Based　on　the　reason　of　network　synchronization　and　the　existing　synchronization　mechanisms,　this　article　adopts　the　idea　of　message　partition,　IOCP　and　the　thread　pool　technology,　improves　Time　Warp　algorithm　and　Dead　Reckoning　Algorithm,　designs　a　integrated　solution　of　synchronization　between　server　and　client　to　mitigate　the　synchronization　problems　in　MMORPG.　In　the　experiment,　we　compare　and　analysis　the　effect　of　traditional　synchronous　solutions　and　the　effect　of　our　solution,　it　is　shown　that　this　system　can　better　solve　the　synchronization　problem　in　MMORPG.
