Group protocol for quorum-based replication
Keijirou Arai, Katsuya Tanaka, Makoto Takizawa · 2002
Distributed applications are realized by cooperation of multiple objects. Objects in the systems are replicated to make the systems fault-tolerant. Read and write request messages are issued to the replicas in a quorum based scheme. A quorum based ordered relation among request messages is defined to make replicas consistent. We discuss a group protocol which supports a group of replicas with the quorum based ordered delivery of request messages.
