This report explores how networking research could overcome the evident obstacles to help achieve this vision for the future and otherwise better understand and improve the Internet. The report, which reflects interactions among networking researchers and outsiders (researchers from fields other than networking) at CSTB’s January 2001 workshop, as well as subsequent discussion by the Committee on Research Horizons in Networking, stresses looking beyond the current Internet and evolutionary modifications thereof and aims to stimulate fresh thinking within the networking research community. Since it is not a formal research agenda (which would, among other things, entail a much more intensive effort than is afforded by an exploratory workshop such as this), the report does not, for example, review past literature and current research programs but instead briefly characterizes past progress, current efforts, and promising directions. It focuses on three key areas in which networking research might be invigorated: measuring the Internet, modeling the Internet, and making disruptive prototypes.
