Achieving accurate and efficient fault localization in large transparent all-optical networks (TONs) is an important and challenging problem due to unique fault-propagation, time constraints, and scalability requirements. In this paper, we introduce a novel technique for optimizing the speed of fault-localization through the selection of an active set of(More)
As the capacity of optical transport networks increases, rapid fault identification and localization become increasingly important. These problems are more challenging than in traditional electronic networks because of optical transparency. In a transparent optical network which does not regenerate optical signals, a fault may propagate to various parts of(More)
Rapid fault identification and localization in optical networks are crucial due to high data rates. These problems are more challenging than in traditional electronic networks because of optical transparency. In a transparent optical network which does not regenerate optical signals, a fault may propagate to various parts of the network from the origin, and(More)
Transparent all-optical networks introduce a challenging problem of achieving efficient and accurate fullcoverage fault-localization. In this paper we present a novel and efficient monitoring approach that exploits the benefits of provisioned user lightpaths for in-band monitoring and achieves complete fault localization coverage at the minimum resource(More)
Rapid fault detection and localization in transparent optical networks is crucial due to the high data rates at which they operate and optical transparency. Furthermore, large alloptical networks require distributed fault-management in order to achieve scalable, accurate, and rapid fault localization. In this work we present an efficient scheme for(More)
