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



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.

Relevant Problems Addressed Padres provides a secure, flexible platform to

integrate and manage distributed real-time information HD8: Provide a rigorous foundation for national

defence and security emerging concepts and doctrine (comprehensive, integrated, adaptive, networked)

HD9: Improve northern and maritime situational awareness and response

HD3: Build an integrated Canadian Forces system
