Abstract :
We point out a problem of the congestion control mechanism of TCP on the long fat pipe network (LFN) by precise analysis using our hand-made tools, and propose a 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.
