无线局域网两级循环查询优先级控制系统的应用分析

Application and Analysis of PRI Controlling System of Two-order Circulating Query of Wireless LAN

在具体分析视频业务、语音业务等数据传输业务的基础上,通过两级循环查询多业务优先级控制传输系统的实际应用,并与文献[4]的周期查询限定服务(K=1)系统及周期查询限定服务(K=1)并行调度控制系统进行比较,进一步验证新系统对无线宽带视频等实时业务传输性能的改进。

Comparisons are done on the method of PRI controlling system of two-order circulating query and the polling limited service system （ K = 1 ） and polling limited parallel control service system （ K = 1 ） mentioned in reference 4 of this paper, based on an analysis of video-operation and audio-operation for wireless LAN. The improvement of the new system to the transmission performance of video-operation and other real time operation is further tested.
