Title : Framework for GMPLS-based Control of SDH/SONET Networks
Author(s) : G. Bernstein, et al.
Filename : draft-ietf-ccamp-sdhsonet-control-05.txt
Pages : 31
Date : 2005-2-23
Generalized MPLS (GMPLS) is a suite of protocol extensions to MPLS
(Multi-Protocol Label Switching) to make it generally applicable, to
include - for example - control of non packet-based switching, and
particularly, optical switching. One consideration is to use GMPLS
protocols to upgrade the control plane of optical transport networks.
This document illustrates this process by describing those extensions
to GMPLS protocols that are aimed at controlling Synchronous Digital
Hierarchy (SDH) or Synchronous Optical Networking (SONET) networks.
SDH/SONET networks make good examples of this process for a variety
of reasons. This document high-lights extensions to GMPLS-related
routing protocols to disseminate information needed in transport path
computation and network operations, together with (G)MPLS protocol
extensions required for the provisioning of transport circuits. New
capabilities that an GMPLS control plane would bring to SDH/SONET
networks, such as new restoration methods and multi-layer circuit
establishment, are also discussed.

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.
