Abstract
The invention relates to a method of fault management in a network of nodes (), comprising, for each node considered () of all or part of the nodes () of the network performing one and the same calculation: firstly, a step of local backup of the state of this node considered (), at the level of a storage medium () for this node considered (), the link () between this storage medium () and this node considered () being able to be redirected from this storage medium () to another node (), thereafter, a step of relaunching: either of the node considered () if the latter is not defective, on the basis of the local backup of the state of this node considered (), or of an operational node () different from the node considered (), if the node considered () is defective, on the basis of the recovery of the local backup of the state of this node considered (), by redirecting said link () between the node considered () and its storage medium () so as to connect said storage medium () to said operational node (), the local backups of these nodes considered (), used for the relaunching steps, are mutually consistent so as to correspond to one and the same state of this calculation.
