Pool 3 Values in the Differentiated Services
Field Codepoints (DSCP) Registry

I-D Tag: draft-ietf-tsvwg-iana-dscp-registry-08.txt

DOI: 10.17487/RFC8436
The Differentiated Services (Diffserv) architecture specifies use of
the DS field in the IPv4 and IPv6 packet headers to carry one of 64
distinct differentiated services field codepoint (DSCP) values. The
Internet Assigned Numbers Authority (IANA) maintains a registry of
assigned DSCP values.
This update to RFC 2474 changes the IANA registration policy for Pool
3 of the registry (i.e., DSCP values of the form xxxx01) to Standards
Action, i.e., values are assigned through a Standards Track or Best
Current Practice RFC. The update also removes permission for
experimental and local use of the codepoints that form Pool 3 of the
DSCP registry; Pool 2 Codepoints (i.e., DSCP values of the form
xxxx11) remain available for these purposes.
This document is a product of the Transport Area Working Group Working Group of the IETF.
This is now a Proposed Standard.
