Abstract:
1. A method for ascertaining network topologies, the method comprising the steps of: transmitting a request message from a first network node to at least one second network node connected to the first network node; entering, via the second network node, an associated node number in the network into the request message; forwarding, via the second network node, the request message to at least one third network node connected to the second network node; forwarding the request message until all network nodes arranged in the network and all connecting lines connecting the network nodes have been passed through; transmitting the request message back to the first network node; and storing the network topology information available in the form of the node number entered in the request message; entering, via the third network node, an associated node number of the third network node into the request message again in cases in which the node number of the third network node already has been entered in the request message; and sending, via the third network node, the request message back to the second network node.
