Abstract:
A method, system and apparatus for single-fiber bidirectional ring network protection are disclosed in the present invention, wherein, one working path ring between various nodes in the single-fiber bidirectional ring network shares one sharing protection channel using a set wavelength, and when a fault occurs in a working path between certain two nodes, the method includes: controlling sharing protection apparatuses of a receiving end node and a transmitting end node of the failed working path to switch from a primary port to a corresponding standby port, controlling an intermediate node in the sharing protection channel corresponding to the working path to enable a standby port of the corresponding sharing protection apparatus, and establishing the sharing protection channel corresponding to the working path; transmitting a service signal carried in the failed working path through the newly established sharing protection channel.
