摘 要:随着接入网络作为连接用户终端与核心网络的纽带的倍受关注,用户越来越关注数据传输的QoS(服务质量)问题:在IEEE802.16协议的MAC层定义了比较完善的QoS机制。但QoS机制中的核心问题,带宽调度算法,协议没有作出明确的阐述和定义:该文在已有典型算法基础上,吸收、采纳了已有算法中适合于1EEE802./6协议的带宽调度的方法,并结合IEEE802.16协议关于QoS的定义,提出了一个针对IEEE802.16协议的PMP(点对多点)模式下集中式的带宽分配调度算法:并在NS2模拟环境下对算法进行了测试。With the close attention of access network as the connectivity of the user ternainal and the core network, customers pay more attention to the QoS (quality of service) issues of the data transmission. In the IEEE802.16 protocol, the MAC layer has defined a relatively perfect QoS mechanism. But the Bandwidth Scheduling Algorithm, the core problem of the QoS mechanism, the protocol has not clear definition. Based on the typical algorithm, the paper absorbs and adopts the bandwidth scheduling method fit for the IEEE802.16 protocol in the typical algorithm, and with the definition of the QoS in the IEEE802.16 protocol, puts forward a centralized bandwidth scheduling algorithm in the mode of the PMP to the IEEE802.16 protocol And it has tested the algorithm in the NS2 simulated environment.
