We study the qos strategy in wireless networks . after understanding the wireless local network based on ieee 802 . 11 , we point out the problem that occur when a large msdu ( mac service data unit ) is to be sent in the dcf mode in wireless lan . when a msdu is divided into several mpdus ( mac protocol date unit ) , the later mpdu will service as a important role 在此基础上，我们研究了无线局域网中的服务质量策略，在对基于ieee802 . 11的无线局域网进行了充分了解的基础上，提出了在无线局域网dcf方式下发送较大msdu [ 2 ] （ mac层服务数据单元）时会遇到的问题，指出当把msdu分片[ 2 ]成为一组mpdu （ mac层协议数据单元）进行发送时，随着mpdus的不断发送，排序靠后的mpdu将对整个msdu的发送时间产生决定性影响。
