A server computer 11 in a data transmission system receives data processing demand packets sent in from any of a plurality of terminal computers on the network via a specific terminal port on the switching hub, and a group of sending data packets is formed against the data processing demand packets and at the same time this sending data packet group is sent, via the specific terminal port, to the terminal computer 12 that sent out the data processing demand packet. The terminal port manager first finds out, on the basis of the information contained in the data processing demand packet, the number of the terminal port on the switching hub 13 to which the terminal computer, the destination of the sending data packet group, is connected; a terminal port number checker then checks the terminal port numbers found out by the terminal port manager if the terminal port numbers for sending data packets formed on the basis of consecutively received processing demand packets are the same; and then an output regulator adjusts the time of sending out the second sending data packet unit for the data processing demand packet if the two consecutive terminal port numbers are found identical by the terminal port checker. This way, the possibility is precluded that there will be a rush of sending data packets to the same terminal port.
