Matt Zekauskas2 June 2006 Small group traded … and a concall Dan Magorian Joe Metzger Jeff Boote Eric Boyd Matt Zekauskas Result was a “v0.0” requirements document that needs iteration Possibly as a WG under NTAC auspices

Matt Zekauskas3 Obligatory Pointer Observatory v0.0a.pdf

Matt Zekauskas4 Don’t Break Anything Keep existing Observatory capabilities

Matt Zekauskas5 Potential (New) Focus Areas Technology Issues Is it working? How well? How debug problems? Economy Issues – interdomain circuits How are they used? Are they used effectively? Monitor violation of any rules (e.g. for short-term circuits) Compare with “vanilla” IP services?

Matt Zekauskas6 Big Goals? Extend research datasets to new equipment Circuit “weathermap”; optical proxy Auditing Circuits Who requested (at suitable granularity) What for? (ex: bulk data, streaming media, experiment control) Why? (add’l bw, required characteristics, application isolation, security)

Matt Zekauskas7 Consumer Statistics What might a consumer want to know? Availability stats (per ckt, per segment, periodically, available seconds, unavailable seconds (planned, unplanned (equip? human?) Error stats (pre/post FEC, if triggers maint) Usage (creation, hold times, errors)

Matt Zekauskas8 Diagnostics Auditing (ckt creation, teardown, errors, utilization if possible) Ability to trace to find dysfunctional link (link setup packets, passive tap) Ability to identify and track rate policing (or rate limiting, or rate mismatches)

Matt Zekauskas9 Quality Control Circuit Statistics (setup times, call blocking times/rates, teardown time, in-service bit or packet error rates, in-service circuit failure rates) Packet statistics for standard IP/Ethernet links (rates, loss, latency, jitter, utilization) Periodic active tests (setup-test-teardown; tests ctl plane, ports (vary), attenuate to look for boundary conditions)

Matt Zekauskas10 Economy: Currency How is it handed out? Is it traded? If so, trade stats Are credits stored? If so, how much “Burn rate”

Matt Zekauskas11 Economy: Health (growing? Shrinking? Trends?) Supply measurement Demand measurement Demand characterization (more granular than connector) Which university or research group? Purpose? (research/app/testing/offload other link) Economy rules violations?
