Ultrahigh-speed Internet2 gets 10x boost

NEW YORK (AP): The ultrahigh-speed Internet2 network just got 10 times faster, 
partly in anticipation of rising demand for capacity after the world's largest
particle collider opens near Geneva next year.

Until recently, the Internet2 had a theoretical limit of 10 gigabits per 
second, which is thousands of times faster than standard home broadband 
connections.
By sending data using 10 different colors, or wavelengths, of light over a 
single cable, operators are boosting the network's capacity to 100 Gbps.

That means a high-quality version of the movie ``The Matrix'' could be sent in 
a few seconds rather than half a minute over the old Internet2 and several
hours over a typical home broadband line.

The new Internet2 network was largely completed in late August, and its 
operators this week made it possible for researchers to temporarily grab an 
entire
10 Gbps chunk for specific applications, so that they do not slow down normal 
Internet operations.

``It's now possible for a single computer to have a 10 gigabit connection and 
we needed to have a way of making sure that those kinds of demanding 
applications
could be served at the same time as all the normal uses,'' Doug Van Houweling, 
Internet2's chief executive, said Wednesday.

The Internet2 network, run by Level 3 Communications Inc., parallels the 
regular Internet to let universities, corporations and researchers share large
amounts of information in real time.

An institution typically has one 10 Gbps connection to the 100 Gbps Internet2 
backbone for normal Internet usage, along with a second 10 Gbps connection
it can tap on demand for specific needs, Van Houweling said.

Physicists will likely be among the first to use that on-demand capability, Van 
Houweling said, when the $1.8 billion (euro1.27 billion) Large Hadron Collider
at the European Organization for Nuclear Research begins operations, now 
scheduled for May.

``There will be thousands of physicists who will all need to access the data 
coming out of the LHC,'' he said.

Astronomers, meanwhile, might one day use the faster network to link distant 
radio telescopes to get a clearer picture of the sky in real time, Van Houweling
said.

Internet2 already is planning future expansion. By adding certain equipment, 
Van Houweling said, the network can easily boost capacity another fourfold
