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.
