A kind of method flow that recovers the looped network business of the present embodiment comprises as shown in Figure 2:
Step 101: after ethernet link broke down, the transmission node at faulty link two ends sent link failure message to Control Node 20, can comprise the MAC of transmission node and the ID of non-working port in this message.
As shown in Figure 3, between transmission node 12 and the transmission node 13, be that link between port id=6 and port id=7 breaks down, this moment, transmission node 12 and transmission node 13 can block separately non-working port 6 and port 7 respectively, and send link failure message to Control Node 20 respectively, the MAC and the non-working port ID=6 that can comprise transmission node 12 in the message that transmission node 12 sends can comprise the MAC and the non-working port ID=7 of transmission node 13 in the message that transmission node 13 sends.Certainly the failure message ID that yet can include only non-working port does not comprise the MAC of transmission node, and the MAC that comprises transmission node is that port also can be identified when guaranteeing that port id is identical.
Step 102: the failure message that the transmission node that Control Node 20 receives the faulty link two ends sends over.
Failure message comprises that the failure message sending node is positioned at the identification information of faulty link one end port, and Control Node 20 can be selected the standby port that conduct is new according to ID value and the MAC in two failure messages from two ports.The ID value 6 in the failure message that this moment, Control Node 20 can send over according to transmission node 12 and the MAC of transmission node 12, and the ID value 7 in the failure message that sends over of transmission node 13 and the MAC of transmission node 13, select non-working port 6 will become new standby port, can certainly select non-working port 7 will become new standby port, present embodiment will not become new standby port to which non-working port and limit.
