This article presents a new approach related with end-to-end routing, which, owing to quantum-inspired mechanisms of prediction of availability of network resources, results in improved blocking probability of incoming requests to establish transmission paths. The proposed scheme has been analyzed for three network topologies and several scenarios of network load. Obtained results show a significant...
Most of previous research on survivable networks has been focused on protecting the unicast traffic against random failures. In this paper we propose a new approach, called RA (resistant-to-attack), to provide protection of anycast and unicast communications against attacks on irregular (e.g. scale-free) networks. We use the single backup path approach to provide protection against a single node failure...
Most of previous research on survivable networks has been related to unicast communications. In this paper we propose a new approach to network survivability of anycast communications. To the best of our knowledge, anycast defined as one-to-one-of-many technique has not received much attention recently. To provide network survivability, we use the single backup path approach, i.e. each demand has...
In this paper, a novel algorithm optimizing the utilization of backup path resources for survivable WDM mesh grooming networks, based on graph vertex-coloring approach, is proposed. This is the first optimization technique, dedicated to protection-at-connection level (PAC) in WDM grooming networks, such that does not increase the backup path length and thus provides fast service recovery. The concept...
