NAME OF I-D:
G.LSP Service Model framework in an
Optical G-MPLS network
http://www.ietf.org/internet-drafts/draft-duroyon-te-ip-optical-01.txt

SUMMARY

The objective of this draft is to
propose an IP service model for a
non-packet switch capable optical
network where LSPs are dynamically
triggered by the IP layer and
subsequently advertised for IP routing.
The business model assumes that several
IP service domains, some of which
represent different administrative
entities, share the same optical
backbone and focuses therefore primarily
on an overlay model. GMPLS signaling
with UNI support is assumed as
underlying control plane protocol.

This IP Service Model is a framework
proposal to achieve IP Traffic
Engineering over a GMPLS network.

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

TE-WG

WHY IS IT TARGETED AT THIS WG

The draft has for objective to describe
principles for traffic engineering in
the Internet, where the Internet is
based on a collection of PSC and non-PSC
capable devices across several
Autonomous Systems.

The draft should be followed up by other
drafts recommending techniques, and
mechanisms to implement the Services
Model as described.
Several aspects are developed in this
first framework draft:
- New Administrative / Contractual
constraints (Optical SLS concept)
- Constraints brought by the new link
attributes (Non-PSC capable interfaces),

- Traffic Engineering constraints
brought by IP routing

By consequence, the draft belongs into
the work item category
 - BCP documents on ISP uses,
requirements, desires (TEBCPs)

Today there are not so many other drafts
trying to capture the same requirements.

A relatively close draft has been
proposed under the title:
IP Traffic Engineering Actions resulting
in Optical Layer connections,
http://www.ietf.org/internet-drafts/draft-newsome-mgmtplanerqmts-00.txt



JUSTIFICATION

Today TE WG doesn’t explicitly cope with
the different aspects of IP Traffic
Engineering over GMPLS networks. With
this draft as a first step, we are
proposing to open a work item on how to
achieve IP Traffic Engineering over such
a network environment.
