ABSTRACT:
A device for discriminating timeout comprises an event discrimination unit, a calculation unit, a timing storage unit and a timeout discrimination unit. The event discrimination unit outputs each communication information concerning each communication to the calculation unit, when an event indicating a start of timeout discrimination occurred. The calculation unit calculates a timeout timing for every communication on the basis of the each communication information and the timing in which the event has occurred, and writes the calculated timeout timing into the timing storage unit. The timeout discrimination unit compares the timeout timing read out from the timing storage unit for every communication with the present timing, and discriminates that the timeout has occurred in reference to the communication when the present timing exceeds the timeout timing.
