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. ## Adjourn 15:30
