| --- This message came from the IEEE 802.11 Working Group Reflector ---
Thanks, Robert, I’ll note that integration of L4S with 802.11 (“Wi-Fi”) has been a stagnant topic within the ARC SC for man months, as we awaited this updated information from WBA. All, My takeaway from the paper is that this integration is complicated, when affects of medium access are included (in particular, in a setting that is not trivially lightly loaded). I see there is extensive discussion in the paper about modifications (or at least clarifications?) of the EDCA mechanisms in 802.11, to help alleviate the medium access delays. I’m not sure if such discussion about EDCA fundamentals are best in ARC, or TGbn (which the paper says is already considering the topic? – I know L4S has been discussed in TGbn, but I don’t recall anything about changing how medium access works? Maybe the low-latency techniques of TGbe are more relevant?). Anyway, I have the L4S topic (in general – and it can be focused on the medium access question) on the ARC agenda for next week. If anyone is interested in this aspect of the L4S discussion, please let me know. I note that ARC is in conflict with TGbn for all the ARC meetings next week (of course), so if a change of agenda plan is desired, let me know that, also, and I can work on that. Mark From: Stacey, Robert <robert.stacey@xxxxxxxxx> --- This message came from the IEEE 802.11 Working Group Reflector --- Hello Members, Today I received a liaison from the WBA, which I have put on the document share: https://mentor.ieee.org/802.11/dcn/24/11-24-1569-00-0000-liaison-from-wba-guidelines-for-l4s.docx I have made the document referenced in the liaison available in the members area: https://www.ieee802.org/11/private/liaisons/index.html The relevant text from the liaison is reproduced below: ---- Dear IEEE 802.11 Working Group Chair, The WBA Members formed a technical activity in early 2024 called E2E Wi-Fi QoS & L4S, focused on investigating the benefits of enabling Low Latency, Low Loss, Scalable Throughput (L4S) over Wi-Fi via simulations and proof-of-concept implementations, showing the benefit of L4S to significantly reduce buffer delays, identifying potential areas for further work (including standardization), and providing implementation guidelines. The group has recently finished an implementation guidelines document that provides an overview of L4S Technology, L4S support in Wi-Fi, Implementation choices, Simulation and Proof-ofConcept implementation test results with EDCA medium access and Conclusions. The group leadership would like to formally liaise with IEEE 802.11 the final draft that will be published later to the WBA Members in Q4 2024 – find the copy attached to this message. The program intends to follow up with extending the study to optimize transmission delays due to media access. This will include strategies to select appropriate EDCA parameters and other mechanisms defined in IEEE802.11ax, IEEE802.11be and being discussed for consideration in IEEE802.11bn. Specific requests: • WBA invites IEEE 802.11 WG members to provide opportune feedback on the document, as well as any other areas that WBA should in future phases of this work. • WBA E2E QoS & L4S members would like to present an overview of this effort to IEEE 802.11 WG in a future IEEE 802.11 session (Nov 2024 Plenary). Yours sincerely, The WBA E2E Wi-Fi QoS & L4S Chairs ---- Regards, Robert Stacey To unsubscribe from the STDS-802-11 list, click the following link: https://listserv.ieee.org/cgi-bin/wa?SUBED1=STDS-802-11&A=1 To unsubscribe from the STDS-802-11 list, click the following link: https://listserv.ieee.org/cgi-bin/wa?SUBED1=STDS-802-11&A=1 |
