Abstract

Traffic measurements and network management controls are applied in an exchange in real-time on a per-route basis. Selection of an idle circuit between two exchanges is done by first selecting a route and path based on a route busy/idle status map, a source destination restriction map defining restriction on a route for certain sources, and a second connection map defining availability of a second link in a two link connection. A circuit group busy/idle map for a selected route is consulted to find an idle circuit group and finally, a circuit is selected from a circuit group which is known to have at least one idle circuit. Traffic measurements, including measurements of attempts, seizures and answers are recorded on a per-route basis with a specific indication as to the source of the traffic in the event of a direct route. Traffic measurements are also made to record traffic routed to an alternate route and the identity of the alternate route as well as traffic received as alternate route traffic from another route together with the identity of that route. Data defining routes and alternate routes which have a low completion rate are identified and network management controls are automatically applied to the routes for affected destination codes. Circuit reservation levels are defined which allow the selective control of alternate or direct traffic on a route based on the number of idle circuits in a route.
