A data acquisition, DAQ, system with using the Internet technology is used in many fields these days. But the Internet is a general purpose technology and suitable to transfer data randomly. Moreover, as a lot of clients and servers are connected into the Internet, the network topology of it is N to M, i.e., the N source computers are connected into the M destination ones. On the other hand, the topology of DAQ systems is based on N to 1, because a measurement is performed with using several detectors and their data have to be sent to one destination computer to analyze them. The Internet technology is not efficient for transferring in N to 1, and such traffic occurs congestion in the network. We, therefore, focus on congestion control mechanisms in the TCP protocol to avoid the congestion and propose the efficient mechanism for a large-scale DAQ system.
