A Component-Based
Network-Centric Operating System
for the Next Millennium

is an open source, distributed adaptable operating system being built by the Systems Software Research Group and by the Multimedia Operating Systems and Networking Group in the University of Illinois at Urbana-Champaign. Strong collaboration with other research groups is encouraged. We are currently working together with the Systems and Communications Group from the Universidad Carlos III, Madrid, and researchers at the University of São Paulo and University of Campinas.

Motivation:

Our research seeks to modify resource management in operating systems to accommodate frequent change. By identifying key technologies and approaches to support frequent update, by emphasizing user- and application-orientation, and by focusing on application and resource aware, network-centric architectures, this project shifts the emphasis of operating system design from more traditional resource management to the management of dynamically changing distributed resources within rapidly changing user environments.
