Abstract: A troubleshooting method includes sending a forward detection message to at least one node on a path to be detected. The forward detection message carries information about a forward path to be detected and information about a backward path to be detected. Faults are detected according to a backward detection message returned by the at least one node.

Abstract: Embodiments of the present invention provide a label-based measurement method, apparatus, and system. The method includes: allocating at least two labels to the same FEC; obtaining a label insertion mode for the at least two labels; receiving data packet, where one of the at least two labels is inserted in the data packet; and performing, according to the label insertion mode and the data packet, performance measurement on a network that the FEC passes through. By using the technical solutions provided in the embodiments of the present invention, a problem of network bandwidth occupation caused by inserting a test packet and an OAM packet during performance measurement and a problem of measurement result inaccuracy caused by OAM packet loss may be solved.
