TCP稳态流中慢启动序列对吞吐量性能的影响

The Effects of Slow Start Periods to the Throughput of TCP Steady State

在计算TCP稳态数据流吞吐量时一般都忽略了由于分组丢失而形成的各个慢启动阶段。在考虑TCP稳态数据流中慢启动序列的情况下,对Padhye的经典TCP稳态数据流模型进行了扩展。通过将Padhye的模型与扩展后的模型作比较,证明了在使用Padhye的模型作为多媒体流量控制模型时忽略超时后慢启动阶段的可行性和正确性。

In the calculation of TCP steady state throughput,we generally ignore th e effect of slow start periods after every timeout lo ss indication.In this paper,we exte nded the model derived by Padhye to include the effects of slow start periods after each timeout periods in steady state TCP flow.Based on the comparisons of these two models,we e xperimentally validated the feasib ility of ignoring the effects of slow start periods in TCP steady state flo ws.
