The embodiment of the invention provides a method for realizing Ethernet ring network protection in a TSN virtual network bridge. The method comprises the following steps: the TSN virtual network bridge deployed in an Ethernet ring network receives a mapping table of fault identifiers and TSN scheduling parameters issued by a TSN control management unit; the TSN virtual network bridge adjusts the TSN scheduling parameters in the mapping table into scheduling parameters of corresponding network elements in the TSN virtual network bridge, and issues the adjusted mapping table to the corresponding network elements; and when the corresponding network element receives a state notification message triggered when the Ethernet ring network has a fault, applying a corresponding scheduling parameter according to a fault identifier carried in the state notification message. In the embodiment of the invention, the mapping table of the fault identifier and the TSN scheduling parameter is issued to the TSN virtual network
