NetBSD Sets Internet2 Land Speed World Record

Daniel de Kok writes "Researchers of the Swedish University Network (SUNET) have beaten the Internet2 Land Speed Record using two Dell 2650 machines with single 2GHz CPUs running NetBSD 2.0 Beta. SUNET has transferred around 840 GigaBytes of data in less than 30 minutes, using a single IPv4 TCP stream, between a host at the Luleå University of Technology and a host connected to a Sprint PoP in San Jose, CA, USA. The achieved speed was 69.073 Petabit-meters/second. According to the research team, NetBSD was chosen 'due to the scalability of the TCP code.'"

Did they check for any inband compression? They data they're sending isn't randomised.

466 MB/s

840GB/30 minutes = 466 MB/s, or 3,728 Mbps

Can we get a Uhaul trailer?

That depends on whether the DVDs are in cases or not I think.

At 9.4 GB per DVD (Assume single-layer double-sided DVD-R), and a travel time of 3 weeks from Sweeden to California (2 weeks on the boat, one week of driving), you'd need to get about 90,000 DVDs in your station wagon to get an effective 1680 GB/hr. That wouldn't be possible if they were in cases, but if it was just the DVDs, it's probably a close call. Might have to upgrade to dual-layer DVD's, or change the saying to "an SUV full of DVD's".

On the other hand, if you count the time to actually read the data off of the DVDs (even worse if you count the time to put the data on the DVDs too), the station wagon of DVD's barrier was broken long ago - you probably couldn't spin a DVD fast enough to get 9.4 GB of data off it in 20 seconds.

Man I hate to be on the recieving end of a Denial of Service attack on Internet 2. 900 gigabytes of data /30 min from multiple sourses would be crushing.
