In this paper, we propose a distributed fault localization protocol for localizing single-link failures in all-optical multi-domain networks. The protocol is based on a limited-perimeter vector matching (LVM) mechanism, which restricts fault localization within a smaller perimeter area and can thus significantly reduce fault localization time. By performing a fault localization process sequentially in the optical domains that an affected lightpath passes through, the protocol can localize both… CONTINUE READING
