摘要
为了进一步提高时延大和误码高的同步通信卫星传送数据包效率,提出了一套卫星数据通信传送控制协议(TCP)的跨层设计方法。论述了TCP协议层的流量控制机制和介质访问控制(MAC)协议层的差错控制机制。通过构建的跨协议层的卫星链路网关仿真模型,实验验证了所提方法的正确性,结果表明该设计方法比以往只改进TCP层协议做法,在传输层统计吞吐量提高约三倍多。
To improve efiiciency of transferring satellite packets on GEO satellite links with high delay and high error-bits, some design methods and policies are presented on satellite data communication with a new cross-layers Transmission Control Protocol （TCP）protocol. The Trafiic control mechanism on TCP layer and error control mechanism on Media Access Control（MAC）layer are discussed. Finally, based on simulation Model and its experiments of the satellite link gateway with the cross-layers protocol, the statistical throughput with the proposed design is increased by about three times of the method of just improving TCP protocol.
