| 摘 要： | 容错性和可恢复能力被认为是QoS(服务质量)路由的又一重要方面。针对QoS路由的可恢复性问题,提出了一种使用增强Hello协议的以四阶段为基础的可恢复QoS路由处理机制,并详细描述了每一阶段涉及的关键问题。同时,还对此机制进行了仿真试验,以验证其可行性。最后得出结论:此机制的使用可以为通信网络增加一定的智能性。

| Abstract: | Fault tolerance and path restorability are recognized as other important facts of QoS(Quality of Service) routing. In this paper we propose a relatively integrated and four phases based mechanism for restorable QoS routing by using an enhanced Hello protocol, and describe the key problems of each phase in detail. In addition, we also simulate the mechanism to show its availability. We conclude that we can add some intelligence to the communication networks by utilizing this mechanism. |
