A mode conversion-based crosstalk-aware routing, spectrum and mode assignment (MC-CA RSMA) algorithm is introduced in space-division multiplexing elastic optical networks (SDM-EONs) over few-mode fibers. Simulation results show the MC-CA RSMA algorithm can greatly reduce the impact of inter-mode crosstalk on network performance compared with benchmark algorithms.
A proper traffic grooming strategy in dynamic optical networks can improve the utilization of bandwidth resources. An auxiliary graph (AG) is designed to solve the traffic grooming problem under a dynamic traffic scenario in spatial division multiplexing enabled elastic optical networks (SDM-EON) with multi-core fibers. Five traffic grooming policies achieved by adjusting the edge weights of an AG...
Spatial division multiplexing elastic optical networks (SDM-EONs) will become the most important form of future optical transport networks, because it can break the physical limit of achievable capacity in single-mode and single-core fibre. However, spectrum fragmentation issue becomes more serious in SDM-EONs compared with in single EON. Crosstalk-aware cross-core virtual concatenation (CCVC) scheme...
An auxiliary graph (AG) is designed to address traffic grooming under dynamic traffic scenario in spatial division multiplexing enabled elastic optical networks (SDM-EON). Various traffic grooming policies are achieved by adjusting the edge weights of AG, and evaluated through simulation in terms of spectrum efficiency and inter-core crosstalk. Numeric results show that the proposed SDM grooming reduces...
