2. doc.: IEEE 802.11-09/1259r0 Submission Nov 2009 Michael Bahr, Siemens AGSlide 2 Abstract Asking the Task Group about a direction for resolving miscellaneous RFI comments.

3. doc.: IEEE 802.11-09/1259r0 Submission Nov 2009 Michael Bahr, Siemens AGSlide 3 Content PANN & RANN in Beacon Implementation Confusion with CIDs 953 & 954 Periodicity in PANN / RANN

4. doc.: IEEE 802.11-09/1259r0 Submission Nov 2009 Michael Bahr, Siemens AGSlide 4 PANN & RANN in Beacon Why they should be removed beacon bloat (15+19 = 34 byte) security: not protected implementation cannot count on them method: periodic PANN & RANN management frames inside mesh BSS Why they should be there beacons are sent anyway method: periodic PANN & RANN elements in beacons

5. doc.: IEEE 802.11-09/1259r0 Submission Nov 2009 Michael Bahr, Siemens AGSlide 5 Strawpoll Should the RANN & PANN be removed from the beacon? CIDs 442, 846 accept Yes: No: Dont know/Dont care:

6. doc.: IEEE 802.11-09/1259r0 Submission Nov 2009 Michael Bahr, Siemens AGSlide 6 Implementation Confusion with CIDs 953 & 954 Draft D3.04: still there as dot11MeshHWMPActivated renaming happened with D3.02 Locations: Table 7-8 Beacon frame body Dot11MeshStationConfigEntry

7. doc.: IEEE 802.11-09/1259r0 Submission Nov 2009 Michael Bahr, Siemens AGSlide 7 Solution (A) Delete dot11MeshHWMPActivated (Accepted resolution to CIDs 953 & 954) Table 7-8 Beacon frame body no entry in Dot11MeshStationConfigEntry

8. doc.: IEEE 802.11-09/1259r0 Submission Nov 2009 Michael Bahr, Siemens AGSlide 8 Solution (B) Replace with MIB variable that holds the path selection protocol identifier of the active path selection protocol Table 7-8 Beacon frame body Dot11MeshStationConfigEntry

9. doc.: IEEE 802.11-09/1259r0 Submission Nov 2009 Michael Bahr, Siemens AGSlide 9 Solution (C) Remove RANN from Beacon (would also solve CIDs 442 & 846) Table 7-8 Beacon frame body no entry in Dot11MeshStationConfigEntry

10. doc.: IEEE 802.11-09/1259r0 Submission Nov 2009 Michael Bahr, Siemens AGSlide 10 Strawpoll Which solution do you prefer? Solution (A): delete dot11MeshHWMPActivated Solution (B): replace with MIB variable dot11MeshActivePathSelectionProtocol A: B: D(ont care):

11. doc.: IEEE 802.11-09/1259r0 Submission Nov 2009 Michael Bahr, Siemens AGSlide 11 Periodicity in PANN / RANN CIDs 156, 157, and 645 want to add the interval to the Portal Announcement (PANN) element and the Root Announcement (RANN) element respectively Proposed resolution: –reject Reasons: –Both PANN and RANN are purely informative elements that only annouce the presence of a portal or a root mesh STA –They dont setup any forwarding information that would need to be maintained –Mesh stations in power save mode wont miss PANNs and RANNs (stored at transmitting mesh STA until receiver becomes available)

12. doc.: IEEE 802.11-09/1259r0 Submission Nov 2009 Michael Bahr, Siemens AGSlide 12 Motion: Periodicity in PANN / RANN Moved, to resolve CIDs 156, 157, and 645 with resolution Reject and with resolution notes: The inclusion of a periodicity field in the PANN and RANN information elements is not considered necessary, because –Both PANN and RANN are purely informative elements that only annouce the presence of a portal or a root mesh STA –They dont setup any forwarding information that would need to be maintained –Mesh stations in power save mode wont miss PANNs and RANNs (stored at transmitting mesh STA until receiver becomes available) Mover: Seconder: Yes: No: Abstain
