The Space Division Multiplexing with Elastic Optical Networks (SDM-EON) is one of the newest networks to improve transmission capacity and prepare more flexibility compared to conventional EON networks. In SDM-EON, arriving connection demands could be setup efficiently. We consider a multi-core fiber (MCF)-enabled elastic optical network. We introduce two novel metrics as holding time metric (HTM) and coefficient of variant metric (CVM). Based on these metrics, three novel algorithms are introduced to resolve the fragmentation problem and improve blocking probability in SDM-EON; called Coefficient of Variant Metric (CVM); Holding Time Metric (HTM); and Moderate Coefficient of Variant Metric and Holding Time Metric (Mod_CVM_HTM) algorithms. According to our performance evaluation results, our proposed algorithms can reduce blocking probability (BP).

弹性光网络空分复用（SDM-EON）是最新的网络之一，与传统的EON网络相比，它可以提高传输容量并提供更多的灵活性。在SDM-EON中，可以有效地设置到达的连接需求。我们考虑多芯光纤（支持MCF）的弹性光网络。我们介绍了两个新颖的度量标准，例如保持时间度量标准（HTM）和变异系数度量标准（CVM）。基于这些指标，提出了三种新颖的算法来解决SDM-EON中的碎片问题并提高阻塞概率。称为变差系数（CVM）；保持时间指标（HTM）；度量和保持时间度量的中等和中等系数（Mod_CVM_HTM）算法。根据我们的性能评估结果，我们提出的算法可以降低阻塞概率（BP）。
