摘要：In this paper, we have addressed the complex problem of determining a recovery line for cluster federation and proposed an efficient checkpointing / recovery mechanism for it. The main objective of the proposed approach is to advance the recovery line in a cluster federation such that we can put a limit on the amount of rollback by the processes in all the clusters in case of failure(s) in the cluster federation; thereby in the worst case only limited domino effect is allowed in our work. In this approach, processes in different clusters are able to perform their responsibility independently and simultaneously. This inherent parallelism of the algorithm contributes to its speed of execution. We have shown that the proposed approach is superior to the existing works, because neither it suffers from any message storm, nor it takes any unnecessary checkpoints.
