Process and routing system for dynamic traffic control in a communication network
First Claim
Patent Images
1. A process for dynamic traffic control in a communication network, comprising the steps of:
- initially offering calls between an origin switching node of the communication network and a destination switching node of the communication network to at least one planned route;
offering calls, in the event that none of the at least one planned route is available, to alternate routes, which are contained in a route fan, based on a predetermined selection scheme;
removing an alternate route, previously contained in the route fan, from the route fan as soon as it is established that said alternate route is no longer available;
reinitializing the route fan if the number of alternate routes contained in the route fan drops below a value;
removal of the alternate route from the route fan not being restricted to an individual time for this alternate route; and
reinitializing the route fan if a predetermined time condition is satisfied.

Abstract
The dynamic routing of a communication network is to adapt itself to the respective traffic load in the network in a way which optimizes network throughput. The routing according to the invention solves this problem by a route fan for holding alternate routes for the overflow traffic, an alternate route previously contained in the route fan being removed from the route fan without replacement as soon as it is established that it is no longer available.

9. A routing system for dynamic traffic control in a switching node processor of a communication network, the routing system having a structure comprising:
-
the system offering calls between an origin switching node and a destination switching node of the communication network initially to at least one planned route; the system offering, in the event that none of the at least one planned route is available, calls to at least one alternate route, which are contained in a route fan, based on a specific selection scheme; the system removing the alternate route previously contained in the route fan from said route fan as soon as the alternate route is no longer available; the system reinitializing the route fan if the number of alternate routes contained in the route fan drops below a predetermined number; the system not restricting removal of an alternate route from the route fan to an individual time for this alternate route; also the system reinitializing the route fan if a predetermined time condition is satisfied. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)
