Abstract

The paper presents a Q-learning based dynamic routing algorithm for C+L band elastic optical networks (EONs) considering fiber impairments such as cross-phase modulation (XPM), self-phase modulation (SPM), amplified spontaneous emission (ASE), and inter-channel stimulated Raman scattering (ISRS). The effect of fragmentation is considered in the Q-learning process in addition to considering constraints related to spectrum continuity, contiguity, and non-overlapping. Three classical spectrum allocation strategies, first-fit, last-fit, and exact-fit are used after the Q-learning routing algorithm. The proposed routing, modulation, and spectrum allocation (RMSA) approach is shown to have a lower blocking probability compared with using K-shortest path routing combined with the three classical spectrum allocation strategies.

基于q -学习的C+L波段弹性光网络中感知损伤和碎片的动态路由、调制和频谱分配

本文提出了一种基于Q学习的C+L波段弹性光网络动态路由算法，该算法考虑了交叉相位调制（XPM）、自相位调制（SPM）、放大自发发射（ASE）和通道间受激拉曼散射（ISRS）等光纤损伤。在Q学习过程中，除了考虑与频谱连续性、邻接性和不重叠相关的约束外，还考虑了碎片的影响。在Q学习路由算法之后，使用了三种经典的频谱分配策略，第一次拟合、最后一次拟合和精确拟合。与使用K最短路径路由和三种经典频谱分配策略相结合相比，所提出的路由、调制和频谱分配（RMSA）方法具有更低的阻塞概率。
