Fault localization in all-optical linear networks

Abstract

The paper investigates single-link fault localization in all-optical networks in a line topology in which a single monitoring node (MN) can localize shared risk link group (SRLG) faults by inspecting the optical bursts traversing through it. We investigate relevant problems in the proposed fault monitoring approach, including m-trail allocation, burst launching time scheduling, and node switch fabric configuration, where constructions are developed to derive optimal solutions and are further examined in numerical experiments.
