摘要

提出了一种基于遗传算法的WDM网络路由和波长分配方法。两个传输损害被添加到通常的路由约束集中。它们分别是偏振模色散(PMD)和放大自发发射(ASE)。通过仿真，我们发现在设备成本方面节省了大量资金，优化了波长转换器和PMD补偿器的位置。此外，该技术限制了级联放大器的数量，减少了波长转换的次数，提高了光信号质量。

Optical network optimization with transmission impairments based on genetic algorithm

We propose routing and wavelength assignment in WDM networks based on a genetic algorithm. Two transmission impairments are added to the usual set of routing constraints. They are polarization mode dispersion (PMD) and amplified spontaneous emission (ASE). Through simulation, we find substantial savings in terms of equipment cost, optimizing the placement of wavelength converters and PMD compensators. Also, the proposed technique limits the number of cascaded amplifiers and reduces the number of wavelength conversions, enhancing the optical signal quality.
