基于TCP／IP协议的网络教学系统设计

通过对高校网络教学现状的调查与分析，提出了总体的设计目标以及设计方案，包括系统运行环境以及系统展现内容．系统采用C／S模式，通过主机与客户机发送数据包，利用网络包截获的相应技术以及包过滤等策略，对特定的数据包进行分析，将各类协议首部用的二进制代码展现，可更直观的看到网络传输的具体方式，同时可将二进制代码转换为十进制，使系统具有更强的可视性．

Design of the Network Teaching System Based on TCP/IP Protocol

Through the survey and analysis of the network-based teaching in colleges and universities, puts forward the overall design purpose and the design scheme including operating environment and the system display content. The system is of Client/Server mode, which analyzes specific data packet by using host PC and client PC to send data packet and using the technology intercepted by network packets and packet filtering strategy, and uses the binary code to display the different network protocols. Thus, the concrete ways of the network transmission can be seen more directly. Meanwhile, the change of binary code into decimal code makes the system more visible.
