The present invention discloses a linear protection method for an optical network, used for protecting a failed service path in the optical network, and the method comprises: setting priorities of services carried on service paths participating in linear protection of the optical network as service priorities; selecting, from the service paths participating in the linear protection, a service path of which the service priority is lower than that of the failed service path as a protection path, and bridge switching the service on the failed service path to the protection path. The present invention implements protection of service paths according to the priority of the service carried on the failed service path, and enhances the security of service paths.
