Abstract: Provided are a path protection method, a node device, a controller, and a storage medium. The path protection method used for a control panel of a node device includes acquiring a primary path and at least one standby path and sending the primary path and the at least one standby path to a forwarding plane according to a preset path protection control policy such that in response to the failure of the primary path, the forwarding plane switches a service to one standby path among the at least one standby path directly. The primary path and the at least one standby path are sent to the forwarding plane simultaneously. If the primary path fails, the forwarding plane switches to the standby path directly.
