TGt/WNM Collaboration TGt Performance to be WNM managed January 2003 IEEE 802.11-03/100r1 doc: IEEE 802.11-04/1441r0 November 2004 TGt/WNM Collaboration TGt Performance to be WNM managed Joe Kwak, InterDigital Victoria Poncini, Microsoft Submission Kwak( InterDigital), Poncini (Microsoft)

Kwak( InterDigital), Poncini (Microsoft) January 2003 IEEE 802.11-03/100r1 Outline TGT Purpose, output WNM Purpose, output Common concerns Useful TGT metrics---> new WNM managed parameters Conclusions Kwak( InterDigital), Poncini (Microsoft) Submission

Kwak( InterDigital), Poncini (Microsoft) TGT Purpose To enable testing, comparison, and deployment planning of 802.11 WLAN devices based on a common and accepted set of performance metrics, measurement methodologies and test conditions This includes identification of useful performance metrics Output captured in Recommended Practice Many identified metrics may not be defined in 802.11 standard Kwak( InterDigital), Poncini (Microsoft) Submission

Kwak( InterDigital), Poncini (Microsoft) WNM Purpose To effect a complete and coherent upper layer interface for managing 802.11 devices in wireless networks Device management means restricted to items within a STA (or AP). Management to include configuration management, resource management, access and security management, and performance management. In each case the "management” implies the need for monitoring and control of STA parameters. Certain TGt metrics may be candidates for standardization as new management parameters in STAs. Kwak( InterDigital), Poncini (Microsoft) Submission

Kwak( InterDigital), Poncini (Microsoft) TGt metrics for WNM TGt will identify relevant metrics, sub-metrics and parameters useful for performance testing and performance prediction. Any metric or sub-metric should be included in WNM amendment IF: It is not already defined in the standard AND IF It affects STA or network performance OR IF It is a test configuration control parameter which should be standardized in all STAs to permit uniform testing. WNM will implement measurement or reporting of metrics for management. WNM will provide monitoring and control of parameters for management. Kwak( InterDigital), Poncini (Microsoft) Submission

Parking Lot for Metrics and Sub-metrics Propose that as metrics are identified and classified, a WNM “flag” be used to indicate which metrics should be added to the standard. Performance metrics by OSI model layers Data Link Application Transport Physical Layer Mxyz Mxyz ** Mxyz ** Mxyz Mxyz Mxyz ** Mxyz ** = WNM flag Kwak( InterDigital), Poncini (Microsoft) Submission

Kwak( InterDigital), Poncini (Microsoft) TGt - WNM Coordination TGt’s schedule leads WNM’s significantly, so timeline supports TGt output--->WNM. Propose that relationship be informal TGt attendees may input contributions to WNM WNM attendees may base contributions on TGt work Attendees of both groups would be ideal volunteers for this effort Attendees from InterDigital, Microsoft and other companies will promote this work. Kwak( InterDigital), Poncini (Microsoft) Submission

Kwak( InterDigital), Poncini (Microsoft) Conclusions TGt work will identify metrics and parameters useful for performance testing, prediction and for management. TGt’s Recommended Practice output document cannot standardize any new metric or parameter within 802.11 STAs. WNM is tasked with amending the 802.11 standard for management purposes. It is expected that certain metrics identified for testing and prediction in TGt should be standardized for management in WNM. Kwak( InterDigital), Poncini (Microsoft) Submission
