Network Science and Engineering (NetSE) Research Agenda: v1.0

1. Network Science and Engineering (NetSE) Research Agenda: v1.0 5th GENI Engineering Conference Seattle, WA 21 July 2009 Ellen Zegura, Georgia Tech

2. Context • Pre-2008 – Many significant, relevant activities • January 2008 – New NSF CISE AD Jeannette Wing charged a NetSE Coordinating Group • “To develop a compelling research agenda for the science and engineering of our evolving, complex networks.” • Summer and Fall 2008 • Workshops to elaborate on intellectual space • Complement pre-2008 activity • Today – Version 1.0 of Research Agenda

3. Foundations Breadth Core Workshops • Science of Network Design (Doyle, Wroclawski) • Theory of Networked Computing (Feigenbaum) • Behavior, Computation and Networks in Human-Subject Experimentation (Camerer, Kearns) • Network Design and Societal Values (Clark, Nissenbaum) • Network Design and Network Engineering (Rexford, Zegura) And, 2005 NSF Workshop on Overcoming Barriers to Disruptive Innovation in Networking (Anderson, Peterson, Shenker, Turner)

4. Contributors • GENI Planning Group • GENI Science Council • NetSE Council • Workshop chairs • Workshop participants • GPO staff • NSF staff • CRA/CCC • All told, ~150 researchers across many areas

5. Report Outline • Executive Summary and Recommendations • written to funding agencies • Synthesis Chapter • Motivation and Framing • One-pagers on Key Research Areas: • Challenges in Network Experimentation • New Mathematical Tools and Frameworks • New Disciplinary Innovations • New Interdisciplinary Conversations • Security Exemplar • Summary • Appendices: Five Workshop Reports

6. Recommendations 1 and 2 • Investment: US funding agencies must increase investment in research that will lead to a better Internet or risk a marginal future role. • Experimental capabilities: Funding agencies should rebuild the experimental capabilities of networking researchers, through funding individual systems-building efforts, providing adequate and persistent shared experimental infrastructure, and supporting research that leads to continued improvements in experimental methodology. (Takes (much) more than traditional NSF funding.)

7. Recommendations 3 and 4 • Foundations: Funding agencies should foster and support research activities relevant to network design within the theoretical computer science community, the new Network Science community, and other theoretical disciplines. • Breadth: Funding agencies should support a broad array of interdisciplinary research activities related to understanding the current Internet and designing future networks to include the Internet.

8. Example Research Directions • Developing discipline and methodologies to validate models, measurements and data and to evaluate candidate technologies in experimental environments. • Developing the foundations of a theory ofnetworkarchitecture that allows rigorous analysis and systematic design of complex networked systems, including organizational abstractions such as interfaces and layering. • Creating a new class of design methodologies and principles that is concerned with steering collective, emergent behavior over time, rather than producing a final artifact. • Understanding how the value placed on security differs among users, institutions and national governments and the implications for network design.
