The present invention proposes a technique for establishing peer-to-peer multimedia interactions and data exchanges via a discovery mechanism which relies on a model of (chained) programmable switchboards which may be implemented to enable a step-by-step discovery process until the endpoint of the communication chain is actually reached. The novelty of the proposed system and distinct contrast to known systems is that each endpoint can actually program if, how and when it wants to be reached for each individual user initiating contact, and to provide the information on how to be reached to its potential users initiating contact along its own model.

Distributed programmable connection method to establish peer-to-peer multimedia interactions

The present invention describes a method and system for achieving high availability in a networked computer system. In particular, the method for achieving high-availability is executed in a networked computer system. The networked computer system includes nodes connected by a network. The method includes using high-availability-aware components to represent hardware and software in the networked computer system, managing the components to achieve a desired level of redundancy, and monitoring health of the networked computer system, including health of components and nodes. The method further includes detecting a failure in the networked computer system. Failures detected by the method include failures of a component and/or node. Finally, the method includes recovering from the failure by performing an appropriate failure recovery procedure.
