Abstract
The present invention provides an Ethernet ring system, transit node of Ethernet ring system, and initialization method thereof, wherein the method includes the following steps: step 1, generating a transit node of Ethernet ring protection domain by means of ring nodes; step 2, detecting the link state of two ring ports by means of the transit node: if neither of the two ring ports is detected as in-fault, then recording ring the link state as initialization state, blocking at least one of the ring ports, setting the at least one blocked port in prerelease state, and sending a ring state query packet to a master node, by means of the transit node; step 3, when the ring state query packet is received, sending a ring state packet recorded by the master node to the ring port that receives the ring state query packet, by means of the master node; and step 4, checking whether the ring state packet sent by the master node have been received by the transit node of which the ring state is the initialization state; if so, unblocking the blocked port in the prerelease state, to realize initialization of the transit node.
