  • Patent number: 12212487
    Abstract: The present invention discloses a LAN system, method and unit supporting dynamic self-adaptive network configuration. Through the integration of self-adaptive dynamic routing protocol with various nodes of network, the source node broadcasts and sends a message containing destination node information, and the intermediate node searches the destination node information in its connection state sheet and returns to the source node or adds its node information into the message and sends to other intermediate nodes based on the searching results, the intermediate node will modify its routing list and open the routing transfer function. The source node and the destination node will configure their routing lists respectively with the gateway and corresponding network interfaces through which the network segment of other node is reached to establish a routing connection. The system can automatically configure the network, and greatly decrease its dependence on the central node, increasing stability and reliability.
