摘要
文章简要介绍了传统的基于链路的恢复技术,并在此基础上提出一种改进的分布式恢复算法,这种新的算法不仅可以恢复链路故障,而且也可以解决节点故障。通过仿真分析可看出,它在故障恢复速度和资源利用率等方面都表现出优越的性能。
A traditional restoration technique based on link is introduced and its defects are shown in this article. Moreover, a modified distributed restoration algorithm is presented, which can solve not only link failures but also node failures. By simulation, the technique shows great performance in terms of restoration time and resource utilization.
