This invention relates to routing in a communication network. In particular, the invention concerns routing in telecommunication and cellular networks. The idea of the invention is to preprocess the network in order to accelerate the routing process. The preprocessing comprises finding the difficult network portions, and removing trivial network portions from the network topology. As a result of these phases the network is divided into small subnetworks. After the preprocessing predetermined endpoints of a single route are added into the subnetworks for finding the route through the network. After that, traffic in each subnetwork is routed separately. Traffic in the network parts between the subnetworks, or between the endpoints and the subnetworks, may need additional routing. |
