> the problem with tcp is that it conflates congestion loss with error loss. this causes backoff, ergo poor performance under conditions such as lossy links, handovers etc. etc. Indeed. But, while there are many other congestion handling protocols that are frequently used on smaller networks [1], is there anything better than TCP style that is thought to work on "Internet scale"? [1] E.g. Infiniband has some kind of credit/token based flow control, producing a lossless fabric. There's even stuff like that for Ethernet, e.g. https://en.wikipedia.org/wiki/Audio_Video_Bridging https://en.wikipedia.org/wiki/Audio_Video_Bridging has 802.1Qav, https://en.wikipedia.org/wiki/Credit-based_fair_queuing https://en.wikipedia.org/wiki/Credit-based_fair_queuing
