review of par
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

802 11 qos for 802 1 avb meeting
802.11 QoS for 802.1 AVB meeting
  • Tutorial on 802.11 QoS
    • TSPECs and what they mean
    • Volunteers:
      • Graham Smith (DSP Group)
      • Osama Aboul-Magd (Nortel Networks)

criteria for evaluating multicast video proposals
Criteria for evaluatingMulticast 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

Agenda for next AVB meeting
  • Tutorial on 802.11 QoS
    • TSPECs and what they mean
    • We need a volunteer
  • Tutorial on 802.1Qat
    • Traffic classes, their delay/latency and throughput characteristics

plans for dallas meeting
Plans for Dallas Meeting

Joint meeting with 802.1AVB (2 meeting slots)

802.1Qat and 802.11 QoS

(a) a tutorial on 802.11e, specifically on TSPECs and what they mean; management interface to 802.11 QoS, (by 802.11)

(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 802.11 TSPECs (jointly).

Update on the status of 802.1Q C-tag CFI bit

Status of 802.11aa (what we have done so far)
