Abstract: An application programming interface (API) is described that allows creating or destroying one or more pairs of data structures for asynchronously passing between the operating system and a network application pointers to packet buffers mapped to both parties.

Abstract: A real-time event processing system (EPS) for processing a sequence of events generated by one or more applications. In an illustrative embodiment, the EPS includes a set of real-time analysis engines (RAEs) operating in parallel, e.g., a set of clusters each including one or more RAEs, and one or more mappers for mapping a given input event to a particular one of the clusters. A main-memory database system is coupled to the RAEs, and the RAEs process events associated with input streams from one or more data sources and deliver output streams to one or more data sinks. The data source and data sinks may be, e.g., network elements, clients, databases, etc. The events are processed in accordance with services implemented in the RAEs, and utilize data stored in a memory portion of the main-memory database system accessible to the RAEs. The data may include, e.g., a subscription table storing subscription information indicating the service or services that should be executed for a given event.
