Abstract:
A method of routing a call in a network having a plurality of nodes interconnected by trunks, the method comprising:calculating costs of different routes for taking the call, with selection between routes being a function of cost, where the cost of a route is a function of the passband available on the trunks constituting the route, the resources available on said trunks, and the sum of the costs of the trunks constituting the route; the cost of a trunk being a vector having a first component which is a function of the bandwidth available on the trunk and another component which is a function of the resources available on the trunk; wherein a constant value is defined when the available trunk resources exceed a given value, thereby limiting a number and frequency of repeated route calculations performed; and wherein the cost of a route is also a function of the bandwidth required for the call.
