Abstract

Abstract: Based on the analysis of traditional Qos service model and traditional Dynamical Bandwidth Allocation（DBA） method，this article proposes a service-oriented DBA algorithm.This algorithm absorbs various advantages of traditional QoS service model and traditional DBA algorithm，this algorithm fully consider the difference of bandwidth allocation request of different QoS of services and the utility factor of bandwidth resource，the simulation results show that the algorithm is more efficient.

Key words: Dynamic Bandwidth Allocation（DBA）, Quality of Service（QoS）, resource utility factor

摘要： 在分析传统QoS业务模型以及传统动态带宽分配方法（DBA）的基础上，提出一种面向业务的动态带宽分配算法。该算法吸取了各种QoS业务模型及传统动态带宽分配方法的优点，充分考虑了不同业务服务质量对带宽分配要求的差别以及带宽资源的利用率，仿真结果表明这种方法更加有效。

关键词: 动态带宽分配, 服务质量（QoS）, 资源利用率
