| 摘 要： | 文章介绍了加权公平排队(WFQ)分组调度算法和IEEE 802 16的QoS架构.在此基础上,文章结合分级WFQ分组调度算法和IEEE 802 16协议中所提供的控制机制提出了一种适合于BWA系统的QoS架构.该架构充分利用IEEE 802.16提供的控制机制,结合分级WFQ公平队列调度算法,在主动授予业务(UGS)、实时轮询业务(rtS)、非实时轮询业务(nrtPS)和尽力传输业务(BE)之间公平分配带宽,并保证各种业务的QoS特性,完成了在IEEE 802 16协议中留给用户自己定义的调度策略.

| Abstract: | The (WFQ) packet scheduling algorithm and the QoS architecture of IEEE 802.16 are introduced. Based on the control mechanism supported by the Hierarchical WFQ packet scheduling algorithm and IEEE 802.16 protocols, a QoS architecture for Broadband Wireless Access Systems (BWA) is proposed. This architecture can make better use of IEEE 802.16 control mechanism and realize fair bandwidth allocation among the Unsolicited grant Service (UGS), Real Time Polling Service (rtPS), non-Real Time Polling Service (nrtPS) and Best Effort (BE) transmission service. It can also guarantee the QoS of various services, thus implementing the scheduling reserved by IEEE 802.16 for users to make specific definitions. |
