| 摘 要： | 目前对Vegas拥塞避免机制在SCPS—TP协议上的应用已经有了一定的研究；由于在航天测控网中存在着网络拓扑结构改变现象，这会严重影响Vegas机制的性能。本文提出一种基于BP神经网络的Vegas改进算法，设法减小航天测控网网络拓扑结构改变对Vegas机制性能的影响。仿真实验表明，该算法明显提高了SCPS—TP协议在航天测控网中的数据传输性能。

| Abstract: | The SCPS -TP was put forward to meet the space data communication environment based on the traditional TCP communication protocol, and has some applications in TT＆C network. At present, there is some study about Vegas congestion avoidance applied in SCPS -TP. In TT＆C network, the change of the network topology will affect the performance of Vegas. Based on BP neural network, this paper puts forward an improved Vegas, tries to reduce the influence of network topology change. Simulation results show that, the improvement can enhance the data communication performance of SCPS -TP in TT＆C. |
