以太网协议数据封装动态仿真的设计与实现

Design and Implementation for Dynamic Simulation Data Encapsulation of Ethernet Protocol

传统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。文中描述的以太网动态仿真实验系统能够动态地反映以太网数据通信中各协议之间的相互协作过程,可以帮助学生更好地理解以太网中的数据通信过程。数据封装是协议工作的重要阶段,在实验系统中动态、真实再现数据的封装过程,克服了已有协议仿真系统的不足,可以满足场景化实验教学的需要。

Traditional network protocol simulation system is discrete and static now,only one protocol is simulated singleness.The data can＇t be dynamic variety with input data because the data is static in the protocol.The Ethernet dynamic simulation experiment system can image collaboration between protocols at data traffic,and help student to understand data traffic in Ethernet.Data encapsulation is an important phase of protocol,the shortage of the protocol simulation system is overcome by dynamic,real presenting the encapsulation process.It can meet the needs of scene experiment teaching.
