Meet your next 'Net? Academics rethink the Internet's guts
Judging by the National Science Foundation's latest grants for Internet development, our universities are packed with scientists who think that the Internet is woefully unprepared for the future, and are anxious to tackle the problem. In fact, these people can't wait to untether cyberspace from its current rules and architectures.
- NSF has given Professor Lixia Zhang of the University of California at Los Angeles $1.5 million to evaluate "middlebox" -- a reference to features that sort of popped up around the original IP framework, like firewalls and web proxies -- for its scalability, security, and privacy via testbeds, simulations, and theoretical models.
- Rutgers University Professor of Electrical Engineering Dipankar Raychaudhuri has a somewhat parallel NSF project underway. He and his colleagues are working on a "clean-slate future Internet architecture" called "Mobility First." The framework will serve the 'Net as it moves further beyond the old PC/host client/server model and towards a mobile environment.
- Professor Jonathan Smith of the University of Pennsylvania defines his long-term ambition as "the creation of useful distributed computing systems." Smith and his NSF project colleagues are huge fans of cloud computing, but see security risks as a big damper on its development and expansion. And so they propose NEBULA -- "a potential future Internet architecture providing trustworthy networking for the emerging cloud computing model of always-available network services."
