"The internet could be made more secure, reliable and powerful by overlaying new networking technology on top of the existing backbone, according to the world's leading microchip maker, Intel. The company's chief technology officer, Pat Gelsinger, warned that the internet needs a radical overhaul to address growing demand for access, bandwidth and more advanced internet programs. The message came in a keynote speech delivered at the Intel Developer's Forum in San Francisco, US, on September 9, 2004. Gelsinger recommended building a new network layer on top of the existing internet infrastructure. This would mimic the way the internet's fundamental protocols were built on top of phone line infrastructure 30 years ago. 'As the network grows, applications are becoming more, not less demanding,' Gelsinger said. 'We need to replicate the thinking of 1973 and create an overlying network.'

The company's chief technology officer, Pat Gelsinger, warned that the internet needs a radical overhaul to address growing demand for access, bandwidth and more advanced internet programs. The message came in a keynote speech delivered at the Intel Developer's Forum in San Francisco, US, on Thursday. Gelsinger recommended building a new network layer on top of the existing internet infrastructure. This would mimic the way the internet's fundamental protocols were built on top of phone line infrastructure 30 years ago. "As the network grows, applications are becoming more, not less demanding," Gelsinger said. "We need to replicate the thinking of 1973 and create an overlying network." In-built intelligence Such a network overlay, constructed from new software and hardware, would have greater intelligence than today's internet routers and protocols, he predicted. "These new smart services could allow the internet to detect and warn of worm attacks, dynamically re-route network traffic to avoid delays and improve video webcasting," Gelsinger said. Not everyone is convinced this is the best solution, however. Jon Crowcroft, a networking expert at Cambridge University in the UK, thinks it would be better to rebuild the internet's foundations than add another layer of complexity. Crowcroft says network overlays only provide an effective way to test different reconfigurations. "Overlays are not a solution," he told New Scientist. "They are a way of testing solutions - not a substitute for really fixing the internet architecture." One of the main problems with an overlay network is security, Crowcroft warns, as compromising one part of the overlay could undermine the security of the entire network. Traffic jams In June 2003, Intel and Hewlett Packard helped found an experimental global overlay network called PlanetLab. This network consists of thousands of computers based at 60 different universities and research institutions around the globe. PlanetLab machines connect via the internet but use software to overlay a virtual network on top. This lets researchers implement novel networking protocols on a large scale without having to actually build such networks. The projects currently being tested on PlanetLab include networks that can automatically avoid internet traffic jams and throttle computer worms as soon as they start to spread.
