With the rapid progress of network technology, over- 10Gbps domestic backbone network is ready to use, and Gigabit Ethernet is now quite common in ordinary environment. On the other hand, it is well known that current congestion control mechanism of TCP/IP doesn't fit well to the network with long latency and wide bandwidth, called Long Fat Pipe Network (LFN). This paper shows the observation on TCP/IP 7500-mile data transfer between Maryland and Tokyo, where the bottleneck is OC-12 APAN line. Surprisingly, throughput of Fast Ethernet is sometimes much faster than Gigabit Ethernet whose throughput is very unstable.
