数据复制是提高大型分布式系统可靠性的一种很有前途的方法。混合数据复制协议结合了树仲裁协议和网格协议的概念。我们提出了一个分析评估的读/写可用性的广义混合数据复制协议，扩展到一个更一般的形式，以提高写可用性的节点的安排。在假设节点可能发生故障的情况下，还分析了为读/写操作访问的平均节点数。方程推导出基于节点的可用性p，数值例子。我们使用计算机模拟来估计吞吐量的读/写操作。
Replicating data is a promising way of improving the dependability of large distributed systems. The hybrid data replication protocol combines concepts of the tree quorum protocol and grid protocol. We present an analytical evaluation of read/write availability for the generalized hybrid data replication protocol, which extends the arrangement of nodes into a more general form to improve write availability. The average number of nodes accessed for read/write operations is also analyzed under the assumption that nodes might fail. Equations are derived based on node availability p, and numerical examples are shown. We use computer simulations to estimate the throughput for read/write operations.
