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 (PDUs) and then
transmitting them over pseudowires (PWs).  It is also possible to use
pseudowires to provide low-rate Time-Division Multiplexed and
Synchronous Optical NETworking circuit emulation over an MPLS-enabled
network.  This document specifies a protocol for establishing and
maintaining the pseudowires, using extensions to the Label
Distribution Protocol (LDP).  Procedures for encapsulating Layer 2
PDUs are specified in other documents.

This document is a rewrite of RFC 4447 for publication as an
Internet Standard.

This document is a product of the Pseudowire And LDP-enabled Services Working Group of the IETF.

This is now an Internet Standard.

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 Official
Internet Protocol Standards ( for the 
standardization state and status of this protocol.  Distribution of this 
memo is unlimited.
