Improvement of Efficiency and Comparing Methods of Discovering a Relay Node of a Long-Distance Data Transfer with TCP Using a Relay Node
Hirokazu Kobayashi (IBM Japan), Masaya Nakayama (Univ. of Tokyo) IA2007-4
Abstract (in Japanese) (See Japanese page) 
(in English) It is known that available bandwidth between two nodes whose RTT is large and using TCP is lower than link-bandwidth by bandwidth-delay law.
In this paper, we propose a transfer method that uses a relay node to split RTT virtually and improves throughput.
We show that proposed method can improve throughtput in the surroundings that RTT is more than 100ms between two nodes comparing with direct transfer.
We also propose two method to select a relay node, one uses ping command and other uses traceroute command and show that the former is more effective than the latter.
