CALL ROUTING DATA MANAGEMENT

A switched network (1) for use in a telecommunications network comprising a plurality of networks (15a..15n), comprises at least one switch (3, 5) for routing traffic to a required destination via another network (9, 11) according to a routing table. The switched network (1) has call routing data management means including: means for monitoring a plurality of parameters associated with the other networks in t he telecommunications network; means for determining a routing table for each switch in said network based on the monitored parameters; and, means for controlling t he switch or switches according to the determined routing table. The switched network enables the optimal route to be used, and the dynamic nature of the invention means that upon an event occuring in an operational environment, the central call routing data management unit provides a mechanism for quickly assessing the impact of the change and if necessary, rapidly reconfiguring the network to accommodate the change.
