LAN TOPOLOGY DETECTION AND ASSIGNMENT OF ADDRESSES
First Claim
1. A method for detecting a network topology of a local area network, the local area network comprising a central host and at least one further host, the method comprising:
- sending topology descriptors from the central host to the at least one further host;
receiving a sent topology descriptor at the at least one further host;
each of the at least one further host reporting the received topology descriptor to the central host;
the central host building up a topology data base describing the network topology based on the reported received topology descriptors.

Abstract
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).

28. A system for detecting a topology of a node, comprising:
-
a local area network having a central host; and at least one further host connected to the local area network, wherein; the central host of the local area network is configured to send topology descriptors to the at least one further host connected to the local area network, the at least one further host is configured to report the received topology descriptor and/or other information to the central host, and the central host of the local area network is configured to build up a topology data base describing the network topology based on the reported information. - View Dependent Claims (29, 30, 31, 32, 33)

34. A host in a local area network, configured to:
send, when receiving one or more topology descriptors from a central host of the local area network, a reporting message to the central host, the reporting message containing at least one of; the received topology descriptor, all topology descriptors received by the host, the host type, and at least one computed address belonging to the host. - View Dependent Claims (35, 36, 37, 38, 39)

40. A central host in a local area network, configured to:
-
send topology descriptors to other hosts connected to the local area network, and to receive, from each of the other hosts, at least one of; the host type of the respective other host, the topology descriptor received by the respective other host, all topology descriptors received by the respective other host, and at least one address belonging to each respective other host, and wherein the central host is configured to build up a topology data base describing the network topology based on the received information. - View Dependent Claims (41, 42)
