Model of Improving Performance of Heterogeneous Network Based on SACK TCP
Hui Wang · Jisuanji gongcheng · 2009
With the development and interconnection of satellite networks,wireless networks and other heterogeneous network,the TCP performance of current widespread use is greatly affected in the network environment of a long delay and high bit error rate. This paper studies the congestion control and congestion restoration strategy of PEP with TCP Selective Acknowledge(SACK) protocol and proposes a PEP SACK congestion control algorithm that does well on improving performance of TCP in a long delay and high bit error rate of the network environment,based on the theoretical model that installing a Performance Enhancing Proxies(PEP) of transmission control functions at the border of heterogeneous network.
