Abstract
PURPOSE: To prevent the discontinuity of the processing of the whole system due to the fault of some equipment by enabling both computers to attain access all the time and to back up each other by shifting load distribution.
CONSTITUTION: Information from a communication terminal 4 enters multiplex circuit switching selectors 32A1W32N1, and 32A2W32N2 via a branching device 33. According to the branching of the device 33, the devices 32 pair up like 32A1 and 32A1W32N1 and 32N1, and when one selector selects some circuit, the other selector searches for the other first-coming circuit to select and connect a circuit with the oldest request. Communication controllers 31A1W31N1, and 31A2W32N2 control transmission to and reception from terminals on the circuits selected by the selectors and are connected to intermediate computers 21A and 21B. The intermediate computers operate in load-division mode according to a time series to be connected to host computers 11A and 11B via the communication controllers 23AW23D and 13AW13D. Both the host computers process the same information in parallel, causing no discontinuity of processing because no switching operation is done.
