  1. ARC Closing Report Authors: Date: 2011-11-11 Mark Hamilton, Polycom, Inc.

  2. Abstract This document is the closing report for ARC SC, November 2011, Atlanta meeting Mark Hamilton, Polycom, Inc.

  3. 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 Mark Hamilton, Polycom, Inc.

  4. Teleconferences • No specific plan, will schedule with 10 days notice • Topic(s): • Next letter ballot on 802 Overview and Architecture • P1905.1 liaison comments Mark Hamilton, Polycom, Inc.

  5. January 2012 Goals • One 802.11 meeting slot planned to discuss 802 O&A comments Mark Hamilton, Polycom, Inc.

  6. 802.1AVB “Packet preemption”/ultra-low latency • Presentations to 802.3 • http://www.ieee802.org/1/files/public/docs2011/new-avb-boiger-joint-AVB-802-3-1111.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 Mark Hamilton, Polycom, Inc.

  7. 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• 802.11 (and other WGs) is working with JTC1/SC6 to get the ISO/IEC versions of 802.11 Standards up-to-date (or withdrawn, as appropriate) • RAC expressed concern to be careful about maintaining a correct chain of control over the Registration Authority of OUIs (and thereby MAC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 Mark Hamilton, Polycom, Inc.
