15 OBSS Directions How the information is used to share the medium?
May 2009 OBSS Directions How the information is used to share the medium? Set of information that needs to be exchanged Impact of the OBSS solution on ‘legacy’ BSSs Implementing the OBSS solution needs to provide a compelling benefit (in the presence of legacy BSSs) – otherwise no one will implement it See 7.5 in 08/944r7 Ganesh Venkatesan, Intel Corporation

16 September 2008 November 2007 doc.: IEEE /2752r1 doc.: IEEE /1003r0 802.1AVB Topics May 2009 What is the worst case delay when streaming under different conditions? (good conditions – 1msec, moderate – 8 msec and heavy congestion 800 msec) subset of options used channel conditions Is there a mechanism specified in to propagate the worst case delay under current conditions, to upper layers? What data makes the most sense? 2. are there mechanisms to pass this data? 3. if not, can we define them? TSPEC mapping to 802.1Qav TSPEC – plan for a presentation How are QoS errors fed back from the MAC? Need to determine if 11k traffic stream/category statistics are sufficient. Expectations (from .1AVB perspective) for the Joint meeting : Answers to #1 above Updates on #2 and #3 SRP over – need for relaying stream information (09/403r0) – list choices, pros/cons of each for discussion jointly Update each other on status of drafts Slide 16 Ganesh Venkatesan, Intel Corporation Page 16 Alex Ashley, NDS Ltd Peter Ecclesine, Cisco Systems

17 September 2008 November 2007 doc.: IEEE /2752r1 doc.: IEEE /1003r0 May 2009 Timeline Review D1.0 WG letter ballot – according to timeline, scheduled for Nov 2009 PAR topics: Graceful degradation of audio video streams when there is insufficient channel capacity, by enabling packet discarding without any requirement for deep packet inspection, Increased robustness in overlapping BSS environments, without the requirement for a centralised management entity, Intra-Access Category prioritization of transport streams by modifying EDCA timing and parameter selection without any requirement for deep packet inspection, Improved link reliability and low jitter characteristics for multicast/broadcast audio video streams Interworking with relevant 802.1AVB mechanisms (802.1Qat, 802.1Qav, 802.1AS) D1.0 is required to be complete – address the PAR scope entirely Potential for a 4 month slip Slide 17 Ganesh Venkatesan, Intel Corporation Page 17 Alex Ashley, NDS Ltd Peter Ecclesine, Cisco Systems
