摘要
针对高速移动环境的网络特性,提出了基于多种无线网络接口的并行传输机制,以及数据通信流程和管理控制机制,为用户提供了一条由多种不同的链路整合成的透明逻辑链路,自动处理网络的水平切换和垂直切换问题,从而提高网络吞吐量和可靠性,实现流量的负载均衡。在高速列车上的实际测试表明,系统丢包率问题得到了改善,数据吞吐量得到了明显提高。
For wireless high-speed mobile network characteristics,a multi-interface based scheme of concurrent multipath trans-mission is introduced.Its communications procedure as well as management control mechanism is designed.Aiming at improving the network throughput and reliability,and at achieving a better load balance,the scheme provides a logic link above multiple wireless links,which can complete the horizontal handoff and vertical handoff automatically.Results of trials on high-speed train show that the network throughput is significantly improved,and packet loss rate is decreased by using the modified partially-relia-ble stream control transmission protocol.
