基于ATM网络综合自愈策略的研究

Studies of Comprehensive Solution of Self-Healing ATM Networks

首先对 ATM技术的特点、自愈技术的重构路由方案、ATM自愈网的组成以及两种基本的自愈技术进行探讨。然后在满足高优先级的业务及时、准确地到达目的节点 ,针对各种不同业务对服务质量 (Qo S)的不同要求 ,引入了具有多优先级的综合自愈策略。这为保证有较高生存性要求的业务最先得到恢复有现实意义。

We firstly introduce the characteristic of ATM technology ,the re routing scheme of self healing technology, the structure of ATM self healing net and two basical self healing technology .To satisfy different requirements of different services and ensure high PRI arrival at objective node accurately and timely, we offer the multipriority self healing strategy. It's important to ensure higher _PRI service restoration at first.
