[0001] The present invention relates to the technical field of data transmission, and in particular to a low-latency optimized network access method and system for industrial complex networks. Background Art

[0002] With the rapid development of computer technology and communication technology, more and more communication networks have the following characteristics: in terms of composition, a single subnet is a simple network such as a transmission network, a mobile network, etc.; in terms of structure, multiple structures of networks in different periods coexist, and the centralized network gradually develops to a distributed network; in terms of application, it develops from a single, simple function to a diverse, multi-layer and polymorphic network; in terms of service, it pays more and more attention to performance, quality and security; in terms of technology, multiple technologies coexist and merge with each other. Since these communication networks are different from the simple networks with simple composition, clear structure and single function in the past, nor are they equivalent to the composite superposition of simple networks, but present new characteristics in terms of network composition, network model, network technology and network management, they cannot be directly analyzed by traditional theories.

In order to solve the problems of slow connection establishment in TCP protocol transmission, frequent connection interruptions caused by network switching, difficulty in re-establishing connection after network disconnection, and data transmission in weak network environments being limited by congestion, packet loss detection and retransmission mechanisms.

[0071] In this example, a network edge node refers to a node located at the edge of a network and has the functions of processing, storing, forwarding, and filtering data;

[0072] In this example, the optimized network can transmit the data generated by the network-connected device to the corresponding data receiving device.

[0073] The working principle and beneficial effects of the above technical solution: In order to ensure the quality of data transmission of different devices in a complex network, the transmission work of each network-connected device is first supervised to determine the data transmission quality of different network-connected devices, and then the data generated in the target network-connected device with low transmission quality is transmitted to the network edge node for storage, and then the network is replaced and optimized for the target network-connected device, thereby ensuring the quality and compatibility of the network after replacement, and finally the corresponding target transmission data is transmitted. In this way, the network can be modified and optimized for devices with slow data transmission, and the network edge node with the million-level message processing capability is used to temporarily store data, effectively avoiding data loss and interruption, and providing a complete and reliable data transmission solution for the industrial field.

[0074] Example 2

In this way, not only can the impact between different network access devices be determined, thereby avoiding network access for different network access devices, but also the actual supply demand of each network access device can be analyzed according to the efficiency impact characteristics, so as to determine the data transmission quality of the network access device in combination with the efficiency difference of the network access device. In this way, the network access devices can be supervised in an all-round and long-term manner to obtain complete and effective data transmission quality.

[0087] Step 22: Locate the target network access device whose data transmission quality is lower than the corresponding standard transmission quality, find the target access network corresponding to the target network access device, deduce a number of network edge nodes included in the target access network according to the topological structure of the target access network, and obtain the physical identification corresponding to each of the network edge nodes respectively;

[0088] Step 23: Retrieve the target data corresponding to the target network access device, perform status analysis on the target data, determine the transmitted segments and the untransmitted segments in the target data, perform enhancement processing on the untransmitted segments, and obtain enhanced target data corresponding to each of the target network access devices;

[0089] Step 24: Determine a target network edge node with a storage function according to the physical identifier, add a source tag to the enhanced target data according to the target network access device, and transmit it to the target network edge node for storage.

[0090] In this example, the preset sliding window mechanism represents a method for performing flow control;

[0096] In this example, one enhanced target data corresponds to one source tag, and the source tag corresponds to the target network access device.

[0097] The working principle and beneficial effects of the above technical solution are as follows: a preset sliding window mechanism is used to control the data transmission requirements of network access devices, and the minimum transmission requirements of network access devices are determined, thereby generating a standard transmission quality for network access devices. Target network access devices with low transmission quality can be screened according to the standard transmission quality. At the same time, the network edge nodes in the target access network are derived according to the topological structure of the target access network corresponding to the target network access device, and then the target network edge nodes with storage function are determined according to the physical identification of the network edge nodes. Then, the target data in the target network access device is partially enhanced to ensure the integrity of the untransmitted fragments. Finally, the enhanced data is transmitted to the target network edge node for storage. In this way, the data can be temporarily stored to avoid data loss.

[0103] Step 34: Generate a plurality of transmission rules according to the target standard transmission quality corresponding to the target network access device, use each of the transmission rules to optimize the compatibility information of the replacement network, and use the target compliance information corresponding to the replacement network to determine the non-compliant data receiving devices of the replacement network, optimize the protocol information of the updated network according to the data receiving rule corresponding to each of the non-compliant data receiving devices, and generate an optimized network for the target network access device.

[0104] In this example, the available network refers to the network that the target network-accessing device can access.

[0105] The working principle and beneficial effects of the above technical solution are as follows: according to the transmission information of the target network-access device, the multiple data receiving devices corresponding to the data transmission are determined; by constructing a transmission structure distribution map of the target network-access device and combining the network access information of each data receiving device, a network access information distribution map is established; further, key information is extracted from the transmission information of the target network-access device; the transmission purpose of the target network-access device is determined according to the key information, so that the transmission purpose can be used to find available networks; a network access information distribution map is constructed by mapping means; the network is selected and replaced according to the matching information between different available networks and the network access information distribution; finally, the target standard transmission quality of the target network-access device and the non-matching data receiving device are used to optimize the updated network, and the optimized network of the target network-access device is obtained. In this way, not only the network of the network-access device can be replaced, but also the replaced network is optimized, thereby improving the efficiency of subsequent data.
