摘　　要：针对传统记录重演方法存在同报文格式相关、需要被控程序紧密配合及数据传输效率低等问题,提出了一种基于数据截获与欺骗方式实现的通用记录重演解决方案。首先,利用Winsock2服务提供者接口技术,实现了网络数据的自动截获;其次,采用内存映射文件技术解决了数据共享和高速存取问题;最后通过向用户程序发送伪消息激发其读数据动作,完成数据注入。实际应用表明,新方法避免了数据的网络传输,无需被重演程序配合且与系统报文无关,能够完成10倍速度的流畅重演,普适于分布式仿真与模拟训练系统。For the problems of the traditional method of data record-replay, such as packet format association, close corporation with the controlled application, and low transmission efficiency, a new record-replay method based on data interception and cheating injection was proposed. Firstly, the network data packet was automatically intercepted through the service provider interface technique of Winsock 2. Secondly, the problem of the data sharing and high speed data access was solved by using the memory-mapped file technique. Finally, the saved data packet was intercepted into the user program by the data read operation motivated by the fake messages. The practical application shows that the new method is suitable for the distributed simulation and simulated training system for its merits such as the avoidance of network packet transmission, no necessity for corporation with the controlled application, irrelevance of the packet format, smooth recurrence with ten times the speed.
