Work Completed• 802 Overview and Architecture Draft 1.2 letter ballot

– Discussed status of comment resolutions– Two items of interest to 802.11:

• Bit error rate and Packet error rate• OUI-36 per 802.11p usage

– Will likely need 802.11 WG consolidated comments for next letter ballot in next couple of months – probably will schedule a teleconference once dates are known.

• P1905.1– Intent is to ‘glue’ together technologies for in-home networks– Make request to EC to request a formal liaison with P1905,

explicitly to include document sharing.• Minutes are in 11-11/1537

802.1AVB “Packet preemption”/ultra-low latency

• Presentations to 802.3– http://www.ieee802.org/1/files/public/docs2011/new-avb-boiger-joint-AVB-802-3-1

111.pdf– http://www.ieee802.org/1/files/public/docs2011/new-avb-nfinn-real-time-networks-

1111-v04.pdf– General theme is “customer requirement” for ultra-low latency (< 3 to 20 us – on

wired networks(?)) and/or highly predictable traffic– Requirements from Automotive and Industrial Control uses– Looked at Qav queue shapers and time-gated queues, insufficient to meet

requirements• 802.1AVB also discussed this topic with 802.11aa this week

– Did not bring clear requirements for wireless networks– 802.11 should monitor, be aware of this general push, and prepare to start

considering an 802.11 response• No action for 802.11 at this time – awareness only

Registration Authority Committee (RAC)

• ISO/IEC versions of 802.11 Standards– 802.11 (and other WGs) is working with JTC1/SC6 to get the ISO/IEC versions of

802.11 Standards up-to-date (or withdrawn, as appropriate)– RAC expressed concern to be careful about maintaining a correct chain of control

over the Registration Authority of OUIs (and thereby MAC address allocations), as documents are updated (and thereby, those documents’ references to the RAC)

• Vendor error resulting in use of incorrect OUI– Will likely lead to policy changes at RAC, and modified legal agreements attached

to OUI allocations– A side-effect is consideration of a policy to support allocating a specific, requested

OUI, for an additional fee. (Everyone get ready to request your “designer license plate”!)

• RAC is undergoing major discussions and changes to move to larger OUI/EUIs, up to EUI-64 (64 bits)– Due to large number of physical devices expected over next few years, plus usage

of OUI-based address space for virtualized devices– Demand for addresses estimated to have quantities in the 1010 range, soon
