Ballot Text

Technical Summary
 
  The 'Protocol extensions for support of Diff-Serv-aware MPLS Traffic 
  Engineering' document specifies the protocol extensions for support
  of Differentiated-Service-aware MPLS Traffic Engineering (DS-TE).
  This includes generalization of the semantic of a number of IGP
  extensions already defined for existing MPLS Traffic Engineering in
  RFC3630 and RFC-to-be-for 'IS-IS extensions for Traffic Engineering'
  as well as additional IGP extensions beyond those. This also
  includes extensions to RSVP-TE signaling beyond those already
  specified in RFC3209 for existing MPLS Traffic Engineering. These
  extensions address the Requirements for DS-TE spelt out in RFC3564. 

  The 3 Bandwidth Constraint Model documents describe 3 different 
  experimental models for use with the specified (standards track) 
  protocol extensions.

Working Group Summary
 
  It took quite some time, but the WG has consensus to publish the 
  protocol document as a standards track RFC and the 3 Bandwidth
  Constraint Model documents as experimental RFCs.

Protocol Quality
 
  These documents have been reviewed for the IESG by Bert Wijnen.
  The WG Last Call was also send to the isis, ospf, mpls and ccamp
  Working Groups for proper review in those WGs.
