How distributed is the existing Internet, and what are the implications of growing consolidation/mergers for ISPs?
How well are addresses aggregated and what effect is aggregation having on Net performance?
How stable is Internet routing, and how is this changing over time? How asymmetric is routing; is this relevant to performance?
How can visualizations of routing tables be most useful to backbone engineers?
How do operators/engineers visualize traffic going through their network infrastructure clouds?
Is 'real-time' visualization important?
How do network engineers use such information (or not) to determine/tune IGP metrics within their clouds?
How significant is the need for tools to assess how BGP topology changes (either intended or routing instablity) affect reachability and connectivity quality?
For a real-time cross-ISP routing debugging tool to be useful, what information would it need to provide?
What is the extent and effect (on user-perceived performance) of asymmetric routes?
What tools are available for tuning IGP metrics?
How much of IPv4space is allocated/announced/routed/used by traffic/(recently) returned to IANA? What are the trends and their implication for implementation of IPv6, …IPv8?
What kinds of 'engineering' information might the FCC and other regulators require relating to routing and peering? What 'policy insights' can be gained from analysis of the routing tables?
