Many existing systems still rely on static rules and experience, lack intelligent decision support based on big data analysis, and cannot achieve adaptive adjustment of complex network states. In the case of uneven traffic, the existing load balancing strategy may cause some switches to be overloaded while others are idle, resulting in low resource utilization efficiency and further affecting user data transmission experience and network operation stability.

[0044] The embodiments of the present application have at least the following beneficial effects:

[0045] In the peak period of data transmission, in order to ensure that the data with high priority can be quickly transmitted, the data with high priority needs to obtain more network resources when transmitting in the network channel. More network resources can effectively avoid the delay transmission of important data caused by network resource shortage. Therefore, the present application first determines the network resource requirement degree of the transmission data in the network channel by analyzing the transmission rate and the size of the data packet and other characteristics of the traffic data in different network channels. The transmission data with higher network resource requirement degree may need more network resources in the actual transmission process to ensure the accurate transmission of critical data. In the environment of the peak period of data transmission, the data with higher network resource requirement degree usually contains more important information or data packets with higher real-time requirements. Such data needs higher resource requirement degree in the transmission process, but congestion or data loss may occur in the data transmission process. In order to avoid data loss, the loss probability of the network channel is determined by combining the network resource requirement degree and the network congestion degree. The loss probability is determined by combining the network congestion degree because if the data packets are congested and blocked in the data transmission process in the network channel, the data with higher network resource requirement is more likely to lose data. Then, the network bandwidth adjustment value is determined by combining the loss probability and the sending interval of the data packet, so as to realize the flexible allocation of network resources according to real-time traffic demand, dynamically adjust the bandwidth to ensure the bandwidth required by high-demand data, and avoid unnecessary resource waste. Dynamic adjustment of bandwidth between different network nodes helps to realize load balancing, reduce the risk of overload of individual nodes, and improve the overall network performance.

[0056] The embodiments of the present application are described below with reference to the accompanying drawings. Those skilled in the art can know that with the development of technology and the appearance of new scenarios, the technical solutions provided by the embodiments of the present application are also applicable to similar technical problems.

[0057] The embodiment of the application provides a 5G communication network switch control method, system and specific implementation method of an electronic device, and the method is suitable for the field of network communication, and the 5G communication network switch is used for connecting different devices, such as robots, sensors and actuators, to realize an efficient production process; through the 5G communication network switch, each device can quickly transmit data, realizes interconnection and intercommunication, and supports industrial Internet of Things application; the intelligent control method can flexibly respond to changes in production demand, and improves production efficiency and resource utilization.

[0058] The specific scheme of the 5G communication network switch control method, system and electronic device provided by the application will be described in detail below with reference to the drawings.

[0059] Please refer to Figure 1 , which shows the step flowchart of the 5G communication network switch control method provided by the embodiment of the application, and the method comprises the following steps:

[0060] In step S100, monitoring data in the 5G communication network switch is acquired, and the monitoring data comprises flow data, data packet information, network delay data and bandwidth utilization.

[0061] In the intelligent manufacturing and industrial automation environment, the 5G communication network switch needs to collect various data in the control process to ensure efficient operation and real-time response of the system, and the main data types collected include network state data, device state data, production line state data and environment monitoring data. More specifically, the monitoring data in the 5G communication network switch in the embodiment of the application comprises flow data, data packet information, network delay data, bandwidth utilization, the length of the monitoring time period, the actual bandwidth of the network and the total number of data bytes transmitted in the monitoring time period; wherein the data packet information comprises the number of bytes contained in the data packet, the priority of the data packet and the flow frequency of the data packet.

[0062] Sensors and monitoring devices are deployed on the 5G communication network switch machine-related equipment, and the data collected by the sensors should cover all the above-mentioned data types and can collect data in real time.

[0063] The network interface is configured so that the switch can communicate data with the sensors and monitoring devices; the data collection frequency is set according to the requirements of different data types, and the format of the collected data is determined to ensure the consistency and readability of the data; the data collection program is started, and the sensors start collecting data; in the central control system, the collected data is further analyzed, and the running state of the communication network switch is adjusted according to the analysis result.

[0064] According to the flow sensor, real-time flow data in the 5G communication network switch in the monitoring time period is obtained. In the embodiment of the application, the monitoring time period can be set to 10 minutes. The unit of the flow data is Mbps.

[0065] Since the 5G communication network switch is not only one network communication channel, according to different technical architectures and application scenarios, the 5G communication network switch realizes efficient data transmission and network management through multi-channel design. It should be noted that in the subsequent steps, the network communication channel is referred to as the network channel. For each network channel, corresponding monitoring data can be obtained.

[0066] In step S200, the network resource demand degree of the to-be-transmitted data in the single network channel is obtained according to the transmission of the flow data in the entire 5G communication network switch and the data packet information.

[0067] The analysis of the data flow change trend in the 5G communication network switch can be used to monitor the performance of the network environment in real time, and the data flow change trend can help to identify the bottlenecks and problem areas in the 5G communication network switch communication network, thereby providing a basis for optimizing network resource allocation.

[0068] First, the data transmission rate of the single network channel is determined. The greater the data transmission rate, the faster the corresponding data transmission speed. When the data transmission rate is faster and the flow data transmitted by the network channel is more, it can better represent that the network channel is currently in a flow transmission peak stage, and the flow overload of the network is stronger.

[0069] In the embodiment of the application, the data transmission rate of the single network channel is obtained by taking the ratio of the total number of data bytes transmitted in the monitoring time period to the length of the monitoring time period as the data transmission rate of the single network channel.

[0070] In some embodiments, according to the transmission of the flow data in the entire 5G communication network switch and the data packet information, the network resource demand degree of the to-be-transmitted data in the single network channel is obtained, that is, the above step S200 can be realized by Figure 2

[0071] In step S210, the transmission peak probability of the single network channel is determined according to the transmission of the flow data in the entire 5G communication network switch.

[0072] First, for the single network channel, the flow overload of the single network channel is determined according to the data transmission rate and the flow data.

[0073] ​In some embodiments, the average value of the traffic data of the single network channel in the monitoring time period is calculated as a traffic overall value; the traffic overall value and the data transmission rate are combined to obtain the traffic overload of the single network channel; wherein the traffic overall value and the data transmission rate are positively correlated with the traffic overload. More specifically, the traffic overload is the product value of the traffic overall value and the data transmission rate.

[0074] In the monitoring time period, the amplitude change of the network traffic data in the single communication channel and the data transmission rate per unit time can represent whether the network is overloaded, and the traffic overload of the corresponding communication channel can reflect that the network switch may be in a peak period.

[0075] Further, the traffic overload of the single network channel and the entire 5G communication network switch communication network is compared to obtain the transmission peak probability of the single network channel.

[0076] The average value of the traffic overload of all network channels in the entire 5G communication network switch is obtained as a traffic average overload; any network channel is taken as an analyzed network channel, and the first probability of the analyzed network channel is determined according to the difference between the traffic overload of the analyzed network channel and the traffic average overload.

[0077] The greater the first probability is, the greater the overall difference between the traffic complexity of the analyzed network channel and other network channels in the 5G communication network switch is, and the probability of the analyzed network channel for assisting the data transmission peak period is greater.

[0078] In some embodiments, the first probability is the absolute value of the difference between the traffic overload of the analyzed network channel and the traffic average overload.

[0079] The traffic overload of the analyzed network channel and other network channels in the entire 5G communication network switch is compared to determine the second probability of the analyzed network channel.

[0080] The greater the second probability is, the higher the traffic complexity of the analyzed network channel is than other network channels.

[0081] In some embodiments, the second probability is the average value of the ratio of the traffic overload of the analyzed network channel to other network channels.

[0082] The first probability and the second probability are combined to obtain the transmission peak probability of the analyzed network channel. The first probability and the second probability are positively correlated with the transmission peak probability.

[0083] In some embodiments, the product value of the first probability and the second probability is taken as the transmission peak probability.

[0084] Step S220, according to the data packet information, determine the data transmission priority of the single network channel.

[0085] In peak hours, network bandwidth becomes a scarce asset. If the data priority is not distinguished in the process of data transmission, all traffic will compete equally, and critical data will be delayed or even lost due to resource contention. Therefore, data transmission without distinguishing data priority is not conducive to the efficient operation of the communication network switch.

[0086] In the communication network, analyzing the data flow to determine whether the single network channel is in the peak period is an important step, which provides important context information for the control of the network switch. In high-load conditions, reasonable priority scheduling can improve the utilization efficiency of network resources. By transmitting data packets with higher importance first, the limited bandwidth resources can be used more effectively, ensuring the improvement of overall network performance.

[0087] The 5G communication network switch can count the traffic generation frequency. Different data packets have certain traffic frequencies during transmission. The traffic frequencies of different data packets are obtained, and the number of bytes contained in the data packets is recorded. It should be noted that the traffic frequency of the data packet is data packet / second.

[0088] In the VLAN label of the data frame, the "User Priority" field explicitly identifies the priority level of 0-7. The higher the value of the priority level, the higher the priority. The priority of a single data packet in the current network channel is obtained.

[0089] Generally, data packets with high transmission priority have the characteristics of high frequency and low packet. Therefore, according to the data packet information and the priority of the data packet itself, the data transmission priority of the single network channel is determined.

[0090] For a single network channel, the average value of the traffic frequencies of all data packets in the monitoring period is calculated as the overall frequency value of the data packets.

[0091] The average value of the number of bytes of all data packets in the monitoring period is calculated as the overall byte value of the data packets.

[0092] The average value of the priority of all data packets in the monitoring period is calculated as the overall priority value of the data packets.

[0093] According to the overall frequency value of the data packets, the overall byte value of the data packets, and the overall priority value of the data packets, the data transmission priority of the single network channel is obtained. The overall frequency value of the data packets, the overall priority value of the data packets, and the data transmission priority are positively correlated, and the overall byte value of the data packets and the data transmission priority are positively correlated.

[0094] In some embodiments, the transmission priority q of the rth network channel in the monitoring time period r The calculation formula is: Wherein, is the overall packet frequency value of the rth network channel in the monitoring time period; is the overall packet byte value of the rth network channel in the monitoring time period; is the overall priority value of the rth network channel in the monitoring time period.

[0095] The greater the transmission priority, the higher the data transmission priority in the current network channel, and the data with higher transmission priority usually points to some critical service data, such as monitoring, device status in industrial environment, etc.

[0096] Step S230, in combination with the transmission peak probability and the data transmission priority, determine the network resource demand degree of the data to be transmitted in the single network channel.

[0097] In the peak period of data transmission, in order to ensure that the data with high priority can be quickly transmitted, it is necessary for such data to obtain more network resources when transmitting in the communication channel. More network resources can effectively avoid the delay transmission of important data caused by network resource shortage. Therefore, in combination with the transmission peak probability and the data transmission priority, the network resource demand degree of the network channel is determined. The greater the transmission peak probability and the data transmission priority, the higher the network resource demand degree of the data to be transmitted in the network channel, that is, the transmission data with higher network resource demand degree may need more network resources in the actual transmission process to ensure the accurate transmission of critical data.

[0098] In the embodiment of the application, the product value of the transmission peak probability and the data transmission priority is taken as the network resource demand degree of the data to be transmitted in the single network channel.

[0099] Step S300, according to the fluctuation level of network delay data and bandwidth utilization, determine the network congestion degree of data transmission in the single network channel; in combination with the network resource demand degree and the network congestion degree, determine the loss probability of data loss in the single network channel.

[0100] In the single network channel of the 5G communication network switch, in the environment of the data transmission peak period, the data with high network resource demand degree usually contains important information or real-time requirement high data packet. Such data needs high resource demand degree in the transmission process, but it does not exclude the congestion or data loss in the data transmission process.

[0101] After the network resource demand degree analysis of the data transmission process in a single network channel is completed, this step lays a foundation for understanding the resource occupation of data in the network. However, to comprehensively evaluate the network performance and user experience, it is not enough to simply consider the resource demand of data. In the actual data transmission process, the data loss situation is also extremely important.

[0102] Obtain the broadband utilization of the data in the current network channel in the monitoring time period, which is usually presented in the form of percentage.

[0103] Using tools such as Wireshark, MTR, Traceroute, etc., real-time monitoring of network delay is performed, and delay data is recorded.

[0104] Calculate the variance of the network delay data of a single network channel in the monitoring time period as the delay fluctuation of the single network channel. The delay fluctuation is used to evaluate the network jitter in the data transmission process, and unstable jitter often leads to data packet loss.

[0105] According to the change of the bandwidth utilization of a single network channel at different times in the monitoring time period, the bandwidth occupation trend of the single network channel is obtained. Specifically, for a single network channel, the bandwidth utilization at each time position in the current monitoring time period is fitted to obtain the bandwidth utilization curve of the data transmission process in the single network channel in the current monitoring time period. The average value of the slope values of different times in the monitoring time period is calculated as the bandwidth occupation trend of the single network channel; wherein the slope values of different times on the bandwidth utilization curve reflect the change of the bandwidth utilization at different times in the monitoring time period.

[0106] The greater the bandwidth occupation trend, the higher the frequency of bandwidth resource occupation in the data transmission process of the current network channel, and the bandwidth occupation trend is continuously increasing; the higher the bandwidth occupation trend, the more likely to cause network congestion, thereby increasing the risk of data loss. The ideal bandwidth utilization should generally be kept within a reasonable range, such as 70%-80%, to ensure the normal operation of the network.

[0107] Combined with the delay fluctuation and the bandwidth occupation trend, the network congestion degree of the data transmission in a single network channel is determined. The delay fluctuation and the bandwidth occupation trend are positively correlated with the network congestion degree.

[0108] In the embodiment of the application, the product value of the delay fluctuation and the bandwidth occupation trend is taken as the network congestion degree of the data transmission in a single network channel.

[0109] When the delay fluctuation is greater, the bandwidth occupation trend is greater, and the probability of blocking in the data transmission process in the current network channel is greater.

[0110] Therefore, the loss probability of data loss of a single network channel is determined in combination with the network resource requirement degree and the network congestion degree.

[0111] In the embodiment of the application, the product value of the network resource requirement degree and the network congestion degree is taken as the loss probability of data loss of a single network channel.

[0112] Step S400, according to the loss probability and the sending interval of the data packet, a network bandwidth adjustment value of a single network channel is determined, and based on the network bandwidth adjustment value, the network actual bandwidth of each network channel in the 5G communication network switch is adjusted to obtain a network corrected bandwidth of each network channel.

[0113] The network resources can be flexibly allocated according to real-time traffic demand, the bandwidth is dynamically adjusted to ensure the bandwidth required by high-demand data, while unnecessary resource waste is avoided, and the bandwidth is dynamically adjusted between different network nodes, which helps to realize load balancing, reduce the overload risk of individual nodes, and improve the overall network performance.

[0114] The sending time of a single data packet in a single network channel of the 5G communication network switch is recorded, and the sending time interval between adjacent two data packets is obtained.

[0115] In the data transmission process, if the sending time interval of the data packet is short or a large number of data packets are transmitted at the same time, the bandwidth resources in the current network channel are obviously not enough, and then the demand for the bandwidth resources of the current network channel can be taken as data support for dynamically adjusting the network bandwidth.

[0116] The sending time interval value of the data packet of a single network channel in a monitoring time period is negatively mapped to obtain an interval compact value of the single network channel.

[0117] The interval compact value and the loss probability are combined to obtain a network bandwidth adjustment value of a single network channel, wherein the interval compact value and the loss probability are both normalized values. The loss probability is positively correlated with the network bandwidth adjustment value, and the interval compact value is negatively correlated with the network bandwidth adjustment value. Because the loss probability represents the probability of data loss of the network channel, the greater the probability of data loss, the greater the value of the loss probability, and the greater the need for network bandwidth adjustment.

[0118] In the embodiment of the application, the network bandwidth adjustment value x r of the rth network channel is calculated according to the following formula: Wherein, S r is the loss probability of the rth network channel; is the average value of the sending time interval of the data packet of the rth network channel in the monitoring time period; is the interval compact value of the rth network channel; e is a natural constant; th is a hyperbolic tangent function, which is used to normalize the loss probability; wherein, is used to realize the negative correlation normalization mapping of .

[0119] The greater the network bandwidth adjustment value, the more the current network bandwidth resource is insufficient to support a large amount of data transmission in the data transmission process of the current network channel, and a large amount of data may cause congestion and loss of critical data in the transmission process, that is, the higher the network bandwidth adjustment demand in the current network channel.

[0120] Finally, based on the network bandwidth adjustment value, the network actual bandwidth of each network channel in the 5G communication network switch is adjusted to obtain the network correction bandwidth of each network channel. Specifically, the network bandwidth adjustment value is used as an adjustment coefficient, and the network actual bandwidth of the corresponding network channel is multiplied to obtain the network correction bandwidth of the corresponding network channel. It should be noted that each network channel has its own corresponding network correction bandwidth.

[0121] The control command format is determined, and RESTAPI or SNMP is usually used for switch configuration. For example, for SNMP, the following MIB objects can be used for bandwidth adjustment: ifSpeed: set the bandwidth of the interface; ifHighSpeed: set for high-bandwidth interfaces; and then generate control commands such as increasing bandwidth or decreasing bandwidth.

[0122] The generated control command is sent to the target switch through the network management system (NMS) or the SDN controller. Encryption protocols such as SSL / TLS are used to protect the safety of the control signal.

[0123] After the switch receives the control signal, the command is automatically executed, the port configuration is updated, and the bandwidth setting is adjusted; after execution, the bandwidth usage is monitored in real time through the flow monitoring tool to confirm the effect of bandwidth adjustment.
