摘要
本文指出FAST TCP协议参数的本质及其重要性质,设计包含各FAST TCP平均发送持续时间的李亚普诺夫函数,证明当网络中各瓶颈链路处于饱和时,设置各瓶颈链路的饱和度作为期望平衡点时,可实现整个网络中各连接流量比例公平的同时实现最大效用,大时间尺度稳定和较小的FAST TCP连接平均发送持续时间。提出FAST TCP端只要根据期望平衡点和随机连接数的数学期望,动态选取FAST协议参数算法。NS-2仿真结果表明该算法是有效的。
This paper discusses the essence and important property of FAST TCP protocol parameter.Lyapunov function including each FAST TCP lasting time of average transmission proves that when bottleneck links are in saturation,which is set as an desired equilibrium point,the proportion fairness of connection flow in the whole network and maximum utility can be both achieved.The paper points out that on the end of FAST TCP,protocol parameter algorithm can be selected according to the desired equilibrium point and the mathematical expectation of the numbers of stochastic connection,which is verified by NS-2 simulations.
