Expansion of internet and construction of high speed network which require multimedia services like MMORPG are exceeding the infra-structure. In this work, CBT is analyzed by focusing on the multicast routing protoco and the algorithm which is transformable to Anycast scheme from CBT scheme is suggested to adapt game traffic. Anycast routing scheme is suitable to distribute high density traffic. Simulation model was set per a number of group and group member, which enabled to reflect real environments. Performance evaluation of routing based on the characteristics of end-to-end delay of CBT and Anycast was mainly focused, The result showed that Anycast method was improved up 8.7%, 25.5%, 34.0%, 38.6% and 51.8%, 56.6% comparing with PIM-DM and CBT routing when packet site was 128, 512 and 1K byte respectively. From the simulation, CBT/Anycast routing scheme can be presented as a flexible and solid solution for the MMORPG traffic to improve the delay characteristics of game packets.
