Abstract:
A network-structured telecommunications network comprising switches and data transmission connections therebetween, where at least a certain number of the switches are arranged to control the routing of the connections in the telecommunications network according to a plurality of predetermined tree topologies, characterised in that each of the certain number of switches belonging to said plurality of predetermined tree topologies is arranged to serve as an anchor node of the plurality of predetermined tree topologies during routing and that a subset of the certain number of switches are provided with functions supporting wireless terminals,wherein each of the certain number of switches is arranged to choose, in the beginning of the routing controlled by said switch, a tree topology to be used in said routing, and wherein each of the switches belonging to the certain number of switches is arranged to choose, in the beginning of the routing controlled by said switch, the tree topology to be used in said routing, according to which tree topology's centre point is located nearest to the switch in question.
