1. A communication traffic routing apparatus comprising: a metric information collector operable 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 a plurality of different computed routes for a virtual connection toward a destination; and a selection module operatively coupled to the metric information collector and operable to select, from the different computed routes, based on the collected metric information, a route for a virtual connection toward the destination.
