Title: Qos characteristic analysis of EPON about dynamic bandwidth allocation
Abstract: In the research of DBA(dynamic bandwidth allocation),much attention has been paid to the utilization rate of the bandwidth.Actually,the Qos of the multi-service supporting net is becoming more and more important.In view of this situation proposed a new al-gorithm of service-based DBA through research,compared the new algorithm with the existing ONU-Based algorithm,and analysed the Qos characteristics of both algorithms.The simulation experiment shows that though there is little difference between the utilization rates of the two bandwidth algorithms,service-based algorithm improves notably the performance of the Qos of the service which provides most profits.
