Abstract
A network system has a plurality of nodes interconnected to each other for transferring a data packet from a transmitting node to receiving nodes so as to concurrently drive the same. In the transmitting node, an estimating device estimates a time lag which exists between the transmitting node and each of the receiving nodes and which varies among the receiving nodes. A determining device detects a maximum one of the estimated time lags so as to set a reference time by which all of the receiving nodes can be synchronized with each other. A transmitting device transmits a data packet to the receiving nodes together with the reference time stamped on the data packet. In each of the receiving nodes, a receiving device receives the data packet together with the stamped reference time. An adjustment device temporarily retains the received data packet for adjusting the difference in the time lags among the receiving nodes according to the reference time so that all of the receiving nodes can be driven concurrently with each other.
