| 摘 要： | 由于卫星通信系统具有的长时延特性以及无线信道误码率高的特点 ,传统的应用于Internet的TCP拥塞控制机制在卫星通信链路上进行TCP数据包传输时不能充分利用网络的吞吐量 ,导致网络效率低下 .因此提出一种新的基于TCP拥塞控制窗口大小的改变新算法TCP Sjump ,旨在有效提高卫星通信链路上的网络利用率 ,并给出了在实际环境中和利用计算机进行仿真试验的研究模型

| Abstract: | TCP performance is limited by the delay inherent in geosynchronous systems and the probability of bit errors found in any wireless system including satellite systems, which lead to the low throughput and inefficiency of the network containing satellite links. We present a new congestion control algorithm, TCP-Sjump, based on the change of congestion window in congestion avoidance to allow better utilize the available bandwidth provided by networks. To verify this new TCP enhancement algorithm, we introduce the test environment via real VSAT system and also the necessary research module in PC simulation experiment. |
