Description

Software-based network congestion control method, device and storage medium Technical Field

[0001] The present invention relates to the fields of edge computing and distributed control, and in particular to a software-based network congestion control method, device, and storage medium. Background Art

[0002] With the development of the Industrial Internet of Things (IIoT) and the convergence of IT and Operational Technology (OT), numerous hierarchical distribution systems have been developed and deployed in production sites such as smart factories, smart buildings, and smart mines to provide scalable, upgradeable, and manageable low-latency, reliable industrial applications and services. These hierarchical systems typically consist of one or more control points located within the central IT infrastructure of a factory or building. Equipment, distributed throughout production lines, plant buildings, and mines, receives instructions and commands from the control points and reports its status and data based on application requirements. Consequently, significant data traffic occurs between the various equipment and control points. In scenarios with relatively good network conditions, such as smart factories and smart buildings, this data traffic does not pose a significant problem. However, many hierarchical distribution systems are not specifically designed for scenarios with poor network conditions between equipment and control points, such as water plants and mines. When equipment updates applications or executes instructions, control points often encounter network errors. If the equipment doesn't receive the information it needs, they retry connections, which only worsens the situation and can lead to damage to the control points. Furthermore, connections in the distribution system are initiated by different applications developed by different developers. Redeveloping all applications requires extensive work and is sometimes impractical. Finally, the priority of traffic is not taken into account. In some cases, high-priority traffic, such as error reports and status changes, must wait for low-priority traffic, such as software updates, to complete, resulting in the loss of important data.

[0003] Summary of the Invention

[0004] To solve the above problems, the present invention proposes a software-based network congestion control method, device and storage medium to control and schedule data in the network and cache data when the network is blocked, thereby avoiding the occurrence of network congestion and ensuring the flexibility and stability of the network.

[0005] A device anomaly location method proposed in an embodiment of the present invention includes: acquiring and storing transmission data from at least one application within the device; scheduling the transmission data, including prioritizing the stored transmission data based on predefined priority rules and pushing the transmission data according to the priority classification order and predefined scheduling rules; and transmitting the transmission data, including transmitting the pushed transmission data to a control node. This method enables the control and scheduling of data within the network without the need for cooperation from third-party software developers, avoids network congestion, and ensures network flexibility and stability.

[0006] In one embodiment, the method of pushing the transmission data according to the priority classification order and predefined scheduling rules further includes: the priority classification includes immediate transmission data and non-immediate transmission data; the immediate transmission data is pushed first, and the non-immediate transmission data is pushed later; the scheduling rules include the network retention time and network blocking status of the transmission data; and the transmission data is pushed within the network retention time and when the network blocking status is not blocked. This achieves data transmission according to the priority importance of the data and caches the data when the network is blocked, further avoiding the occurrence of network congestion and ensuring the flexibility and stability of the network.

[0007] In one embodiment, the method further includes: scheduling received data, obtaining received data from a control node, and determining whether a communication port within the device is occupied; if so, transmitting the received data to a corresponding application after the port is unoccupied; if not, directly transmitting the received data to the corresponding application. This allows for temporary suspension of data reception when a network is blocked, preventing data loss and ensuring system reliability.

This device controls and schedules data within the network, avoids network congestion, and ensures network flexibility and stability.

[0009] In one embodiment, the method of pushing the transmission data according to the priority classification order and predefined scheduling rules further includes: the priority classification includes immediate transmission data and non-immediate transmission data; the immediate transmission data is pushed first, and the non-immediate transmission data is pushed later; the scheduling rules include the network retention time and network blocking status of the transmission data; and the transmission data is pushed within the network retention time and when the network blocking status is not blocked. This achieves data transmission according to the priority importance of the data and caches the data when the network is blocked, further avoiding the occurrence of network congestion and ensuring the flexibility and stability of the network.

[0018] The following are the descriptions of the reference numerals: DETAILED DESCRIPTION

[0019] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, specific embodiments of the present invention are now described with reference to the accompanying drawings.

[0020] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0021] As used in this application and the claims, unless the context clearly indicates otherwise, the words "a," "an," "an," and / or "the" are not intended to refer to the singular but may include the plural. Generally speaking, the terms "comprises" and "include" only indicate the inclusion of the steps and elements specifically identified, and these steps and elements do not constitute an exclusive list. A method or apparatus may also include other steps or elements.

[0022] A typical distributed control system can be deployed in physical locations such as factories, buildings, mines, and water plants. Centralized IT infrastructure manages and controls edge devices (operating equipment) at the field level. These operating equipment is responsible for low-latency business applications such as monitoring and controlling field equipment. For example, in a building, edge devices run a set of applications that monitor sensor readings such as smoke detectors and temperature, and control fire extinguishers and air conditioners accordingly.

[0023] Several applications may be running on edge devices. These applications may need to upload data to or receive instructions from the central IT infrastructure. More specifically, these applications are not limited to business applications. System applications, such as system and application updates and configuration tools, also communicate with the central IT infrastructure. All applications independently initiate connections to the central IT infrastructure through the system's network stack, including routing tables. If network conditions are suboptimal, the lack of coordination between different applications can degrade application performance. For example, a working device may miss important instructions from the central IT infrastructure. The central IT infrastructure may also miss important notifications from working devices, such as emergencies and functional failures. Furthermore, constantly establishing too many connections can overwhelm the central IT infrastructure.

[0024] Therefore, an embodiment of the present invention provides a more optimized software-based network congestion control method, device and storage medium. The method includes: obtaining transmission data, obtaining and saving transmission data of at least one application in the device; scheduling transmission data, including: prioritizing the saved transmission data based on predefined priority rules, and pushing the transmission data according to the priority classification order and predefined scheduling rules; transmitting transmission data, transmitting the pushed transmission data to the control node. The technical solution in the embodiment of the present invention can control and schedule data in the network, and cache data when the network is blocked, thereby avoiding the occurrence of network congestion and ensuring the flexibility and stability of the network.

[0027] Specifically, from the application perspective, the application does not need to make any improvements and still maintains the regular port for data transmission. It only needs to continuously monitor the port to obtain the data sent by different applications for subsequent control.

[0028] Step S102 : scheduling the sending data, performing priority classification on the stored sending data based on a predefined priority rule, and pushing the sending data according to the priority classification order and the predefined scheduling rule.

For more complex implementations, data can be tagged with a numerical priority. Furthermore, communications can be retained by time and date. Furthermore, whether or not the communication is interruptible can be specified. All data tags are traversed, and data is pushed according to the tag requirements.

[0033] Specifically, the reception data of the control node can be scheduled, and the data of the control node can be received only when the normal port of the network is not occupied, thereby avoiding data loss.
