摘要： PROBLEM TO BE SOLVED: To suppress fluctuation in a real-time frame by transmitting the real-time frame in a desired timing, without incurring waiting times by a non-real-time frame, when transmitting a frame restricted in time so as to request real-time properties in an apparatus that includes the function of outputting a frame, such as a terminal or a switch. SOLUTION: When a real-time frame, that first arrives at each switch after real-time communication start, is delayed by a non-real-time frame, that real-time frame is discarded. Thus, since proper time can be ensured for the arriving real-time frame, the delivery timing of a real-time frame that arrives next can be calculated accurately, and the non-real-time frame is suppressed, in matching with the calculated timing.
