Abstract: The backup-in-the-middle primary-backup configuration is created by placing a backup-in-the-middle forwarder in the routing path between the primary and the environment. The backup-in-the-middle forwarder intercepts output messages along with required state information sent by the primary to the environment. The backup-in-the-middle forwarder backs up the primary by updating its state information and forwards the output packets to the environment.
