Dear Qian: Pretty promising paper. I liked that it tackled congestion on the ack path, among other things.
https://www.techrxiv.org/articles/preprint/TCP_FlexiS_A_New_Approach_To_Incipient_Congestion_Detection_and_Control/19077161/1/files/33905018.pdf I like also that you tackled, inter-rtt fairness, and, ledbat's latecomer advantage problem, and in fig 9, the basic problem with delay based LBE vs AQMs (in that ledbat degrades to reno)... [1] Towards your conclusion... I have always disagreed with the "don't reduce segment size" crowd, btw. If you have a rate where you need to go below 2mss, it doesn't hurt the network to reduce the size of the packet, and you can keep the signal strength up by reducing that size and continuing to sample rtt, to respond quickly. Even if you are only passing a single byte of data, by lowering this below everyone else's 2mss noise floor, you still eventually win, and also you occupy space in packet fifos, reducing overall latency, as bytes=time. IMHO. elsewhere, sub-packet windows are being experimented in bbrv2, I'm told, but not in LBE. I'm also a big believer in packet pacing, and I think this is the first paper I've seen that attempted LBE with it. Thx! Got a git tree?
