Distributed object-oriented real-time simulation of the multicast protocol RFRM
Yoo Suk Hong · 2003
A real-time fault-tolerant multicast protocol is necessary for obtaining high performance in operating distributed real-time computing systems. This paper shows the efficiency of the RFRM (Release-time based Fault-tolerant Real-time Multicasting) protocol, which is based on the idea of attaching the official release time to each multicast message. As a part of this, a real-time simulation based on the TMO (Time-triggered Message-triggered Object) structuring scheme is conducted in order to evaluate the proposed approach. We experiment with a real-time multicast model which does not receive ACK messages, with the purpose of reducing the message traffic on the network by employing a fault detection mechanism. Simulation results promise good efficiency for the proposed real-time multicast protocol.
