Massively multiplayer online games (MMOGs) have gained enormous popularity amongst the game communities, industries and academic researches. In particular, first person shooter (FPS) and massively multiplayer online role-playing game (MMORPG) genres are most famed. FPS traffic is very delay sensitive like voice and its interactivity is similar to the multimedia. However, MMORPG traffic is less delay sensitive than FPS, nevertheless, FPS traffic is more packet loss ratio tolerant than MMORPG. To address the low latency, packet loss and large bandwidth requirements of those game genres, Ethernet passive optical network (EPON) would be an eminent election amongst broadband access networks. In this paper, we introduce an enhanced EPON architecture, a new queue scheduling mechanism to queue the FPS and MMORPG separately, and a game dynamic bandwidth allocation (Game DBA) to assign bandwidth to FPS and MMORPG and guarantee an overall QoS metrics based on the games requirements. The proposed Game DBA is capable to delay MMORPG traffic for some cycle, in which users do not sense this delay. Simulation results have illustrated that our proposed architecture can improve the games quality of service (QoS) in terms of mean packet delay and packet loss ratio.
