Patent ID: 8675477

Claim:
An address refreshing method of an Ethernet ring network, comprising: when a current node state of each node in the Ethernet ring network is a protection state, if a failure of a first link in the Ethernet ring network disappears, transmitting a No Request (NR) protocol message indicating that the link failure disappears through node(s) connected with the first link; a node in the Ethernet ring network which receives the NR protocol message switching the node state of the node into a pending state; and when the current node state of each node in the Ethernet ring network is the pending state, if a link failure appears in the Ethernet ring network, transmitting a link failure notification (SF) protocol message through node(s) connected with the failed link; a node in the Ethernet ring network which receives the SF protocol message switching the node state of the node into the protection state, and refreshing an address forwarding table according to address refreshing information carried in the SF protocol message; and after receiving the NR protocol message indicating that the link failure disappears, a control node of the Ethernet ring network starting a wait-to-recover (WTR) timer, and transmitting, after the WTR timer expires, an NR protocol message indicating that a ring protection link has blocked the forwarding of a data message.
