Adaptive routing control method. |
摘要 |
<p>In a telecommunications network in which a plurality of switching nodes (N1 to N6) are interconnected via links (L12, L23) each composed of a plurality of trunks and are each connected to a network control center (NC) via a control signal link (C1 to C6), the network control center determines for each switching node a predetermined number of alternate routes for each first route on the basis of traffic data in the telecommmunciations network and supplies them as a set of available alternate routes to the switching node. The switching node assigns one or more of the available alternate routes in advance. The switching node responds to a call-connection request to try to connect the call to the first route, and when having failed in the call-connection, the switching node retries the call-connection through one of the assigned routes.</p> |
