摘　　要：作为EPON组网重要支撑技术的动态时隙分配法是当前智能光网络(ASON)领域研究的热点。该分配法是建立在固定轮询周期前提下基于数据突发性而设计的,但缺乏考虑网络负载和多业务等级(CoS)特性,进而导致一系列QoS问题。论文提出一种时隙均衡调度机制为不同CoS业务进行授权。该机制通过实时计算负载及业务权重来动态调整轮询周期,为每一个ONU的不同等级业务分配授权。授权过程既为每个ONU的CoS提供了带宽保障也兼顾到了负载变化时的丢包率和传输时延。As a dynamic slot allocation method of EPON network is an important supporting technology is the research hotspotin the field of optical communication. The distribution method is based on the premise of fixed period polling data burst based on thedesign,but the lack of consideration of the network load and service level(CoS),which leds to a series of problems. This paperpresents a QoS time slot scheduling mechanism for different authorized CoS business. The mechanism of load and business by com-puting the weights dynamically adjust the polling cycle,assign authorization to different grades of each ONU. Both the authorizationprocess for each of the ONU CoS provides a guarantee of the bandwidth is to take into account the load variation of the transmissionlatency and packet loss rate.
