摘　　要：在光进铜退的趋势下,以GPON(Gigabit Passive Optical Network)搭建的光纤接入网应用场景不断增多。用户对网络服务质量的要求以及运营商减少建设成本的需求,使得QoS技术发展迅猛。传统的QoS已经不能满足现网的需求,层次化服务质量HQoS(Hierarchical Quality of Service)技术实现了多层次的流量管理,能更好地帮助运营商实现多用户、多业务的服务管理。针对现有接入网HQoS模型,提出了区分组播业务进行单独QoS处理的改进意见,并对改进模型进行了实际应用的模拟测试。测试结果表明,改进模型能够对不同用户采用不同的调度策略,并可针对组播业务做单独的QoS处理。As the optical access is replacing copper access, the application scenarios of fiber access network based on Gigabit Passive Optical Network （GPON） gradually increase. Besides, users＇ requirements on the quality of network services and the operators＇ needs of reducing construction cost facilitate QoS technology to develop rapidly. Therefore, traditional QoS can no longer meet the requirements of present network, while Hierarchical Quality of Service （HQoS） technology realizes multi-level flow management, so it can better help operators achieve multi-user and multi-business service management. Based on HQoS model of existing access network, this paper put forward the improvement suggestions of classifying multicast services and conducting separate QoS processing. Besides, a simulation test of the actual application of the improved model was also carried out. The test result showed that the improved model is able to adopt different scheduling strategies according to different users and separately conduct QoS processing for multicast services.
