| 摘 要： | 在动态带宽分配(dynamic bandwidth allocation,DBA)的研究中,往往对带宽利用率关注较多,但现实是能够支持多业务网络的服务质量(Qos)越来越重要.基于上述情况通过研究提出了新的基于业务的带宽分配方式,和现有的基于节点(ONU based)方式进行对比,分析了两种带宽分配方式的Qos特性.仿真试验表明:两种方式在带宽利用率上差别不大,但ServiceBased方式对主要利润业务的Qos有显著提高.

| 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. |
