Embodiment 1

[0057] A local area network system that supports dynamic adaptive network configuration, which is based on a conventional local domain network topology structure, and any network node in the system is a local area network device that supports dynamic adaptive network configurations. The various network nodes of the system are in a physical connection state, such as a wireless network through the network cable, the optical cable or the same frequency band. According to the prior art, each physical interface connection of the node device simulates a network interface, and the network interface is assigned the corresponding IP address, and each network interface allocates a separate port number for listening to the command request. Each physical interface is based on existing technologies to complete the simulation of the NIC. For example, USB will be based on RNDIS technology. Bluetooth is based on BT PAN technology, WLAN and traditional Ethernet network card belong to standard netw...

Embodiment 2

[0116] The method of this embodiment is different from that of the first embodiment, and there is two or more forwarding nodes between the source node A and the destination node C. The device serial number of the destination node C is known, and the connection of 34762Ab641c347e1, each node connection Method Figure 7 Among them, the source node A, the intermediate node D, E, the destination node C, the leaves node B and E are all PCs that support the DRP adaptive dynamic routing protocol, and the device serial number of the source node A is 64672Ab641C647EC, the device sequence of the intermediate node D. No. 65322CA531CA46EC, the device serial number of the intermediate node E is 56452ba531ca4625;

[0117] The source node A and the intermediate node D are connected by Ethernet cable. The IP of the Ethernet port of the source node A is 192.168.40.2, the port number 5555, the IP of the Ethernet port connected to the destination node D is 192.168.40.1, Port number 5555;

Embodiment 3

[0162] The method of the present embodiment is different from the first embodiment in that the present embodiment implements the source node to forward the transmitted file request, the intermediate node, and after finding the destination node containing the target file, each node configures its own routing, establishing The source node to the route of the destination node or the destination node containing the target file, such as figure 2 As shown, the source node c requests a file, the file identity of the known file, needs to find the destination node A with the target file, and establish a route.

[0163] In Example 1 DRP service daemon in each node, in addition to creating a state machine unit, an interface connection monitoring unit, an resource management unit, a resource management unit creates and maintains a list of shared resource, and saves the node device. The specific information of files that can be shared through the network, including the unique file identity, fi...

Abstract

The invention discloses a local area network system, a method and a device supporting dynamic self-adaptive network configuration, which are characterized in that a self-adaptive dynamic routing protocol is integrated through each network node, a source node broadcasts and sends a message containing destination node information, an intermediate node checks a connection state table of the intermediate node and looks up the destination node information; it is returned to the source node according to a search result or adding self node information into a message and continuing to forward the message to other intermediate nodes, and after a destination node is searched, a self routing table is modified by the intermediate nodes and a routing forwarding function is opened by the intermediate nodes; and the source node and the destination node respectively configure the gateways and the corresponding network interfaces which reach the opposite network segment into own routing tables so as to establish routing connection. The system automatically configures the network according to the actual data transmission requirement and the physical connection state of the network equipment, no obvious central node exists, the system is a decentralized system, the dependence of the system on the central node is greatly reduced, and the stability and reliability of the system are improved.

Description

Technical field [0001] The present invention relates to the field of network communication, and in particular, to a local area network system, method, and apparatus that supports dynamic adaptive network configuration. Background technique [0002] At present, the mainstream local network network network is basically constructed based on a central node, such as one or several routers in the network, other devices connected to the router, communication between the various devices, forwarded by router nodes. When a local area network needs to communicate with another LAN, it is necessary to forward the central node (router, gateway). For network engineers, network engineers need to manually configure routing rules, address translation rules such as address conversion rules such as the central node. Configuration information. Mainstream local network network network mode is mostly similar to figure 1 Topology. As can be seen from the figure, the mainstream local area network network...
