| Abstract(in English) | Recently, in Grid environment, high performance data transfer services, such as Long-distance High-speed transfer is needed. However, it was reported that TCP cannot achive high throughput in LFN. As one of the solution overcome that, UDT which has rate control and adds reliability based on UDP is proposed. But, performance of UDT has not been fully investigated on LFN. In this paper, we first investigate basic performance of UDT through simulation. when multiple UDT flows coexist in LFN, they cannot perform suitable rate control and caused a lot of packet loss, because end nodes due to overestimates bandwidth each other. Furthermore, we propose a new novel control method combined two approaches to solve those problem. One is a new bandwidth estimation approach. another is packet drop strategy in RED based on real queue size to prevent from bursty packet loss. The simulation results shows that proposed method can improve loss probablity with keeping high throughput. |
