Experimental Results of TCP / IP data transfer On 10 Gbps IPv 6 Network

It is well known that TCP/IP data transfer on LFN (Long Fat pipe Network) is difficult, and this problem has become more serious as the bandwidth grows. Especially single stream TCP is the base of all the internet high speed communication and the key of scientific data transfer system such as Data Grid. We show the performance and behavior of single stream TCP at LFN, both on pseudo and real 10Gbps network. Pseudo network by network emulator makes a long latency almost around the world. We analyzed and compared real network with pseudo LFN network, and we tried LSR (Internet2 Land Speed Record) of single stream IPv6. This paper describes the detail of experimental results of single stream TCP data transfer on LFN with 10Gbps speed, using both IPv4 and IPv6 by standard/jumbo frame 10Gbps Ethernet.
