Abstract

Optical networks are currently the only technology capable of providing extremely high data transmission rates. Because of this, systems must be increasingly efficient and immune to failures. One way to improve network efficiency is to use dynamic approaches like Adaptive Control of Operating Point, which consists of autonomously choosing the best operating point for optical amplifiers on the link, thus providing the best configuration concerning Quality of transmission. Unlike the previous works that focused on optimizing Optical Signal-To-Noise Ratio, our proposal and analysis are focused on maximizing the transmission rate. In this paper, we compare the results obtained by five different and widely used evolutionary and swarm-based algorithms in the search for maximizing the transmission rate in optical links. We have observed that the differential evolution provided the best results in the analyzed scenarios.

利用进化算法和群体智能定义光学系统中放大器增益以使传输速率最大化

光网络是目前唯一能够提供极高数据传输速率的技术。正因为如此，系统必须越来越高效，并且对故障免疫。提高网络效率的一种方法是采用动态方法，如工作点自适应控制，它包括自主选择链路上光放大器的最佳工作点，从而提供有关传输质量的最佳配置。与以往专注于光信噪比优化的工作不同，我们的建议和分析侧重于最大限度地提高传输速率。在本文中，我们比较了五种不同的和广泛使用的进化算法和基于群的算法在寻找最大传输速率在光链路中得到的结果。我们观察到，在分析的场景中，差异进化提供了最好的结果。
