associated press new York although it has already taken nearly four de Cades to get this far in building the internet some University re searchers with the Federal govern ments Blessing want to scrap All that and Start Over the idea May seem unthinkable even absurd but Many believe a clean slate approach is the Only Way to truly address Security mobility and other challenges that have cropped up since Urcla pro Fessor Leonard Kleinrock helped supervise the first Exchange of meaningless test data Between two machines on sept 21969 the internet works Well in Many situations but was designed for completely different assumptions said dip Ankar Ray Chaudhuri a Rutgers University professor overseeing three clean slate projects if s sort of a Miracle that it continues to work Well today no longer constrained by slow connections and computer processors and High costs for storage re searchers say the time has come to rethink the internet s underly ing architecture a move that could mean replacing networking equipment and rewriting software on computers to better Channel future traffic Over the existing pipes even Vinton Cerf one of the internets founding fathers As code the internet transitioning to a next generation internet could be Akin to changing the engines on a moving air plane routers and other networking devices will Likely need replacing person Al computers could be in store for software upgrades headaches could arise Given the fact that it wont be possible to simply shut Down the entire network for maintenance with companies groups and individuals depending on it every Day and just think of the costs potentially billions of dollars advocates of a clean slate internet a restructuring of the underlying architecture to better handle Security mobility and other emerging needs agree that any transition will be difficult but researchers Arent deterred the premise of the clean slate design is Lef s Start by saying How should it be done Independent of can we retrofit it said Andrea Gold Smith an electrical engineering professor at Stanford once we know what the right thing to do is then we can say is there an evolution Al path one transition scenario is to run a parallel network for applications that truly need the improved functions people would Migrate to the new sys tem Over time the Way some Are now abandoning the traditional Tele phone system for Interne based phones even As the two networks run Side by Side some believe the current internet will never go away and the fruits of the research could go into than exist ing architecture you cant overhaul an International network very easily and expect everyone to jump on it said Leonard Kleinrock a Urcla professor who was one of the driving forces in creating the original internet the

concept engineers tacked on improve ments to support mobility and improved Security but researchers say All that adds complexity reduces performance and in the Case of Security amounts at most to bandages in a High stakes game of cat and mouse workarounds for Mobile devices can work quite Well if a Small fraction of the traffic is of that Type but could overwhelm com Puter processors and create Secu Rity holes when 90 percent or More of the traffic is Mobile said Nick Mckeown co director of Stanford clean slate program even if the original designers had the Benefit of Hindsight they might not have been Able to incorporate these features from the get go we made decisions based on a very different technical land scape said Bruce Davie a Fel Low with network equipment maker Cisco
