Abstract: Dynamic software architecture is one of the important research subjects in software architecture. This paper discussed issues in modeling and analyzing dynamic software architectures, proposed a modeling method of dynamic software architectures based on π-calculus, and developed an algorithm for reasoning about the semantics of dynamic architectural configuration. The π-calculus based modeling method is able to specify many aspects of dynamic architecture,including cause,time,operations and non-instantaneous change,etc.

Key words: Software architecture,Dynamic software architecture,Architecture description language,π-calculus
