Abstract
A propagation delay time measuring system 100 includes a propagation delay time measuring apparatus 110 and a reply apparatus 120. The propagation delay time measuring apparatus 110 continuously transmits plural measuring packets a. A clock time of transmission is stored in the measuring packet a. The reply apparatus 120 sends back the measuring packets a, transmitted from the propagation delay time measuring apparatus 110, to the propagation delay time measuring apparatus 110. In the propagation delay time measuring system 100, the propagation delay time measuring apparatus 110 receives the measuring packets a sent back from the reply apparatus 120, and the propagation delay time measuring apparatus 110 measures a propagation delay time between the propagation delay time measuring apparatus 110 and the reply apparatus 120 using at least one of the received measuring packets a.
