PROBLEM TO BE SOLVED: To provide a cluster system that enables updating by suspending an old signal processor after a certain period of time even if a session continues for a long term.SOLUTION: Signal processors (new) 30B and signal processors (old) 30A-1 to 30A-n in a cluster system 1 respectively comprise a data storage section 32 for storing a combination of session information and state information that relate to a signal. Furthermore, the signal processors (new) 30B-1 to 30B-n respectively comprise an acquisition determination section 37 for determining from which to acquire the state information, and the signal processors (old) respectively comprise a data acquisition IF 36 for transmitting the combination of the session information and the state information to a sorting device 20. The sorting device 20 comprises: a signal sorting section 21 for sorting the signal on the basis of version information and session information for the accepted signal; and an old storage destination acquisition IF 24 for, when receiving the session information, transmitting information showing any one of the signal processors (old), as a reply. |
