[0046] To make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the embodiments of the present application will be described in detail below in conjunction with the accompanying drawings. However, it will be appreciated by those skilled in the art that in the present application, many technical details are proposed in order to enable the reader to better understand the present application. However, even without these technical details and various changes and modifications based on the following embodiments, the technical scheme claimed in the present application can also be implemented. The division of the following embodiments is for the convenience of description, and the specific implementation of the present application should not be construed as any limitation, and the various embodiments can be combined and referenced with each other under the premise of no contradiction.

[0047] In order to facilitate understanding of the embodiments of the present application, relevant content about message agent transmission is first introduced here.

[0048] With the rapid development of Internet of Things (IoT) technology, the MQTT (Message Queuing Telemetry Transport) protocol, as a lightweight publish / subscribe message transmission protocol, has been widely used in scenarios with limited bandwidth and limited device resources. However, in practical applications, the load pressure of the MQTT server often changes with the increase in the number of devices and the fluctuation of the network transmission rate, which poses a severe challenge to the stability of the server and the efficiency of message processing. When using the MQTT protocol to transmit information, the server usually transmits to multiple devices. As the number of devices increases and the network transmission rate fluctuates, the load pressure of the MQTT server will fluctuate. The existing technology usually relies on fixed routing algorithms and preset network configurations to adjust the load, but the real-time network environment fluctuates greatly. The existing technology cannot dynamically adapt to the real-time changing network transmission environment, resulting in large fluctuations in server load pressure, affecting operational stability, and may reduce message processing efficiency and affect message transmission speed.

[0049] In order to solve the above-mentioned technical problem that the large fluctuation of proxy service load pressure affects the operation stability, the present invention proposes a method for adjusting the transmission rate of a proxy service channel. The implementation details of the method for adjusting the transmission rate of the proxy service channel of this embodiment are specifically described below. The following content is only the implementation details provided for the convenience of understanding and is not necessary for the implementation of this solution.

[0050] Embodiment 1:

[0051] The method for adjusting the transmission rate of the proxy service channel of this embodiment can be applied to electronic devices with communication, computing and data storage capabilities. In this embodiment, the proxy service channel is described as a transmission channel between the MQTT proxy service and the smart device. The method for adjusting the transmission rate of the proxy service channel can be as follows: Figure 1 and Figure 5As shown, steps 101-104 are included, specifically including:

[0052] Step 101, obtaining at least one of an average value, a maximum value and a minimum value of historical transmission rates respectively corresponding to a plurality of transmission channels; the plurality of transmission channels are transmission channels respectively corresponding to the proxy service and each device.

[0053] Specifically, the execution subject of the method can be a server that provides a rate adjustment service for the transmission channel between the proxy service and the device, or a server of the proxy service; wherein the proxy service can actively report and send data. In this embodiment, the proxy service is described by taking the MQTT proxy service as an example. The MQTT proxy service actively reports and sends data, and the data elements included are: MAC, device type, send / report type, data packet size (bytes), time of sending and reporting data, etc.

[0054] Among them, the proxy service can establish transmission channels with multiple devices respectively. In this solution, multiple transmission channels are transmission channels corresponding to the proxy service and each device, which is convenient for comprehensive evaluation of the overall data transmission pressure of the proxy service, and then provides adaptive adjustment to reduce server load pressure.

[0055] In some examples, step 101, such as Figure 2 As shown, specifically including:

[0056] Step 1011, obtaining historical transmission data corresponding to the plurality of transmission channels in a period;

[0057] Step 1012: Calculate at least one of an average value, a maximum value, and a minimum value of historical transmission rates corresponding to a plurality of transmission channels respectively using the historical transmission data.

[0058] Specifically, the historical transmission data includes the size of the sent data packet, the size of the reported data packet, the sending time and the reporting time in the transmission channel. The corresponding time corresponding to the transmission channel is obtained by subtracting the reporting time from the sending time, so that the transmission rate can be calculated by the following calculation formula:

[0059] Rate (bytes / second) = (download data packet size + reported data packet size) / (download time - reporting time) (seconds).

[0060] By statistically analyzing the historical transmission data in the period, the historical transmission rate average value, maximum value and minimum value are obtained, which are used as the threshold standards in the future preset time in turn. After the preset time expires, the historical transmission rate average value, maximum value and minimum value are updated based on the historical transmission data in the period to obtain the latest standard, so as to improve the accuracy of the subsequent dynamic adjustment of the transmission rate. In this embodiment, the period can be set to seven days as a period, and the future preset time is one month, so as to regularly update the historical transmission rate average value, maximum value and minimum value.

[0061] In this embodiment, the multiple transmission channels formed between the proxy service and each device are analyzed separately to form the corresponding historical transmission rate average, maximum and minimum values ​​for each transmission channel, so that each transmission channel can be monitored and dynamically adjusted to ensure the load balance of the entire proxy service.

[0062] Step 102: Obtain actual transmission rates currently corresponding to the multiple transmission channels.

[0063] Specifically, the actual transmission rate is calculated based on statistical analysis of the real-time transmission data collected during the preset time period of the transmission channel corresponding to the connection between the current proxy service and each device, and combined with the rate calculation formula in the aforementioned step 1012. In this embodiment, the preset time period can be set to one hour or half an hour, and the user can set the data collection time period for calculating the actual transmission rate according to actual usage needs.

[0064] Step 103: determining a transmission pressure level of the current proxy service according to the actual transmission rates of the plurality of transmission channels and at least one of an average value, a maximum value and a minimum value of corresponding historical transmission rates.

[0065] Specifically, by comparing the actual transmission rate with the historical average, maximum, and minimum transmission rates, we can analyze the pressure that the current actual transmission rate brings to the transmission channel, and then determine the transmission pressure level of the current proxy service.

[0066] In some examples, the transmission pressure level is configured with at least two different levels, and the transmission pressure levels of different levels are respectively preset with corresponding adjustment algorithms. The transmission pressure levels of different levels have at least a certain span, so that corresponding adjustment algorithms can be provided for high pressure and low pressure to regulate the transmission rate.

[0067] Based on the setting of multiple transmission pressure levels, step 103 specifically includes: analyzing and matching the actual transmission rates of the multiple transmission channels and at least one of the corresponding historical transmission rate averages, maximum values ​​and minimum values ​​in order of transmission pressure levels from high to low until the corresponding pressure level conditions are matched, thereby determining the overall transmission pressure level of the proxy service.

[0068] Specifically, when analyzing and determining the transmission pressure level, the transmission pressure level is identified and analyzed in sequence from high to low, and the high-pressure transmission pressure level can be checked first, and then the corresponding transmission rate can be dynamically adjusted to balance the load pressure, thereby improving the effect of real-time dynamic adjustment of the transmission rate and promptly alleviating the load pressure of the server.

[0069] In some embodiments, step 103, such as Figure 4 As shown, specifically including:

[0070] Step 1032: Perform transmission pressure analysis by using the actual transmission rate of each transmission channel and at least one of the corresponding historical transmission rate average value, maximum value and minimum value in turn to determine the current channel pressure of each transmission channel;

[0071] Step 1033: Determine the current transmission pressure level of the entire proxy service according to the current channel pressure of each transmission channel.

[0072] Specifically, by analyzing the current channel pressure of each transmission channel, it is possible to conveniently monitor the overall data transmission pressure between the proxy service and each device, and then accurately evaluate the current overall transmission pressure level of the proxy service, which is conducive to accurately providing adaptive adjustments, effectively balancing the load, and improving the reliability and efficiency of message transmission, and reducing transmission delays.

[0073] Step 104 : Matching a corresponding adjustment algorithm based on the transmission pressure level of the current proxy service, and adjusting the transmission rate of each transmission channel through the adjustment algorithm.

[0074] Specifically, different transmission pressure levels are matched with different adjustment algorithms, so that the transmission rate of each transmission channel is adjusted using the corresponding adjustment algorithm, thereby realizing dynamic adjustment of the transmission rate of the proxy transmission channel.

[0075] By providing corresponding rate adjustment algorithms for each level of transmission pressure, the proxy service can achieve a balance within the preset value range, and based on the real-time monitoring of the number of network transmissions, it can dynamically adjust the pressure level used, and then adapt the corresponding adjustment algorithm to achieve dynamic adjustment of the channel transmission rate of the MQTT proxy, thereby ensuring the reliability of message transmission while effectively alleviating the load pressure of the MQTT server and improving message processing efficiency.

[0076] This embodiment can determine the transmission pressure level corresponding to the actual transmission rate of each transmission channel of the current proxy service based on the historical transmission rate average, maximum and minimum values, and then dynamically adjust the transmission rate of each transmission channel through an adjustment algorithm that matches the corresponding transmission pressure level, effectively balance the load, improve the reliability and efficiency of message transmission, and reduce transmission delay.

[0077] In some embodiments, the overall transmission pressure level of the proxy service is configured as three levels, that is, the transmission pressure levels include a high-pressure transmission pressure level, a medium-pressure transmission pressure level, and a low-pressure transmission pressure level in order from high to low. For different transmission pressure levels, corresponding determination conditions are preset. Specifically, the high-pressure transmission pressure level, the medium-pressure transmission pressure level, and the low-pressure transmission pressure level are respectively provided with a high-pressure condition, a medium-pressure condition, and a low-pressure condition for determining the pressure level.

[0078] Based on the three configured transmission pressure levels, when analyzing the transmission pressure level of the current proxy service, such as Figure 3 As shown, it specifically includes: 1031, analyzing and matching the actual transmission rates of the multiple transmission channels and at least one of the corresponding historical transmission rate average, maximum and minimum values ​​with the high pressure condition, medium pressure condition and low pressure condition in order of transmission pressure level from high to low, until the corresponding conditions are matched, to determine the overall transmission pressure level of the proxy service.

[0079] Through high pressure conditions, medium pressure conditions and low pressure conditions, the actual transmission rate can be directly compared with the average, maximum and minimum values ​​of the historical transmission rate, so as to quickly analyze the pressure conditions matching the actual transmission rate, and then quickly determine the corresponding transmission pressure level, thereby improving the efficiency and accuracy of determining the transmission pressure level of the proxy service.

[0080] In some examples, the high-pressure condition includes a transmission channel among the multiple transmission channels having an actual transmission rate less than the minimum historical transmission rate; the adjustment algorithm corresponding to the high-pressure transmission pressure level includes: limiting the transmission rate of the transmission channel in the proxy service whose actual transmission rate is greater than the maximum historical transmission rate to the average historical transmission rate through traffic shaping.

[0081] In some examples, the medium pressure condition includes that the total number of transmission channels whose actual transmission rate is less than the average value of the historical transmission rate in the plurality of transmission channels is greater than a first preset ratio threshold; the adjustment algorithm corresponding to the medium pressure transmission pressure level includes: selecting a preset number of transmission channels from the plurality of transmission channels whose actual transmission rate is greater than the average value of the historical transmission rate in the proxy service in sequence, and limiting the transmission rate of the selected transmission channels to the average value of the historical transmission rate through traffic shaping, until the proportion of the number of transmission channels whose actual transmission rate is less than the average value of the historical transmission rate to the total number of transmission channels is less than or equal to a third preset ratio threshold;

[0082] In some examples, the low-pressure condition includes that the total number of transmission channels in the multiple transmission channels whose actual transmission rate is less than the historical transmission rate average is less than a second preset ratio threshold; the adjustment algorithm corresponding to the low-pressure transmission pressure level includes: releasing the preset transmission rate of the transmission channels in the proxy service whose actual transmission rate is lower than the historical transmission rate average in sequence, until the number of transmission channels in the proxy service whose actual transmission rate is lower than the historical transmission rate average accounts for a proportion of the total number of transmission channels in the proxy service that is less than or equal to a fourth preset ratio threshold.

[0083] In some specific embodiments, Figure 5 As shown, the actual transmission rate of the transmission channel that is less than the corresponding minimum historical transmission rate is recorded as a high-pressure condition, and the current server is further determined to have channel pressure. The number of channels with "channel rate greater than the maximum value" is counted, and these channels use the "traffic shaping processor" method to limit the transmission rate (maximum read and write rate) to the average value, thereby reducing the rate and lowering the speed of some traffic.

[0084] "The proportion of transmission channels with actual transmission rate lower than the average value of historical transmission rate to the total number of channels is greater than 50%" is taken as the medium pressure condition, and the number of channels with "channel transmission rate greater than the average value" is counted. For these channels, the transmission rate (maximum read and write rate) is limited to the average value using the "traffic shaping processor" method for 25% of the channels each time, until the proportion of channels with channel transmission rate lower than the average value to the total number of channels is less than or equal to 20%. In this case, speed limit will no longer be performed, the rate will be reduced, and the speed of some traffic will be reduced.

[0085] "The proportion of channels with channel transmission rates lower than the average to the total number of channels is less than 10%" is set as the low-pressure condition. The number of channels for which the server has set rate limits is counted, and 10% of the channel read and write rate limits are released each time until the proportion of channels with channel transmission rates lower than the average to the total number of channels is less than or equal to 2%. No more releases are made, and a balance is achieved within the preset value range.

[0086] Among them, traffic shaping is a more fine-grained flow control method that allows developers to limit the reading and sending rates of data according to business needs. ChannelTrafficShapingHandler: Netty provides this processor to limit the traffic of a single channel. It can control the data transmission speed according to the configured maximum read rate and maximum write rate. The traffic shaping processor implements flow control by calculating waiting time and using timed tasks to ensure that the average rate meets the settings.

[0087] In some embodiments, the proxy service channel transmission rate adjustment method, such as Figure 6 As shown, it also includes:

[0088] Step 201, obtaining user input adjustment data;

[0089] Step 202: adjusting at least one of the adjustment algorithms corresponding to the high pressure condition, the medium pressure condition, the low pressure condition and each transmission pressure level according to the adjustment data.

[0090] Specifically, the adjustment data input by the user is the feedback from the user after a period of use experience. In this embodiment, the execution subject of step 201 may be a server.

[0091] Among them, at least one of the adjustment algorithms corresponding to the high pressure conditions, medium pressure conditions, low pressure conditions and each transmission pressure level is adjusted according to the adjustment data, and the relevant preset proportional thresholds in the adjustment algorithms corresponding to the high pressure conditions, medium pressure conditions, low pressure conditions and each transmission pressure level are adjusted, so that the server load balancing value can be adjusted in combination with the actual needs of the user, providing a transmission rate that meets the user's usage needs and improving the user experience.
