摘　　要：TCP/IP是典型的网络分层协议,但是因为TCP/IP的协议基本是处于相关操作系统的内核中,因此对于分层协议实际工作策略掌握起来难度较大。通过IP报文在Linux的内核中进行重组与分段过程,可以在相关应用层对分层协议进行定义,同时UDP在用户的状态下使用套接字能够将应用层的消息重组与分段实现。这个模拟既清楚展示IP重组与分段过程关键处理的活动,又将分层协议整个处理过程直观的呈现出来,适用于计算机网络协议相关教学活动效果比较好。文章就网络协议应用消息重组与分段场景进行分析,探讨分层协议栈的设计,进而模拟应用层消息程序与分段,探讨网络协议分层的实例教学。TCP/IP is a typical network layer protocol,because of the TCP/IP protocol is basic in the related operating system ker-nel,so for layered protocol working strategy it is difficult.Via IP packet in the Linux kernel to restructure and the segmentation process,can be defined in the related application layer to the layered protocol,UDP is used below the condition that the user at the same time the socket restructuring and piecewise implementation to application layer.This simulation program is IP restruc-turing and clear segmentation process key processing activities,and layered protocol the entire process intuitive,this method used in computer network protocol related teaching effect is better.In this paper,the network application protocol messages re-structuring and segmented scenario analysis,Discuss the instance teaching method of network protocol layering.
