Body:
The CCAMP Working Group of the IETF wishes to inform Study Group 15 of
the ITU-T of the publication of a new Request for Comment.

RFC 4139 "Requirements for Generalized MPLS (GMPLS) Signaling Usage and
Extensions for Automatically Switched Optical Network (ASON)" is
available at http://www.ietf.org/rfc/rfc4139.txt

The Abstract of this RFC reads as follows.

   The Generalized Multi-Protocol Label Switching 
   (GMPLS) suite of protocols has been defined to 
   control different switching technologies and 
   different applications.  These include support for 
   requesting Time Division Multiplexing (TDM) 
   connections, including Synchronous Optical Network 
   (SONET)/Synchronous Digital Hierarchy (SDH) and 
   Optical Transport Networks (OTNs).

   This document concentrates on the signaling aspects 
   of the GMPLS suite of protocols.  It identifies the 
   features to be covered by the GMPLS signaling 
   protocol to support the capabilities of an 
   Automatically Switched Optical Network (ASON). This 
   document provides a problem statement and additional 
   requirements for the GMPLS signaling protocol to 
   support the ASON functionality.

The CCAMP Working Group would like to thank the members and Questions
of Study Group 15 for the helpful input and review feedback that they
provided while this document was being developed.

The CCAMP Working Group continues to actively pursue protocol solutions
for the ASON model and seeks to harmonise GMPLS and ASON. We will keep
you informed of our future progress.
