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.
