The Effect of Router Buffer Size on HighSpeed TCP Performance
Overview This paper studies the effect of the IP router buffer size on the throughput of HighSpeed TCP (HSTCP). The authors are motivated by the fact that in high speed routers, the buffer size is important as such a large buffer size might be a constraint. An analytical model for HighSpeed TCP is derived and it is shown that for small buffer size equal to 10% of the bandwidth-delay product, HighSpeed TCP can achieve more than 90% of the bottleneck capacity. It also shows that setting the buffer size equal to 20% can increase the utilization of HighSpeed TCP up to 98%. On the contrary, setting the buffer size to less than 10% of the bandwidth-delay product can decrease HighSpeed TCP's throughput significantly.
