摘要
应用层组播是一种实现网络中心战环境下一对多战场信息分发的有效途径,在对网络中心战环境下应用层组播研究面临的各类问题进行分析的基础上,重点对组播可靠性问题进行了研究,提出了一种可靠组播策略,通过反压技术和备份缓存的方式来保证端对端传送的可靠性,对组播树的错误恢复算法进行了设计,并提供了一种随机路由的辅助策略来改善可靠组播传送的效率,从而满足战场信息分发的高效和高可靠性需求。
Application-layer multicast is an efficient approach for one-to-many battlefield information dissemination in network-centric warfare. In this paper, reliability of multicast is emphasized based on analysis of the problems in the application-layer multicast research. A reliable multicast strategy is proposed which achieves reliable end-to-end transfer by back-pressure and backup buffer. A recovery algorithm for multicast tree error is designed. To improve multicast efficiency, a random routing strategy is provided. This research will meet the need of high reliability and efficiency of battlefield information dissemination.
