基于GEO卫星网络的TCP增强代理模型

TCP Enhancing Proxies Model Based on GEO Satellite Network

为提高在长时延、高误码率和带宽非对称性的卫星网络环境中的TCP性能,在NS2环境下搭建有线网络与卫星网络间的仿真环境,利用性能增强代理(PEP)建立由有线网络、PEP和地球同步轨道卫星网络构成的异构网络体系结构模型。仿真结果表明,该模型能改善卫星网络中TCP的传输性能。

In order to improve TCP performance in the satellite network of a long delay, high bit error rate and asymmetrical bandwidth, this paper builds a heterogeneity network architecture model consisting of limited network, Performance Enhancing Proxies（PEP） and Geosynchronous Orbit（GEO） satellite network by PEP. It builds simulation environment between wired network and satellite network in NS2. Simulation results show the model can improve the performance of TCP in satellite network.
