                 Experimental Codepoint Allocation for
       the Path Computation Element Communication Protocol (PCEP)

Abstract

   IANA assigns values to the Path Computation Element Communication
   Protocol (PCEP) parameters (messages, objects, TLVs).  IANA
   established a top-level registry to contain all PCEP codepoints and
   sub-registries.  This top-level registry contains sub-registries for
   PCEP message, object, and TLV types.  The allocation policy for each
   of these sub-registries is IETF Review.

   This document updates RFC 5440 by changing the allocation policies
   for these three registries to mark some of the codepoints as assigned
   for Experimental Use.

1.  Introduction

   The Path Computation Element Communication Protocol (PCEP) [RFC5440]
   provides mechanisms for Path Computation Elements (PCEs) to perform
   path computations in response to Path Computation Client (PCC)
   requests.

   Further, in order to support use cases described in [RFC8051],
