1. A method for dynamic traffic routing in a communication network, the method comprising the steps of:

  • offering, initially, calls between an origin switching node and a destination switching node to at least one preferred path;

    offering calls to alternative paths contained in a path fan according to a selection scheme if none of the preferred paths is available;

    removing an alternative path previously contained in the path fan from the path fan as soon as, upon offering of a call, it is determined that it is no longer available;

    registering a chronological sequence by which the alternative paths are removed from the path fan; and

    reinitializing the path fan after at least one of an introduction of a particular event and a fulfillment of a particular condition by refilling the path fan with previously removed alternative paths, wherein the path fan is refilled with the alternative paths that, according to the chronological sequence, have already been removed from the path fan for a longest period of time.
