On the event coordination in multi-component systems

Abstract

In this paper we highlight some issues on the event consistencyinmulti-componentsystemsandthecoordination activities necessary to maintain it. We point out that the generation of events of a component should change with respect to its usage context but the burden of the coordination which maintains such a consistency is entrusted to the developer's cleverness because existing tools do not offer adequate solutions. Hence we present a model of the coordination activities in multi-component systems in order to clarify the space of the problem and possible points where to intervene. Then we propose a conceptual solution based on a set of types of abstract observers through which realizing the above mentioned coordination activities.

An Agent-Based Software Framework for Robotics and Automation Systems

“…This is a characteristic of the architectural style of an application, and it can be implemented adopting two approaches (Moro & Natali, 2002): request/response and publish/subscribe. The request/response paradigm, is widely adopted in traditional client/server distributed systems such as Web-based applications.…”
