摘　　要：基于无线基站进行高速分组交换时,采用有良好公平性及时延保证的调度算法对实现区分服务网中每跳转发技术至关重要,提出了一种两层结构的应用于区分服务无线接入网的无线分组调度算法,该算法能很好地满足区分服务结构下各类业务的服务质量要求.理论分析和仿真表明,当无线链路突发错误时,该算法能提供较好的时延性能和短期公平性.It is important of implementing the PHB (perhop behavior) technique of the differentiated service network to adopt a scheduling algorithm with good delay and fairness performances in high rate packet transference of wireless base stations. A wireless packet scheduling algorithm of two hierarchy was proposed to be employed in the wireless access network based on differentiated service. It can well satisfy the QoS demand of different services in differentiated service architecture. The theoretic analysis and computer simulation show that this algorithm has good delay performance and shortterm fairness.
