I-D ACTION:draft-ietf-mpls-vcid-atm-01.txt



A New Internet-Draft is available from the on-line Internet-Drafts directories.
This draft is a work item of the Multiprotocol Label Switching Working Group 
of the IETF.

	Title		: VCID Notification over ATM link
	Author(s)	: N. Demizu, H. Esaki, K. Nagami, P. Doolan
	Filename	: draft-ietf-mpls-vcid-atm-01.txt
	Pages		: 11
	Date		: 04-Aug-98
	
   The ATM Label Switching Router (ATM-LSR) is one of the major
   applications of label switching. Because the ATM layer labels (VPI
   and VCI) associated with a VC may change on each VC of that VC, it is
   not possible to use them to identify a VC in label binding
   messages. The concept of Virtual Connection Identifier (VCID) is
   introduced to solve this problem.  VCID has the same value at both
   ends of a VC.  This document specifies the procedures for the
   communication of VCID values between neighboring ATM-LSRs that must
   occur in order to ensure this property.

Send a message to:	mailserv at ietf.org.  In the body type:
	"FILE /internet-drafts/draft-ietf-mpls-vcid-atm-01.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.
