MPLS over GMPLS-based optical networks (MPLS over GMPLS) is a subset
of IP over optical networks. To be more specific, in this draft it
refers to the technology of interconnection between MPLS networks and
GMPLS-based optical networks with an overlay model or an interdomain
model. It is an important milestone in the evolutionary roadmap from
IP over static WDM to a peer model of network interconnections. The
most significant feature of the requirements for MPLS over GMPLS is a
much more dynamic interface between the two layers. The draft
discusses the evolutionary roadmap of IP over optical networks and
then highlights the significance of the concept of MPLS over GMPLS.
Some new requirements will be identified, including multi-lightpath
connections, MPLS network topology dynamic changes and dynamic
traffic grooming and so on. It is these requirements that bring some
challenges to the present routing, signaling and UNI protocols.

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
