3. MIDDLEWARE SYSTEMS RESEARCH GROUP Copyright © 2010 - Hans-Arno Jacobsen DRDC-UofT Workshop, 2010 What Event Processing Support is Required ? De-coupled & loosely coupled many-to-many interactions Fine-grained filtering In-network processing Composite event detection and event correlation Event dissemination

4. MIDDLEWARE SYSTEMS RESEARCH GROUP Copyright © 2010 - Hans-Arno Jacobsen DRDC-UofT Workshop, 2010 What Abstractions Enable Event Processing? The afore-mentioned points can best be addressed by  The content-based publish/subscribe model  Realized by content-based message routing Events are conveyed as publications. Event listening, filtering and correlating is based on content-based subscriptions managed by the pub/sub system.
