Description

Technical Field

[0001] This invention relates to the field of Internet of Things (IoT) technology, and in particular to a method, apparatus, and electronic device for collaborative traffic control of IoT platform applications. Background Technology

[0002] The IoT platform ensures reliable access, efficient processing, and real-time transmission of massive amounts of device data, providing real-time data for upper-layer applications. These applications then leverage this real-time data to drive business decisions, automate processes, improve efficiency and user experience, ultimately transforming data value into tangible business results. The close collaboration between the IoT platform and applications constitutes a responsive and intelligently interconnected IoT solution, widely used in IoT project scenarios.

[0003] In IoT projects, the IoT platform is responsible for collecting and pushing data from devices in real time, while downstream application services receive messages and implement business logic. In the event of a sudden device failure, the data reporting rate surges dramatically. At this time, both the IoT platform and applications face significant pressure. How to effectively control traffic and prevent the IoT platform and applications from crashing becomes a pressing issue that needs to be addressed. Summary of the Invention

[0004] The purpose of this invention is to at least partially solve one of the technical problems existing in the prior art.

[0005] Therefore, one objective of this invention is to provide a method for collaborative control of application traffic on an IoT platform. This method dynamically divides and controls the traffic of input messages in real time based on the ratio of the application layer traffic threshold to the application ingress traffic value and the device identifier hash value of the input messages at the IoT platform layer. This enables traffic limiting at the southbound ingress of the IoT platform layer, preventing the IoT platform layer and application layer from becoming paralyzed and improving the stability of IoT services.

[0006] Another objective of this invention is to provide an IoT platform application traffic collaborative control device.

[0007] To achieve the above-mentioned technical objectives, the technical solutions adopted in the embodiments of the present invention include:

[0008] On one hand, embodiments of the present invention provide a method for coordinated traffic control of IoT platform applications, applied to the IoT platform layer, the IoT platform layer including a southbound access processing module, a northbound message push module, and a traffic monitoring and control system, the method for coordinated traffic control of IoT platform applications includes the following steps:

[0009] The system obtains the application ingress traffic value at the application layer through the traffic monitoring and control system, and calculates a first ratio between a preset application layer traffic threshold and the application ingress traffic value.

[0010] When the first ratio is less than 1, the first ratio is sent to the southbound access processing module through the traffic monitoring and control system;

[0011] The southbound access processing module obtains the device identifier of the input message, calculates the corresponding identifier hash value based on the device identifier, and divides the input message into retained messages and discarded messages based on the identifier hash value and the first ratio.

[0012] The southbound access processing module discards the discarded message and sends the retained message to the northbound message push module, which then pushes the retained message to the application layer.

[0013] Furthermore, in one embodiment of the present invention, the step of dividing the input message into retained messages and discarded messages based on the identifier hash value and the first ratio specifically includes:

[0014] Calculate the remainder after dividing the identifier hash value by 100, and calculate the product of the first ratio and 100;

[0015] Determine the closed interval from 1 to the product as the target interval;

[0016] When the remainder is within the target interval, the corresponding input message is determined to be a reserved message;

[0017] When the remainder is outside the target interval, the corresponding input message is determined to be a discard message.

[0018] Furthermore, in one embodiment of the present invention, the discarding process for the discarded message specifically includes:

[0019] The protocol gateway layer of the southbound access processing module discards the discarded messages and records the number of messages discarded.

[0020] The number of messages dropped is fed back to the traffic monitoring and control system.

[0021] Furthermore, in one embodiment of the present invention, the IoT platform application traffic collaborative control method further includes the following steps:

[0022] Obtain the southbound inbound traffic value and message drop count of the southbound access processing module, and calculate the message drop ratio based on the number of dropped messages and the southbound inbound traffic value;

[0023] When the sum of the message discard ratio and the first ratio is greater than 1, the value of the right endpoint of the target interval is increased to make the target interval larger;

[0024] When the sum of the message discard ratio and the first ratio is less than 1, the value of the right endpoint of the target interval is reduced to make the target interval smaller.

[0025] Furthermore, in one embodiment of the present invention, sending the reserved message to the northbound message push module, so that the northbound message push module pushes the reserved message to the application layer, specifically includes:

[0026] The reserved message is decoded by the southbound access processing module, and the decoded reserved message is sent to the northbound message push module.

[0027] The decoded retained message is pushed to the application layer through the northbound message push module, and the northbound outbound traffic value is recorded.

[0028] The northbound exit flow rate value is fed back to the flow monitoring and control system.

[0029] On the other hand, embodiments of the present invention provide an IoT platform application traffic coordination control device, applied at the IoT platform layer, including a southbound access processing module, a northbound message push module, and a traffic monitoring and control system, wherein:

[0030] The traffic monitoring and control system is used to obtain the application ingress traffic value of the application layer, calculate the first ratio of the preset application layer traffic threshold to the application ingress traffic value, and when the first ratio is less than 1, send the first ratio to the southbound access processing module.

[0031] The southbound access processing module is used to obtain the device identifier of the input message, calculate the corresponding identifier hash value based on the device identifier, divide the input message into a retained message and a discarded message based on the identifier hash value and the first ratio, discard the discarded message, and send the retained message to the northbound message push module.

[0032] The northbound message push module is used to push the reserved message to the application layer.

[0033] Furthermore, in one embodiment of the present invention, the southbound access processing module includes:

[0034] The first calculation unit is used to calculate the remainder after dividing the identifier hash value by 100, and to calculate the product of the first ratio and 100;

[0035] An interval determination unit is used to determine the closed interval from 1 to the product as the target interval;

[0036] The message segmentation module is used to determine that the corresponding input message is a retained message when the remainder is within the target interval, and to determine that the corresponding input message is a discarded message when the remainder is outside the target interval.

[0037] Furthermore, in one embodiment of the present invention, the southbound access processing module further includes:

[0038] The second calculation unit is used to obtain the southbound inbound traffic value and the number of messages dropped, and to calculate the message drop ratio based on the number of dropped messages and the southbound inbound traffic value.

[0039] An interval adjustment unit is used to increase the value of the right endpoint of the target interval to make the target interval larger when the sum of the message discard ratio and the first ratio is greater than 1, and to decrease the value of the right endpoint of the target interval to make the target interval smaller when the sum of the message discard ratio and the first ratio is less than 1.

[0040] On the other hand, embodiments of the present invention provide an electronic device, which includes a memory, a processor, a computer program stored in the memory and executable on the processor, and a data bus for implementing communication between the processor and the memory. When the computer program is executed by the processor, it implements the IoT platform application traffic collaborative control method as described above.

The storage medium stores one or more computer programs, which can be executed by one or more processors to implement the IoT platform application traffic collaborative control method as described above.

[0042] On the other hand, embodiments of the present invention also provide a computer program product, including a computer program that, when executed by a processor, implements the IoT platform application traffic collaborative control method as described above.

[0043] The advantages and beneficial effects of the present invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention:

[0044] This invention employs a traffic monitoring and control system to obtain application ingress traffic values ​​at the application layer and calculates a first ratio between a preset application layer traffic threshold and the application ingress traffic value. When the first ratio is less than 1, the traffic monitoring and control system sends this ratio to the southbound access processing module. The southbound access processing module obtains the device identifier of the input message, calculates the corresponding identifier hash value based on the device identifier, and divides the input message into retained messages and discarded messages based on the identifier hash value and the first ratio. The southbound access processing module discards the discarded messages and sends the retained messages to the northbound message push module, enabling the northbound message push module to push the retained messages to the application layer. This invention dynamically divides and controls the traffic of input messages in real time based on the ratio of the application layer traffic threshold to the application ingress traffic value and the device identifier hash value of the input message at the IoT platform layer. This enables rate limiting at the southbound ingress of the IoT platform layer, preventing the IoT platform layer and application layer from becoming paralyzed and improving the stability of IoT services.

[0061] like Figure 1 The diagram shown is a flowchart of a traffic collaborative control method for an IoT platform application provided by an embodiment of the present invention. (Refer to...) Figure 1 This invention provides a method for coordinated traffic control of IoT platform applications, applied to the IoT platform layer. The IoT platform layer includes a southbound access processing module, a northbound message push module, and a traffic monitoring and control system. The method for coordinated traffic control of IoT platform applications includes the following steps:

[0062] S101. Obtain the application ingress traffic value of the application layer through the traffic monitoring and control system, and calculate the first ratio between the preset application layer traffic threshold and the application ingress traffic value.

[0063] S102. When the first ratio is less than 1, the first ratio is sent to the southbound access processing module through the traffic monitoring and control system.

[0064] S103. Obtain the device identifier of the input message through the southbound access processing module, calculate the corresponding identifier hash value based on the device identifier, and divide the input message into retained messages and discarded messages based on the identifier hash value and the first ratio.

[0065] S104. The southbound access processing module discards the messages and sends the retained messages to the northbound message push module, so that the northbound message push module pushes the retained messages to the application layer.

[0066] Specifically, the embodiments of the present invention adopt a three-layer architecture of "terminal-IoT platform-application" and deploy a traffic monitoring and control system (FMCS) at the IoT platform layer to form a "business + control" dual plane.

[0067] The terminal layer consists of several IoT terminal devices with network communication capabilities, supporting southbound protocols such as MQTT, CoAP, and HTTP, and periodically / event-based reporting of business data.

[0068] The IoT platform layer includes:

[0069] 1) Southbound Access Processing Module

[0070] Protocol gateway: performs protocol parsing and data decoding;

[0071] Device authentication: Based on device certificate / key authentication;

[0072] Flow control unit: Receives the first proportion issued by FMCS and executes a hash-based packet loss strategy.

[0073] 2) Northbound message push module: Pushes processed messages to business applications in real time through channels such as Kafka / MQ.

[0074] 3) Traffic monitoring interface

[0075] South entrance monitoring point: Counts the number of messages received per second (S) in ;

[0076] Northbound exit monitoring point: Counts the number of messages pushed per second (S) out .

[0077] 4) Traffic Flow Monitoring and Control System (FMCS)

[0078] Acquisition end: Based on Prometheus Exporter, Fluent Bit, or eBPF probes, for S in S out A in Implement data embedding;

[0079] Calculation end: Based on the user-preset application layer traffic threshold Y, the first proportion r = (Y / y) * 100% is calculated in real time, where y = A in ;

[0080] Alarm terminal: When r < 100%, a flow control command is triggered, and r is sent to the "Southbound Access Processing Module" via the REST / gRPC interface.

[0081] The application layer receives structured messages by subscribing to topics, and simultaneously deploys application-side monitoring and data collection points to count the number of messages (A) entering the application layer per second. in .

[0082] It can be recognized that, according to the embodiment of the present invention, the input message is dynamically divided and the traffic is controlled in real time based on the ratio of the application layer traffic threshold to the application ingress traffic value and the device identifier hash value of the input message of the IoT platform layer. This enables the flow restriction at the southbound ingress of the IoT platform layer, avoids the paralysis of the IoT platform layer and the application layer, and improves the stability of IoT services.

[0083] like Figure 2 The diagram shown is a flowchart of step S103 provided in an embodiment of the present invention. (Refer to...) Figure 2 As an optional implementation, the input message is further divided into retained messages and discarded messages based on the identifier hash value and a first ratio, specifically including:

[0084] S1031. Calculate the remainder after dividing the identifier hash value by 100, and calculate the product of the first ratio and 100;

[0085] S1032. Determine the closed interval from 1 to the product as the target interval;

[0086] S1033. When the remainder is within the target interval, determine the corresponding input message as a reserved message;

[0087] S1034. When the remainder is outside the target interval, determine that the corresponding input message is a discard message.

[0088] Specifically, the user enters the application-side entry alarm threshold Y (unit: alarms / second) in the FMCS configuration interface. FMCS then starts a background data collection thread, which retrieves metrics from each monitoring point at intervals of ΔT (default 1 second). The collected real-time application-side traffic is recorded as y=A. inThe first ratio is calculated as r = (Y / y) × 100%, rounded down to two decimal places. If r ≥ 100%, it indicates that the application side is not overloaded, and FMCS only logs and does not issue flow control commands. If r < 100%, FMCS pushes r to the southbound access processing module in real time through gRPC Stream. The southbound access processing module executes a hash-based packet loss strategy based on the first ratio issued by FMCS. After flow control, the message is sent to the business application through the northbound push module, thereby ensuring that the application-side ingress traffic is less than the application layer traffic threshold and achieving controllable system load.

[0089] Specifically, for each southbound message, its device identifier device_id is taken, and a 32-bit FNV-1ahash is calculated to obtain the identifier hash value h; the remainder after dividing the identifier hash value by 100 is calculated, i.e., m=h mod100, to obtain an integer from 0 to 99; if m falls within the interval [1, 100r], the message will normally enter the subsequent decoding, storage, and push process; otherwise, it will be directly discarded at the protocol gateway layer and the discard count will be recorded.

[0090] It can be recognized that traditional practices only implement rate limiting or circuit breaking on the application side. This embodiment of the invention drops packets "in advance" at the southbound entry point of the IoT platform, greatly reducing invalid network and internal platform processing overhead. Traditional practices discard data randomly or at the topic level. This embodiment of the invention divides messages based on device identifier hash values, ensuring consistency of multiple samples from the same device, avoiding "false positives" on critical devices, and improving fairness. Traditional practices manually configure alarm thresholds statically, which cannot be adjusted according to business peaks and valleys. This embodiment of the invention calculates the first ratio in real time and dynamically distributes it, achieving automatic rate limiting during business peaks and automatic recovery during valleys through closed-loop adjustment. Traditional practices only issue alarms through the monitoring platform, requiring manual intervention. This embodiment of the invention's FMCS and the platform's southbound access module work together in real time to automatically execute rate limiting, shortening the response time from "minutes" to "seconds".

[0091] This invention deploys the "monitoring-decision-execution" process as a lightweight, hot-swappable bypass pipeline, which maintains ease of use in scenarios with massive IoT terminal access while significantly reducing operation and maintenance and development costs. It is particularly suitable for IoT platforms and application environments that require 24 / 7 high availability but have limited manpower.

[0092] like Figure 3 The diagram shown is a flowchart of step S104 provided in an embodiment of the present invention. (Refer to...) Figure 3 As an optional implementation, the discarded messages are further processed by discarding them, specifically including:

[0093] S1041. In the protocol gateway layer of the southbound access processing module, discard messages and record the number of messages discarded.

[0094] S1042. Feedback the number of messages dropped to the traffic monitoring and control system.

[0095] like Figure 4 The diagram shown is another step flowchart of the IoT platform application traffic collaborative control method provided in this embodiment of the invention. (Refer to...) Figure 4 As an optional implementation, the IoT platform application traffic collaborative control method further includes the following steps:

[0096] S201. Obtain the southbound inbound traffic value and message drop count of the southbound access processing module, and calculate the message drop ratio based on the message drop count and the southbound inbound traffic value.

[0097] S202. When the sum of the message discard ratio and the first ratio is greater than 1, increase the value of the right endpoint of the target interval to make the target interval larger.

[0098] S203. When the sum of the message discard ratio and the first ratio is less than 1, reduce the value of the right endpoint of the target interval to make the target interval smaller.

[0099] Specifically, the southbound access processing module calculates the message discard ratio based on the number of discarded messages and the southbound inbound traffic value. When the sum of the message discard ratio and the first ratio is greater than 1, it indicates that too many messages have actually been discarded. The value of the right endpoint of the target interval can be appropriately increased based on the preset ratio to make the target interval larger, so that more input messages can be retained and pushed to the application layer. When the sum of the message discard ratio and the first ratio is less than 1, it indicates that too few messages have actually been discarded. The value of the right endpoint of the target interval can be appropriately decreased based on the preset ratio to make the target interval smaller, so that more input messages can be discarded and prevent the application layer traffic from exceeding the threshold.

[0100] like Figure 5 The diagram shown is another flowchart of step S104 provided in an embodiment of the present invention. (Refer to...) Figure 5 As an optional implementation, the retained message is sent to the northbound message push module, which then pushes the retained message to the application layer. This specifically includes:

[0101] S1043. The reserved message is decoded by the southbound access processing module and the decoded reserved message is sent to the northbound message push module.

[0102] S1044. Push the decoded retained message to the application layer through the northbound message push module, and record the northbound outbound traffic value;

[0103] S1045. Feed back the northbound exit flow rate value to the flow monitoring and control system.

[0104] This invention moves the flow control action forward to the southbound entry point of the IoT platform. Based on the ratio of the application layer flow threshold to the application entry flow value, the original input message is directly dropped. This can complete peak shaving before the data enters the internal link of the platform, significantly reducing invalid network transmission and internal computing overhead.

[0105] The traffic monitoring and control system of this invention collects application layer inbound traffic values, calculates the ratio of application layer traffic threshold to application inbound traffic value in real time, and immediately sends the data to the southbound access processing module when the ratio is less than 1. It can achieve second-level automatic adjustment, dynamic degradation during peak business hours and automatic recovery during off-peak hours, without the need for manual intervention.

[0106] This invention calculates a hash value based on the device identifier to distinguish between discarded and retained messages, maintaining consistent packet loss results within the same device's lifecycle. This avoids "false positives" from random or topic-level packet loss strategies that could "kill" critical devices, ensuring sampling continuity and business fairness.

[0107] In this embodiment of the invention, the monitoring probe and protocol gateway are completely decoupled, the terminal does not need to upgrade the firmware, the threshold and policy are hot-updated via REST / gRPC, it can support new protocols and new devices to be accessed with zero development, and the operation and maintenance personnel can "configure and take effect immediately", which significantly reduces deployment and maintenance costs.

[0108] The method flow of the embodiments of the present invention has been described above. It can be understood that the embodiments of the present invention dynamically divide and control the traffic of input messages in real time based on the ratio of the application layer traffic threshold to the application ingress traffic value and the device identifier hash value of the input messages at the IoT platform layer. This enables rate limiting at the southbound ingress of the IoT platform layer, preventing paralysis of the IoT platform layer and the application layer, and improving the stability of IoT services.

[0109] like Figure 6 The diagram shown is a structural schematic of the IoT platform application traffic collaborative control device provided in an embodiment of the present invention. (Refer to...) Figure 6 This invention provides an IoT platform application traffic coordination control device, applied at the IoT platform layer, including a southbound access processing module, a northbound message push module, and a traffic monitoring and control system, wherein:

[0110] The traffic monitoring and control system is used to obtain the application ingress traffic value of the application layer, calculate the first ratio of the preset application layer traffic threshold to the application ingress traffic value, and when the first ratio is less than 1, send the first ratio to the southbound access processing module.

[0111] The southbound access processing module is used to obtain the device identifier of the input message, calculate the corresponding identifier hash value based on the device identifier, divide the input message into retained messages and discarded messages based on the identifier hash value and a first ratio, discard the discarded messages, and send the retained messages to the northbound message push module.

[0112] The northbound message push module is used to push retained messages to the application layer.

[0113] like Figure 7 The diagram shown is a structural schematic of a southbound access processing module provided in an embodiment of the present invention. (Refer to...) Figure 7 As an optional implementation, the southbound access processing module includes:

[0114] The first calculation unit is used to calculate the remainder after dividing the identifier hash value by 100, and to calculate the product of the first ratio and 100;

[0115] Interval determination unit, used to determine the closed interval from 1 to the product as the target interval;

[0116] The message segmentation module is used to determine that when the remainder is within the target interval, the corresponding input message is a retained message, and when the remainder is outside the target interval, the corresponding input message is a discarded message.

[0117] like Figure 8 The diagram shown is another structural schematic of the southbound access processing module provided in an embodiment of the present invention. (Refer to...) Figure 8 As an optional implementation, the southbound access processing module further includes:

[0118] The second calculation unit is used to obtain the southbound inbound traffic value and the number of messages dropped, and to calculate the message drop ratio based on the number of dropped messages and the southbound inbound traffic value.

[0119] The interval adjustment unit is used to increase the value of the right endpoint of the target interval when the sum of the message discard ratio and the first ratio is greater than 1, so that the target interval becomes larger; and to decrease the value of the right endpoint of the target interval when the sum of the message discard ratio and the first ratio is less than 1, so that the target interval becomes smaller.
