Abstract: A network configuration system based on location of the device transmits a transient network configuration via a server to a node to set the network configuration thereof. Link layer discovery protocol (LLDP) information produced at the node is used to search for a default network management table in order to obtain the actual network configuration. The network configuration of the node is then updated according to the actual network configuration. The corresponding configuration method is also proposed. The mechanism helps improve the convenience in setting the network configuration.

Abstract: The present invention relates to a method for conducting redundancy checks in a chain network, wherein the two ends of the chain network are equipped with a first switch and a second switch respectively, and a port of the first or second switch used for communicating with an external network is set to be blocked, so that when an link failure happens to any switch of the chain network, the two switches close to the link failure port sends control packets to the first and second switches respectively to forward the port that is originally blocking, thus making the network to return to normal state quickly. Besides, as the first and second switches are used to connect other chain networks, external network devices or external redundant network architectures, it allows more network nodes to be included in single network architecture and provides flexibility and compatibility in use by including different redundancy mechanisms.

Abstract: A method for checking a ring network redundancy includes a first exchanger and a second exchanger. When the first exchanger is set as a master, the plurality of second exchangers serve as the ring members; the first exchanger has a connection port, which is set as blocking, and the rest of connection ports are set as forwarding. The plurality of second exchangers regularly detects the plurality of connection ports for any outstanding status occurred in the connection status. When an outstanding status occurred, the CF5 is transmitted to the first exchanger and the first exchanger converts the connection port into the forwarding status, and the CF4 is transmitted to the plurality of second exchangers in order to renew the Mac address table. The method of sending out CF through a plurality of ring members can reduce the risk of losing the CF due to overloading network or having too much single network equipments, and thereby increase the reliability of the ring network during the redundancy checking.
