One writer described the grid as a "parallel Internet." Ruth Pordes, executive director of the Open Science Grid, which oversees the U.S. infrastructure for the LHC network, describes it as an "evolution of the Internet." New fiber-optic cables with special protocols will be used to move data from CERN to 11 Tier-1 sites around the globe, which in turn use standard Internet technologies to transfer the data to more than 150 Tier-2 centers. 20,000 Linux servers power the grid. "It's using some advanced features and new technologies within the Internet to distribute the data," Pordes says. "It's advancing the technologies, it's advancing the [data transfer] rates, and it's advancing the usability and reliability of the infrastructure.""
