DATA PROCESSING DEVICE, METHOD, AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To prevent all data processing programs from automatically concentrating on a buffer device in which a congestion state occurs.SOLUTION: When congestion occurs in a buffer device, a data processing device inhibits all data processing programs from concentrating on the buffer device in which the congestion occurs by mixing data processing programs that operates according to a rule to preferentially select the buffer device in which the congestion occurs and data processing programs that operates according to a rule to select buffer devices in the same order as before even when congestion occurs.
