摘要： 针对SCRIBE在解决基于P2P的巨量多玩家网络游戏兴趣域内多播时，产生的多播效率低、游戏状态数据同步性差问题，提出一种SCRIBE改进多播算法，该算法考虑P2P网络中终端节点在带宽和计算能力上的异构性，同时保证同一组中节点具有共同的兴趣。仿真结果表明，该算法能够在较大程度上减小消息冗余和降低多播延迟，提高游戏状态数据的同步性。

Abstract: Aiming at the question of low multicast efficiency and poor game states synchronization in the SCRIBE algorithm based on P2P for Massively Multiplayer Online Games(MMOG) Area Of Interest(AOI) multicast, an advanced multicast algorithm based on SCRIBE is presented. The algorithm mainly considers the P2P network terminal nodes in bandwidth and computing power on the heterogeneity and guarantees that all nodes have the same interest in the group. Simulation results show that the algorithm gains a greater improvement on reducing message redundancy and the latency of multicast and the synchronization of game states.

Key words: P2P network, Area Of Interest(AOI), SCRIBE algorithm, application-layer multicast
