The advent of Elastic Optical Networks (EON) has led to significant improvements in optical network spectrum utilization when compared to Wavelength Division Multiplexing Optical Networks. However, the EON brought challenges to be explored, notably the Power, Routing, Modulation Level and Spectrum Assignment (PRMLSA) problem. This article aims to explore techniques for the PRMLSA problem, being developed two strategies named Shortest and Least Allocated (SLA) Path and Route-Based Spectrum Assignment (RBSA), which, respectively, include the link power spectral density inspection dynamic for routing and a physical layer factor (distance traveled) for Spectrum Assignment. Furthermore, a simplified version of the Adaptive Power Assignment (APA) [1] algorithm is presented, in which a power value between the minimum necessary and the maximum allowed is assigned to the signal. The simultaneous use of the SLA and RBSA algorithms resulted in locks of up to 0.00132%, being more than 10 times lower than the 0.0164% of the Shortest-Path and First-Fit algorithms. While the simplification of the APA resulted in 18.38% of the execution time of its respective original version, but with an increase in the blocking probability, which went from 0.016% to 0.031%, despite still being below conventional techniques, as the Constant Power Assignment strategy.

与波分复用光网络相比，弹性光网络 (EON) 的出现显着提高了光网络频谱利用率。然而，EON 带来了需要探索的挑战，特别是功率、路由、调制级别和​​频谱分配 (PRMLSA) 问题。本文旨在探索解决 PR​​MLSA 问题的技术，正在开发两种名为最短和最少分配 (SLA) 路径和基于路由的频谱分配 (RBSA) 的策略，它们分别包括用于路由的链路功率谱密度检查动态和频谱分配的物理层因子（行进距离）。此外，还提出了自适应功率分配 (APA) [1] 算法的简化版本，其中将最小必要和最大允许之间的功率值分配给信号。同时使用 SLA 和 RBSA 算法导致锁定率高达 0.00132%，比 Shortest-Path 和 First-Fit 算法的 0.0164% 低 10 倍以上。虽然 APA 的简化导致其各自原始版本的执行时间减少了 18.38%，但阻塞概率增加，从 0.016% 增加到 0.031%，尽管仍然低于传统技术，作为恒定功率分配战略。
