摘要 提出一种基于动态分组的以太网无源光网络(EPON)带宽分配算法。设计动态组成员策略,动态分配各个光网络单元(ONU)的上行带宽。通过获取的ONU负载情况,计算各个ONU权重,根据计算的权重分配剩余带宽,并根据负载变化,调整各个分组的组成员。仿真结果表明,该算法的平均包延时较小。 This paper proposes a bandwidth allocation algorithm for Ethernet Passive Optical Network(EPON) based on dynamic grouping.It designs dynamic groups strategy,allocates Optical Network Unit(ONU) uplink bandwidth dynamically.Based on the loads of each ONU,it calculates each ONUs' weight,and allocates bandwidth for each ONU.According to the change of load,it adjusts the groups' numbers.Simulation results show that the proposed algorithm's average packet delay time is lower.
