The network interface unit (Netw〇rk interface unit) and the terminal interface unit (Terminal Interface Unit) 13, the network nodes ίο are connected to each other by the interface unit u, connected by cables l4, i5. Dual network architecture, two recording lines 14, 15 ^ responsible for transmission in both directions 'The above interface interface controls the data transmission of each network node 10, and the terminal device (such as a computer) is connected to each node. The terminal interface unit 13 of 10, for performing packet switching, the network "area unit 12 shell controls the transmission of each packet on each network node, the transfer of 1308438 0 packets (f0rward), segmentation, reorganization, Encapsulation / decapsulation, etc. # Each network node 1 is connected to the adjacent network on the ring network via the cables 14, 15 and transmitted through one of the connection wires (for example, 'see line 14') Synchronously calibrate (synchr〇nizati〇n) messages to the next neighboring network node 10, and then pass another cable (such as cable 15) to pass back the synchronous calibration message. In the process of packet transmission, if the transmission fails, or the network route is interrupted, the above communication protocol can also provide a partial failover mechanism, and the fault recovery is a system backup. The method uses a backup system as a rescue or replaces the originally failed system, as described in the second figure for the solution of the ring topology network failure recovery, and the network architecture is as shown in the first figure. As shown in the second figure, the four network nodes are 1〇a, 1〇b, 1〇c and (10). If the network node, the signal transmitted between point i0a and network node 1〇d is wrong, such as If the cable is broken, the network is disconnected (the part marked as χ in the figure). The network node on the network will reset the connection so that the data can be transmitted smoothly, as originally passed between nodes 10a and 10d. The information needs to be transferred in the figure to frame the connection of part 20. The above technology utilizes a dual-loop network connection for fault recovery purposes, which results in a more stable network switching environment and improved fault tolerance. U.S. Patent No. 5,191,579 discloses a ring network switching control device, one of which is shown in the schematic diagram of a ring network architecture shown in the third figure, on the ring network, two 1308438 workstation A. , B, C and d, adjacent a two network systems 31 and 32, the exclusive connection, respectively forming a switching mechanism to avoid data error. . When the code line connection starts, when the system 31 is the positive station A, B, C and D are connected with the solid line part of the figure, the connection between the two lines is wrong, 誃; ^ * Workstation 3 and 0 The error message that causes the connection mechanism between the workstations B and C to switch to the second C is transmitted from the workstation B to the second station.] Second, at this time, the network is connected, and the workstation B to the workstation uses the system 31 of the system 31. When the error signal continues to be used by the Guardian, the system is used and the workstation D passes the sham station to pass the phase 1 station; 〇, switch to the system 32. The connection is the system 31 [Invention content] The standby_mechanism formed by the dual ring network architecture provides the fault tolerance capability when the ::::==. The efficiency of the phase redundant backup is improved with the network = the path includes a plurality of serials connected Network section (4) _ road 1 ^ = each network f_ mutual and adjacent, etc., when the 相 相 Γ () and the shell network address (MACaddress) neighboring network =:::=r error The problem occurs, the wrong block occurs, and the control message box U08438 is sent to the adjacent network node to get the message of the network error, so the road The node or the device will reset the network packet path = the way of the backup, the network location, the reverse direction, the path will not go through the network error and fault recovery action. The preferred embodiment of the backup topology is to establish that the physical network connected to the ring point includes first establishing a plurality of network sections, and the adjacent network sections establish a ring network, #这,二路信息By means of a control message box sent by the = node, it is known that the network packet transmission path of the adjacent Hai ring network is two or two. The network architecture of the fast node topology can be quickly performed, and each network is a network. The network address (Mac). ', two-way name (id) and the establishment of the implementation of the financial, the obstacle recovery mechanism, including the first two by the second two procedures: adjacent network node exchange::, step:: & 八闻路, when detecting the ring network, the change to the s sm lang point to the adjacent network node pass =, clear, each subsequent, make the network change information in the ring network Then, reset the ring network path to restore the connection of the ring network.匕 Passing 1308438 [Embodiment] ^The computer system of the local area network (LAN) needs to exchange some information on the network, so that each computer system can collect the network adjacent to it, the etw〇rk inf〇rmati 〇n), in general, computer systems can develop advanced broadcast packets (br°adeast) to pass the initial message to each other, = 'source and destination address, information type (message handsome two), transmission port (Port), etc. Forming a regional network after receiving each other's messages. Ben Maoming exposes a method of network message exchange, providing a simple method: the way to cross each other (-d-ki ng). For example, in the network architecture of the fourth zfn (Rlng) topology, the ring network is composed of a plurality of network nodes, each node having a line 44 - a ring network - including network nodes 41, 43, 45, each Sections ^, 45 can be a variety of devices that can be connected to the network, such as computer systems, network marriage benefits (gifts (8), etc. 'nodes 41, 43, 45 can be re-connected multiple, weekly terminal equipment 401, 402, 403, 404. The plurality of network nodes 41, 43, 45 on the ring network 40 are activated: when performing the handshake process (such as three-way handshake, Zhe Shen, andshaklng), including starting to pass μ first (ah) H_ze) j = connect (four) and then return SYN_ACK (spoken packet, === after receiving the SYN-ACK packet, then return the packet to complete = program. This handshake program can be used to check whether the signal is transmitted to and from the St. In the case of a network packet, the acknowledgment packet can be used as an error checker. The transmission is successful. If the data is transmitted after the check, the response is sent. If the response box does not receive the response box, it will be at 10:9. 1308438 Subsequent transmission (retransm (1) the second time before the handshake procedure, with the neighboring The information 'such as the network node 43 exchanges network information only with the network node and the used node, and does not exchange with other non-adjacent nodes and nodes 45. Because the network message provided by the present invention' The device of the sixth carries the message to the neighboring node for network information exchange. The different two= method is only related to all the devices on the network of the node, so it can be simplified a lot: = The technology needs to be broadcasted to the embodiment to the Ethernet network ( Eth n ^ The step of heart transfer. The above exchanged information includes at least the network; Internet (Internet Protocol address) (Internet address address (cafe-add coffee), each network ==), physical network, etc. That is, the identification name (ID) of the account is clearly used because of the use of simplified inter-node handshake, so that when there is a problem in the following, ., the road can also quickly and effectively operate. The recovered network sections and the information exchange between the network nodes after the message exchange, wherein the start and end flags of the -, delimiter (delimiter) are at the beginning and end. Between bits, a data frame except for the wish The data to be sent is usually included, including the address area, the bit value used for control and inspection, etc. This volume is more advantageous when the network type or topology (top〇i〇gy) changes. A plurality of control message boxes (Cc) ntrQl Fra嶋) are used as status communication before the data frame transfer between nodes on the network, and the content is as shown in the fifth embodiment, including the start bit (start 5) 〇ι,

At this time, neighboring data The network node that transmits the location where the error occurred will send the above control message box to its neighboring node or network, as shown in the sixth figure.
