TCP CONGESTION CONTROL FOR LARGE LATENCY NETWORKS

摘要

A congestion control mechanism for TCP communication sessions is described. The congestion control mechanism adjusts the size of the congestion window based on a number of parallel virtual TCP Hybla connections. The number of parallel virtual TCP Hybla connections used to determine the congestion window can be dynamically adjusted. The enhanced TCP Hybla congestion control mechanism provides improved throughput for heterogenous networks having a high latency link and having possible packet loss.

1. A method for congestion control of a communication session over a heterogeneous network having a high latency link, the method comprising:
determining a round trip time (RTT) for the communication session; determining a normalized RTT (p) based on an equalizing round trip time (RTT0); determining a number, N, of virtual communication sessions; and setting a congestion window (Cωnd) size for the communication session based on N TCP virtual communication sessions and p.
