ABSTRACT:
The invention falls within the technology of multistage interconnection network such as fat-trees, comprising at least one switch located at a stage (s) and configured to send, through an output port from a number (k) of output ports forming an ordered list, at least a data packet containing a destination address identified by a n-tuple with a plurality (n) of components (pn−1, . . . , p1, p0), and sε{0 . . . (n−1)}. The invention has application for both source and distributed routing, as deterministic and as adaptive routing, selecting an output port to be the unique or the default option to forward the packets at the switch which is the output port that has a position in the ordered list of output ports corresponding to the component (ps) of the destination address at the position given by the stage (s) of the switch.
