Summary for Sub-IP Area
NAME OF I-D
draft-xu-bgp-gmpls-01.txt
SUMMARY:
Current CCAMP works focus on intra-domain control plane. This
document focuses on inter-domain control plane. It views the
overall network as a collection of administrative domains,
partitioned by operators according to administrative, technological
or geographical considerations. This document specifies a
BGP/GMPLS based inter-domain solution for setting up circuit LSPs
that span multiple administrative domains. A few extensions and
modifications are proposed to BGP in order to disseminate
appropriate topology information and calculate end-to-end circuit
paths. GMPLS signaling is also extended for the inter-domain
connection operations. The solution specified in this draft is
fundamental for inter-domain operations and can be used as a base
for various applications, e.g. OVPN. It is also very flexible and
scalable.

WHERE DOES IT FIT IN THE PICTURE OF THE SUB-IP WORK:
This work fits in the Control Plane of CCAMP
WHY IS IT TARGETED AT THIS WG:
This draft specifies a BGP/GMPLS based inter-domain control plane
and both control plane and GMPLS are in the charter of CCAMP.
JUSTIFICATION
Solutions for inter-domain is equally important and urgent as
intra-domain solution because (1) backbone transport network is
made of multiple service providers (2) Network Elements of different
technologies are typically partitioned as different domains. (3) many
service providers are looking for inter-domain solutions.
The solution specified in this draft is fundamental for inter-domain
operations and can be used as a base for various inter-domain
applications. It minimizes changes to current protocols and is also
very flexible and scalable. So CCAMP should accept this work.
