Abstract
A method, system, and network device for node configuration and path detection are provided. The method for path detection includes: receiving a path detection message, and writing path state information of a present node into the path detection message; forwarding the path detection message, into which the path state information of the present node has been written, to downstream nodes according to a forwarding manner for a multicast data stream. The method for path detection is capable of improving the acquisition efficiency for multicast paths and saving network bandwidth.
