<p>PROBLEM TO BE SOLVED: To automatically determine an appropriate communication parameter in a network system including one or more relay devices.SOLUTION: A predetermined node 60 includes a delay time measurement unit 61 for measuring and storing a transmission delay time which is a time related to data transmission between the predetermined node 60 and each other node. A delay time acquisition unit 51 acquires a measured value of the transmission delay time from the predetermined node 60. A data amount set unit 52 sets a data amount related to data transmission. Based on the transmission delay time and the data amount, a communication cycle calculation unit 53 obtains a communication cycle as a network parameter.</p> |
