Group Membership Management Protocol for the Cluster Checkpoint

In order to tackle the issue of keeping the consistent member view among the cyclic backup-based cluster checkpoints, a group membership management protocol is proposed for the cluster checkpoints with the precondition of the reliable communication among cluster nodes.Roles in the group and the member view is defined, and a set of protocols for the checkpoint member joining, quitting and failure are designed.Key issues in the implementation of the group membership management protocol are discussed.Experimental results show that the protocol costs a little overheads and is proved to be efficient.
