section 6 addition. (could use more verbiage)
6.3 "An AQM that is ECN aware MUST have overload protection.
It is trivial for a malbehaved application/worm/bot to mark all it's
packets with ECN and thus gain priority over other traffic not ecn marked.
6.4 Enabling ECN at the application layer requires access to the IP header
fields, which are usually
abstracted out completely at the tcp layer, and hard to access from
udp with multiple non-portable
methods to do so. ECN over UDP in new applications such as webrtc
and Quic has great potential for
many other applications, however the same care of design that went
into ECN on TCP needs to go
into future UDP based protocols.
Some other section that may end up here?
ECN marking other sorts of flows (example routing packets) that have a
higher priority than other flows on link-local packets may be of benefit
with wider availability of aqm technologies that are ecn aware...
