Industrial challenges in working with events
P. Dini · 2004
Event-based systems, event-driven management systems, event-based applications, publish/subscribe systems, content-based networking, event-processing, incident handling events, intrusion detection events, application-related events, configuration-change events, and other similar event-based expressions capture so much semantic and complexity that each in turn deserves a special presentation. There is a growing consensus between practitioners and scientists on event taxonomy, event processing operations (filtering, correlating, aggregation, etc.), temporal representation, and the system requirements to receive, subscribe, process, and deliver events. Nonetheless, the hot industrial challenges in management systems to producing, handling and reacting to events are shadowed by very simple problems that are yet unsolved problems across the industry. These problems are in the definition, interoperability, and implementation. This talk will briefly illustrate several angles of current concerns, through use cases covering device instrumentation, network protocols, domain-oriented application, and management applications. The declared target is to identify challenges and raise appropriate questions, open to a large debate. Some issues may have immediate and simple solutions: others may be simply postponed, due to the lack of feasible and testable solutions.
