协议形式化描述是协议工程的核心,对于协议的开发起到基础作用.首先对协议形式化描述技术进行了综述,然后着重研究了两种协议形式化描述技术:基于CSP的描述和基于RSL的描述,并以AB协议为例,分别给出了具体的描述示例.这两种技术具有较强的表达能力,是进行协议描述的有力工具.
Protocols formal description is the kernel technology of protocol engineering.It is foundation of protocols development.This paper firstly summarizes some current technologies of FDT.Then two technologies are studied:one is CSP(Communicating Sequtential Processes),and another is RSL(RAISE Specification Language).Examples are also presented to show how to use them to describe AB protocol.
