Abstract: A method for selecting routing paths of data packets in a data network including plural communication links and routing apparatuses. The method includes: calculating and assigning to the communication links respective communication links' costs; calculating, for at least two different routing paths, respective routing path overall costs, which depend on the communication links' costs assigned to communication links making up such routing path; selecting, among the at least two different routing paths, the routing path having the lower routing path overall cost; causing a new data packet to be routed in the data network over the selected routing path, and collecting measures indicative of at least one performance parameter indicating a performance of previous transmissions of data packets from origin end points of the data network to destination end points of the data network, and using the collected measures for calculating the communication links' costs.
