Ballot Text

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.
