ADEES: An Adaptable and Extensible Event Based Infrastructure

Abstract

This paper describes ADEES, an open and evolutionary event-based architecture to develop complex distributed information systems. Different from most existing event supports that provide limited event description models and fixed management models, ADEES can be extendedandcustomizedon a per-application basis. It is not another “one-size-fits-all” event manager! It is usedto generate event managers adopted by components to produce and consume events according to the event description and event management models they need (e.g. event as anonymous messages, specific composite event operators, synchronous/ asynchronous detection, push/pull protocol).

The second aspect concerns the ability of a event service andev ent managers to reconfigure andad apt themselves with respect to application requirements andto their environment. Adaptability andextensibilit y is achieved, thanks to meta-programming and reflection techniques.
