On April 14, 2004, SUNET transferred around 840 Gigabytes of data in less than 30 minutes, using a single TCP stream between one host at the Luleå University of Technology (LTU) in Sweden (close to the Arctic circle), and one host connected to a Sprint PoP in San Jose, CA, USA. The network path used is the GigaSunet backbone - shared with other users of the Swedish universites, and the SprintLink core network, used by all the customers of Sprintlink.


Results:

According to the Internet2 LSR contest rule #5A, IPv4 TCP single stream, we acheived the following results, using a publically available snapshot of the upcoming version of the 2.0 version of the NetBSD operating system, and using a MTU of 4470 bytes:

838860800000 bytes in 1588 real seconds = 4226 Mbit/sec
