The 10 gigabit/second Lambda Network is Live


The Lambda Network Project is a glimpse into the future when everything is tied over a network that zips bits at speeds of 10 gigabits per second. I wrote about this back when I worked at Red Herring. Like the first generation educational networks led to the formation of what we call Internet, this could be the next evolutionary step…

> The University of California, San Diego and NASA Goddard Space Flight Center have conducted the first successful system test of a new 10-Gigabit per second (Gbps) Ethernet optical path connecting the two institutions roughly 3,000 miles apart. The dedicated bandwidth is so broad that it allowed scientists to work with each other via high-definition video while also collaborating in real time on visualizing massive amounts of remote land and weather data. The bandwidth allowed scientists to study distant data objects and visualizations up to 1,000 times larger than is feasible using the World Wide Web.

Larry Smarr, director of the California Institute for Telecommunications and Information Technology (Calit2) and former chair of NASA’s Earth Systems Science Advisory Committee says, “It really is like the two research centers are just next door to each other!”

Internet2 has been up and running for a while. What were you waiting for?


victor. I think the big deal is that this is end-to-end 10GigE over a great distance. Most deployed 10GigE is limited to core-router to core-router connections (most of which are probably within a building). The screaming ethernet connections offered to end customers premises are 10Mpbs, 100Mbps, or 1Gbs. This is 10GigE premise to 10 GigE premise over a great distance. This must mean that the core is probably greater than 10GigE (probably OC-768/40Gig or some multi-lambda thing) Very cool.

I don’t quite get it. 10G has been available commercially for a while. It’s quite widely used in enterprises and service providers. So what’s the big deal ?
