Technology of Multi-Path Routing Relay Used on the Business of the Broadcast TV

广电业务中宽带接入系统的中继技术能够提高系统的覆盖率和频率资源利用率,而中继路由技术是中继技术研究的重要环节.文中提出一种支持多路径的中继路由技术.该技术包括路由发现,维护和管理,和中继的选择机制,能够动态的根据网络的变化选择相应的中继.仿真表明,该多路径的路由选择技术在节省带宽资源和流量控制的基础上,增加了系统的吞吐量,减少了网络时延,提高了网络的性能.

The technology of the relay can improve the coverage and the spectrum utilization in broadband access system used on the business of the broadcast TV. Meanwhile, routing is a key part in the study of relay technology. A multi-path routing algorithm is proved in this work. The algorithm includes route discovery, route maintenance, route manage and the mechanism of the relay selection. It can adapt to the change of the network and select the ex- tract relay. The simulation shows that the algorithm can improve the performance of the network in the throughout and time delay, with saving the source of system bandwidth and traffic balance.
