Layer 2 services (such as Frame Relay, Asynchronous Transfer Mode, and
Ethernet) can be "emulated" over an MPLS backbone by encapsulating
the Layer 2 Protocol Data Units (PDU) and transmitting them over
"pseudowires".  It is also possible to use pseudowires to provide
low-rate Time Division Multiplexed and a Synchronous Optical
NETworking circuit emulation over an MPLS-enabled network.  This
document specifies a protocol for establishing and maintaining the
pseudowires, using extensions to Label Distribution Protocol (LDP).
Procedures for encapsulating Layer 2 PDUs are specified in a set of
companion documents.  [STANDARDS TRACK]

This document is a product of the Pseudo Wire Emulation Edge to Edge
Working Group of the IETF.

This is now a Proposed Standard Protocol.

STANDARDS TRACK: This document specifies an Internet standards track
protocol for the Internet community,and requests discussion and 
suggestions for improvements.Please refer to the current edition of 
the Internet Official Protocol Standards (STD 1) for the standardization 
state and status of this protocol.  Distribution of this memo is 
unlimited.
