With advance of high bandwidth backbone networks, it is dramatically increasing to cooperate between the users who are far from each other and make use of bulk data. UDT(UDP based Data Transfer protocol) is a UDP based application level data transfer protocol which designed to guarantee reliability as TCP. Parallel transfer techniques has recently been studied to increase its performance. Here, it is very important issue to decide the number of channels for best performance on a given network environment. In this paper, we propose an optimum channel prediction method for UDT parallel transfer protocol. With experimental examination, we first analyze a correlation between the number of channels and the distance for data transfer. Then a decision model to trace the number of parallel channels is suggested to reflect the trend of network situation variation. With implementing the model, the effectiveness of the suggested model is discussed in detail.
