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

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 , 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 . 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 Working Group if one exists). With some recent advancement, there is an enhanced need to experiment with PCEP. It is often necessary to use some sort of number or constant in order to actually test or experiment with the new function, even when testing in a closed environment. In order to run experiment, it is important that the value won't collide not only with existing codepoints but any future allocation. This document thus set apart some codepoints in PCEP registry and subregistries for experimental usage.

Some codepoints are requested to be set aside for experimentation with new PCEP messages. The suggested range is 224-255.

Some codepoints are requested to be set aside for experimentation with new PCEP objects. The suggested range is 224-255.

Some codepoints are requested to be set aside for experimentation with new PCEP TLVs. The suggested range is 65280-65535.

IANA maintains the "Path Computation Element Protocol (PCEP) Numbers" at <http://www.iana.org/assignments/pcep>.

Within this registry IANA maintains a sub-registry for PCEP Messages (see PCEP Messages at <http://www.iana.org/assignments/pcep>). Upon approval of this document, IANA is requested to make the following allocations:

Within this registry IANA maintains a sub-registry for PCEP Objects (see PCEP Objects at <http://www.iana.org/assignments/pcep>). Upon approval of this document, IANA is requested to make the following allocations:

Within this registry IANA maintains a sub-registry for PCEP TLVs (see PCEP TLV Type Indicators at <http://www.iana.org/assignments/pcep>). Upon approval of this document, IANA is requested to make the following allocations:

The allocation policy for the IANA request in is "Experimental". As per , IANA does not record specific assignments for any particular use for this policy. The ongoing experiment code point can be maintained at the PCE WG wiki at <https://trac.tools.ietf.org/wg/pce/trac/wiki>. As the experiment/standard progress and an early IANA allocation or RFC publication happens, the IANA defined codepoints are used and experimental code points are freed up.
