That's very interesting, thank you. I think there should be a way to control retransmission times on the client that would alleviate that problem. Probably taking out tcp connection out of kernel space and controlling the protocol in user space will allow to control the lower level tcp to work nicely with upper levels. But still, is there a possibility of a meltdown on the routers further down the line which might be controlling tcp connections? They would be routers which are not simply passing the ip packets, but working with the protocol in a more elaborate way though, either deep packet inspection or some other network mechanisms?
