一种面向5G前传无源光网络的数字子载波动态分配策略
Digital subcarrier dynamic allocation strategy for 5G fronthaul passive optical network
摘要
Abstract
To address the issue that existing static allocation methods struggle to adapt to dynamic changes in service traffic and to improve the resource allocation efficiency of passive optical network(PON)in fifth-generation mobile communication(5G)fronthaul,a digital subcarrier dynamic allocation strategy for 5G fronthaul PON is proposed.By establishing a multi-objective optimization function(minimizing service loss rate,maximizing subcarrier utilization,and minimizing configuration complex-ity),a health-sharing mechanism is introduced to enhance the algorithm's global search capability,and a dynamic adjustment strat-egy for shared radius is adopted to maintain population diversity.Simulation results show that under a network load of 300 Gb/s,the proposed algorithm reduces the service loss rate by 10%compared to traditional static allocation methods,with subcarrier utilization remaining stable above 90%.关键词
