This manuscript was written for ISPAN03. In this paper, we point out a problem of congestion control mechanism of TCP on Long Fat pipe Network (LFN) by precise analysis using our hand-made tools, and we propose "congestion control algorithm for parallel streams" and "packet spacing algorithm in slow start phase" for LFN. This paper presents (1) observation of TCP/IP multi-stream data transfer across 7500 miles, (2) analysis tools for congestion problem; i.e., packet logging tool and pseudo LFN emulator, (3) pseudo LFN experiments and (4) modification of congestion control algorithm, "balancing parallel streams with TCP fairness and TCP compatibility" and "packet spacing".
