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.

This document is a product of the Common Control and Measurement Plane
Working Group of the IETF.  

This is now a Proposed Standard Protocol.

This document specifies an Internet standards track protocol for
the Internet community, and requests discussion and suggestions
for improvements.  Please refer to the current edition of the
"Internet Official Protocol Standards" (STD 1) for the
standardization state and status of this protocol.  Distribution
of this memo is unlimited.
