| 摘 要： | 生存性是当前ATM网络中亟待解决的问题。文章针对目前恢复机制的缺点,提出了基于VC、VP层的综合恢复框架。在该框架下引入生存重要性加权恢复率,来表征各种不同服务要求下网络的生存性;提出了三种新的综合恢复机制,分析了各种恢复机制的适用条件。模拟结果显示该框架能够灵活地提供关键服务的优先恢复,有效地提高了整个网络的生存能力。

| Abstract: | Survivability is an important issue in modern network . To solve the shortcoming of the existed survivability mechanism, the integrated restoration frame based on VC and VP is presented. The weighted restoration ratio of survivability importance is introduced to describe the network survivability under different requirement of various services. Three kinds of new integrated restoration mechanism under the frame are introduced and their suitable conditions are discussed. The simulation shows that the integrated restoration frame could provide the survivability of the crucial service in priority flexibly and improve the survivability of the network. |
