【摘要】：为了增强卫星网络中TCP协议的性能,首先提出了一种卫星链路下的TCP性能模型,该模型可以反映出带宽约束下TCP性能相关参数对有效吞吐率的影响;其次,基于该模型提出了一种动态规划解决方案,通过求解吞吐率代价函数,得到优化的数据传输策略,该方案不仅能够方便地平衡卫星基站对TCP吞吐率或公平性的要求,还可帮助TCP协议适应卫星衰减链路的各项特征变化。仿真试验表明:该算法能够有效地改进卫星传输TCP的性能。
[Abstract]:In order to enhance the performance of TCP protocol in satellite networks, a TCP performance model based on satellite links is proposed, which can reflect the influence of TCP performance parameters on the effective throughput under bandwidth constraints. Based on this model, a dynamic programming solution is proposed. By solving the throughput cost function, an optimized data transmission strategy is obtained. This scheme not only can easily balance the requirements of TCP throughput or fairness for satellite base stations. It can also help the TCP protocol to adapt to the variation of satellite attenuation link characteristics. Simulation results show that the proposed algorithm can effectively improve the performance of satellite transmission TCP.
