Abstract

This work studies the energy-minimized multi-layer operation of IP over flexible optical networks, under a dynamic traffic scenario. We extend a multi-layer connection establishment algorithm to jointly optimize the energy consumption of both IP and optical layers. We compare the performance of the proposed energy-aware multi-layer connection establishment algorithm when applied to fixed-grid MLR and flexible optical networks, with that of an energy-unaware solution. We observe that energy savings can be achieved especially at the optical layer, when the proposed energy-aware algorithm is applied to a flexible, as opposed to a fixed-grid MLR optical network, while we also observed a tradeoff between blocking probability and energy efficiency in the case of flexible optical networks.
能量感知的多层柔性光网络运行
本文研究了动态业务场景下柔性光网络上IP的能量最小化多层操作。我们扩展了一种多层连接建立算法,以共同优化IP层和光层的能耗。我们比较了所提出的能量感知多层连接建立算法应用于固定网格MLR和柔性光网络时的性能,以及能量不感知的解决方案。我们观察到,与固定网格MLR光网络相反,当所提出的能量感知算法应用于柔性光网络时,可以实现节能,特别是在光层,同时我们还观察到在柔性光网络的情况下,阻塞概率和能源效率之间的权衡。
