Generic Middleware Substrate through

Abstract. Conventional middleware architectures suffer from insufficient module-level reusability and the ability to adapt in face of functionality evolution and diversification. To overcome these deficiencies, we propose the Modelware methodology adopting the Model Driven Architecture (MDA) approach and aspect oriented programming (AOP). We advocate the use of models and views to separate intrinsic functionalities of middleware from extrinsic ones. This separation effectively lowers the concern density per component and fosters the coherence and the reuse of the components of middleware architectures. Comparing to the conventionally designed version, Modelware improves the standard benchmark performance by as much as 40 % through architectural optimizations. Our evaluation also shows that Modelware considerably reduces coding efforts in supporting the funcitonal evolution of middleware and dramatically different application domains.
