基于辅助图的比特加载和损伤感知资源分配
Auxiliary Graph-Based Resource Allocation with Bit-Loading and Physical Impairment-Sensing
摘要
Abstract
To decrease the impact of spontaneous emission noise and non-linear physical impairment on the request's transmission performance in space division multiplexing elastic optical networks(SDM-EONs),an auxiliary graph-based bit loading and physical impairment-sensing resource allocation(BL-PIRA)method is proposed in the paper.In the BL-PIRA,the auxiliary graph is introduced to optimize the multi-policy routing selection with lowest cost for the request.Then,the bit loading mechanism is used to select fiber core and spectrum block that meet crosstalk between inter-cores and non-linear physical impairment for the request.The simulation results show that the proposed BL-PIRA can reduce the request's block-ing probability and improve spectrum utilization.关键词
