Description

Technical Field

[0001] The present invention relates to the field of data transmission technology, 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 and communications technologies, an increasing number of communication networks have developed the following characteristics: Their composition manifests as simple individual subnets, such as transmission networks and mobile networks; their structure manifests as the coexistence of networks of various structures from different eras, gradually evolving from centralized to distributed; their applications manifest as a shift from single, simple functions to diverse, multi-layered, and polymorphic services; their services increasingly prioritize performance, quality, and security; and their technologies manifest as the coexistence and integration of multiple technologies. These communication networks differ from the simple structures, clear structures, and single functions of previous generations, nor are they simply composite superpositions of simple networks. Instead, they exhibit new characteristics in network composition, network models, network technologies, and network management, defying straightforward analysis using traditional theoretical approaches. These networks are collectively referred to as complex networks.

[0003] Complex networks are now gradually entering the industrial field. However, the low-latency and highly reliable communication transmission technology for complex industrial network environments currently relies mainly on the TCP protocol for the transmission of message data. In industrial Internet of Things application scenarios, various complex network environments are encountered. 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 connections 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 the network that has the functions of processing, storing, forwarding, and filtering data;

[0072] In this example, the optimized network can transmit data generated by networked devices to corresponding data receiving devices.

[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 ability to process millions of messages 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.

[0075] Based on Example 1, the low-latency optimized network access method for an industrial complex network, step 1, includes:

[0076] Step 11: respectively obtain the data transmission type and data transmission frequency corresponding to each of the networked devices, determine the data transmission requirements corresponding to each of the networked devices, and respectively obtain the TCP protocol corresponding to each of the networked devices;

[0080] In this example, the load information represents the load generated by all access devices accessing the network;

[0081] In this example, the efficiency impact characteristics differ between different devices;

[0082] In this example, the data transmission offer and demand represents the maximum transmission that the access network can provide.

[0083] The working principle and beneficial effects of the above technical solution: In order to supervise the transmission work of the network-accessing equipment, the data transmission requirements of the network-accessing equipment are first constructed according to the data transmission type and data transmission frequency of the network-accessing equipment, and then the data transmission supply and demand of the access network are determined according to the TCP protocol, so as to perform real-time supervision of the access network to determine the corresponding real-time supervision results at each moment, as well as the load information of the access network, so as to determine the efficiency impact characteristics between different network-accessing equipment. In this way, not only the impact between different network-accessing equipment can be determined, thereby avoiding the access of different network-accessing equipment, but also the actual supply demand of each network-accessing equipment can be analyzed according to the efficiency impact characteristics, so as to determine the data transmission quality of the network-accessing equipment in combination with the efficiency difference of the network-accessing equipment. In this way, the network-accessing equipment can be supervised in an all-round and long-term manner to obtain complete and effective data transmission quality.

[0084] Example 3

[0085] Based on Example 1, the low-latency optimized network access method for an industrial complex network, step 2, includes:

[0086] Step 21: Obtain the data transmission requirements corresponding to each of the networked devices, perform transmission flow control on the data transmission requirements using a preset sliding window mechanism, obtain the minimum transmission requirement of each of the networked devices, and determine the standard transmission quality of the networked devices based on the minimum transmission requirements;

[0087] Step 22: Locate a target network-accessing device whose data transmission quality is lower than the corresponding standard transmission quality, search for a target access network corresponding to the target network-accessing device, deduce a number of network edge nodes included in the target access network based on the topology of the target access network, and obtain a physical identifier corresponding to each of the network edge nodes;

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

[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 the data to the target network edge node for storage.

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

[0091] In this example, the minimum transmission requirement indicates the minimum requirement for network access devices to transmit data;

[0092] In this example, one network access device corresponds to one standard transmission quality;

[0093] In this example, one target access network corresponds to one topology;

[0095] In this example, the purpose of strengthening the untransmitted segments is to: 1. avoid the loss of untransmitted segments, 2. distinguish between transmitted segments and untransmitted segments;

[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 the network access device, and the minimum transmission requirements of the network access device are determined, thereby generating a standard transmission quality for the network access device. According to the standard transmission quality, the target network access device with low transmission quality can be screened, and at the same time, the network edge node in the target access network is derived according to the topological structure of the target access network corresponding to the target network access device, and then the target network edge node with storage function is determined according to the physical identification of the network edge node, and then the target data in the target network access device is partially enhanced to ensure the integrity of the untransmitted fragments, and finally the enhanced data is transmitted to the target network edge node for storage, so that the data can be temporarily stored to avoid data loss.

[0101] Step 32: Extract key information from the transmission information corresponding to each target network device, construct the transmission purpose corresponding to the target network device by combining semantic analysis technology, and search for multiple available networks within the effective connection range of the target network device based on the transmission purpose;

[0102] Step 33: Map each of the available networks to the network access information distribution map, obtain the matching information between each of the available networks and the network access information distribution map, construct the matching information, and extract the target available network with the highest matching degree, which is considered as the replacement network;

[0103] Step 34: Generate several transmission rules based on 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 compatibility information corresponding to the replacement network to determine the non-compliant data receiving devices of the replacement network. According to the data receiving rule corresponding to each of the non-compliant data receiving devices, optimize the protocol information of the updated network to generate an optimized network for the target network access device.

[0104] In this example, available networks refer to networks 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 corresponding multiple data receiving devices when it transmits data are determined, and the network access information distribution map is established by constructing a transmission structure distribution map of the target network access device and combining it with the network access information of each data receiving device. The key information of the transmission information of the target network access device is further extracted, and 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, and the network access information distribution map is constructed by mapping means. The replacement network is screened according to the matching information between different available networks and the network access information distribution, and 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.
