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 of network architecture 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.
