ABSTRACT:
A method and apparatus analyzes network topology data of a telecommunications network. Each physically diverse path in the network is assigned a unique path identifier. Trunks along each path, and ports at nodes through which the trunks are routed, are assigned the corresponding path identifier. If a trunk fails, the ports facing the point of failure issue alarms that include the corresponding path identifier for the trunk. A computer or other system compares the path identifiers of the alarming trunks with the path identifiers of restoral routes, such as other trunks extending between end nodes at opposite ends of the failure. Only those trunks having path identifiers differing from the path identifier of the alarming trunk are selected as possible restoral routes for the failure.
