Technical Summary The PWE3 WG is defining mechanisms for carrying lower-layer protocols (e.g., L2) over IP and MPLS networks and emulating the services they provide. This document defines the requirements for edge-to-edge-emulation of circuits carrying Time Division Multiplexed digital (TDM) signals of the Plesiochronous Digital Hierarchy (PDH) as well as the Synchronous Optical NETwork (SONET)/Synchronous Digital Hierarchy (SDH) over packet-switched networks. The requriments are aligned to the common architecture for PWE3. It makes references to the generic requirements for PWE3 where applicable and complements them by defining requirements originating from specifics of TDM circuits. Working Group Summary There was concensus for this document in the WG. Protocol Quality This document has been reviewed for the IESG by Thomas Narten.
