IETF RFC 5872 PDF

Introduction

This document relaxes the IANA rules for the Protocol for Carrying Authentication for Network Access (PANA) [RFC5191]. Rules for the following protocol fields, all defined in [RFC5191], are affected:

o Message Types

o Message Flags

o Attribute-Value Pair (AVP) Flags

o Result-Code AVP Values

o Termination-Cause AVP Values

The rationale for this update is that there can be situations in which it makes sense to grant an allocation under special circumstances. At the time of this writing, the IETF is in the process of approving one such allocation. By changing the current IANA rules to allow for IESG Approval [RFC5226] as well, it has become possible for the Internet Engineering Steering Group (IESG) to consider an allocation request, even if it does not fulfill the default rule. For instance, an experimental protocol extension could perhaps deserve an allocation from a field of reserved bits, as long as a sufficient number of bits still remain for other purposes, and the PANA community is happy with such allocation.
