Specifying Dynamic Software Architectures for Distributed Systems

Open and dynamic characteristics of distributed software systems make user requirements and hardware resources change more rapidly, which make their evolution or reconfiguration inevitable, especially during their execution. A critical issue for those distributed systems is the specifying and analysis dynamic reconfiguration process of their architectures. In this paper, we proposed a method of specifying dynamic software architectures for distributed systems. Based on hypergraph, reconfiguration production rules and operations, we can specify dynamic reconfiguration of software architectures for distributed systems. The paper also includes an example which shows how our approach can be applied to specify modeling of dynamic evolving distributed software architectures.
