摘　　要：为了满足计算机网络原理课程实验的需要,本文设计了一种数据链路层协议实验系统.该系统不再要求学生集中上机,可以充分利用学生宿舍的计算机资源进行远程实验.同时实验结果和成绩由系统自动评判,大大减轻了教师的工作量.本实验系统侧重于网络协议设计而不是配置观察,同时对协议实现进行了一定简化和实现细节的封装,这样学生根据提供的函数接口和动态链接库就可以实现数据链路层协议,不仅减少学生不必要的工作量,而且有助于学生对链路层协议设计的主要目标和思想的理解,为更好地开展网络原理实验提供了一种新的模式.Considering the experiment requirement of computer network, a data link layer protocol experimental system was designed in this paper. It was proposed that students do experiments by using their personal computers remotely instead of being in the lab. Meanwhile, the experimental results and grades are judged by the system automatically, which reduced the workload of teachers significantly. Designing network protocol is emphasized in this system but not configuration and observation. Details of protocol implementation were simplified and encapsulated to some extent, so that it was convenient for students to devise some data link layer protocols by using these procedure interfaces and dynamic link library provided by this system, which did not only avoid some unnecessary work but also conduce to comprehending the primary goals and ideas of link layer protocol＇ s design for them. This system provides a new model for better carrying out computer network experiment.
