Encapsulation Methods for Transport of Ethernet over MPLS Networks
RFC 4448, “Encapsulation Methods for Transport of Ethernet over MPLS Networks”, is a Proposed Standard document published in April 2006 by L. Martini, E. Rosen, N. El-Aawar, G. Heron. It has since been updated by RFC 5462, RFC 8469. The canonical text is published by the RFC Editor.
Abstract
An Ethernet pseudowire (PW) is used to carry Ethernet/802.3 Protocol Data Units (PDUs) over an MPLS network. This enables service providers to offer "emulated" Ethernet services over existing MPLS networks. This document specifies the encapsulation of Ethernet/802.3 PDUs within a pseudowire. It also specifies the procedures for using a PW to provide a "point-to-point Ethernet" service. [STANDARDS-TRACK]
What “Proposed Standard” means
An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
