The suite of protocols that defines Multi-Protocol Label Switching
(MPLS) is in the process of enhancement to generalize its
applicability to the control of non-packet based switching, that is,
optical switching. One area of prime consideration is to use these
generalized MPLS (GMPLS) protocols in upgrading the control plane of
optical transport networks. This document illustrates this process
by describing those extensions to MPLS protocols that are directed
towards controlling SONET/SDH networks. SONET/SDH networks make
very good examples of this process since they possess a rich
multiplex structure, a variety of protection/restoration options,
are well defined, and are widely deployed. The document discusses
extensions to MPLS routing protocols to disseminate information
needed in transport path computation and network operations,
together with the extensions to MPLS label distribution protocols
needed for the provisioning of transport circuits. New capabilities
that an MPLS control plane would bring to SONET/SDH networks, such
as new restoration methods and multi-layer circuit establishment,
are also discussed.

MIME-encoded form by using the "mpack" utility. To use this
feature, insert the command "ENCODING mime" before the "FILE"

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.
