Research on Congestion Control Method to Speed-up Parallel Transfer in GridFTP

Abstract (in Japanese) (See Japanese page) 
(in English) GridFTP protocol that enables safe and efficient data transfer is proposed, and used in Grid environment. The feature of GridFTP is parallel data transfer. TCP Reno is the typical transport protocol used in GridFTP. TCP Reno uses a loss-based congestion control technique to detect which detects congestion by packet loss and controls packet transmission. TCP Reno has the problem that it cannot fully utilize available bandwidth in broadband and high-latency networks, however. On the other hand, TCP Westwood adopts delay-based congestion control technique that measures round-trip time (RTT), estimates bandwidth usage from its variation, and adjusts congestion window size accordingly. Since TCP controls packet flow individually for each end-to-end connection, it is not optimal to be used in the parallel data transmission of GridFTP which establishes multiple TCP connections between one set of source and destination nodes. In this paper, we propose GridFTP with modified TCP Westwood, but not TCP Reno. Furthermore, we compare existing GridFTP and proposal, and show that the proposal can get high throughput by using the technique.
