Abstract: 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.

Abstract: Configuring software for a target comprises preparing a command file which specifies a subset of components selected from a group of components, and parameters for tuning at least some of the selected subset of components. The command file is written using a single programming language, capable of managing tree structures of objects, preferably an XML type language, having a Document Type Definition enabling it to work as a programming language. An image file is prepared from the command file, to be loaded on the target.

Abstract: 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.

Abstract: Embodiments of the present invention provide a system and method of modeling a computer system. The computer system is modeled by a plurality of components and a plurality of interface enabling interactions between the components. A searchable tree data structure defining the components and the interactions between the components is generated and stored. The searchable tree data structure may be utilized to determine a status of a particular component. Based upon the status of the component, one or more interactions between the component and another may be enabled.

The computer system is modeled by a plurality of components and a plurality of interface enabling interactions between the components. A searchable tree data structure defining the components and the interactions between the components is generated. The method of modeling the computer system further comprises qualifying the searchable tree data structure as defining valid combination of the components.

Abstract: Configuring software for a target comprises preparing a command file which specifies a subset of components selected from a group of components, and parameters for tuning at least some of the selected subset of components. The command file is written using a single object-oriented programming language, capable of managing tree structures of objects, preferably an XML type language, having a Document Type Definition enabling it to work as a programming language. An image file is prepared from the command file, to be loaded on the target.
