3. Starting Point 02-676r0-RRM-SG & 02-652r1-RRM-SG
March 2003
Starting Point
02-676r0-RRM-SG & r1-RRM-SG
No explicit structural distinction between AP and STA: Current MIB architecture
“Type” or “class” information
What you measure directly between you and someone: under MAC branch
Include PHY parameters (RSSI, CCA) here?
What you are told by others: under SMT branch
Actions requested via SNMP: under SMT branch
How to connect this action back to MIB variables under other branches?
Conformance table untouched for now
Only additions at the end of structures for backward compatibility

4. Split between SMT and Others
March 2003
Split between SMT and Others
Under SMT Reports Table
Results of Action/Report
Action Request to Self
Action Request to Others
Under MAC per STA table and under PHY
Measured locally
Results of routine operation
Autonomous measurements for any reason
More info available than action/report, especially at AP

5. Variable Choices Obvious ones extended to per STA
March 2003
Variable Choices
Obvious ones extended to per STA
Per Inf counters: Not all May be needed
Place Holders for TGh Report elements
Need to work out How to encode in MIB
As is into Octet String?
each field into a varible is preferred for readibility
A lot of things will not be useful or otherwise better off without
Let’s find them and remove
A lot were missed in this attempt
Let’s find them and discuss
Caveat: More Variable Names need to be localized.

6. Issues Time information on non-counter variables
March 2003
Issues
Time information on non-counter variables
the instant measurement performed
Measurement duration, Averaging duration
Duration is usually handled in TU
Keep only the latest? Or last few? Window averaging?
MIB is not very good with history keeping
Assume current system time “TimeTicks” SNMP type and indicate time relative to it?
Relative to TSF?
Data Aging to keep table growing too much: How long?
And of course, the precise definitions of many parameters.
So, unfortunately, text for draft was not fully finished

7. Counter Table (per Interface)
March 2003
Counter Table (per Interface)
Standard Counters here

8. Per-STA stats Table Includes all STAs ever heard or communicated
March 2003
Per-STA stats Table
Includes all STAs ever heard or communicated
Some variables do not make sense to those not in communication or depending on mode, or STA or AP
Split them into?
In direct communication and Just heard (decoded headers for contention, CCA, CTS, Beacon)?
AP table and STA table?

9. Per STA stats Table Standard Counters March 2003

10. Reports Table Not my measurement or observation
March 2003
Reports Table
Not my measurement or observation
Placeholder for reports by other STAs on a third STA
Otherwise go into per-STA table
Will TGk implement “measure THIS on THAT STA”?
Since these variables need to be transferred between STAs, Many will have to be taken out
We have not figured out how to do transfer
Many of the standard counters
Many of the per-STA variables

11. Reports Table Standard Counters March 2003

12. Actions Table As per Mike Moreton’s 02-652r1
March 2003
Actions Table
As per Mike Moreton’s r1
Queue for actions set by SNMP
Results can go into per STA stats table if the link involves yourself or in direct communication
Results can go into report table if involves a third party
Results can be notified to SNMP manager if notification bit is set

16. Status Thanks to discussions and help from the group
March 2003
Status
Thanks to discussions and help from the group
Per STA stats under MAC looks good
Other parts need more work
Suggestion:
Instead of working informally, move to incorporate per STA stats table into Draft so that everyone can look at it more seriously.
Byoung-Jo “J” Kim, AT&T Labs-Research

17. March 2003
Motion
Move to Request the editor incorporate the marked MIB sections into the TGk draft
In r1
dot11staStatsTable under MAC branch
Local measurements
