Abstract:
1. A communications network, comprising: a plurality of nodes each having at least one port, the ports being interconnected in accordance with a network topology in which communication traffic comprising synchronous traffic frames is conveyed over the network via the interconnected ports, each port having a unique port identifier, each node having a unique node identifier, each port being operative for transmitting within a section overhead of the communication traffic the port's respective port identifier identifying the port from which the communication traffic originates, the information transmitted in the section overhead being insufficient to determine the identity of the node from which the communication traffic originates, means for transmitting to each node information, including for each node of the network, the node identifier and the port identifier for each port associated with the node, and processing means for determining for each node from the received port identifier and the information, an identity of an adjacent node and an identity of the port to which its ports are connected, at least one of the nodes comprising a memory for storing the determined identities.
