摘要：

分布式协商的目的是在分布式环境下在一组进程之间决定一个共同的值，这是在分布式系统中最基本的问题。分布式协商问题的目标非常简单，但是在面对节点出错、网络出错、网络时延等环境的时候，协议设计以及处理起来十分困难。讨论分布式协商问题的基本形式，在不同的系统假设下的基本结果以及分布式协商在构建稳固的分布式大数据系统中的作用。

Abstract:

The goal of distributed consensus is quite simple i.e.how to decide a value among a group of coordinated processes in the distributed environment.However,the problem is turned out to be very difficult while facing the different distributed environment.The even harder problem is that some consensus protocols are hard to be implemented in practical systems.Some results of distributed consensus algorithms under different distributed environment assumptions were reviewed.In addition,some practical systems based on consensus for achieving high reliability were discussed.

Key words: distributed consensus, replicated state machine, network error, safety, liveness
