A New Internet-Draft is available from the on-line Internet-Drafts 
directories.
This draft is a work item of the Common Control and Measurement Plane Working Group of the IETF.

	Title		: A Per-domain path computation method for establishing Inter-domain Traffic Engineering (TE) Label Switched Paths (LSPs)
	Author(s)	: J. Vasseur, et al.

This document specifies a per-domain path computation technique for
   establishing inter-domain Traffic Engineering (TE) Multiprotocol
   Label Switching (MPLS) and Generalized MPLS (GMPLS) Label Switched
   Paths (LSPs).  In this document a domain refers to a collection of
   network elements within a common sphere of address management or path
   computational responsibility such as IGP areas and Autonomous
   Systems.

   Per-domain computation applies where the full path of an inter-domain
   TE LSP cannot be or is not determined at the ingress node of the TE
   LSP, and is not signaled across domain boundaries.  This is most
   likely to arise owing to TE visibility limitations.  The signaling
   message indicates the destination and nodes up to the next domain
   boundary.  It may also indicate further domain boundaries or domain
   identifiers.  The path through each domain, possibly including the
   choice of exit point from the domain, must be determined within
   the domain.

Send a message to:

In the body type:
	"FILE /internet-drafts/draft-ietf-ccamp-inter-domain-pd-path-comp-05.txt".
	
NOTE:	The mail server at ietf.org can return the document in
	MIME-encoded form by using the "mpack" utility.  To use this
	feature, insert the command "ENCODING mime" before the "FILE"
	command.  To decode the response(s), you will need "munpack" or
	a MIME-compliant mail reader.  Different MIME-compliant mail readers
	exhibit different behavior, especially when dealing with
	"multipart" MIME messages (i.e. documents which have been split
	up into multiple messages), so check your local documentation on
	how to manipulate these messages.

Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
Internet-Draft.
