Quorum-based protocol for group communication
Katsuya Tanaka, H. Higaki, Makoto Takizawa · 2003
Objects in distributed systems are replicated to make the systems fault-tolerant. Traditional group protocols support the ordered delivery of messages transmitted in the network. Only messages significant for the applications should be causally ordered in order to reduce the computation and communication overheads. In this paper a precedent relation among messages is for replicas which are locked in a quorum-based scheme. We discuss a group protocol which supports the precedency.
