摘要
为了进一步适应 Internet 网络多媒体业务应用,高性能 Internet 组播路由算法已成为国内外网络研究热点和难点问题之一。分析了组播路由问题的定义和分类;论述了现有的 IP 层组播路由算法,主要包括五种类型:最多路径树算法、最小生成树算法、Steiner 树算法、单约束的 Steiner 树算法和多约束的 Steiner 树算法;并对它们进行比较和评价。最后提出了高性能 Internet 组播路由算法具有的特点和进一步的研究方向。
In order to accelerate the development of multimedia application in Internet, high-performance multicast routing algorithm has been discussed and is becoming an important and difficult research problem in Internet. First multicast routing is defined and categoried in the paper. Secondly, all important multicast routing algorithms are depicted and discussed according to different tree kinds: the SPT algorithm, the MST algorithm, the Steiner tree algorithm, the constrained Steiner tree algorithm and the multi-constrained Steiner tree algorithm. At the same time the paper evaluates and compares them with performance and computing complex. At last the character of high-performance mulricast routing algorithm and the future research work is proposed.
