“Researchers in South Korea have built a networking router that transmits data at record speeds from components found in most high-end desktop computers. A team from the Korea Advanced Institute of Science and Technology created the router, which transmits data at nearly 40 gigabytes per second–many times faster than the previous record for such a device.”
The better the routing capacity, the better off we all will be. Some of the comments on the article are interesting. I hadn’t thought about power consumption…

I’ve love to know more about how they went about this; how many CPUs, memory…?
GPU.
Other details aren’t mentioned.

The goal is to use a standard PC with some 10Gb/s network cards as a cheap router for small organizations.
People building larger scale networks use different hardware. It is not that this development will make our ISP connection faster.
Quick google search returned this:
http://www.juniper.net/us/en/local/pdf/datasheets/1000051-en.pdf
Juniper’s (which is only one of several core router suppliers) fastest router has throughput of 1.6Tb/s. It has quite a few 10Gb/s, some 40 and 100Gb/s optical interfaces. If that’s not enough you can get a matrix of 16 of them with a total throughput of 25.6 Tb/s.
“. Commercial software routers from companies such as Vyatta can typically only attain transfer data at speeds of up to three gigabytes per second. That isn’t fast enough to take advantage of the full speed of a typical network card, which operates at 10 gigabytes per second.”
… Unless someone finished the 100GbE IEE 802.3 / 100GBASE spec, the fastest commercial network cards are 10GbE, which, given the PCI-E bus bandwidth and memory controller limitation more-or-less limit you to 40GbE (2 x dual port Intel 10GbE NIC) per socket.
As for the achievement in question, I can’t say that I’m overly impressed (though the linked article may be missing some interesting details). A well balanced kernel router can easily receive ~4Gbps and send ~10Gbps -per- core, making fairly easy to route >40Gbps on dual socket machine, and >80Gbps on a quad socket machine.
Than again, the linked article is slim on valid (…) details, so I may have missed the main event…
