[Bloat] TCP congestion detection - random thoughts

[Juliusz Chroboczek]

To add to what my honourable prelocutors have said, µTP, which is used by 
modern BitTorrent implementations, uses the LEDBAT congestion control 
algorithm, which is based on delay.  The fact that LEDBAT is crowded out 
by Reno is a desirable feature in this case -- you do want your BitTorrent 
traffic to be crowded out by HTTP and friends.
