To deal with emerging network technologies and services, as well as with varying application requirements and dynamic environmental conditions, middleware has to be reconfigurable. This requirement highly affects the middleware communication architecture, which comprises inherent middleware communication mechanisms and the underlying network architecture. In this report, we introduce an architectural model for reconfigurable middleware communication architecture. Towards this objective, our model re-applies application layer semantics to the middleware communication architecture. It specifies a complete interaction and addressing mechanism for middleware communication architecture objects. Further, an incorporated reflection architecture enables dynamic reconfiguration.
