DEVICE AND METHOD FOR PUBLICATION AND SUBSCRIPTION DATA PROCESSING AND COMPUTER PROGRAM PRODUCT

摘要

PROBLEM TO BE SOLVED: To efficiently use usable resources by allowing a distributing means to make a reservation by a publication-side distribution agent data processing unit and perform reception by a subscription-side distribution agent data processing unit or a subscriber application. SOLUTION: When a publisher 11 publishes a stock market message to a stream stock, the publisher 11 generates an RPC(remote procedure) call to the route distribution agent 21 of the highest level of broker tree structure. By this RPC call, a subscription request for the stream stock by a subscriber 32 is shown through the leaflet distribution agent of the lowest level. Namely, the data message of the publisher 11 is transmitted to the subscriber 32 through a downstream route distribution agent 21, and then an arbitrary intermediate distribution agent 22 and a leaflet distribution agent 24.
