- YZF 9y agoDo you know if any experimental results of sharing with the other congestion avoidance flavors are available somewhere? Historically this requirement for backwards compatibility has been a big problem. Maybe YouTube is getting better but other web traffic is getting hosed?

- YZF 9y agoCool. Thanks! I worked on a UDP congestion avoidance algorithm that had bandwidth/latency feedback built into the protocol and had to deal with some of the same issues.
