NAME OF I-D:

  Using BGP to distribute flexible QoS information

  http://www.ietf.org/internet-drafts/draft-bonaventure-bgp-qos-00.txt

SUMMARY


   This document proposes a flexible QoS attribute that can be used to
   distribute QoS information with BGP.  The proposed attribute  allows
   to associate a set of supported PHB, transit delay and  bandwidth
   information to an UPDATE message. The flexibility of the proposed
   attribute allows each AS to decide  independently which QoS
   information to redistribute to its peers.

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

This draft fits mainly into the TEWG. Since it provides new BGP
capabilities, it could also be applicable to PPVPN.


WHY IS IT TARGETED AT THIS WG

This document addresses the following item of the TEWG charter :

"The working group may also consider the problems of traffic engineering across autonomous systems boundaries. "

JUSTIFICATION

Within the TEWG, the work has currently focussed on traffic engineering
inside a single IGP area. However, recent draft have started to work
on requirements and solutions to support multi-area TE. The natural
extension would be to consider interdomain TE, which requires BGP extensions
such as the ones discussed in this document.
