Title : Requirements for GMPLS-based multi-region and multi-layer networks (MRN/MLN)

Most of the initial efforts to utilize Generalized MPLS (GMPLS) have been
related to environments hosting devices with a single switching capability. The
complexity raised by the control of such data planes is similar to that seen in
classical IP/MPLS networks.
By extending MPLS to support multiple switching technologies, GMPLS provides a
comprehensive framework for the control of a multi-layered network of either a
single switching technology or multiple switching technologies.
In GMPLS, a switching technology domain defines a region, and a network of
multiple switching types is referred to in this document as a Multi-Region
Network (MRN). When referring in general to a layered network, which may consist
of either a single or multiple regions, this document uses the term, Multi-Layer
Network (MLN). This document defines a framework for GMPLS based multi-
region/multi-layer networks and lists a set of functional requirements.

In the body type:
"FILE /internet-drafts/draft-ietf-ccamp-gmpls-mln-reqs-04.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.
Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
Internet-Draft.
