摘要
FAST-TCP协议与HSTCP协议都是面向高速网络的传输控制协议,其中FAST-TCP协议减少了传输丢包,但启动时间较长,HSTCP协议使用改进的拥塞反馈系数虽然提高了传输中后期的带宽利用率,却没有能够减少丢包。提出的NHFTCP协议拥塞控制算法,通过改变静态参数α为动态参数加强对网络动态变化的敏感度,减少启动时间和丢包率,最后用仿真实验验证改进效果。
FAST - TCP and HSTCP both are protocols used in high - speed network, FAST - TCP＇ s start time is longer than HSTCP＇ s,but it＇s packet loss rate is smaller than HSTCP＇ s, NHFTCP,a improven tcp represented in this paper, has a smaller start time and less packet loss rate, and it is more sensibility than others by it＇s dynamic parameter α . Finally, the simulation result of the NHFTCP proven that it is better in transmiting than original,
