Effectiveness of TCP SACK, TCP HACK and TCP Trunk Over Satellite Links

Tags:
tcp - ip

Overview This paper reports the study on the performance enhancements of two extensions to the standard TCP implementation - Selective Acknowledgement (SACK) and Header Checksum (HACK) - over satellite links that are characterized by high latency and high bit error rate. The paper also examines the effectiveness of TCP Trunk, an edge-to-edge aggregation and congestion control mechanism, over the satellite link. This study on the effect of varying the TCP window size over long latency link for New Reno, SACK, HACK and TCP Trunk implementations show that increasing window size does improve the performance, but only up to a certain value of the window size, and a further increase actually reduces the performance.
