1. path and round trip time measurements

• 1.1 project focus
• 1.2 why not one-way trip time measurements?
• 1.3 measurement methodology
• 1.4 initial observations (hop distance distribution)
• 1.5 initial observations (frequency of IP addresses in paths)
• 1.6 observations: visible outdegree (indicates many next hops/peerings)
• 1.7 scope of CAIDA measurements (12 mo projection)
• 1.8 architecture
• 1.9 visualization efforts
• 1.10 data visualization: RTT candle plots
• 1.11 Cisco with prefix cache
• 1.12 Cisco running CEF
• 1.13 data viz: RTT candle plots, to aggregate larger data sets
• 1.14 further RTT visualizations
• 1.15 macroscopic topology visualization
• 1.16 next steps
