A method, node device, and system are disclosed for establishing a label switched path, which belong to the field of communications technologies. The method includes: receiving a connection establishment request message sent by a source node to a sink node, where the connection establishment request message carries bandwidth request information corresponding to different conditions, and each of the bandwidth request information corresponds to one condition; and reserving, according to the bandwidth request information corresponding to the different conditions, a corresponding bandwidth resource in subsidiary remaining bandwidth corresponding to the different conditions on a local link, thereby establishing a connection between the source node and the sink node. |
