In protocol specifications documented in RFCs, there is often a need to allocate code points for various objects, messages, or other protocol entities so that implementations can interoperate. Many of these code point spaces have registries handled by the Internet Assigned Number Authority (IANA). Several IETF policies for IANA allocation of protocol parameters are described in RFC 5226 [RFC5226]. Some of them, such as "First Come First Served" or "Expert Review", do not require a formal IETF action before the IANA performs allocation. However, in situations where code points are a scarce resource and/or the IETF community has consensus to retain tight control of the registry content, policies such as "IETF Review" (formerly "IETF Consensus"), or "Standards Action" have been used. Such allocation policies present a problem in situations where implementation and/or deployment experience are desired or required before the document becomes an RFC.

           Early IANA Allocation of Standards Track Code Points


   This memo describes the process for early allocation of code points    by IANA from registries for which "Specification Required", "RFC    Required", "IETF Review", or "Standards Action" policies apply.  This    process can be used to alleviate the problem where code point    allocation is needed to facilitate desired or required implementation    and deployment experience prior to publication of an RFC, which would    normally trigger code point allocation.  The procedures in this    document are intended to apply only to IETF Stream documents.

   This document obsoletes RFC 4020.
