NAME OF I-D:

This draft will be published next week

It then should be: 

   http://www.ietf.org/internet-drafts/draft-xu-bgp-gmpls-00.txt
   

SUMMARY
 
   This document describes a method by which client can request circuit
connection through multiple providers. The target environment is the transport
network backbone, where clients are ISPs, CLECs, ILECs etc. and providers are
IXCs, carriers' carrier etc. BGP is used to disseminate route and calculate the
circuit path over the transport backbone networks, and GMPLS is used as
signaling for the connection operations. The primary goal is to support client
network Network Engineering function to adjust its layer 1 network topology in a
multi-provider environment, which is typical in today's transport backbone. This
method is very flexible and scalable. It support different applications include
optical VPN. It is essential to achieve true end-to-end automatic switched
network, which will dramatically reduce the network operation cost.

   These two drafts are targets to PPVPN. My draft is target to CCAMP. It covers
a boarder scope and can be used to solve the problems raised by these two
drafts.


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

   This document fits in the CCAMP WG C-plane section. However, it supports OVPN
which may belong to PPVPN.
 

WHY IS IT TARGETED AT THIS WG
   
   This draft specifies a solution for inter-domain optical networking control
plane, which is under the charter of CCAMP.
  

JUSTIFICATION

   Conventionally, the control plane design follows the sequence of intra-area,
inter-area and inter-domain. However, in today's optical backbone network,
inter-domain interface is equally important and urgent as intra-area interface.
This draft was triggered by direct requests of several service providers.
