Researcher Only High Bandwidth Network 209

Posted by samzenpus from the elite-fiber dept.
Icarus1919 writes "A brand-new 10 gigabit per second per user optical fiber network is now available to researchers in the U.S. (compared to Internet2, which offers only 10 gigabits of bandwidth total, regardless of the number of users). The National Lambda Rail, as it is known, is named for the 40 different wavelengths of light it uses to send data within the fiber network. In the past, researchers have complained about the relatively (relative when you're dealing with terabytes of data) small bandwidth they can access to send data, and the addition of the NLR will most likely be a boon to research."

    From what I understand, they will be using quite a bit of the bandwidth in this as well. Do we know how much data must be trasfered at once? Is this continuous data, or is it in chunks? How much ram would it take to hold all of this data until it can be placed unto a disk for storage?

        It is not really 10 Gbps per user. New Scientist got that wrong. It's a fiber-optic infrastructure capable with 40 lambdas max. A lambda is a wavelength of light. They use DWDM [wikipedia.org] to split the light on the fiber into 40 lambdas. One lamdda = 10 Gbps.

        Now, a single user can, for a period of time, get a whole lambda for himself for a particular application. That's a big deal for researchers. But don't think that everyone at an NLR connected institution automatically has a 10 Gbps link to everyone else on NLR. Most of the users, at best, probably have 1 Gbps ethernet to their desktop. This isn't for browsing the web and playing Doom. It's to connect huge data stores in San Diego to supercomputers in Pittsburgh.
