Abstract

A new token-passing algorithm called AR-TP for avoiding the non-determinism of some networking technologies is presented. This protocol—based on RT-EP, a research protocol also based on transmission control techniques—allows the schedulability analysis of the network, enabling the use of standard Ethernet hardware for Hard Real-Time behavior while adding congestion management. It is specially designed for High-Integrity Distributed Hard Real-Time Systems, being fully written in Ada and taking advantage of some of the new Ada 2005 features, like the Ravenscar Profile.
