  1. 802.11aa – Robust Audio Video Transport Streaming San FranciscoClosing Report Date: 2009-07-17 Authors: Ganesh Venkatesan, Intel Corporation

  2. Abstract TGaa Closing Report for the IEEE 802.11 San Francisco Session (July 2009) Slide 2 Ganesh Venkatesan, Intel Corporation

  3. Goals for the session • Discuss [, adopt] proposals corresponding to graceful degradation and intra-AC [, intra-stream] prioritization • OBSS • Converge on the TGaa solution to OBSS • Discuss TGaa goals for OBSS with TGac • Joint meeting with 802.1AVB: • TSpec mapping • Triggered 802.11k traffic stream/category statistics • Other requirements on 802.11 that may be useful to AVB • Resolve comments from Internal review of Draft D0.01 • Review timeline Ganesh Venkatesan, Intel Corporation

  4. Technical Presentations Stream Classification Service (09/725r0) Implementation for Intra-AC Differentiated Services (09/0022r1) Applicability of .11s MCCA to HCCA OBSS (09/660r3) OBSS Sharing with Access Fraction (09/662r2) 40MHz Channel Selection (09/740r0) HCCAOP Scheme – Efficiency and Sharing 09/666r3) Proposal for OBSS (09/757r0) Agenda for the joint meeting with 802.1AVB (09/787r0) 20MHz versus 40MHz for Video (09/805r0) OSQAP OBSS Requirements Compliancy (09/882r0) Neighborhood Capture and OBSS (09/844r0) Slide 4 Ganesh Venkatesan, Intel Corporation

  5. Accomplishments • Listened to 11 technical presentations • Adopted the Drop Precedence submission into TGaa draft (726r1) • Listened to the complete OBSS solution (757r1) and started evaluating the proposal against the requirements document. • Met jointly with 802.1AVB (see next slide) • Decided not to meet in the September Interim • Teleconference schedule • Timeline review and noted a 4 month slip Ganesh Venkatesan, Intel Corporation

  6. Topics at the Joint meeting with 802.1AVB What is the worst case delay when streaming under different conditions over a 802.11 link? Is there a mechanism specified in 802.11 to propagate the worst case delay under current conditions, to upper layers? 802.11 TSPEC mapping to 802.1Qav TSPEC How are QoS errors fed back from the 802.11 MAC? SRP over 802.11 – need for relaying stream information (09/403r0) – list choices, pros/cons of each for discussion jointly Status Update on 802.11aa Status Update on 802.11v Goals for the November 2009 joint meeting Slide 6 Ganesh Venkatesan, Intel Corporation

  7. 802.11 Interim – September 2009 TGaa will not be meeting in Waikoloa Ganesh Venkatesan, Intel Corporation

  8. 802.1Qat Sponsor Ballot Pool • 802.1Qat will be forming a sponsor ballot pool soon • Encourage all SA members interested in 802.1Qat (and how it should work with 802.11) to join the pool Ganesh Venkatesan, Intel Corporation

  9. Goals for the November Plenary Complete internal review, compile comments and resolve them Start November Plenary with Draft 0.02 Complete tasks that came out of the joint meeting with AVB Listen to technical proposals Make progress toward addressing all PAR scope items Meet jointly with 802.1AVB Ganesh Venkatesan, Intel Corporation

  10. Teleconferences Mondays 11:00-12:30 Hrs ET on the following days: July 27, Aug 10, Aug 24, Sep 07, Oct 19, Nov 02 and Nov 30. Ganesh Venkatesan, Intel Corporation
