Abstract:
A switched telecommunications network connected to a plurality of carrier networks, said switched network having at least one switch for routing a call to a desired destination via a selected carrier network according to a routing table in each switch, wherein said switched network has call routing data management means comprising:means in the switched network for monitoring a plurality of operational performance parameters for each of the carrier networks; means in the switched network for automatically determining a routing table for each switch in the switched network based, at least in part, on the monitored operational performance parameters of the carrier networks; means in the switched network for determining that a monitored operational performance parameter for one of the carrier networks has changed; means in the switched network for automatically updating the routing table in each switch upon determining that a monitored operational performance parameter for one of the carder networks has changed; and means for selecting a carrier network and controlling each switch according to each switch's determined routing table to route the call to the selected carrier network based, at least in part, on the monitored operational performance parameters of the carrier networks.
