A procedure for sorting a plurality of circuit data flows (7, 8, ~) located, according to an initial configuration, in a plurality of sets of slots (space, time, frequency or wavelength) in a transport sub-network, comprising the following steps: -calculating a theoretical configuration in which flows are optimised in terms of occupied band by applying a theoretical flow routing algorithm; on the basis of the theoretical configuration defined above, exchanging the position of the flows in the sub-network slots to obtain an optimal arrangement which minimises the occupied slots; flows whose position corresponds to the position assumed by the flows in the initial position are identified to reduce the number of exchanges; defining and implementing a minimum shift sequence of single flows needed to shift each single flow from an initial position occupied in the initial flow configuration to a final position corresponding to the position assumed by the flow in the optimal slot set arrangement.
