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.

Abstract: An asynchronous transfer mode (ATM) network or the like having a plurality of switches which may each be coupled with a central service provider over a virtual service path. Service requests, grants of service, and other control information for the network may then be communicated between each of said switches and the central service provider over virtual communication channels within said virtual service path. The disclosed method and apparatus provides for efficient communication of service requests and service grants without requirement to establish new communications paths between the individual switches and the central service provider for each request. Further, the ATM network may be managed by the central service provider as a logical star network.
