Abstract
In a network system in which a large number of terminals that transmit information exist and data extraction is performed via a wide area network, when data filtering is performed by using terminals called entrance nodes, existing in front of the wide area network, efficient operation of the entrance nodes is a goal to achieve. In one implementation, when an entrance node has detected an alteration to a configuration of diverse resources attached to it, it updates management information by communicating with other entrance nodes existing in the neighborhood. In a further implementation, through a query and reply exchange about allocations of filtering and quick response processes to be executed by entrance nodes, reallocating process items, pre-filtering of necessary data, and relaying data between entrance nodes are performed.
