DISTRIBUTED PROCESSING USING CONVEX BOUNDING FUNCTIONS

摘要

According to some embodiments of the present invention there is provided a computerized device for monitoring of distributed data streams comprising a network interface adapted to send processor instructions to processing nodes. The device comprises a central processor adapted to provide a non-convex function for centralized monitoring of two or more data streams from the processing nodes and compute new processor instructions defining a convex function greater than or equal to the non-convex function over a limited domain. The central processor is adapted to send the new processor instructions to the processing nodes that locally receive at least one data stream and execute the new processor instructions on a local processors.;The local processor analyzes the convex function applied to the locally received data streams and forwards an outcome of the analysis to a centralized monitoring unit when the output value complies with a local predetermined criterion.
