I don’t think it’s an accident that a discussion around CoDel evolved into a
discussion around TCP.
If newer TCP CC algorithms can eliminate self-induced bloat, it should still be
possible for queue management to handle older TCP implementations and extreme
cases while not damaging newer TCPs. Beyond that, there may be areas where
queue management can actually enhance the performance of newer TCPs. For
starters, there’s what happens within an RTT, which I suppose can’t be dealt
with in the TCP stack, and referring back to one of Jon’s messages from 11/27,
the possibility for improved signaling from AQM back to TCP on the state of the
queue. Global coordination could make this work better.
p.s.- Apologies for it taking me longer than an RTT to re-read the original
CoDel papers and think through some implications. My original question might
have been smarter.
