ETHERNET RING NETWORK SYSTEM, TRANSMISSION NODE OF ETHERNET RING NETWORK AND INTIALIZATION METHOD THEREOF

摘要

The present invention is an Ethernet ring network system, the sending node and provides the initialization method to, the method as in Step 1 to generate an Ethernet ring network protection domain sending node to node on the ring, the transmission node to detect the link status of ports on the two rings is a fault in the link transmission node of the two ports on the ring Once you have detected that the record has not occurred in the ring network state initialization state and set at least one port on at least one ring and a closure closing the port on the ring in the pre-release state, and transmits a status inquiry message to the main node ring network and the step 2 to the step of transmitting a ring network status messages are recorded by the main node on the ring port receives the message ring network status inquiry after receiving the ring network status inquiry message from the main node 3 and the ring network state to the initial situation After you have determined that the sending node and receiving entity receives the ring network a status message transmitted from the main node to open the occluded port of a pre-release state and a step 4 for implementing the initialization of the sending node.
