一种改进HSTCP公平性的拥塞控制算法

An Algorithm of Congestion Control on Improving Fairness of HSTCP

标准传输控制协议在高速、长距离等应用条件下存在网络带宽不能充分利用的问题,高速传输协议的提出可以解决此问题,但在数据包往返时延上存在较大不公平性.在分析传输公平性基础上,通过离散事件网络模拟器进行公平性模拟验证,提出一种通过添加公平因子改进高速传输协议公平性的算法,经仿真验证,该算法减轻了因RTT不同造成的不公平性.

Standard TCP can not make full use of network bandwidth in the condition of high-speed and long distance. High-speed TCP has been proposed to solve this problem, but has severe RTT unfairness. Though analyzing and simulating, an algorithm based on congestion control is put forward to improve the fairness by adding fair factor. Simulation experiments show that the modified algorithm can reduce the unfairness of different RTT effectively.
