[0002] Network port data forwarding technology is widely used in remote access, multi-system collaboration and the like, but the existing scheme cannot meet the flexible adaptation requirement. Foreign mainstream tools such as ngrok and frp only support basic port mapping and cannot realize automatic data flow through a subscription relationship.

[0015] REFERENCE Figure 1The application relates to a port subscription type data forwarding method for data transceiving on-demand processing, and mainly relates to data receiving, data processing, data distribution, data subscription and data sending of a port. First, a port is newly added, the communication mode and data processing program of the port are set, and then the data subscription relationship between the ports is configured on-demand; when the port receives data through a data transceiving module, the data is first submitted to a data processing module for processing after being de-duplicated according to a line identifier; if the other ports need to be notified after the processing, the data is submitted to the data subscription module of the corresponding port through a data distribution module; when the port subscribes to data through the data subscription module, the data is first submitted to the data processing module for processing, and then the data is sent through a data sending module if the data needs to be forwarded after the processing.

[0016] The method comprises the following steps: Step 1: a port is newly added, and the communication mode, data processing program and other port information of the port are set.

[0017] The port information comprises a port identifier, a port name, a line identifier, a communication mode, a local network address, a local network port, a remote network address, a remote network port, TTL and a data processing program dynamic library file path, wherein the communication mode supports UDP unicast, broadcast and multicast.

[0018] The line identifier is used to aggregate multiple ports into one port, and when the ports with the same line identifier receive the same data, the processing is only performed at the first time.

[0019] The data processing program refers to a data processing dynamic library, supports dynamic loading, each port can be configured with a data processing dynamic library, provides the processing function of the data received from the data receiving module and the data subscribed from the data subscription module, and supports discarding data on-demand.

[0020] Step 2: the data subscription relationship between the ports is configured on-demand.

[0021] Step 3: data is received through a data transceiving module, and after the data is received, it is judged whether the other ports with the same line identifier have received the data, if the data has been received, the process is directly ended, otherwise, step 4 is entered.

[0022] Step 4: if the port is configured with a data processing program, the received data is processed through the data processing module, and then step 5 is entered, otherwise, step 6 is directly entered.

[0023] When the data processing module processes the data, the original data can be modified, and it can be selected whether the data needs to be transferred to the subsequent step.

[0024] Step 5: if the data needs to be distributed, step 6 is entered, otherwise, the process is directly ended.

[0025] Step 6: Distribute the data to the data subscription module of the corresponding port through the data distribution module.

[0026] Step 7: If the port is configured with a data processing program after subscribing to the data through the data subscription module, go to Step 8, otherwise go to Step 9.

[0027] Step 8: Process the subscribed data through the data processing module. If the data needs to be forwarded, go to Step 9, otherwise end directly.

[0028] When the data processing module processes the data, the original data can be modified, and it can be selected whether the data needs to be transferred to the subsequent step.

[0029] Step 9: Forward the data through the data sending module.

After receiving the data, go to Step 2; Step 2: Determine whether other ports with the same line identifier have received the same data. If yes, end directly, otherwise go to Step 3; Step 3: Determine whether a data processing program is configured. If yes, go to Step 4, otherwise go to Step 5; Step 4: Process the data through the data processing module. If the data is ignored, end directly, otherwise go to Step 5; Step 5: Push the data to other ports according to the subscription relationship through the data distribution module.

[0031] Reference Figure 3 A port subscription type data forwarding method for data transceiving and on-demand processing, the processing flow of the port subscribing data includes the following steps: Step 1: Subscribe to data through the data subscription module. After subscribing to the data, go to Step 2; Step 2: Determine whether a processing program is configured. If yes, go to Step 3, otherwise go to Step 4; Step 3: Process the data through the data processing module. If the data is ignored, end directly, otherwise go to Step 4; Step 4: Send the data through the data sending module.

[0032] Actual application scenario example I. Industrial Internet of Things monitoring system In the industrial Internet of Things monitoring system of a large factory, there are many different types of sensor devices, such as temperature sensors, pressure sensors, speed sensors, etc. These devices are distributed in various areas of the factory, and each sensor device can be regarded as a data sending port.

[0033] 1. Port setting and subscription relationship configuration First, according to the actual layout and monitoring requirements of the factory, multiple ports are added as needed, for example, a port is set for each main production equipment area in the workshop to receive data from sensor devices in that area. The communication method of the port is set to UDP unicast, because UDP unicast can accurately send data to a specified port, which is suitable for this point-to-point data transmission scenario. At the same time, a corresponding data processing program dynamic library file path is configured for each port, which can perform preliminary analysis and verification on sensor data, such as checking whether the temperature data is within a reasonable range. The data subscription relationship between ports is configured as needed, for example, the central monitoring room of the factory needs to receive data from all workshop ports, so the port corresponding to the central monitoring room subscribes to data from all workshop ports, while the control room of a specific workshop may only need to subscribe to data from some key sensor ports in that workshop.

[0034] 2. Data reception and processing When the sensor devices in the workshop send data through their corresponding ports, the ports receive the data through the data transceiver module. According to the line identifier, if other ports with the same line identifier have already received the same data (for example, the same group of sensor devices simultaneously sends the same data to multiple ports), then the processing is ended directly to avoid repeated processing. If the port is configured with a data processing program, the received data is processed through the data processing module, for example, after analyzing the temperature data, it is determined whether it exceeds the set threshold. If the data needs to be further notified to other ports (such as the central monitoring room port), the processed data is submitted to the data subscription module of the corresponding port through the data distribution module.

[0035] 3. Data subscription and forwarding After the central monitoring room port subscribes to the data from each workshop port through the data subscription module, if the data processing program is configured, the data is processed again, for example, all workshop temperature data is analyzed and summarized to determine the temperature distribution of the entire factory. If the processed data needs to be forwarded to other systems (such as the factory's management information system), the data is sent out through the data sending module to realize data sharing and further utilization.

[0036] II. Multimedia content distribution network (CDN) In a multimedia content distribution network, there are a large number of content server nodes, which need to obtain content from a source server and distribute the content to user terminals. Each content server node can be regarded as a port.

[0037] 1. Port setting and subscription relationship configuration New content server node ports are added on demand, and the communication mode of the ports is set to UDP multicast. Because multicast can efficiently send content to multiple subscribed nodes at the same time, it is suitable for large-scale distribution of multimedia content. A data processing program is configured for each port to perform preprocessing operations such as decoding and format conversion on received multimedia content. The data subscription relationship between ports is configured. For example, the content server port of the edge node subscribes to the content of the content server port of the center node to obtain the latest multimedia resources. At the same time, the port corresponding to the user terminal can also subscribe to the content of the edge node port.

[0038] 2. Data reception and processing When the center node content server port receives multimedia content data sent by the source server through the data transceiver module, the line identifier is used to avoid duplicate reception of the same content. The data processing module decodes and formats the received content to adapt to the needs of different user terminals. If the processed content needs to be distributed to the edge node port, the data distribution module submits the content to the data subscription module of the corresponding edge node port.

[0039] 3. Data subscription and forwarding After the edge node content server port subscribes to the content of the center node port through the data subscription module, the content is optimized by the data processing module, such as adjusting the code rate of the content according to the network status. If the processed content needs to be forwarded to the user terminal, the data sending module sends the content to the user terminal to achieve efficient distribution of multimedia content.

[0040] As can be seen from the above actual application scenarios, the port subscription type data forwarding method of the data transceiver on-demand processing of the present application can flexibly adapt to different network environments and business needs, and improve the efficiency of data transmission and processing.
