分布式实时系统体系结构描述语言的设计及其应用实例研究

Design of Distributed Real-Time System Architecture Description Language and a Case Study of its Application

为了完成基于软件体系结构(SoftwareArchitecture,SA)分布式实时系统的测试,需要设计一种体系结构描述语言(ArchitectureDescriptionLanguage,ADL)描述被测系统,以便自动产生测试用例.在考察现有的体系结构描述语言(Architec-tureDescriptionLanguage,ADL)的基础上,分析了现存ADL的不足,提出了一种新的分布式实时系统体系结构描述语言(Dis-tributedReal-TimeSystemArchitectureDescriptionLanguage,DRTSADL),研究了该语言的语法和操作语义.结合一个分布式实时前端系统实例描述,说明了DRTSADL的应用.与现存ADL相比,新的ADL对分布式实时系统有较强的描述能力.

In order to accomplish distributed real-time system testing based on software architecture, an architecture description language （ADL） needs to be designed to describe the system under testing, so that the architecture description specifications can be used to generate testing cases automatically. On the basis of reviewing existing ADLs and analyzing their inadequacies, a new distributed real-time system architecture description language （DRTSADL） is proposed in this paper, the syntax and operation semantics of DRTSADL are studied. And the application of DRTSADL is illustrated through a distributed real-time front-end system instance description. Compared with the existing ADLs, the new ADL is more effective in describing distributed real-time system.
