I-D ACTION:draft-ietf-ccamp-gmpls-architecture-06.txt



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		: Generalized Multi-Protocol Label Switching 
                          Architecture
	Author(s)	: E. Mannie
	Filename	: draft-ietf-ccamp-gmpls-architecture-06.txt
	Pages		: 57

Future data and transmission networks will consist of elements such
as routers, switches, Dense Wavelength Division Multiplexing (DWDM)
systems, Add-Drop Multiplexors (ADMs), photonic cross-connects
(PXCs), optical cross-connects (OXCs), etc. that will use
Generalized Multi-Protocol Label Switching (GMPLS) to dynamically
provision resources and to provide network survivability using
protection and restoration techniques.
This document describes the architecture of GMPLS. GMPLS extends
MPLS to encompass time-division (e.g. SONET/SDH, PDH, G.709),
wavelength (lambdas), and spatial switching (e.g. incoming port or
fiber to outgoing port or fiber). The focus of GMPLS is on the
control plane of these various layers since each of them can use
physically diverse data or forwarding planes. The intention is to
cover both the signaling and the routing part of that control plane.

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.
