The present invention discloses a network protection method and apparatus, an off-ring node and a system, and belongs to the field of communications. The method includes: obtaining service configuration information of the other off-ring node; when receiving service data, detecting whether service configuration information carried in the service data is matched with the service configuration information of the other off-ring node; and if a detection result is that the service configuration information carried in the service data is matched with the service configuration information of the other off-ring node, deciding that an off-ring policy of the service data includes: performing an off-ring operation of the service data at the current off-ring node, and/or sending the service data to the other off-ring node to perform the off-ring operation. According to the present invention, in the case where no dual-homing protection needs to be specially provided, but ring network protection is provided, a protection effect same as that of the dual-homing protection may be achieved. Moreover, since the dual-homing protection does not need to be deployed but the ring network protection is deployed, only one set of OAM based on the ring network needs to be operated, and thus very few OAM resources are occupied. |
