中文摘要：

无线局域网分布式接入协议（DCF）是＂通信网络＂课程教学的重点。本文提出的教学设计采用理论分析与仿真验证相结合的方法,深入讲解无线局域网DCF协议饱和吞吐量的二维马尔可夫链模型,并通过模型的局限性分析启发学生的创新思维。本文对无线局域网DCF协议的教学有一定的指导作用。

英文摘要：

The distributed coordination function（DCF）of wireless local area networks（WLANs）is an essential part of teaching communication networks. This paper designs a teaching session of modeling the saturation through-put of the DCF protocol by Markov chain in WLANs. By analyzing the limitations of the model,we effectively in-spire the students of innovation thinking. This paper can serve as a significant guide in the teaching of the DCF pro-tocol in WLANs.
