A method, system, device and computer program product for automatically detecting a topology of a local area network, LAN. The LAN may be included in a telecommunication node, e.g. a base transceiver station. The LAN includes a central host and further hosts connected to the LAN. The central host sends topology descriptors to the hosts connected to the LAN, the hosts each reporting at least one of the received topology descriptors and other information to the central host. The central host can thus build up a topology data base describing the network topology. The topology descriptors are sent in broadcast frames to the hosts. A host, after having received a topology descriptor, may create one or more dedicated addresses, e.g. from the topology descriptor, and return the address(es) to the central host which may store the address(es).
1. A method, comprising:
sending, in broadcast frames, at least one topology descriptor from a central host to at least one further host;
filtering, by at least one switch, the broadcast frames containing the sent at least one topology descriptor in such a way that only frames dedicated to a certain host reach, or are processed by, that host, wherein a frame dedicated to a certain host is a frame containing at least one topology descriptor describing the port number of the switch to which that host is directly connected;
receiving, at the at least one further host, the at least one topology descriptor sent in frames dedicated to the at least one further host;
reporting, from each of the at least one further host, the received at least one topology descriptor to the central host;
building up, at the central host, a topology data base describing the network topology based on the reported received at least one topology descriptor.
