准入控制在保证QoS的无线网络教室中的应用

The Application of Access Control in Wireless Network Classroom Assuring QoS

文章研究了无线网络环境的管理和控制,为无线网络教学、视频会议等提供更好的服务。针对无线网络中音视频的特点,提出了在典型的客户机/服务器模式下简单易行的基于测量的准入控制机制。网络中一台客户机对无线网络教室进行监听和对网络负载数据进行测量,通过对网络拥塞状态的分析,准入控制机制对无线网络内的用户数和音视频的质量加以控制,从而有效地提高了无线网络带宽的使用效率。

In this paper,we mainly study the management and control of wireless network environment,which makes a better support for e-learning,video meeting,and so on,which is based on wireless environment.Aiming at the characteristics of real time audio and video in wireless network,this system takes a typical client/server model to monitor the wireless network classroom and collect the data of network status.Through analysis of these data,we implement the QoS of real time audio and video and access control of user,consequently this solution can enhance the utility of wireless network band.
