【摘要】 文章提出了一种吉比特级无源光网络(GPON)下支持多业务的动态带宽分配算法。算法由主设备OLT根据改进的AR模型计算并预测各ONU的流量,从设备ONU无需上报请求。仿真结果表明该算法对GPON系统下的多业务均能提供良好的QOS和公平性。更多还原

【Abstract】 This paper proposed a new DBA scheme based on AR model over GPON.OLT uses modified AR model to predict all traffic flows,ONUs need not to report their request.Simulation shows that this whole new algorithm provides strong support on multi-service QOS and fairness demands.更多还原
