Please be aware that there is also draft-ietf-tcpm-generalized-ecn-04, which in the current version has a dependency on draft-ietf-tcpm-accurate-ecn for certain cases. Just to state the obvious: These documents are work in progress in TCPM and TCPM always welcomes feedback.

Is this the case? Of course SCE is a competitor to L4S, but the accurate-ecn draft also asserts that there are other uses for accurate-ecn besides L4S (DCTCP and ConEx) . It would be useful if you (the TCPSCE authors ) could state your position on those other uses, for the record. Also, presumably it is incorrect that "There are no IANA considerations", since IANA would need to change the NS bit. Regards, Alex Rodney W.
