PDUs) to be carried over Packet Switched Networks (PSNs) using IP, L2TP or MPLS transport. This enables Service Providers to leverage their existing PSN to offer Ethernet services. This document describes methods for encapsulating Ethernet/802.3 PDUs for transport over an MPLS or IP network.
