Abstract
A method automatically discovers a topology of a communication network ring. The ring includes a plurality of nodes. Each node includes a first port and a second port. A ring topology request or a response to the ring topology request is received from at least one node on the ring. The ring topology request or the response to the ring topology request includes an identification of the at least one node and an indication of a hop count needed to reach the at least one node. The ring topology request or the response to the ring topology request is forwarded to at least one neighboring node on the ring through the first port. The topology is determined based on the identification of the at least one node, the hop count, and an identification of the first port.
