Without significant new investment, the Internet's current network architecture will reach the limits of its capacity by 2010, warned AT&T's Jim Cicconi at the Westminster eForum on Web 2.0 in London. "The surge in online content is at the center of the most dramatic changes affecting the Internet today," Cicconi says. "In three years' time, 20 typical households will generate more traffic than the entire Internet today." Cicconi says at least $55 billion in investments are needed in new infrastructure over the next three years in the United States alone, and $130 billion worldwide. The "unprecedented new wave of broadband traffic" will increase fifty-fold by 2015, Cicconi predicts, adding that AT&T will invest $19 billion to maintain its network and upgrade the core of its network. Cicconi adds that more demand for high-definition video will put an increasing strain on the Internet's infrastructure, noting that eight hours of video is loaded onto YouTube every minute, and that HD video consumes seven to 10 times more bandwidth than normal video. "Video will be 80 percent of all traffic by 2010, up from 30 percent today," he says.
