In this paper, we evaluate TCP performance in the long delya environment which actually recorded:280Mbit/s between APAN Tokyo XP and Osaka University, 224Mbit/s between APAN Tokyo XP and Kyushu University and 193Mbit/s between APAN Tokyo XP and StarLIGHT and evaluation of the reason why some sections are not good performance.
