CEDAR KNOLLS, N.J. – If you're a bit skeptical that the World Wide Web is truly global, a new report from Probe Group might change your mind. According to the telecom think firm, North American originating and terminating routes accounted for less than half of overall international peak IP (Internet protocol) traffic in the past year, for the second year in a row. Probe analyst Tony Marson expects global Internet traffic to double every year until it reaches a peak in 2007. Fueling that growth will be improving economic conditions beginning next year, increased broadband penetration and growth of 2.5G and 3G mobile access and the disappearance of financially fragile operators from the marketplace. The United States will continue to have the largest domestic backbone during this period, Marson says, but peak U.S. demand will no longer be more than twice that of the next-largest domestic Internet backbone, China.
