Viewstamped Replication Revisited
Barbara H. Liskov, James Austin Cowling · DSpace@MIT (Massachusetts Institute of Technology) · 2012
This paper presents an updated version of Viewstamped Replication, a replication technique that handles failures in which nodes crash. It describes how client requests are handled, how the group reorganizes when a replica fails, and how a failed replica is able to rejoin the group. The paper also describes a number of important optimizations and presents a protocol for handling reconfigurations that can change both the group membership and the number of failures the group is able to handle. 1
