The need for high data rates in telecommunications requires the constant search for improvements in these systems, especially in minimizing spectrum idleness in optical network. Currently, a solution to this issue is the elastic optical network, leading to numerous studies on the topic. As such, this article presents a study on elastic optical network, which considers physical layer effects (ASE noise and non-linearities) and their influence on the network layer, via the new PRMLSA problem (Power, Routing, Modulation Level and Spectrum Assignment). In the present study, this problem focuses on power, which directly influences the physical layer effects, obtaining promising results compared to current approaches.

电信中对高数据速率的需求要求不断寻求这些系统中的改进，尤其是在使光网络中的频谱空闲最小化方面。当前，解决此问题的方法是弹性光网络，从而导致对该主题进行了大量研究。因此，本文通过新的PRMLSA问题（功率，路由，调制级别和​​频谱分配），对弹性光网络进行了研究，该研究考虑了物理层效应（ASE噪声和非线性）及其对网络层的影响。 。在本研究中，此问题集中于功率，功率直接影响物理层效应，与当前方法相比获得了可喜的结果。
