IETF 102 - ALTO Session
Minutes
Compiled by Jan Seedorf from Meetecho recording (key points, hums, decisions)

Chair Slides (Vijay):
Ñ Vijay: trying to close milestones / remaining WG items, then see what to do
with the WG, options after the current milestones are done are either
re-chartering or closing the WG, discussion should happen later today on this
issue, both current chairs (Vijay, Jan) will not be available as chairs for a
re-charter but will help with a transition if that will happen Ñ Vijay: good
progress with remaining milestones, performance-metrics draft has gone under
TSV-ART review to make progress, cost-calendar draft is out of the WG,
xdom-discovery draft is ready to move out of the WG (waiting for one more
revision, shepherd write-up ready), incr-update-sse is also post WGLC and just
few remaining issues Ñ Vijay: remaining milestone drafts except
performance-metrics will be discussed today: cdni-request-routing, path-vector,
unified-props Ñ Richard Yang: performance-metrics authors will address comments
from TSV_ART review and issue a  new version soon Ñ Vijay: no face-to-face
meeting in Bangkok, possibly a virtual meeting instead

Remaining Issues in ALTO (Richard Yang)
Ñ Richard presents on the Òbig pictureÓ regarding remaining issues in ALTO (see
slides for details), big picture open issues are studying how to smartly *use*
ALTO for network orchestration, and how to *integrate* infrastructure
measurements smoothly into ALTO server information ÑVijay: good taxonomy and
summary on the status of ALTO

ALTO Survey (Shawn Lin) & Next Steps for WG / General Discussion
Ñ Shawn presents on ALTO Survey (see slides for details)
Ñ Mirja: question is to see if there is enough energy to finish more work on
ALTO in a timely matter, also need to see if people from the industry come with
key use cases and have an actual need for ALTO extensions for concrete
problems, also need to consider if making ALTO very generic may also have
drawbacks, as a complex ALTO framework may incur heavy implementations Ñ Lyle
Bertz: have had ALTO system in production in the past, need to re-engage people
from the industry to come to ALTO Ñ Mirja: Do people from the industry have a
real need for ALTO solutions? Ñ Lyle: Answer is yes, but need to tie ALTO into
overall orchestration for operators to be useful Ñ Bšrje: have interest in
multi-domain orchestration with ALTO and the unicorn work Ñ Richard: plan to
organise a workshop to elaborate on use cases with industry Ñ Sabine: mobile
networks are very complex and heterogenic with respect to end user devices,
there is a need for ALTO here to convey endpoint diversity information (e.g.
for multiparty communication) Ñ Mirja: need to align with other WGs, this may
also raise interest in ALTO ÑVijay: interest from vendors and operators in
ALTO, problem is the backlog with work items, so need to finish the outstanding
milestones asap (hopefully within the next two IETF meetings) and then discuss
on re-chartering
