摘要
对防火墙技术中使用的传输层驱动程序接口(TDI)过滤技术进行了分析,阐述了程序设计中的关键技术。给出了在TDI设计中应用程序的上网通告,内存的分配和释放在Windows下的实现流程及源代码。在对传输层驱动接口程序的性能分析的基础上,提出了改进驱动性能的优化方案,并对驱动开发过程的错误处理等技术在进行了说明。
Through careful analysis of the transport driver interface in firewall,this paper telles of the key technologies in the design of transport driver interface program,and gives the source code of the interaction and information transfer between the application layer and the driver,including the memory of the distribution and release.And based on analysis of TDI capability,it proposes the optimal scheme for the improvement of driver performance,and discusses some technologies for error handling in the process of driver development.
