IPPM group, Please find below the draft minutes of last week's meeting. They are a merger of notes submitted by Erik and Matt (thanks, gentlemen), all errors are probably mine :-) (I'm pretty bad at making minutes). Comments welcome, Henk - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - IPPM-WG @ IETF 76 ================= Chair: Henk Uijterwaal Scribes: Erik Burger Matt Zekauskas (remote participant) 1. Administrativia. The Chair opened the meeting with the usual stuff. The co-chair could not make the meeting and sent his apologies. Erik Burger voluntered as scribe. The agenda was approved without changes, the speakers for items 4 through 8 will all present through WebEx. 2. Status of drafts and milestones The chair gave an overview of drafts not discussed today: * draft-ietf-ippm-more-twamp-03.txt: published as RFC5618 * draft-ietf-ippm-multimetrics-13.txt: RFC5644 * draft-ietf-ippm-reporting-04.txt: this draft passed WGLC, it is now on the chair's desk and will be passed to the IESG shortly. * draft-ietf-ippm-framework-compagg-08.txt: Ready for WGLC right after this meeting. 3. Reporting drafts. (Al Morton) a. draft-ietf-ippm-reporting-04.txt: see previous item. b. draft-ietf-ippm-reporting-metrics-00 This draft became a WG item, comments received on the individual submission version have been included in the -00 version. The author is looking for more readers. 4. Metrics composition drafts status. (Al Morton) * draft-ietf-ippm-framework-compagg * draft-ietf-ippm-spatial-composition Looking for WGLC on framework draft, Henk says this will be done soon. Spatial composition updated based on what agreed to. Resolved a comment on an early session. Resolved a case to compute e2e performance for multiple segments of a path even if e2e routing is not working. This case is now mentioned. Ruediger Geib said he had some comments that he will post to the list. 5. TWAMP features a. draft-ietf-ippm-twamp-reflect-octets-03 (Morton, Ciavattone) Al briefly outlined the proposed changes that the draft makes to the protocol. It is essentially ready to go to WGLC but the readership has been small. As this makes significant changes to the protocol, a review would be good. Unfortunately, the folks active in the initial version have all moved to other things. The chairs will discuss this further. b. draft-ietf-ippm-twamp-session-cntrl-02 (Morton, Chiba) This draft is ready to go to WGLC. 6. Advancing Metrics along the standards path (Geib, 20') http://www.ietf.org/id/draft-geib-ippm-metrictest-01.txt Ruediger presented this draft. Comments from the floor: Matt Mathis: How aggregated was path measurement taken from? It is on the backbone of a major provider, thus heavily aggregated. MM said we need a statistician to understand what happens when temporal resolution taken to low values. Focus was on delay, just a little on packet loss and jitter. Al: ideally think about test plans for validation while developing the metrics on throughput. Is there interest in the work group for this draft? Al, Reza, Rudi, Gerard have been working on the draft. At the SF meeting, 4 others expressed interest but they haven't commented. Henk will chase them. Ruediger is interested in doing live testing, but then sees issue with shipping equipment around the world. There are some possibilities though, to be investigated. 7. TCP Throughput Testing (Barry Constantine, 20') http://www.ietf.org/id/draft-constantine-ippm-tcp-throughput-tm-00.txt This is potential new work, presented to see if there is interest. Barry gave an overview of the draft. Comments: Reudiger: It is OK to standardize methods and metrics, but probably not pass/fail metrics. He does not like idea of putting monitoring system on that constantly loads network. Barry: Intention is for this to be internal, turn-up testing. Not targeted for constant monitoring. Take to list for interest as a WG item. 8. Burst Loss Metrics/Dick Duffield (20') http://tools.ietf.org/html/draft-duffield-ippm-burst-loss-metrics-01.txt This draft was presented by Nick. Comments. Matt Mathis: Has not read draft; however, it sounds like the assumption is the narrowest link is the link likely to be lossy. That may not be true. Nick will do another draft. Submit to WG for consideration. 9. AOB No other business came up. -- ------------------------------------------------------------------------------ Henk Uijterwaal Email: henk.uijterwaal(at)ripe.net RIPE Network Coordination Centre http://www.xs4all.nl/~henku P.O.Box 10096 Singel 258 Phone: +31.20.5354414 1001 EB Amsterdam 1016 AB Amsterdam Fax: +31.20.5354445 The Netherlands The Netherlands Mobile: +31.6.55861746 ------------------------------------------------------------------------------ Nobody ever went broke underestimating the taste of the American public.
