Abstract: To improve usability and a processing speed by waiting for a string of information associated with each other, and appropriately aggregating data satisfying a specific condition when outputting the data, and retaining and storing the aggregated data. In a case where a string of information originally associated with each other is arrival, separately, a data input/output unit determines a processing pattern on the basis of information on an input source. A data processing unit implements a processing condition for waiting for the associated information, individually, controls the storage of data in conformity with the processing condition, and aggregates and retains the string of data, and outputs an aggregation result. Also, the data processing unit can delete the string of unnecessary data in a lump.

Abstract: In a processing system including a data distribution server and multiple processing servers, the data distribution server transfers data to any one of the multiple processing servers, and the processing server includes a server determination information storage unit in which load information on each of the multiple processing servers is stored and an application specific transfer determination information storage unit in which a condition to be transferred peculiar to an application is stored. A processing server in question generates a message upon determining to have received data including information identifying the application, identifies the application upon determining to have received the message, selects any processing server based on the information stored in the server determination information storage unit and the application specific transfer determination information storage unit, and executes the application or transfers the message to the selected processing server according to the selected processing server.

Abstract: It is provided a computer system, comprising a plurality of computers configured to execute processing in response to requests received from a plurality of external systems. The plurality of computers each share an acceptance weight statistic value calculated by each of the plurality of computers with another computer within the same network segment. The processor of each of the plurality of computers is configured to: receive a broadcast transmitted from one of the plurality of external systems to the same network segment; determine whether to respond to the received broadcast by referring to the shared acceptance weight statistic value; and send a response to the one of the plurality of external systems that has transmitted the broadcast in order to allow the one of the plurality of external systems to transmit a processing request in a case where it is determined to respond to the received broadcast.
