<P>PROBLEM TO BE SOLVED: To centralize processing of events whose status needs to be shared in the same node and distribute processing of events whose status does not need to be shared, when decentralized processing is performed on context calculation by a plurality of nodes. <P>SOLUTION: The system includes: a rule interpretation unit 5 that extracts a hash calculation key for determining a context calculation node 2, which is a destination of distribution of events, by analyzing a context calculation rule, and a match rule for determining the context calculation rule to be applied to the events; and an event distribution unit 9 that determines the context calculation node 2 which is the destination of distribution on the basis of the hash calculation key and transmits an ID of the calculation rule corresponding to the event and the match rule to the context calculation node 2, the hash calculation key being an element of an event used by the context calculation rule as an unit of calculation, and the match rule being an attribute of an event referred to in the calculation rule. <P>COPYRIGHT: (C)2012,JPO&INPIT |
