Network Access in a Diversified Internet

There is a growing interest in virtualized network infrastructures as a means to enable experimental evaluation of new network architectures on a realistic scale. The National Science Foundation's GENI initiative seeks to develop a national experimental facility that would include virtualized network platforms that can support many concurrent experimental networks, with the goal of reducing barriers to new network architectures. This paper focuses on how to extend the concept of virtualized networking through LAN-based access networks to the end systems. We demonstrate that our approach can improve performance by an order of magnitude over other approaches and can enable virtual networks that provide end-to-end quality of service.
