中文摘要：

TCP/IP协议簇是网络数据通信中使用的主要协议。网络协议仿真系统为教学提供了一个良好的实验平台,然而目前所用的协议仿真实验系统都是离散的、静态的,即单独模拟一个协议,且协议中的数据表示是静态的,不能随着输入数据的变化而动态变化。为了帮助学生更好地理解以太网中数据通信过程,有必要开发出一个既能使协议之间相互协作,又能动态实现数据的变化,使实验效果逼真实际的仿真实验系统。文中主要描述了以太网动态仿真实验系统混合体系结构的设计和实现,满足了系统的设计需要,提高了系统效率。

英文摘要：

TCP/IP is the most protocol in network data traffic.A good experiment system is presented for teaching by network protocol simulation system,but network protocol simulation system is discrete and static now,one protocol is simulated singleness.The data can＇t dynamic variety with input data because the data is static in the protocol.A simulation experiment system must be implemented for the students to understand data traffic in Ethernet,which can collaboration,and dynamic.The design and implementation of the Ethernet hybrid architecture are described in this paper for the dynamic simulation system,meeting the needs of the system,improving the efficiency of the system.
