ABSTRACT:
An asynchronous transfer mode (ATM) network or the like employing a method and apparatus for automatically determining the topology of the network is described. The method and apparatus provides for each switch in the network transmitting on each of its ports link advertisement messages (without processing intervention by intermediate switches). The link advertisement messages are received by neighbor switches and forwarded to a topology manager. The topology manager constructs network topology profile information based on received link advertisement messages. Further, the topology manager is able to verify bidirection links based on the received link advertisement messages.
