Program for managing failure in a network of nodes based on an overall strategy

Disclosed is a failure management method in a network of nodes (21-73), the method including, for each node (21-53) considered within all or part of the nodes (21-73) of the network performing the same calculation: firstly, a step of locally saving the state of this considered node (21-53) to a storage medium (31-56) for this considered node (21-53), wherein the link between this node storage medium (31-56) and this considered node (21-53) can be redirected from this storage medium (31-56) to another node (21-73), then, if the considered node (21, 42) is faulty, a step of retrieving the localbackup of the state of this considered node (21, 42), by redirecting the link between the considered node (21, 42) and its storage medium (22, 45) in order to connect the storage medium (22, 45) to anoperational node (23, 43) different from the considered node (21, 42), the local backups of these considered nodes (21, 53) used for the retrieving steps being coherent with each other to correspondto the same state for this
