End-to-end congestion control methods, such as TCP and QUIC, are the main ways of avoiding congestion on the Internet, and much research has gone into improving the latency performance of TCP. In a recent paper, we at Domos, describe a fundamental limitation of these methods — they cannot avoid latency spikes. Our paper addresses an awkward problem that is obvious to a part of the community (hello control theory people), but which many researchers and engineers frequently either ignore or overlo...
