ABSTRACT:
A communications network determines for itself its own network topology, that is, the identity and interconnection of nodes comprising the network. The network comprises a plurality of nodes each having at least one port. The ports are interconnected in accordance with the network topology in which communication traffic is conveyed over the network via the interconnected ports. Each port is arranged to transmit first information within the communication traffic including the identity of the port (Section trace identity) from which the communication traffic originates. Second information is transmitted between nodes identifying which first information identity relates to which node and which port. A processor is operative for determining for each node from the first and second information the identity of adjacent nodes and the identity of the ports to which its ports are connected.
