摘要

Elastic optical networks technology in combination with space division multiplexing is playing a major role to fulfil the need of increasing internet traffic. However, it suffers from resource sub-utilization due to the traffic heterogeneity in time and bandwidth domains, and the crosstalk between the adjacent cores in a multi-core fiber link. In this paper, we propose time and bandwidth aware traffic balancing strategies with crosstalk consider-ation to efficiently utilize the spectral resources in MCF based EONs. To this end, we utilize network features and SLA conditions to balance the traffic, in both, the time and the bandwidth domains. In bandwidth domain, we utilize squeezing and splitting with multipath routing, and in time domain, we use sliding and shifting. To further enhance the performance, we use a MCF structure dependent prioritized core allocation based RMCSA strategy. Simulation results indicate superiority of the proposed strategies in terms of different parameters of interest as compared to the benchmark strategies.
