摘　　要：在一些安全关键系统中,对数据通信的实时性要求非常严格。为了满足Linux操作系统下硬实时数据通信的要求,在对Linux内核进行实时化改造的同时,使用RTnet对通信协议栈进行了实时化改造。针对RTnet协议栈TDMA的特性搭建了测试平台,设计了数据传输时延测试。测试结果表明,采用RTnet实时化改造后的网络数据传输时延显著降低。In some security-critical systems,the real-time requirement of data transmission is very strict.To meet the requirement of hard real-time data transmission in Linux operating system,the real-time transformation of Linux kernel is carried out first,then the real-time transformation of communication protocol stack is carried out by using RTnet.A test platform is built according to TDMA character of RTnet and a test procedure is designed for data transmission delay.The test results show that the network data transmission delay is significantly reduced by using RTnet.
