Abstract
The present invention discloses a method including the steps of a) confirming the status of a path corresponding to each node apparatus in the ring network by using a predetermined control information that includes a function of adding/deleting a predetermined path on a physical layer, b) instructing each node apparatus to add/delete the predetermined path by using the predetermined control information when the status of the path corresponding to each node apparatus is confirmed to be normal, c) reporting completion of the addition/deletion of the predetermined path to each node apparatus by using the predetermined control information when the addition/deletion of the predetermined path is adequately performed by each node apparatus, and d) reporting the addition/deletion of the predetermined path to a ring application function included in the ring application of the data link layer when the completion of the addition/deletion of the predetermined path is adequately reported by each node apparatus.
