NAME OF I-D: Generalized Multi-Protocol Label Switching (GMPLS) Architecture

http://search.ietf.org/internet-drafts/draft-many-gmpls-architecture-00.txt

SUMMARY:

Future data and transmission networks will consist of elements such as
routers, switches, DWDM systems, Add-Drop Multiplexors (ADMs), photonic
cross-connects (PXCs) or optical cross-connects (OXCs), etc that will use
Generalized MPLS (GMPLS) to dynamically provision resources and to provide
network survivability using protection and restoration techniques.

This draft describes the architecture of GMPLS. GMPLS extends MPLS to
encompass time-division (e.g. SDH/SONET, PDH, G.709), wavelength (lambdas)
and spatial switching (e.g. incoming port or fiber to outgoing port or
fiber). The main focus of GMPLS is on the control plane of these various
layers since each of them can use totally different data or forwarding
planes. The intention is to cover both the signalling and the routing part
of that control plane. This draft explains the GMPLS building blocks and how
they fit together.

WHERE DOES IT FIT IN THE PICTURE OF THE SUB-IP WORK

It fits in the CCAMP WG, indeed it fits where the GMPLS signalling fits.

WHY IS IT TARGETED AT THIS WG

This work defines the GMPLS architecture and should be done in the same WG
where GMPLS is specified. It complements the whole GMPLS signalling and
routing efforts and is related to all the CCAMP tasks. It is intended to
describe all the GMPLS building blocks for which there is a broad consensus
and how they fit together.

JUSTIFICATION

An architecture for something as generic as GMPLS is of paramount importance
in order to fit all the pieces together. It will considerably help to
understand what is GMPLS, what it does and how it works. It should be
complemented by a framework document.

We think that this architecture draft should belong to the CCAMP WG. It was
decided during the last IETF in the CCAMP WG that this draft will be
re-published as a CCAMP WG draft, i.e. as
draft-ietf-ccamp-gmpls-architecture-00.txt. It was the consensus of the room
and it was accepted by the working group chairs. We think that this draft
should be developed in the same WG as the GMPLS signalling. This draft is
specifically about GMPLS and does not intend to describe something else.

The GMPLS work is of paramount importance for operators, for many reasons
that were already explained many times in the literature. The large amount
of co-authors on the GMPLS drafts is a measure of the importance of that
work for the industry. It is also one of the first time that the IP industry
really meet the multiple transmission industries, we believe that the IETF,
the sub-IP area and the CCAMP working group are the right places for this to
happen.
