基于协议引擎的协议实现方法研究

为了从实现的角度解决网络协议相似性和多样性的矛盾，以及不同协议不同实现方法对系统资源的消耗和协议管理维护的复杂性问题，文中在分析了基于ＯＳＩ协议实现的基本问题的基础上，提出用面向对象方法和虚拟概念解决通用性难题，并且提出了基于协议引擎的协议实现方法，分析了它的结构特点和应用时的几点考虑，认为效率是主要评价因素，文中还给出了Ｊａｖａ环境上应用协议引擎网络管理模块和网关路由器的实现方案。

RESEARCH ON A PROTOCOL IMPLEMENTATION METHOD BASED ON PROTOCOL ENGINE

In order to solve the paradox between similarity and diversity of network protocols, the cost of system resources for different protocols and different implementation methods, and the complexity of management and maintenance of protocols, realization of the generality by using object oriented methods and concept of virtual machine is proposed,a protocol implementation method based on protocol engine is given, and its structural character and some considerations in application are analysed,based on the analysis of basic subjects in OSI protocol implementation. Efficiency is regarded as the main evaluation factor. Also given are implementation schemes of the network management module and gateway router while applying protocol engine in the Java environment.
