FW: [ippm] Fwd: New Liaison Statement, "Performance Measurement Liaison Response to Broadband Forum"

BMWG,

A few weeks ago, a proposal for a liaison reply to several prior BBF
liaisons was prepared by David Sinicrope, the IETF/Broadband Forum
Liaison Manager <[email protected]>, combined with text
prepared by Brian Trammell for IPPM, and circulated on our list.

The final reply text has been agreed and transmitted, see below.
Thanks to all involved, especially David for initiating this in Berlin.

regards,
Al
bmwg co-chair

> and the LMAP WG formed (to consider the architectural framework and
> operational components), both groups look forward to communicating with

> > We note that you would like to reference IETF protocols and work to

> division of work and scope and would be happy to cooperate along these
> lines.  We encourage specific communication with each of the individual
> working groups via their Chairs along the lines of their charters.  For
> topics that cross one or more WGs, please address the liaison to the
> Chairs of all of the relevant working groups and the liaison manager from
> the IETF who will help direct the liaison to the appropriate WG or IETF

> > The LMAP WG is reviewing your March 2013 Liaison and notes the following
> requests for information:
> > Feedback on the use of SIP to provide an inter and intra domain
> mechanism to probe test target resource availability.
> > Comments on the use of DNS-SD(RFC6763) and mDNS (RFC6762) to support
> BBF's service attribute communication.
> > Information model development for test and report parameters
> >
> > LMAP WG Response:
> >
> > The LMAP WG was formed in June and held its first meeting in July of
> this year. Following the goals and milestones as outlined in the WG
> Charter that can be found in the above link, the WG will be focussed on
> finalizing Use Case and Framework documents and then beginning work on the
> Information Model document. The Information Model was mentioned as an area
> of interest by the BBF in the March Liaison. The LMAP WG would welcome
> input from the BBF as it begins work on the Information Model document.
> For reference, the Informational Model scope as described in the LMAP WG
> Charter is included for reference:
> > Information Model, the abstract definition of the information carried
> from the Controller to the MA and the information carried from the MA to
> the Collector. It includes
> >   * The metric(s) that can be measured and values for its parameters
> such as the Peer MA participating in the measurement and the desired
> environmental conditions (for example, only conduct the measurement when
> there is no user traffic observed)
> >   * The schedule: when the measurement should be run and how the results
> should be reported (when and to which Collector)
> >   * The report: the metric(s) measured and when, the actual result, and
> supporting metadata such as location. Result reports may be organized in
> batches or may be reported immediately, such as for an on-demand
> measurement.
> > In regards to interest of using DNS-SD and mDNS in support of service
> attribute communication between devices within the home network, the LMAP
> WG would defer this question and possible further analysis to work that is
> taking place in the Homenet WG. It should be noted that currently the mDNS
> Protocol is constrained to a single link based on its use of link-local
> multicast. If the BBF would be interested in the use of mDNS and DNS-SD in
> a multi-segmented home network, this would require new work to those
> protocols that is being discussed as part of a new Working Group.
> Discussion of that WG charter language is currently taking place.
> >
> > In regards to the use of SIP as a inter-domain and/or intra-domain
> mechanism for the discovery of test target (Measurement Peer in LMAP
> terminology) availability, this point represents communication that would
> take place between a Measurement Agent and a Measurement Peer.
> Communication requirements as part of a test between a MA and its
> measurement target (Measurement Peer) is currently not included as one of
> the work items per the LMAP charter but may be a topic of discussion for
> future work.
> >
> > IPPM WG Response:
> >
> > Please be advised that the IPPM WG has considered updates to RFC 2680
> and 2681 in their March 2013 rechartering, but these have been deferred
> until it is clear what impact the effort to update the framework (2330)
> and the effort to define a registry on the March 2013 charter will have on
> these updates. IPPM expects that the result will be compatible with 2680
> and 2681, and as such developments based on these RFCs may continue as
> they are.
> >
> > Many of the issues with 3148 raised in Question 1 of the December 2012
> BBF liaison may be addressed by draft-ietf-ippm-model-based-metrics-00, on
> which work is progressing under their current charter; discussion of
> issues with bulk capacity measurement not addressed therein is welcome on
> the [email protected] mailing list.
> >
> > With respect to the remaining outstanding questions, the IPPM WG will
> take them as information that BBF is considering the use of 3393 and 6349
> as well; IPPM is not considering updates to these at this time, so they
> remain a stable basis for further work, noting again in the latter case
> that draft-ietf-ippm-model-based-metrics-00 aims to address issues in
> using TCP to measure TCP bulk transfer capacity.
> >
> > IPPM understands from Question 6 that 'moving up the stack', looking
> specifically at VoIP, streaming video, and DNS resolution time, are of
> interest to BBF. IPPM is not currently working on metrics in this area,
> but would certainly consider contributions thereon under its current
> charter, and have reviewed at least one individual draft on buffered
> streaming video performance during the chartering discussions in March
> 2013.
> >
> > As for the general line of these questions (especially 6), please note
> the ongoing registry effort on the IPPM charter. There are three
> individual drafts: draft-bagnulo-ippm-new-registry, draft-bagnulo-ippm-
> new-registry-independent, and draft-claise-ippm-perf-metric-registry. The
> authors are currently working on a unified approach to a performance
> metrics registry, with the intention that the outcome be adopted for
> further development within the IPPM WG. This registry will be populated
> with recommended metrics for LMAP use cases, which would represent a
> consensus statement from IPPM on the metrics IPPM consider useful in this
> area. Work in this area is ongoing, and we welcome commentary on the
> [email protected] list once the unified registry document is published.
> >
> > We noted that there might be interest in the identification of test
> reference points.  This is currently on the IPPM WG charter and we now
> have an initial working group document
> (http://datatracker.ietf.org/doc/draft-ietf-ippm-lmap-path).

> > The IETF encourages those in the BBF who are interested in this IETF
> work, to participate and help drive the work via the relevant IETF WG
> email lists noted above and the IETF development processes.  While formal
> liaison communication is necessary and beneficial, direct, active
> participation by interested parties is very helpful and complementary to
> drive the deliverables needed between the organizations.  Please note that
> access to all relevant IETF working groups, email lists, documents and
> process is open so than any interested party may participate and
> contribute.

> > Likewise, the IETF would be happy to provide input and feedback on BBF
> related work.  We understand the BBF is a membership organization and may
> restrict access to its relevant works in progress.  To facilitate
> cooperation with the IETF, please liaise any work in progress you would
> like the IETF to consider, review, comment on, collaborate on, etc., with
> the understanding that access to the liaison and its attachments will be
> open and not be restricted or limited to BBF membership.
