The Internet faces many challenges, including security, management and control. The research project explores a future Internet/networking architecture based on a well-proven hierarchical architecture that is untested at global levels. The architecture includes a flexible addressing scheme and a compact four layer protocol stack. The radical change to the Internet architecture would be potentially transformative from a socioeconomic and business perspective. The scientific problems to be addressed are hence multidisciplinary. The technical and socioeconomic feasibility for the new network architecture, as well as the likely patterns of adoption for such a radical change are investigated. Intellectual merit: This research asks how a fully hierarchical architecture, with adequate redundancy at different levels in this design, results in a robust structure that is also scalable. The solution distributes the "switching decisions," the management of how traffic moves from one point to another, to all levels of a hierarchy of communications providers: it allows the traffic to be managed independently wherever the traffic is flowing. The replaces present highly interdependent routing and network management architecture. The research will show how this architecture is robust and stable with a potential for future growth. A key contribution of the architecture is a scalable and flexible hierarchical addressing scheme, where key network functions are relegated to different levels in the hierarchy, and this also provides better management and control. The research includes proof-of-concept by interfacing diverse wireless networks in the architecture.Broader impact: A new network architecture resulting from the SWITCHNET research could create radical changes in the economics of communications networks and ultimately have a very large impact on the economy and society. The conceptual architecture is almost ideally scalable. It is very much simpler to manage than the present architecture. As an example of the broad impact of SWITCHNET manageability, by enabling fundamentally better provider control, the architecture would open the door to new methods of identifying and pushing back denial of service, an economically and nationally much needed capability. Furthermore, this research could provide the breakthrough architecture for attaining the all-optical goal and thus address that national challenge to create a more energy-efficient network. Approaches to achieving such a purely optical communications infrastructure have long been sought.
