本文提出了两种适用于透明弹性光网络的功率系列路由（PSR）算法：具有归一化距离和插槽可用性的PSR算法（PSRNDA）和具有归一化距离和插槽连续性的PSR算法（PSRNDC）。在我们的分析中，我们考虑了物理损伤、不同的调制格式和比特传输速率以及频谱选择开关（SSS）设备上的损耗。得到了呼叫阻塞概率作为网络负载函数的表达式。将我们提出的算法与文献中的其他算法进行比较，我们的建议克服了所有这些问题。
In this paper, we propose two adaptations of the Power Series Routing (PSR) algorithm for transparent elastic optical networks: PSR algorithm with normalized distance and slot availability (PSRNDA) and PSR algorithm for normalized distance and slot contiguity (PSRNDC). In our analysis, we consider amplified spontaneous emission as physical impairment, different modulation formats and bit transmission rates, as well as losses on spectrum selective switch (SSS) devices. The results are obtained in terms of call blocking probability as a function of the network load. Comparing our proposed algorithms to several others present in the literature, our proposals overcame all of them.
