摘要

为了降低空分复用弹性光网络（Space Division Multiplexing Elastic Optical Networks，SDM-EONs）的自发辐射噪声和非线性物理损伤问题对业务传输性能的影响，提出基于辅助图的比特加载和物理损伤感知资源分配（Bit Loading and Physical Impairment-sensing Resource Allocation，BL-PIRA）方法. 在BL-PIRA中，使用辅助图实现业务多策略最小代价优化的路由选择；采用比特加载机制为业务选择满足芯间串扰和非线性物理损伤的纤芯和频谱块. 仿真结果表明，所提BL-PIRA能降低业务阻塞率，提高频谱利用率.

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 blocking probability and improve spectrum utilization.
