16 September 2008 Review of PAR 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 No current activity 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) Alex Ashley, NDS Ltd

18 Criteria for evaluating Multicast Video proposals
September 2008 Criteria for evaluating Multicast Video proposals Flexibility (high reliability and efficiency vs high scalability - 100s in MC group) Shall work with 5 STAs Should work with 10s of STAs Comparable to a single stream unicast with limited retries: PLR delay and delay jitter Bandwidth efficiency (since video throughput can be high) Support for Multiple transmissions per beacon period Compatible with legacy STAs Provide support for duplicate detection Allow for rate adaptation Preserve power save performance Not require h/w change Provide support for collision avoidance Document 08/1093r0 Alex Ashley, NDS Ltd

Moved: Liwen Chu Second: Craig Warren Vote: Yes 3, No 0, Abstain 1 Motion passes Slide 20 Alex Ashley, NDS Ltd Page 20 Alex Ashley, NDS Ltd Peter Ecclesine, Cisco Systems

21 Agenda for next AVB meeting
September 2008 Agenda for next AVB meeting Tutorial on QoS TSPECs and what they mean We need a volunteer Tutorial on 802.1Qat Traffic classes, their delay/latency and throughput characteristics Mapping between AVB and .11 TSPECs Status of 802.1q C-Tag CFI bit Alex Ashley, NDS Ltd

22 Plans for Dallas Meeting
September 2008 September 2008 Plans for Dallas Meeting Joint meeting with 802.1AVB (2 meeting slots) 802.1Qat and QoS (a) a tutorial on e, specifically on TSPECs and what they mean; management interface to QoS, (by ) (b) a tutorial on 802.1Qat, specifically the traffic classes and what their delay/latency and throughput characteristics are (by 802.1AVB) and (c) define a map between each 802.1Qat traffic class to TSPECs (jointly). Update on the status of 802.1Q C-tag CFI bit Status of aa (what we have done so far) Listen to technical proposals Discuss process Requirements documents for other PAR topics Slide 22 Alex Ashley, NDS Ltd Alex Ashley, NDS Ltd
