Abstract:
1. A relay device comprising: a buffer configured to store a received frame; and one or more processors configured to: discard the received frame, when a utilization amount of the buffer exceeds a first value set corresponding to a communication type of the received frame; calculate the utilization amount for each communication type of the received frame stored in the buffer at least two points in time, and calculate an amount of change in the utilization amount for each communication type of the received frame stored in the buffer; calculate the first value for each communication type based on the amount of change in the utilization amount for each communication type of the received frame stored in the buffer, and set the first value; calculate a second value smaller than the first value previously set corresponding to the communication type in a case that the utilization amount of the buffer increases in the communication type, and set the second value; and calculate a third value equal to or greater than the first value previously set corresponding to the communication type in a case that the utilization amount of the buffer decreases in the communication type, and set the third value.
