Abstract

We advocate the use of publish/subscribe as an interaction style for upgradeable component-based systems. We present an architecture based on publish/subscribe that enables easy dynamic replacement of components. We describe the rationale behind designdecisions relating to robustness, binding, upgrading and transfer of state. Furthermore, we illustrate our architecture using some scenarios.
