20120163166 | Ethernet Switch Ring (ESR) Protection Method And Transit Node - The present invention discloses an Ethernet Switch Ring (ESR) protection method, for introducing the pre-up state for the transit node, comprising, after the loop failure is recovered, the transit node on the loop will enter the pre-up state if not receiving the loop failure protocol message within the set time; and when the transit node is in the pre-up state and the loop is failed again, i.e., the transit node receives the loop failure protocol message in the pre-up state, the transit node opens the master and slave ports and refreshes the MAC address. Correspondingly, the present invention further discloses an ESR transit node. Since the pre-up state is introduced for the transit node and the transit node controls whether to open the recovered failed port by itself, the unsmooth flow caused by the master node which cannot notify the recovered failed port to open is avoided, and the ring network protection capability and user experience can be improved. | 06-28-2012 |
