一种基于协议组合的协议动态实现模型

A Dynamic Protocol Implementation Model Based on Protocol Composition

在协议组合理论的基础上提出了一种可以动态扩展协议句法的基本协议实现模型,依据现有协议特征中的句法结构,将协议句法结构划分为4个不同的种类,针对这4种不同类型的协议句法结构具体提出了4种不同的可动态扩展的协议句法实现模型。基于该模型实现的协议软件在句法结构上具有灵活可扩展的特性。当该协议扩展句法结构时候,即使相应协议软件处于执行状态,也可以不中止协议软件的运行而完成句法结构的扩展。最后以SIP协议为例,使用VOCAL源码详细说明了如何在该模型的基础上实现协议句法动态扩展。

A protocol implementation model with dynamically exlendible syntax is proposed based on protocol composition. The structure of protocol syntax is divided into four categories according to the existing protocol features,and correspondingly,four different dynamic ally extendible protocol syntax implementation models are proposed. The software implementation based on the model is flexible and extensible in syntax structure. Using this model the syntax structure can be extended without stopping protocol services. Taking SIP for example, this paper explains how to use this model to implement dynamic extension of protocol syntax based on VOCAL.
