摘要
本文针对现有通信网实验教学中存在的问题,提出在通信网络教学和实验中结合使用OPNET网络仿真软件,使学生可更容易理解和比较相关协议、设备和网络的性能比较。最后以一综合设计型实验为例,从网络拓扑、体系结构、网络协议和性能分析等方面对DCF和PCF机制进行仿真。
According to the problem existing in the experimental teaching of communication networks, such as the course was abstract, difficult and complex, and communication networks technology developed quickly, however the laboratory equipment updated obsolete. Network simulation software OPNET is proposed to adopt in both the teaching and experiments. The students can more easily understand and compare related protocol, equipment and networks performance comparison. As an example. The DCF and PCF mechanisms of WLAN are analyzed and simulated from the aspects of network topology, architecture, and network protocols and so on.
