Abstract

This paper proposes a novel joint resource allocation technique for flexible-grid systems by utilizing non-dominant sort genetic algorithm (NSGA-II) in a multi-objective optimization framework. It pioneers the implementation of an evolutionary mechanism to optimize resources as means of mitigation of physical layer impairments. This investigation initially introduces a proposal in which bandwidth reduction, maximization of the minimum signal-to-noise ratio (SNR) margin, and minimization/maximization of the sum of SNR margins are studied under dual-objective Pareto analysis in the link-level scenario. Later, the technique extends existing provisioning strategies for network planning by targeting the reduction of blocking and spectral utilization of optical connections.

一种新的光网络柔性电网传输进化规划技术

在多目标优化框架下，利用非优势排序遗传算法(NSGA-II)，提出了一种柔性网格系统联合资源分配的新方法。它率先实施了一种进化机制，以优化资源，作为减轻物理层损伤的手段。本研究首先提出了一种建议，该建议在链路级场景的双目标Pareto分析下，研究带宽减少、最小信噪比(SNR)边际最大化以及信噪比边际之和的最小化/最大化。随后，该技术通过减少光连接的阻塞和频谱利用率，扩展了现有的网络规划供应策略。
