Patent

CA 2157144

The communication network has a plurality of mutually connected network nodes (NR1,...,NK5), in which in each case network data relating to the network topology of the entire communication network are maintained and, depending on said network data, routing tables for connection paths to all remaining network nodes are created. If an event that influences the network topology of the communication network occurs, on the one hand the network data maintained therein are updated by the network node detecting said event. On the other hand a broadcast message corresponding to the event is transmitted to the other network nodes, following the reception of which the respective network nodes update the network data maintained therein. It is provided here that, for the transmission of the broadcast message within the communication network, a connection path network is defined from the plurality of possible connection paths between the individual network nodes, via which network the broadcast message reaches the respective network node via only a defined number of independent connection paths.
