<p>A method, system and device for single-fiber bidirectional ring network protection are disclosed in the present invention, where a working path ring between each node in the single-fiber bidirectional ring network shares a sharing protection path using predefined wavelength, when a working path between two nodes fails, the method includes: controlling sharing protection devices of the receiving end node and the transmitting end node of the failure working path to switch from a primary port to a corresponding standby port, controlling an intermediate node in the sharing protection path corresponding to the working path to activate a standby port of the corresponding sharing protection device, and establishing the sharing protection path corresponding to the working path; transmitting the service signal borne in the failure working path through the sharing protection path. The method enables the working path ring sharing the protection path, thus saving the wavelength resources of the system significantly.</p> |
