摘要

针对WDM光网络中的单链路故障，提出了一种新的基于链路的哈密顿周期保护(LBHCP)方案。从理论分析和仿真结果可以清楚地看出，LBHCP比以往基于路径的共享保护方案具有更好的资源利用率和更快的恢复时间。

A New Link-Based Hamiltonian Cycle Protection in Survivable WDM Optical Networks

In this paper, we propose a new link-based Hamiltonian cycle protection (LBHCP) scheme for tolerating the single-link failure in WDM optical networks. From theoretical analysis and simulation results, we can clearly see that LBHCP has better resources utilization ratio and faster recovery time than previous path-based shared protection scheme.
