摘　　要：ATM管理信息网是机动组网的最优先业务,不仅要适应网络拓扑的频繁变化,而且要尽可能低地占用传输资源。基于网络开通的预先规划,在研究RIP、OSPF路由协议的基础上提出了基于ATM组播实现的快速收敛路由算法,该算法通过环路检测机制防止组播风暴发生,路由交互信息由一个ATM信元封装完成,占用极低的传输带宽,通过专用信息格式、入网认证等机制进行了安全设计。该算法适合通信节点不超过20的组网应用,具有很强的抗毁顽存能力。It is the first priority service for the management information to transport in the mobile network, also, occupying as less as possible link bandwidth and adapting to the frequency change of network topology are needed. With given design condition and reference to RIP and OSPF routing technology, the paper presents a fast routing convergence algorithm in which routing information is spread through ATM muhicast and loop detection is designed to avoid multicast storm, the routing information is encapsulated in a single ATM cell, so occupying low bandwidth. In order to ensure network security, special information format and network access authentication technology are applied. By analyzing, the algorithm can be applied in a mobile network with up to 20 nodes and has strong survivability.
