1. A system comprising a set of equipment items, said equipment items comprising one or more nominal equipment items and one or more redundant equipment items, a redundant equipment item being associated with one or more nominal equipment items, the system comprising n channels linked to said equipment items, the channels linked to the equipment items being input or output channels of the equipment items,
the system comprising at least one redundancy matrix of n×m dimension configured to route the signals of a channel from a given equipment item to a redundant equipment item associated with said given equipment item or to another nominal equipment item, in response to the detection of a rerouting-triggering event relating to an equipment item, n and m each being a positive integer greater than or equal to one;
wherein each redundancy matrix is represented by a connection grid having a matrix representation comprising rows and columns, each row corresponding to a channel Ci,0≤i<n of the system and each column corresponding to an equipment item of the system, and in that the connection grid comprises a set of connection points corresponding to a point of intersection between a channel and an equipment item, said points of connection of the connection grid comprising at least:
all of the points of intersection of a nominal path comprising the points of intersection of the connection grid situated on a nominal diagonal of the connection grid, between each row corresponding to a channel of given index i and a column corresponding to a nominal equipment item of the same index i, and
all of the points of intersection of a redundant path comprising the points of intersection of the connection grid situated at the intersection between each row corresponding to a channel Ci of given index i and a column corresponding to a redundant element of index ƒ(i) such that the function ƒ is a defined surjective function of the set custom character0;n−1custom character on custom character0;m−n−1custom character for any index i,
the redundancy matrix being implemented in the form of a circuit comprising a plurality of switches arranged according to the connection grid.
