Title: A group communication model for distributed real-time causal delivery

Yet delay jitter, and the absence of global clock may disrupt these temporal relationships. This paper proposes a hierarchical architecture of k-local groups, where k represents the number of local groups composing the distributed system G. Each local group is defined as a finite set of processes. The proposed architecture allows us to solve the local clocks drift by synchronizing the local clocks. The clocks synchronization is resolved by according to a time reference noted VMT (virtual master time). This hierarchical topology ensures real-time causal ordering, and guarantees a dynamic reconfiguration, in a failure detection, by insuring at least a partial real-time communication between alive local groups.Read More
