     Experimental Codepoint Allocation for Path Computation Element
                     communication Protocol (PCEP)

Abstract

   IANA assigns values to the Path Computation Element (PCE)
   communication Protocol (PCEP) parameters (messages, objects, TLVs).
   IANA established a new top-level registry to contain all PCEP
   codepoints and sub-registries.  The allocation policy for each new
   registry is by IETF Consensus.

   This document seeks to mark some codepoints for experimental usage of
   PCEP.

1.  Introduction

   The Path Computation Element communication Protocol (PCEP) provides
   mechanisms for Path Computation Elements (PCEs) to perform path
   computations in response to Path Computation Clients (PCCs) requests.

   In section 9 of [RFC5440], IANA assigns values to the PCEP protocol
   parameters (messages, objects, TLVs).  IANA established a new top-
   level registry to contain all PCEP codepoints and sub-registries.
   The allocation policy for each new registry is by IETF Consensus as
   described in [RFC5226].  Specifically, new assignments are made via
   RFCs approved by the IESG.  Typically, the IESG will seek input on
   prospective assignments from appropriate persons (e.g., a relevant
