The present invention relates to the field of network communications and specifically discloses a method for establishing a restoration path. The method includes: obtaining, by a first node, a working forward-shared node set of a restoration path according to route information of the restoration path and a working path of a service; determining, by the first node according to the working forward-shared node set, whether the first node is a working forward-shared node, and allocating a first label and a first interface; sending, by the first node, an establishment request message to a first downstream neighboring node, where the establishment request message includes at least the first label, the first interface, the route information of the restoration path, and working forward-shared node information; receiving, by the first node, an establishment response message of the restoration path, where the establishment response message includes at least a fourth label, a fourth interface, and the route information of the restoration path; and establishing, by the first node, a cross-connection of the restoration path according to the first label, the first interface, the fourth label, and the fourth interface. Embodiments of the present invention further disclose a system and a node device for establishing a restoration path. |
