我们考虑在WDM网状网络中快速链路故障定位的光层监测方案。提出了一种新的监控路径概念。它不同于现有的监测周期（m-cycle）概念，消除了周期约束。因此，m-trail提供了一种更灵活的全光学监测结构，其包括作为特殊情况的简单、非简单的m-循环和开放的trail。以最小化总监测费用为目标，建立了m试验设计的整数线性规划模型。数值结果表明，基于m-trail的方案明显优于基于m-cycle的方案。
We consider optical layer monitoring schemes for fast link failure localization in WDM mesh networks. A new concept monitoring trail (m-trail) is proposed. It differs from the existing monitoring cycle (m-cycle) concept by removing the cycle constraint. As a result, m-trail provides a more flexible all-optical monitoring structure which includes simple, non-simple m-cycles and open trails as special cases. Aiming at minimizing the total monitoring cost, an integer linear program (ILP) is formulated for m-trail design. Numerical results show that the m-trail based scheme significantly outperforms its m-cycle based counterpart.
