Technical Summary
This document specifies the mapping and notification of defect states
between a pseudowire (PW) and the Attachment Circuits (ACs) of the
end-to-end emulated service. It standardizes the behavior of Provider
Edges (PEs) with respect to PW and AC defects. It addresses ATM, Frame
Relay, TDM, and SONET/SDH PW services, carried over MPLS, MPLS/IP and
L2TPV3/IP Packet Switched Networks (PSNs).
Working Group Summary
One of the work items in the PWE3 Working Group Charter is to "Specify
Operations and Management (OAM) mechanisms for all PW types, suitable for
operation over both IP/L2TPv3 and MPLS PSNs, and capable of providing the
necessary interworking with the OAM mechanisms of the emulated service."
This document addresses this work item for ATM, Frame Relay, TDM, and
SONET/SDH pseudowires. A separate document will address Ethernet
pseudowires.
Document Quality
