Crosstalk-aware provisioning strategy with Dedicated Path Protection for elastic multi-core fiber networks

摘要

Space division multiplexing (SDM) over multi-core fiber (MCF) is advocated as a promising technology to overcome the capacity limit of the current single-core optical networks. Network survivability has become a more important concern to guarantee the QoS of more plentiful network traffics. In this paper, we have an investigation about dedicated path protection with considering inter-core crosstalk (XT) in elastic MCF networks. To minimize the influence of XT and blocking probability, a novel crosstalk-aware provisioning strategy with dedicated path protection (CaP) is proposed. Simulation results show that the proposed CAP strategy can perform better than the crosstalk unaware provisioning strategy (CuP), such as modified First-Fit (FF) strategy, in terms of blocking probability, and resource utilization.
