1. A method comprising:

  • receiving, by a computer system, information regarding a flow to be admitted to a network, the flow being associated with a source and a destination;

    for a shortest path in a plurality of paths between the source and the destination, calculating, by the computer system, a projected utilization of the shortest path in view of the flow;

    if the projected utilization of the shortest path is less than or equal to a target utilization threshold, assigning, by the computer system, the flow to the shortest path;

    else if the projected utilization of the shortest path is greater than the target utilization threshold;

    selecting, by the computer system, another path in the plurality of paths distinct from the shortest path based on one or more selection criteria; and

    assigning, by the computer system, the flow to the selected path.
