论文摘要
本文解决了灵活的光网络的传输感知收发器分配问题，以进行多个周期计划。所提出的方法旨在考虑使用不一致的扩展高斯噪声（EGN）模型来考虑放大器噪声和非线性通道干扰的最佳带宽变量收发器（BVTRX）。与最近提出的算法相比，提出的解决方案改善了早期计划期间的网络吞吐量和频谱利用率，并在后期分配了较低的BV-TRX。与没有再生器的配置相比，还采用了一种启发式恢复剂放置的方法，可实现多达25％的收发器和50％的频谱利用率。
This paper addresses the transmission-aware transceiver allocation problem of flexible optical networks for a multi-period planning. The proposed approach aims at assigning the best configuration of bandwidth variable transceivers (BVTRX) considering the amplifier noise and nonlinear channel interferences using the incoherent Extended Gaussian Noise (EGN) model. The proposed solution improves the network throughput and spectrum utilization in the early planning periods and allocates lower number of BV-TRXs in later periods in comparison to algorithms presented recently. A heuristic approach to regenerator placement has also been applied achieving up to 25% transceiver and 50% spectrum utilization savings in comparison to configurations without regenerators.
