在计算机通信的实际应用中，组播（multicasting）技术日益重要，但由于网络节点处理信息的能力不同，有些节点并不具备组播能力，为此该文用节点的度约束来表示每个节点所具备的组播能力，研究在网络节点具有不同组播能力的路由问题，提出了一种新的解决此问题的利用局部信息的组播路由算法。 In practical applications of computer communication, multicasting technology is increasingly important. However, because of the different ability of network nodes to process information, some nodes do not have multicast capability. Therefore, this paper uses the degree constraint of nodes to represent each node With the multicast capability, this paper studies the routing problem with different multicast capacity in network nodes, and proposes a new multicast routing algorithm that uses local information to solve this problem.
