  2. Abstract This presentation gives an overview of text document 11-09/0857r0 which gives changes to normative text in order to resolve some comments related to the proxy update information element. Changes relate to: • abbreviation of Proxy Update • PU  PXU • extension of format of Proxy Update element • structure is per proxy information • arbitrary structure of proxy information (individual add/delete, lifetime, proxy mesh STA address) • proxied device • external device, represented device Michael Bahr, Siemens AG

  3. PU • comment CID 1090 • requests to use other abbreviation • ambiguous abbreviation • Proxy Update • Peer U-APSD • used in „PU buffer STA“, „PU sleep STA“ • comes from IEEE 802.11z D4.0 • wrong spelling: correct is Pooh! • proposal: PU  PXU (PUC  PXUC) Michael Bahr, Siemens AG

  4. Format of PU • proxy information on mesh STA • represented MAC address • proxy mesh STA MAC address • this mesh STA • other mesh STA (= destination mesh STA, if this mesh STA is the source mesh STA) • proxy information lifetime • limited flexibility with current PU • either add or delete for all proxy information • no flexibility on proxy information lifetime • mesh STA can only report proxy information where it is proxy mesh STA Michael Bahr, Siemens AG

  5. Format of PXU • Add / Delete this proxy information • Source Proxy indicates whether Proxy MAC Address subfield is present. If not present, Proxy MAC Address = PXU Originator MAC Address • Proxy Information Lifetime subfield is present or not Michael Bahr, Siemens AG

  6. Proxied Device • Proxied MAC Address confusing with Proxy MAC Address • suggestions for proxying proxied • external • might be to broad in situations relating to proxy information: not every external device is necessarily a proxied device • represented • proposal • use represented device/address etc. when talking about proxy information and closely related issues • use the more appropriate of external or represented in other cases • other suggestions? Michael Bahr, Siemens AG

  7. Motion Move to adopt document 11-09/0857r0 as resolution to comments with CIDs 879, 914, 1090, all with counter. Michael Bahr, Siemens AG

  8. References • IEEE 802.11s WLAN Mesh Networking draft standard, D3.02 • 11-09/0857r0 „Proxy Update Element Revision“(proposed text changes) Michael Bahr, Siemens AG
