Based on our large scale experiments, we are pursuing efforts in the IETF to standardize TCP’s initial congestion window to at least ten segments. Preliminary experiments with even higher initial windows show indications of benefiting latency further while keeping any costs to a modest level. Future work should focus on eliminating the initial congestion window as a manifest constant to scale to even large network speeds and Web page sizes.
IW10, while improving elapsed times, imposes higher queuing delay than IW3
However, if self-congesting, IW3 is more aggressive in terms of queuing delay
AQM (RED) failed to control the increase in the queuing delay
