2 Gaming Traffic Model Problems: –Games in the different genre, such as First Person Shooter (FPS), Role Play Game (RPG), etc., show dramatically different traffic behaviors. Thus, single traffic model can’t represent the different characteristics of various gaming genres. The current counter strike game modeled in 16m draft is a subtype of FPS genre. Proposed Solution: –Use different gaming traffic models for different gaming genres Each genre can be generalized into one model. Scope of this Proposal –The current proposal covers only FPS game genre. –The decision is to not include RPG traffic model in the Evaluation Methodology because it does not post additional requirements to the system performance.

4 Compare the Draft 802.16m Gaming Packet Size Distribution with Real-time Trace Data (DL) Largest extreme value distribution (LEVD) is a reasonable fit for gaming packet size distribution We observed that for the FPS game, the forward link packet size has significantly larger a and b values than the gaming model specified in the draft 802.16m Evaluation Methodology Document, where a = 120 bytes, b = 36. Proposed Parameter Values –a = 330 bytes, b = 82. DraftTrace a120330 b3682 LEVD Distribution Parameters

5 Compare 802.20 Gaming Packet Inter Arrival Time Distribution with Real-time Trace Data (DL) Largest extreme value distribution (LEVD) is a reasonable fit for gaming packet inter arrival time distribution We observed that for the FPS game, the forward link packet inter arrival time has slightly lower a and b values than the gaming model specified in the draft 802.16m Evaluation Methodology Document, where a = 55 ms, b = 6. Proposed Parameter Values –a = 50 ms, b = 4.5 DraftTrace a5548 b64.5 LEVD Distribution Parameters

6 Compare 802.20 Gaming Packet Size Distribution with Real-time Trace Data (UL) Largest extreme value distribution (LEVD) is a reasonable fit for gaming packet size distribution We observed that for the FPS game, the reverse link packet size fits well in the draft 802.16m Evaluation Methodology Document, where a = 45 bytes, b = 5.7. Proposed Parameter Values –No change is necessary DraftTrace a45 b5.7 LEVD Distribution Parameters

7 Compare 802.20 Gaming Packet Inter Arrival Time Distribution with Real-time Trace Data (UL) Largest extreme value distribution (LEVD) is a reasonable fit for gaming packet inter arrival time distribution We observed that for the FPS game, the reverse link packet inter arrival time also follows LEVD. Instead of using deterministic, 40ms, as in the draft 802.16m Evaluation Methodology Document, we propose 802.16m to use –a = 40 ms, b = 6 DraftTrace Deterministic40ms aN/A40ms bN/A6 LEVD Distribution Parameters
