| 摘 要： | 文章提出一种基于PIM-SSM的GMPLS组播算法,描述基于PIM-SSM的GMPLS组播算法的具体细节和实现原理,并分析了该算法的可行性和实现方法。该算法只需在分支节点复制组播数据和维护组播路由表,而非分支节点只进行标签交换,在GMPLS网络中建立光标签交换路径和包标签交换路径用于组播数据传输,保证数据快速、安全传输和良好的QOS。

| Abstract: | In this paper, we present a new approach to construct multicast trees based on PIM-SSM in GMPLS networks. This approach utilizes the theory that the branching core routers need to maintain multicast routing and to copy multicast data, but the non-branching core routers only switch lambda and packet labels. GMPLS routers build lambda label switched paths and packet label switched paths. The article describes the theory and implementation of the approach and gives its evaluation. |
