A Proposed Usage Model Methodology for High Throughput Task Group

This proposal outlines a methodology for creating realistic and straightforward usage models, allowing for accurate evaluation and comparison. It includes goals, use cases, application types, and model specifications to guide the development process.

  1. A Proposed Usage Model Methodology for High Throughput Task Group Adrian Stephens (adrian.p.stephens@intel.com) Eldad Perahia (eperahia@cisco.com) Sean Coffey (coffey@ti.com) Adrian Stephens, Intel et al

  2. Methodology Goals • To allow measurement of properties of a proposal so that it can be evaluated against our criteria • To be adequately realistic • To be as simple as this permits • To get a common set of assumptions • To allow apples-apples comparison Adrian Stephens, Intel et al

  3. Goals of this submission • To get agreement to the methodology • Agreement to the principle, not the details • Straw Poll • Highlight that lots of TBDs need to be researched • We can work on the methodology in this meeting • But need to go away and look for figures • Call for interest in setting up a special committee to fill in the TBDs Adrian Stephens, Intel et al

  4. Use Cases / Scenarios • Enterprise • Planned “cellular” deployment • Hot spot • Large numbers of clients • Uncoordinated deployment of APs from different vendors and by different service providers • Home • Mix of multimedia and data • Mixed • Mix of co-channel legacy and HT devices • + others TBD (e.g. backhaul) Adrian Stephens, Intel et al

  5. Web Browsing Email File server Instant Messaging Interactive Video (e.g. netmeeting) + others we haven’t thought of yet Video Gaming HDTV High Quality Audio VoIP phones File sharing Backup Applications Adrian Stephens, Intel et al

  6. Application Types • TCP vs UDP, “Down” vs “Up” • TCP application follows a repeating: wait, transmit request, wait for response cycle. • UDP application follows a wait, transmit cycle • Each application has specified distributions for: • Wait duration • Request length (“up” applications) • Response length (“down” applications) Adrian Stephens, Intel et al

  7. Application Specification (example) … + the other applications Adrian Stephens, Intel et al

  8. Usage model specification • For each usage model specify: • Number of STA • For each STA: • List applications running on that STA • e.g. STA1 (HDTV), STA2 (backup), STA3 (email + web browsing + interactive video). • Channel model type & Range of BSS • e.g. Domestic, NLOS, 20m Adrian Stephens, Intel et al

  9. Other model details • STA are distributed randomly (uniform distribution) within BSS defined by usage model range • Measurements performed over at least 5 minutes of run time • Measurements to be averaged over TBD multiple random STA position configurations Adrian Stephens, Intel et al

  10. Where do we go from here? • A special committee is proposed to develop a usage model using the methodology described here. • Major decisions will always be taken by the TG, but we don’t have time to debate each of the parameters in a usage model. • Contributions are solicited from members to: • share results of research between meetings • coordinate presentations on usage models • with the aim of providing the unknowns in the current framework • Straw Poll for interest.
