Patent ID: 8879381

Claim:
A method for initializing a transit node in an Ethernet ring network, the method comprising the following steps: Step 1, configuring a ring node as a transit node in an Ethernet ring protection domain, wherein the transit node has two ring ports; Step 2, the transit node detecting the link state on the two ring ports: if neither of two links of the two ring ports is detected as in--fault, then the transit node recording the ring state as an initialization state, blocking at least one of the two ring ports, setting the at least one blocked port to a prerelease state, and sending a ring state query packet to a master node to query a real current ring state; Step 3, when receiving the ring state query packet, the master node sends a ring state packet recorded by the master node to a ring port thereof from which the master node receives the ring state query packet; and Step 4, the transit node checking whether the ring state packet sent by the master node has been received; and if so, the transit node unblocking the blocked port in the prerelease state.
