Abstract
A transmission device transmits a frame to a correspondent device and receives a frame from the correspondent device. The transmission device includes: a measurement unit configured to perform a delay measurement that measures a period of time from when a frame is transmitted to the correspondent device until when a corresponding frame is received from the correspondent device; and a delay decision unit configured to determine a transmission delay between the transmission device and the correspondent device based on a plurality of target measurement results obtained from a plurality of delay measurements except for at least a first delay measurement among delay measurements performed by the measurement unit.
