摘　　要：如何提高网络通信的可靠性和实时性已成为一个重要问题。目前在WindowsNT中普遍采用应用程序网络接口进行网络编程,它运行在操作系统的应用层,在Windows系统的抢先多任务调度机制中,运行等级低,容易受到系统任务调度的影响,因此无法满足工程中严格的可靠性和时间性要求。文中探讨了在WindowsNT下开发核心层网络通信程序的途径和方法,使用DeviceDriverKit(DDK)开发核心层网络通信程序,提高网络通信的运行等级,从而提高了它的可靠性和实时性。How to improve the reliability and realtime accuracy of network communication is becoming a significant issue. Nowadays, application network interfaces are used very widely under Windows NT, but those programming interfaces are running in the application layer of the operating system, whose priority is rather low. The reliability and real-time accuracy can not be guaranteed. The method of developing network driver under Windows NT is introduced in this article. It enhances the running priority of the network communication so that its reliability and realtime accuracy can be improved greatly.
