Abstract

The paper investigates a novel monitoring trail (m-trail) scenario that can enable any shared protection scheme for achieving all-optical and ultra-fast failure restoration. Given a set of working (W-LPs) and protection (P-LPs) lightpaths, we firstly define the neighborhood of a node, which is a set of links whose failure states should be known to the node in restoration of the corresponding W-LPs. A set of m-trails is routed such that each node can localize any failure in its neighborhood according to the ON-OFF status of the traversing m-trails. Bound analysis is performed on the minimum bandwidth required for the m-trails. Extensive simulation is conducted to verify the proposed scheme.
