Observatory Requirements Strawman Matt Zekauskas, matt@internet2.edu Measurement SIG Fall 2006 Member Meeting Monday, 4-Dec-2006
June 2006 • Small group traded email… 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
Obligatory Pointer • http://measurement.internet2.edu/docs/ Observatory-2006-06-05-v0.0a.pdf
Don’t Break Anything • Keep existing Observatory capabilities
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?
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)
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)
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)
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)
Economy: Currency • How is it handed out? • Is it traded? If so, trade stats • Are credits stored? If so, how much • “Burn rate”
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?
