Copa congestion control includes three improvements over the current strategy:
(1) It has a velocity term.
(2) It has a TCP-competitive mode.
(3) It has better inter-flow fairness.
The one downside to Copa is that it allows higher latency at lower bandwidth rates and at higher rates it requires timing that is too precise.
I think that incorporating these ideas from Copa would overall be an improvement. It's also possible that Copa's delay target can be relaxed as flows "settle down" around a target bandwidth to avoid introducing latency.
