A message passing protocol for small-scale distributed real-time systems

In distributed real-time systems, every node is usually responsible for performing pre-assigned local activities that are required for its physical environment. Nodes are connected via high-speed communication links and information flow is made possible by using message-passing techniques. Reliability, in-time delivery of messages, priority support, and fault-tolerance are amongst the requirements for such systems. Current Techniques lack all or most of these requirements. This is because they are general-purpose techniques and not tailored to match specific requirements needed by small-scale distributed real-time systems. In this piper, the Round Data Mailer technique is further studied and a layered protocol is proposed.
