1. A routing apparatus comprising:

  • a metric information collector configured to collect, from metric information generated by at least one remote route computation element that is capable of computing routes for virtual connections between the routing apparatus and other routing apparatus over an underlying communication system, metric information associated with each of a plurality of different computed routes for a virtual connection with a destination; and

    a selection module operatively coupled to the metric information collector and configured to select, from the different computed routes and based on the collected metric information, a route for the virtual connection with the destination, wherein the metric information associated with each of the plurality of different computed routes comprises information indicative of a weighted combination of cost and delay to reach the destination from the routing apparatus over each computed route.
