摘要

针对空分复用弹性光网络（Space Division Multiplexing-Elastic Optical Networks

SDM-EONs）的芯间串扰和频谱碎片化问题，该文提出一种考虑业务持续时间、光路邻域资源匹配度及芯间串扰的路由频谱纤芯分配算法.在业务的路由选择阶段，该文设计基于光路负载均衡和频谱碎片减少的路由策略；在纤芯选择阶段，设计兼顾纤芯负载及减少纤芯间串扰的纤芯选择方法；在时-频资源块分配阶段，设计考虑时-频资源碎片变化小和邻域匹配度变化小的资源分配方法.仿真结果表明，该文所提算法可以降低网络带宽阻塞率和提高频谱资源的使用效率.

Abstract

To solve the problems of inter-core crosstalk and spectrum fragmentation in space division multiplexing-elastic optical networks(SDM-EONs)

a routing spectrum core allocation with holding time

lightpath’s neighborhood matching degree and inter-core crosstalk(TMD-XT-RSCA) is proposed. In the service routing stage

a routing strategy is designed to balance the lightpath’s load and reduce resource fragment. In the core selection

a core selection method is designed to balance the fiber core’s load and decrease inter-core crosstalk. In the time-spectrum block allocation stage

a resource allocation method through considering small change of time-spectrum fragmentation and small change of neighborhood matching degree is designed. The simulation results show that the proposed TMD-XT-RSCA algorithm can reduce the bandwidth blocking probability and improve the spectrum utilization.
