We have studied a client/server system for editing TV programs via a computer network. Clients' requests for transfer are measured, and modeling is done to estimate the traffic for which to occur on the network. The probability density functions of the periods of data transfer activity and inactivity for these models are approximated by a sum of exponential functions. We discuss the transfer method which TCP and UDP are switched adaptively to deal with these traffic efficiently. The amount of the network traffic at a single bottleneck model is calculated by using TCP, UDP and the above method. The proposed transfer method shows that it is excellent in comparison with the other methods.
