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-Variable that
can be carried in any existing PCEP object.

This document is a product of the Path Computation Element Working Group of the IETF.

This is now a Proposed Standard.

STANDARDS TRACK: This document specifies an Internet standards track
protocol for the Internet community,and requests discussion and suggestions
for improvements.  Please refer to the current edition of the Internet
Official Protocol Standards (STD 1) for the standardization state and
