摘要
针对卫星通讯网络具有传输信道不对称、高误码、传输时延长的特点,现有的TCP/IP协议已经不能继续满足空间通信场景的问题,通过分析SCPS-TP对TCP的修正,采用了在Vegas基础上利用修正因子来改变拥塞窗口大小的方法进行拥塞控制,通过仿真验证,结果表明改进后的算法效率要明显优于现有的算法。
Due to the satellite communication network has the characteristics of asymmetric transmission channel, high error rate and long transmission time. The existing TCP/IP protocol can not continue to meet the space communication scenario, through the analysis of the SCPS-TP modification of TCP, by using the method of Vegas based on the use of correction factors to change the congestion window size of congestion control, through the simulation, the improved algorithm efficiency is obviously superior to the existing algorithms.
