Hi, IDRers:
Here is the update of BGP distribution for Traffic engineering performance metrics draft
(http://tools.ietf.org/html/draft-wu-idr-te-pm-bgp-02)
Based on Berlin IDR meeting discussion and offline discussion with ISIS-TE-extension authors.
Thanks for Hannes for helping let this discussion happen.
The changes compared to the previous version includes:

   o  Taking out link utilization metric and channel throughput metric
      from this version and will add link utilization metric back to the
      the next version when there was agreement on what measurement unit is used
      for link utilization.

   o  Some additional texts in BGP extension section 4 to explain how to
      position 'A' bit in the BGP TE performance TLV.

   o  Add two editor notes to explain the status of this draft and open
      issue that need be resolved.

   o  Some additional text in the use case sections to clarify how to
      use these TE performance metrics.

It seems We have reached rough agreement with ISIS/OSPF-TE-extension author on the format and semantic of link utilization metric
That will be added to ISIS/OSPF-TE-extension draft. But it still needs to wait the update of the dependent draft(i.e.,ISIS-TE-extension draft)
And then add link utilization metric into this draft.

The diff is

Regards!

Abstract:
   In order to populate network performance information like link
   latency, latency variation, packet loss and bandwidth into Traffic
   Engineering Database(TED) and ALTO server, this document describes
   extensions to BGP protocol, that can be used to distribute network
   performance information (such as link delay, delay variation, packet
   loss, residual bandwidth, and available bandwidth).
