介绍了ADL,它是一种基于网络实时系统的活动性描述语言,一种描述并发处理中时态和功能行为的新的形式规格说明符号。ADL专用于计算机网络,是DORIS的一种形式语言扩充。它组合了状态机活动(ASM)的图形符号和基于模型的活动功能行为(AFB)符号;提供了关于ASM的抽象语法和静态、动态语义。最后通过一个小实例说明该语言是如何解释指定网络实时系统的。
This paper presented ADL that it is an activity description language for real-time networks, a new formal notation for the specification of the temporal and functional behaviour of concurrent processes. ADL is used to specify a computer network. DORIS were extended with the formal language. It combines a graphical Activity State-Machine(ASM) notation and a model-based Activity Functional Behaviour(AFB) notation. The abstract syntax and static and dynamic semantics for the ASM notation are given. This paper illustrsted how an ADL specified real-time system by a small case study.
