Abstract
Embodiments of the present invention provide a method and a node for discovering topology structure automatically in a Multi Protocol Label Switching (MPLS) ring network. The method includes: when receiving a topology discovering message, determining, by a node in the MPLS ring network, whether the topology discovering message is sent by the node; if yes, updating information of topology structure of the MPLS ring network stored in the node according to information of topology structure of the MPLS ring network carried by the topology discovering message; otherwise, appending information of topology structure of the node to the topology discovering message and forwarding the topology discovering message to a next node. Thus, the network topology may not depend on the topology of the physical layer network and the speed of discovering topology structure of the ring network is increased.
