提出了一种用于维护复制数据的协议，该协议可以提供高数据可用性和低响应时间。现有协议的设计主要是通过更新大部分副本来实现高可用性，这提供了一些（尽管不是很重要）负载共享。在新协议中，事务处理在存储数据副本的节点之间有效地共享，事务的响应时间和系统吞吐量都得到了显著提高。本文还分析了新协议的可用性，并通过仿真研究了负载分担对事务响应时间的影响。并将新协议与基于投票的方案进行了比较
A protocol for maintaining replicated data that can provide both high data availability and low response time is presented. Existing protocols are designed primarily to achieve high availability by updating a large fraction of the copies, which provides some (although not significant) load sharing. In the new protocol, transaction processing is shared effectively among nodes storing copies of the data, and both the response time experienced by transactions and the system throughput are improved significantly. Also presented is an analysis of the availability of the new protocol and simulation is used to study the effect of load sharing on the response time of transactions. The new protocol is also compared with a voting-based scheme.<<ETX>>
