Architecture description language based on software reliability evaluation for distributed computing system

For the purpose of high reliability and low cost when distributed computing system is developed, an architecture description language based on software reliability evaluation for distributed computing systems (REAL) is proposed in this paper. Its main purpose is used to describe the software architecture of distributed computing system in order to evaluation reliability of a given architecture. It focuses on the relationship among software architecture, reliability description and evaluation of components and sub-architecture in distributed computing systems. Then a support tool, REAL-Editor is designed. It is composed of such subsystems as language editor, grammar interpreter, and reliability evaluator etc. REAL-Editor supports not only the description of a given software architecture for distributed computing system but also automated evaluating the architecture reliability of distributed computing system. Finally, the tool is tested successfully through an example.
