| Abstract: | First we discuss the application of Ethernet and real-time promoting approaches for it,and then propose the technology of constructing the real-time Ethernet（RTE） based on RTLinux from studying three factors that give rise to communication delay.The critical technology implementations of RTE based on RTLinux,including multi-queue data exchange mechanism,buffer management mechanism based on address mapping and small-frame mechanism,are described in detail. |
