摘要
为了显著提升弹性光前传(EOF)网络的能效,提出了一种EOF中的功能分割选择与资源分配优化方案。该方案通过引入改进的Lyapunov漂移技术,解决了功能分割与资源分配中复杂的时间平均随机优化难题,实现了网络资源的动态高效调配。此外,还深入探讨了天线端口数量扩增与光纤频谱粒度细化对方案性能产生的积极效应。仿真结果表明:相较于传统的基于光前传的云无线接入网(C-RAN),该方案不仅大幅降低了平均功耗,降幅高达70%,而且确保了前传延迟维持在250μs以下,展现了卓越的性能优势。
In order to significantly improve the energy efficiency of elastic optical forward(EOF)networks,a functional segmentation selection and resource allocation optimization scheme in EOF is proposed.This scheme solves the complex time averaged stochastic optimization problem in functional segmentation and resource allocation by introducing improved Lyapunov drift technology,achieving dynamic and efficient allocation of network resources.In addition,the positive effects of increasing the number of antenna ports and refining the fiber spectrum granularity on the performance of the scheme were also thoroughly explored.The simulation results show that compared with the traditional cloud wireless access network based on optical fronthaul(C-RAN),this solution not only significantly reduces average power consumption by up to 70%,but also ensures that the forward latency is maintained below 250滋s,demonstrating excellent performance advantages.
