Researchers from the University of Arizona, the University of Southern California (USC), and seven other institutions say they are trying to save the Internet by making it cheaper, faster, and better.

In 2008 the researchers received a five-year, $18.5 million U.S. National Science Foundation grant to establish the Center for Integrated Access Networks (CIAN). CIAN's goal is to solve the data crisis by helping optoelectronic technology reach its full potential.

"CIAN is aimed at transforming the Internet to a high-speed network that uses less energy, is more reliable so that it reconfigures itself around network impairments, is scalable to make it suitable for a growing number of end users, and is not too costly," says CIAN director Nasser Peyghambarian.

The Center's researchers have made key breakthroughs in transforming the way large amounts of data are transmitted and they have developed three new techniques of restoring degraded optical signals. USC's Alan Willner says computer terminals eventually could be outfitted with chips that use these techniques to clean up damaged data.
