Summary on Grant Application Form |
We will establish a paradigm in which event instances are objects as a basis for building scaleable distributed systems. We will extend an Interface Definition Language to handle event registration and notification. Clients register interest in specified classes of events, and servers then notify them of any occurrence asynchronously. Methods to handle registration and notification are generic and can be inherited by objects of any class: as a by-product of IDL processing the stubs to handle event creation and decoding are generated automatically. Access controls will be extended to restrict event notification. We will design, implement and formalise a prototype composite event recogniser based on finite state machines with multiple activations. An event algebra and associated language will allow clients of the service to indicate composite events to the service. Composite event servers will support registration and notification in a standard way. Detection details for such event occurrences will therefore be transparent to high level clients.
