I want to know a few things like how have you implemented the repeated migration of VM checkpoints from primary to backup, whenever backup receives the checkpoint, it sends an acknowledgement, the primary receives this acknowledgement and send a output release signal, Can you shed some light on how these things are implemented. how the backup detects that t received a checkpoint and it send an acknowledgement now?
