Distributed real-time simulation of the group manager executing the multicast protocol RFRM

Group communication in real-time computing systems is useful for building fault-tolerant distributed real-time applications. The purpose of this paper is to show the efficiency of the group membership manager executing the multicast protocol RFRM (Release-time based Fault-tolerant Real-time Multicast) which is based on the idea of attaching the official release time to each group view send message. In this approach, the group membership manager interacts with the fault detector and the client application do not send view-ack messages to the group membership manager. A real-time simulation based on the TMO structuring scheme is conducted to study its performance for both the proposed approach and the group management scheme which receives view-ack messages. Simulation results show that with a proper value of the official release time interval, our approach improves the delay in completing the group view change event
