Easy things First In the order of difficulty of Standardizing Month 2000 doc.: IEEE 802.11-00/xxx November 2002 Easy things First In the order of difficulty of Standardizing Passively Observed Parameters during normal operation CCA, RSSI, Noise Power, Frame Counts, States, MAC addresses, Beacons, etc. Trending them? Transfer of Parameters between STA to AP: 11h-like.. SNMP to STA over Radio is not desired nor workable Need Request/Response over Air Can be used for Actively Measured Parameters Actively Measured Parameters May need a way to Quiet the medium Control AP Requesting Change of Config/Behavior of its STAs External Entity communication via SNMP or modified IAPP?

Step-by-Step Standardization? Month 2000 doc.: IEEE 802.11-00/xxx November 2002 Step-by-Step Standardization? First, Define and Add “Passively Observable” Parameters to 802.11 MIB Standard Impact Minimal Non-AP STAs may start recording upon request from AP This Presentation is limited to this While the above is being balloted Transfer of Parameters between STA to AP Actively Measured Parameters: extend TGh? May Need some architectural thinking Work on Control Issues: Maybe a next TG Definitely Need some architectural thinking Byoung-Jo "J" Kim, AT&T Labs-Research John Doe, His Company

Distinguish AP and non-AP STA in MIB? November 2002 Distinguish AP and non-AP STA in MIB? Some parameters make sense only for APs Some parameters make sense only for non-AP STAs SNMP to STAs not desirable nor feasible Current MIB does not have anything specific for AP but all APs are STAs RRM should distinguish them “Explicitly”? Any implications to other part of 802.11? RRM should distinguish them “Implicitly”? Potentially Confusing, but fits the current 802.11 MIB Architecture mostly (11f added some AP specifics) “This Presentation takes this approach” Byoung-Jo "J" Kim, AT&T Labs-Research

Passively Observed Parameters into 802.11 MIB Month 2000 doc.: IEEE 802.11-00/xxx November 2002 Passively Observed Parameters into 802.11 MIB Current 802.11 MIB has the following sub-branches dot11smt, dot11mac, dot11res, dot11phy, dot11Conformance Current 802.11 MIB has some Per-Interface Stats: dot11CountersTable) under dot11mac: Extend/Replace with dot11macStatsTable for per Interface stats beyond the current MAC counters? Extend doc11phy/dot11phyDSSSTable and dot11phyOFDMTable for PHY stats? New Per-STA table is needed: dot11STAStatsTable under dot11mac & dot11phy? One Private MIB had this under “Forwarding Table”, containing corresponding MAC addresses : Reasonable place but out of 802.11 scope? Another Private MIB has this under “Association Table”, which excludes STA observed but not associated, or other APs Need to include all known STAs, APs, regardless of association Byoung-Jo "J" Kim, AT&T Labs-Research John Doe, His Company

Important Suggestion! During this Presentation November 2002 Important Suggestion! During this Presentation Let’s NOT Focus on Particular Variables I’m not proposing any particular variables, just place holders Let’s Focus on Overall Structure Byoung-Jo "J" Kim, AT&T Labs-Research

How to move info between STA to AP? Month 2000 doc.: IEEE 802.11-00/xxx November 2002 How to move info between STA to AP? Proprietary Methods Observed in Current Products for a few parameters Simple IP level proprietary protocol Proprietary extension of Management Frames Need Info from hardware implementers Naturally leads to Active Measurements 11h does this for some parameters Reported parameters from other STAs should go under dot11smt, indexed via integer containing reporters’ address and observed addresss Byoung-Jo "J" Kim, AT&T Labs-Research John Doe, His Company
