  1. IEEE 802.11 Introduction to IEEE P1905.1 Authors: Date: 2011-01-19 David Hunter, Panasonic

  2. Abstract This presentation contains an introduction to the new IEEE standards work group, IEEE P1905.1. David Hunter, Panasonic

  3. IEEE P1905.1 – the goals • P1905.1 work group home page • http://grouper.ieee.org/groups/1905/1/ • PAR: • http://grouper.ieee.org/groups/1905/1/P1905.1_PAR.pdf • Scope: • The standard defines an abstraction layer for multiple home networking technologies. The abstraction layer provides a common data and control Service Access Point to the heterogeneous home networking technologies described in the following specifications: IEEE P1901, IEEE 802.11, IEEE 802.3 and MoCA 1.1. • The standard is extendable to work with other home networking technologies. • The abstraction layer supports dynamic interface selection for transmission of packets arriving from any interface (upper protocol layers or underlying network technologies). End-to-end Quality of Service (QoS) is supported. • Also specified are procedures, protocols and guidelines to provide a simplified user experience to add devices to the network, to set up encryption keys, to extend the network coverage, and to provide network management features to address issues related to neighbor discovery, topology discovery, path selection, QoS negotiation, and network control and management. David Hunter, Panasonic

  4. P1905.1 Core Building an abstraction layer: sits on top of the MAC Provides single interface for upper layer access Replaces the multiple MAC service interfaces to upper layers, both: MAC-SAP for data MLME-SAP for management and control Provides new features across multiple networks End-to-end QoS across all networks Simplified user experience Single network management for all networks Early proposed requirement: single ‘secure’ association for all networks Minimal version would appear to be a sublayer Not a complete ISO layer (layer 1, layer 2, …) Provides service interface to upper layers (IP layer and higher) Provides protocol interface to the 802.3, 802.11, MoCA and 1901 MACs But whether P1905.1 sticks to the minimum is up to its voters Slide 4 David Hunter, Panasonic

  5. 1905.1 Design Options Interface to the upper layers might be: Brand new data and management (MAC-like) interface But: requires every one of today’s applications to be re-written Upper layer interface of one of today’s MACs: 802.3 OR 802.11 OR MoCA OR 1901 One wins, the others lose The customers of most chips get to rewrite their applications If 1905.1 is even moderately successful, it will affect the 802.11 market So: which interface should win? Maybe the one that dominates home networking today? That’s an easy guess in this meeting . Slide 5 David Hunter, Panasonic

  6. What should 802.11 members do? Participate in P1905.1: voting counts But: IEEE P1905.1 is an *entity-based* work group: Companies (not individuals) belong to the work group Entity-based = = IEEE corporate program One vote per company One-person consultancy has same vote as a $100B conglomerate Good news: the companies of most 802.11 members already belong to the IEEE corporate program One catch: Basic: only can vote on Sponsor Ballots Advanced: can participate in Work Groups Costs: according to size (revenues) of the company Slide 6 David Hunter, Panasonic

  7. IEEE P1905.1 Summary • New IEEE standards work group: first meeting was Dec 2010 • Goal: unified cross-technology interface to the upper layers • Participation: IEEE *entity* rules • IEEE-SA corporate program – one vote per company (or alliance) • Two levels of IEEE entity membership: Basic and Advanced • Basic: can vote on any entity-based sponsor ballot • Advanced: can participate in any entity-based work group • Advanced is considerably higher cost than Basic • IEEE corporate channel: http://standards.ieee.org/develop/corpchan/ • IEEE-SA P&P for entity work groups: http://standards.ieee.org/about/sasb/audcom/baseline_ent.doc • A product interface that might influence your market David Hunter, Panasonic
