摘要

Highly available services can be implemented by means of so-called quorum protocols. Unfortunately, applying quorum protocols in real-world physical networks turns out to be difficult since efficient quorum protocols often depend on a particular graph structure imposed on the replicas managed by it. In this paper, we show that the cost and availability predictions of the operations provided by quorum protocols are often not accurate when they are executed in a real-world physical network. We present the mapping approach, the mapping approach increases the accuracy of the cost and availability predictions of most quorum protocols on real-world networks. Additionally, we use this mapping approach to analyze the resulting operation availability of two commonly known quorum protocols when applied to a physical network.
