Synchronous Optical Network/Synchronous Digital Hierarchy (SONET/SDH) Circuit Emulation Service over MPLS (CEM) Encapsulation
RFC 5143

Approval announcement
Draft of message to be sent after approval:

From: The IESG <iesg-secretary@ietf.org>
To: RFC Editor <rfc-editor@rfc-editor.org>

Subject: Re: Historic to be: draft-malis-sonet-ces-mpls-10.txt 

The IESG has no problem with the publication of 'SONET/SDH Circuit 
Emulation Service over MPLS (CEM) Encapsulation' 
<draft-malis-sonet-ces-mpls-10.txt> as a Historic. 

The IESG would also like the IRSG or RFC-Editor to review the comments in 
the datatracker 
(https://datatracker.ietf.org/public/pidtracker.cgi?command=view_id&dTag=5608&rfc_flag=0) 
related to this document and determine whether or not they merit 
incorporation into the document. Comments may exist in both the ballot 
and the comment log. 

The IESG contact person is Mark Townsley.

The process for such documents is described at http://www.rfc-editor.org/indsubs.html.

Thank you,

The IESG Secretary

Technical Summary
 
 This document describes a historical method for encapsulating 
  SONET/SDH Path signals for transport across packet-switched networks 
  (PSNs).  The PSNs explicitly supported by this document include MPLS 
  and IP. Note that [RFC4842] describes the standards-track protocol  
  for this functionality, and new implementations must use [RFC4842] 
  rather than this document except when interoperability with older  
  implementations is desired.  

Working Group Summary
 
This documents contains work that was the basis of part of the
PWE3 WG's efforts, resulting in the publication of RFC4842 as
a standards track document. The document was specifically held 
from publication in any form until which time the PWE3 WG had finished
its work in this area.

Deployed implementations of this earlier work exist, though it is well 
understood the output of the PWE3 WG represents IETF Consensus and 
supersedes these mechansims. This document is now being published 
for the record as Historic to underscore that it documents work that has 
been obsoleted by PWE3 Standards Track work.
 
Protocol Quality
 
This specification was reviewed for the IESG by Mark Townsley. It has been
reported that there
are deployed implementations of this, though there is commitment to move
to standards
track work in due course.

IESG Note:


  2. The IESG thinks that this work is related to IETF work done in WG
     PWE3, but this does not prevent publishing.
