摘要：The Fair-Order Service of the present invention delivers action messages to theserver as soon as it is feasible. Because action messages from different players exhibit
different reaction times with respect to an update message, the Fair-Ordering Serviceexecuted at the server dynamically enforces a sufficient waiting period on each actionmessage to guarantee the fair processing of all action messages. In reality, the waitingperiod at the server is bounded because of the real-time nature of interactive games. Thealgorithms that offer Fair Ordering Service take into consideration delayed and out-of-order action messages. When action messages corresponding to multiple updatemessages are interleaved, the Fair-Ordering Service matches the action message to theappropriate update message. It accomplishes this by maintaining a window of updatemessages and using the reaction times for an action message for each of the updatemessages in the window. This enables state changes at the game server to be performedwith fairness to all the players. The Fair-Order Service invention is based on a frameworkthat uses a proxy architecture making it transparent to any specific game application. Theservice is well suited to client-server based, online multi-player games, where a fair orderof player actions is critical to the game outcome.
