         Explicit Congestion Notification (ECN) Experimentation
                draft-ietf-tsvwg-ecn-experimentation-01

Abstract

   Multiple protocol experiments have been proposed that involve changes
   to Explicit Congestion Notification (ECN) as specified in RFC 3168.
   This memo summarizes the proposed areas of experimentation to provide
   an overview to the Internet community and updates RFC 3168, a
   Proposed Standard RFC, to allow the experiments to proceed without
   requiring a standards process exception for each Experimental RFC to
   update RFC 3168.  Each experiment is still required to be documented
   in an Experimental RFC.  In addition, this memo makes related updates
   to the ECN specifications for RTP in RFC 6679 and to the ECN
   specifications for DCCP in RFC 4341, RFC 4342 and RFC 5622.  This
   memo also records the conclusion of the ECN Nonce experiment in RFC
   3540, obsoletes RFC 3540 and reclassifies it as Historic to enable
   new experimental use of the ECT(1) codepoint.
