1. A method for adaptive routing in a communication network having a plurality of mutually connected network nodes wherein network data relating to network topology of the communication network are maintained in each of the network nodes, comprising the steps of:

  • depending on said network data, individually creating according to defined optimization criteria routing tables for connection paths to all remaining network nodes that are possible destination nodes;

    if an event that influences the topology of the communication network occurs, updating network data maintained by a network node detecting said event, and transmitting a broadcast message corresponding to the event to all other network nodes;

    following reception of said broadcast message, updating with respective network nodes the network data maintained in the respective network nodes; and

    for transmission of said broadcast message within the communication network, defining a connection path network from a plurality of possible connection paths between the individual network nodes, the broadcast message reaching the respective network node via said connection path network and via only a defined restricted plurality of independent connection paths.
