Detection of variations in a large quantity of sensing data connected to a network and prescribed processing corresponding to the variations are to be executed at high speed. An event-action controller for monitoring data collected from plural sensors and executing preset processing when the data has come to satisfy preset conditions includes an event-action entry search engine, an event-action table, a cache and a cache controller. The cache controller further includes a learning table for learning an arrival cycle of sensing data, a learning table controller, a cache access controller, a forwarding controller and time information.
