TCP Behavior in Sub-Packet Regimes, Chen, J., Iyengar, J., Subramanian, L., & Ford, B. (2011, June). In Proceedings of the ACM SIGMETRICS joint international conference on Measurement and modeling of computer systems, 157-158. ACM.
Many network links in developing regions operate in the sub-packet regime, an environment where the typical per-flow throughput is less than 1 packet per round-trip time. TCP and other common congestion control protocols break down…To understand TCP’s behavior in this regime, we propose a model particularly tailored to high packet loss-rates and relatively small congestion window sizes.
