This paper introduces a new way to allocate the modulation format and improves the energy efficiency in elastic optical networks. For every connection request, both the quality of transmission and quality of service requirements are investigated. The allocation of modulation formats is based on both the physical distance and the required number of frequency slots. To improve the energy efficiency, Yen's algorithm is executed for every connection requested, and the lightpath with the lowest power consumption is selected. Numerical results were compared with adaptive modulation algorithms presented in the existing literature. The energy efficiency was improved by up to 27%, the used bandwidth available was reduced by up to 60%, and the blocking probability was decreased by 30% using our proposed adaptive algorithm.

弹性光网络中的自适应调制分配算法

本文介绍了一种分配调制格式的新方法，并提高了弹性光网络中的能量效率。对于每个连接请求，都将调查传输质量和服务质量要求。调制格式的分配基于物理距离和所需的频率时隙数量。为了提高能量效率，对每个请求的连接都执行Yen算法，并选择功耗最低的光路。将数值结果与现有文献中提出的自适应调制算法进行了比较。使用我们提出的自适应算法，能效提高了27％，可用带宽降低了60％，阻塞概率降低了30％。
