As Dave points out, and probably his strongest point,
this is yet another attempt to have sources classify thier
traffic for HIGHER priority or LOWER latency and ignore or
hand wave away the security (DOS) implications that causes.

You can do that type of thing in a controlled situation,
even as large as a whole AS, but this can never succeed
at the scale of "Internet."

Yes, please, everyone read it again and comment on it,
it is very far along in the process now.

I concur that a good, concise and complete definition of "sparse flow" would be useful.
I would also like to see a good glossary of all the terms tossed around so often,
FQ, CoDel (vs FQ_CoDel vs non FQ Codel which is often ambigous in scope as to which
of the three are actually being referenced)

And from another thread calling things "Classic" needs to die,
it is about as good as calling things "New", it is not Classic ECN,
it is RFC3168 ECN, it is not Classic TCP, it is RFC793 TCP, etc al.
