IETF 101 London MBONED Agenda Tues, Mar 20, 2018 9:30AM-12PM 1E Park Suite (Held jointly with PIM WG) Note taker: Brian Adamson/Justin Dean Etherpad notes: https://etherpad.tools.ietf.org/p/notes-ietf-101-mboned Jabber Log: https://www.ietf.org/jabber/logs/mboned/2018-03-20.html Audio log: https://ietf.org/audio/ietf101/ietf101-parksuite-20180320-0930.mp3 Video log: https://www.youtube.com/watch?v=-APQy9ZiTBo MBONED notes: Note Well Agenda and agenda bashing no comments Status of Active WG Docs: mboned-mtrace-v2-21 updated draft due to DISCUSS security issues raised mboned-ieee802-mcast-problems-01 adoped since last wg and merged two drafts into one mboned-multicast-info-model-02 updated ready for adoption? mboned-multicast-models-02 wasn't ready for adoption previously was trimed down and may be ready soon Deprecating ASM for interdomain Multicast Tim Chown (Presenter) mboned-deprecate-interdomain-asm-00 Presented the high-level statement - does anyone have any issues with it? If so please come to the microphone. (Slide6) Stig: did you depreprecate RP completely or still use it within a domain? Tim/Lenny: We are just saying don't use it for interdomain What is the state of interdomain multicast? How much is actually in use? Lenny: We will be able to answer that better in the next presentation Stig: You might want to call this out if its about random people or domains that are closely related ?: I think we should call out that it's between differently run domains not domains run by a single entity Tim: Who has read the new draft? 2 hands raised Lenny: Of the people who have read it or have been paying attention who would support adoption? ~8 hands raised Lenny: against? 0 hands. We will take it to the list but seems a go. Lenny: anyone have any comments on the 3 other Rob Evans: do we need the asm to ssm maping? It seems like a lot of work for very limited use. Jake Holland: There is legacy hardware that supports IGMPv2 but won't work without the mapping. Michael: technical disscussion about MLDV2, s,joins ?: It will take a while to get rid of ASM applications if we ever do so it might be okay to do the mapping method Tim: mapping meant to be an interim method; such things do have a habit of persisting though Jake: Are there examples BCP about converting applications that we have to work off of? Tim: Not that I'm aware of. Jake: That might be something I can help with. Public AMT Relay Deployment on the MBONE Experience William Zhang (Presenter) Jake Holland: Further work slide. The problem with Web Assembly is that there is no UDP support so you are going to have a problem with that. If you want to persue this there was a hackathon project as a wrapper for UDP. Should consider this approach Lucas Pardue: I was also working with Jake on the hackathon. We were working on getting quic working in the web browser. Threading is also an issue. There are also issues on how you'd impliment this as a web app. We ended up using web sockets. Rob Evans: As well as sweeping active sources did you look at sap or sdp? Lenny: No we only really looked at active sources not sap/sdp announcements. There is traffic on the SAP group so someone is using it but we didn't look at that. Rob Evans: Meteorological data comes in EUMETSAT which I find interesting to find on the I2 network Lenny: Another interesting thing about EUMETSAT is that they were one of the few to use SSM. Lenny: The original goal of AMT is to have end users access multicast content but the gateway capabilities seem to be more focused on networking devices (not hosts). Any assistance from people would be helpful. Updating VLC with AMT GW might be nice Jake: One more suggestion of AMT resources there is a cisco vm that has AMT support that can be downloaded. Do we know if these groups are joinable by asm or ssm? Multicast Yang Model Sandy Zhang (Presenter) WG adoption? Lenny: Who has read the updated draft? 2 hands Lenny: Other folks in the room we did get comments back from the yang doctors seemed like supporting it. Who in the room would support addoption? ~5 hands raised. Jake Holland: Thank you for the update it was one of the more readable YANG documents that I've read. Multicast in the Data Center Mike McBride (Presenter) It would be good to get an update. I'd love to work with someone to udate the draft it's already a wg draft so it would be an easy way to get your name on a draft for any interested/capable persons. Multicast vs WiFi Charlie Perkins (Presenter) Jake Holland: section 4.5 of the draft I would like to see filled out. In the draft I would love to see how that works. Michael: I've seen devices where you turn on ip snooping and it turns off all other ethernet multicast. Lenny: There is an IGMP snooping draft and I'm pretty sure it doesn't say turn off multicast. Michael: But is there a draft that says don't do that. This isn't just a wireless issue as some wired devices do this. Should we only focus on 802 or include things like this in the wired world. Perkins: I think this draft should focus on wireless. Alvero: Joel asked what should the IETF do. IT would be really nice if part of the output from the WG produces this answer. Because I saw the section on the presentation which asked that question but I would find it useful to have some output from the WG to answer that question. Perkins: There were some comments from Joel on the list but those comments haven't been incorportated into the draft. There will be a new revision of the draft within 2 weeks.
