> 中文摘要: 组播通信路由技术是视频广播、计算机会议、CSCW()等新型分布式计算的关键技术.提出了基于分布式遗传算法的共享树组播路由算法,包括包交换的网络组播树的建立、组播树的动态维护和计算满足特定时延和时延抖动限制的近似斯坦利最小树算法等.利用它可以实现在给定网络和组播需求的情况下,在组成员间寻找动态的组播树,并使该树覆盖所有的成员,并约束网络费用达到最小.进而解决树状路由的建立以及树状路由的动态维护等问题.
Abstract:Multicast routing technology is important in new distributed computing such as video broadcast, video conferencing, CSCW. In this paper, a shared tree routing protocol based on distributed Genetic Algorithms (GAs) is presented, including building and dynamic maintenance of multicast routing tree in package exchange network. Computing of delay bounded Steiner Tree is also presented. With this algorithm, a dynamic constructed multicast routing tree which has a near optimal network cost under the delay bound constraint can be constructed real time. As a result, how to build and maintain a rooting tree is resolved.
