## Slot#    Start   Duration  Information
## #1       14:30   5 min   Title:  Intro, WG Status, Draft Status
Presenter:      Chairs

Toerless Eckert: can we doodle for the interim time?
Chairs: Please discuss on the list

## #2       14:35   10 min  Title:  OAM Framework
Presenter:      Greg Mirsky
Draft:  https://datatracker.ietf.org/doc/html/draft-ietf-detnet-oam-framework-03

Janos Farkas: The two other OAM drafts, MPLS and IP, maybe hold them from
publication until get to LC for OAM Framework, to make sure there are no last
minute changes. Greg Mirsky: Agree.

## #3       14:45   5 min   Title:  OAM for The Service Sub-Layer
Presenter:      Balázs Varga
Draft: 
https://datatracker.ietf.org/doc/html/draft-varga-detnet-service-sub-layer-oam-00

No Comments.
Yali Wang: (via chat) this is an interesting work. One question that where does
the OAM specific "PINGSeqNum" be carried in Ping packets? Balázs: (via chat)
there are two drafts detnet-ip-oam and detnet-mpls-oam have defined the SeqNum
but maybe need further discussion. But you can see it.

## #4       14:50   5 min   Title:  PREOF for DetNet IP
Presenter:      Balázs Varga
Draft:  https://datatracker.ietf.org/doc/html/draft-varga-detnet-ip-preof-00

Pascal Thubert: How would aggregation work? What if in middle of network want
to aggregate, do we end up with UDP inside UDP in which case flow info is lost?
Balazs: No, terminated at DetNet Relay Nodes. Will provide more info via the
list.

David Black: Should this be a standards track doc?
Balazs Varga: This work was developed using existing build blocks, we put them
together, attempting to do this draft as Informational, but for interop
considerations, maybe should be standards track. Lou Berger: I would like to
see more discussion on the list on various alternative options, e.g. using IP
over MPLS over UDP/IP, which only adds maybe 4 bytes. Need to discuss more
options like this on the list.

## #5       14:55   5 min   Title:  IPv6 Hop-by-Hop Options for DetNet
Presenter:      Pascal Thubert
Draft:  https://datatracker.ietf.org/doc/html/draft-pthubert-detnet-ipv6-hbh-04

Lou Berger: No time left for questions; I have some questions but we will need
to discuss on list, e.g., is this more RAW focused? Pascal Thubert: Not
intended to be RAW specific. Can discuss on list.

## #6       15:00   5 min   Title:  Packet Ordering Function
Presenter:      Balázs Varga
Draft:  https://datatracker.ietf.org/doc/html/draft-varga-detnet-pof-01

Toerless Eckert: Why is there no externally observable behavior e.g. switching
between A and B stream but already have delayed A stream. Would be nice to make
these externally observable.

Lou Berger: If there is interest in working on this POF topic, please indicate
via the chat. Greg Mirsky: (via chat) Yes, interested in PREOF work.

## #7       15:05   5 min   Title:  RSVP for TSN Networks
Presenter:      Dirk Trossen
Draft:  https://datatracker.ietf.org/doc/html/draft-trossen-detnet-rsvp-tsn-00

Lou Berger: (via chat) @AD will need to discuss where this goes if it
progresses - in addition to DetNet, candidates include TEAS and CCAMP.

John Scudder: Ack.

Lou Berger: Not a lot of interest in RFC 2205 based sol'ns so far, need to
discuss.

## #8       15:10   5 min   Title:  BGP Flow Specification for DetNet Flow
Mapping Presenter:      Quan Xiong Draft: 
https://datatracker.ietf.org/doc/html/draft-xiong-idr-detnet-flow-mapping-00

Lou Berger: This needs more discussion on the list, e.g. to see if there is
support for the use case. Maybe take to IDR WG?

## #9       15:15   5 min   Title:  Services Deployment Guideline in DetNet
Network Presenter:      Joanna Dang Draft: 
https://datatracker.ietf.org/doc/html/draft-dang-detnet-deployment-00

Lou Berger: Appreciate contributions from service providers, please continue
this topic on list.

## #10      15:20   5 min   Title:  Bounded Latency Problems
Presenter:      Toerless Eckert
Draft: 
https://datatracker.ietf.org/doc/html/draft-eckert-detnet-bounded-latency-problems-00

Lou Berger: There is an Interim planned on this broader topic. Please remove
history and subjective info at beginning of this draft, it is not relevant to
discussion - please stick to technical information. Toerless Eckert: Please put
specific items on the list. Lou Berger: (via chat) My recommendation is drop
section 2. Section 1 and 3 also need significant review from the WG.

## #11      15:25   5 min   Title:  Micro-burst Decreasing in Layer3 Network
for Low-Latency Traffic Presenter:      Zongpeng Du Draft: 
https://datatracker.ietf.org/doc/html/draft-du-detnet-layer3-low-latency-03

Lou Berger: Thanks for bringing this work, it is of interest to the working
group.

Lou Berger: We were asked to keep session to 1 hour, next time we should take 2
hours - it would be a lot more useful if we had time for discussion. If have
follow up questions, please take to the list. Also comments on planned times
e.g. for interims, please bring to list. We appreciate your contributions.
