"Embedded Linux developer Lineo Inc. has released for beta testing RTnet, a modification to the Linux networking subsystem that permits embedded devices to communicate in hard real time using Internet protocols over Ethernet. According to the company, this represents the first time that such communications have been possible using nonproprietary operating systems."

"We wanted to extend the hard real-time ability from a single system to a distributed processing environment," said David Beal, product marketing manager for real-time solutions at Lineo. "RTnet allows you to [use] one computer to collect the information and another to act on it." The technology uses standard 10/100 Ethernet on a dedicated network, Beal said, and supports several popular Ethernet card brands, including 3Com."

"According to Lineo, RTnet supports IP, ICMP and UDP protocols, and provides real-time tasks with an implementation of sockets, including an interface nearly identical to the standard Linux UDP sockets interface. The report said that RTnet is expected to communicate with existing network stacks and works with Linux 2.2.x kernels and with both RTAI 1.3 and RTLinux 2.3."
