Hi WG,

We just uploaded a new draft defining the extensions to PCEP for the usage of the Path Residual Bandwdith.
Please see the abstract below.

Thanks
Francesco, Young, Daniele

Abstract:
     The ability of a hierarchy of PCEs to compute accurate end-to-end
   paths across multiple domains is recognized as an important
   requirement in many applications.
      This document describes extensions to the PCE Communication
   Protocol (PCEP) in order to provide new path-related bandwidth
   metrics, which a PCC, like a H-PCE (either stateful or stateless),
   can use from an erstwhile path computation to deploy multiple LSPs
   (having the same end-points and constraints) without additional
   requests, until either the remaining bandwidth along that path is
   all allocated or a deployment fails.
      This information would also be beneficial for implementing
   abstractions of the domain topology, building the abstract
   connectivity incrementally, based only on really used constraints,
   as soon as path computation results are returned.

Please note that it may take a couple of minutes from the time of submission until the htmlized version and diff are available at tools.ietf.org.
