•Need to build infrastructure to support troubleshooting:
–Requires repetitive and on-demand measurements with appropriate
security
model.
–Provide recommended/accepted set of tools for delay, RTT, loss,
route tracking, "bandwidth" estimation.
•Include archiving and access to data, analysis and reporting of
repetitive data.
–Allow for evaluation, validation and comparison of new
measurement tools, TCP stacks, applications (e.g. file transfer).
–Reverse traceroute, looking glass, remote tcpdump (e.g. SCNM),
remote testing of connection (ANL NDT),
–Traceroute archives
–Make tools easier to comprehend and use by scientists
–Encourage efforts such as Internet2 E2Epi efforts to provide measurements inside the
cloud
•Extend to ESnet & other NRNs, and beyond
•Fund collaboration across boundaries
–Ubiquitous coverage (require multiple toolkits): Inter agency, international, hi-speed,
digital divide, long term and current
