摘要
计算机网络课程的基本概念以及技术涉及到许多抽象的理论知识和大量的网络协议,使许多初学者感到抽象难懂。为此在PXA255 Xscale架构的处理器和嵌入式Linux操作系统的基础上,构建一个干净环境下的网络协议仿真实验系统,排除了其它网络封包的干扰,模拟真实的计算机网络行为,用于TCP/IP协议簇的仿真教学,让学生更好地理解网络协议交互的各个步骤以及相关协议的通信机制。
The basic concepts and technologies of computer network courses refer to numerous Abstract theories and a mass of network protocols,which makes the beginners hard to understand.Therefore,a network protocol simulation experiment system is constructed in an undisturbed environment for simulative teaching of TCP/IP protocols based on the PXA255 Xscale processor and the embedded Linux operating system,in which the interferences of other network packets are eliminated,the real actions of computer network can be simulated.It enables the students to better understand each step of network protocols＇ interaction and the communication mechanisms of correlative protocols.
