Projects / RTnet


RTnet is an hard real-time network protocol stack for Xenomai and RTAI (real-time Linux extensions). It makes use of standard Ethernet hardware and supports several popular NIC chip sets, including Gigabit Ethernet. Moreover, Ethernet-over-1394 support is available based on the RT-FireWire protocol stack. It implements UDP/IP, ICMP, and ARP in a deterministic way and provides a POSIX socket API to real-time user space processes and kernel modules.
