The IESG has received a request from the Path Computation Element WG
(pce) to consider the following document:
- 'Conveying Vendor-Specific Constraints in the Path Computation Element
   communication Protocol'
  <draft-ietf-pce-rfc7150bis-01.txt> as Proposed Standard

The IESG plans to make a decision in the next few weeks, and solicits
final comments on this action. Please send substantive comments to the mailing lists by 2014-12-24. Exceptionally, comments may be
sent to instead. In either case, please retain the
beginning of the Subject line to allow automated sorting.


   The Path Computation Element communication Protocol (PCEP) is used to
   convey path computation requests and responses both between Path
   Computation Clients (PCCs) and Path Computation Elements (PCEs) and
   between cooperating PCEs.  In PCEP, the path computation requests
   carry details of the constraints and objective functions that the PCC
   wishes the PCE to apply in its computation.

   This document defines a facility to carry vendor-specific information
   in PCEP using a dedicated object and a new Type-Length-Value (TLV)
   that can be carried in any PCEP object that supports TLVs.

   This document obsoletes RFC 7150.  The only changes from that
   document are a clarification of the use of the new Type-Length-Value
   and the allocation of a different code point for the VENDOR-
   INFORMATION object.
