Description

Technical Field

[0001] This invention relates to the technical field of Internet data transmission, and in particular to a message queue remote sensing transmission method and system based on a data plane development kit. Background Technology

[0002] Currently, communication methods based on the Message Queuing Telemetry (MQTT) protocol all involve forwarding received data through the user's operating system to the corresponding user space for processing. This method relies on the user's operating system as an intermediary; when the user needs to receive large amounts of data, the operating system also needs to perform numerous data relay operations, increasing its workload. Furthermore, this method requires multiple data copying operations, inevitably leading to data tampering or loss during the copying process, reducing the security and reliability of data transmission. Therefore, existing MQTT-based communication methods suffer from high data transmission workload, susceptibility to data tampering, and high packet loss rates, failing to guarantee normal, fast, and secure data transmission. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a message queue remote sensing transmission method and system based on a data plane development kit. It generates a user-space protocol stack for the data plane development kit based on all user terminals with data receiving permissions on the Internet. Relevant data packets are captured from the gateway corresponding to the server, and based on the packet attribute information, the packets are directly sent to the user-space protocol stack to form a data packet queue. Based on the user terminal's data extraction request, the corresponding data packets are extracted from the data packet queue and sent directly to the user terminal that generated the data extraction request for processing according to the corresponding network path. By constructing a user-space protocol stack based on the user terminal's data plane development kit, it replaces the operating system as the intermediary for data transmission. In this way, data packets from the server are received and arranged into a data packet queue by the user-space protocol stack. Then, based on the user terminal's data extraction request, the appropriate data packets are extracted and sent, ensuring that the user terminal receives the required data packets in a timely and accurate manner. During data transmission, it does not impose a workload on the operating system. Furthermore, by using the user-space protocol stack as a data transmission relay medium, it eliminates the need for multiple data copies, avoiding data tampering or loss, thereby improving the security and reliability of data transmission.

[0004] This invention provides a message queue remote sensing transmission method based on a data plane development kit, comprising the following steps:

[0005] Step S1: Determine the data receiving permission of the user terminal based on the communication status information of the user terminal connected to the Internet; generate the corresponding data plane development kit user-mode protocol stack based on the user terminal with data receiving permission.

[0006] Step S2: Obtain the data transmission status information of the gateway corresponding to the server; capture the data packets transmitted by the gateway based on the data transmission status information; parse the data packets to obtain the attribute information corresponding to the data packets.

[0007] Step S3: Based on the attribute information, the data packet is directly sent to the user-space protocol stack to form a data packet queue; based on the data extraction request from the user terminal, the corresponding data packet is extracted from the data packet queue.

[0008] Step S4: According to the corresponding network path, the extracted data packet is directly sent to the user terminal that generated the data extraction request for processing.

[0009] Further, in step S1, the data receiving permission of the user terminal is determined based on the communication status information of the user terminal connected to the Internet; based on the user terminal with data receiving permission, a corresponding data plane development kit user-space protocol stack is generated, including:

[0010] The system obtains the real-time communication load status information of all user terminals connected to the Internet, and extracts the uplink data communication rate and downlink data communication rate of the user terminals from the real-time communication load status information. If the uplink data communication rate is greater than a first preset rate threshold or the downlink data communication rate is greater than a second preset rate threshold, it is determined that the corresponding user terminal does not have data receiving permission; otherwise, it is determined that the corresponding user terminal has data receiving permission.

[0011] For each user terminal with data receiving permissions, the data plane development kit protocol is loaded, generating a data plane development kit user-mode protocol middleware corresponding to each user terminal with data receiving permissions; then, according to the priority order of data receiving permissions of all user terminals with data receiving permissions from high to low, all data plane development kit user-mode protocol middleware are arranged to form a data plane development kit user-mode protocol stack.

[0012] Further, in step S2, the data transmission status information of the gateway corresponding to the server is obtained; based on the data transmission status information, data packets transmitted by the gateway are captured; the data packets are parsed to obtain the attribute information corresponding to the data packets, including:

[0013] Obtain the real-time data transmission volume value of the gateway corresponding to the server in the Internet. If the real-time data transmission volume value is greater than or equal to a preset data volume threshold, capture the data packets currently being transmitted by the gateway.

[0014] The data packet is parsed to obtain the identity information of the user terminal to which the data packet needs to be transmitted, and this information is used as the attribute information.

[0015] Further, in step S3, based on the attribute information, the data packet is directly sent to the user-space protocol stack to form a data packet queue; based on the data extraction request from the user terminal, the corresponding data packet is extracted from the data packet queue, including:

[0016] Based on the identity information, a matching user-mode protocol middleware is selected from the user-mode protocol stack, and the data packet is sent to the selected user-mode protocol middleware, thereby forming a data packet queue at the middleware of the user-mode protocol stack for all data packets captured from the gateway at different times.

[0017] Based on the identity information contained in the data extraction request from a user terminal with data receiving permissions, extract the data packet corresponding to the user-state protocol intermediate terminal that matches the identity information from the data packet queue.

[0018] Furthermore, in step S4, the extracted data packets are directly sent to the user terminal that generated the data extraction request for processing according to the corresponding network path, including:

[0019] According to the shortest network path in the Internet between the user-space protocol stack and the user terminal that generated the data extraction request, the extracted data packet is directly sent to the user terminal that generated the data extraction request for processing, and the processing result is returned to the corresponding user-space protocol intermediate terminal according to the original network path.

[0020] This invention also provides a message queue remote sensing transmission system based on a data plane development kit, comprising:

[0021] The user-mode protocol stack generation module is used to determine the data receiving permissions of the user terminal based on the communication status information of the user terminal connected to the Internet; and to generate the corresponding data plane development kit user-mode protocol stack based on the user terminal with data receiving permissions.

[0022] The data packet identification module is used to obtain the data transmission status information of the gateway corresponding to the server, capture the data packets transmitted by the gateway based on the data transmission status information, and parse the data packets to obtain the attribute information corresponding to the data packets.

[0023] The data packet extraction module is used to send the data packets directly to the user-space protocol stack according to the attribute information, thereby forming a data packet queue; and to extract the corresponding data packets from the data packet queue according to the data extraction request from the user terminal.

[0024] The data packet sending module is used to send the extracted data packets directly to the user terminal that generated the data extraction request for processing, according to the corresponding network path.

[0025] Furthermore, the user-space protocol stack generation module determines the data receiving permissions of the user terminal based on the communication status information of the user terminal connected to the Internet; and generates a corresponding data plane development kit user-space protocol stack based on the user terminal with data receiving permissions, including:

[0026] The system obtains the real-time communication load status information of all user terminals connected to the Internet, and extracts the uplink data communication rate and downlink data communication rate of the user terminals from the real-time communication load status information. If the uplink data communication rate is greater than a first preset rate threshold or the downlink data communication rate is greater than a second preset rate threshold, it is determined that the corresponding user terminal does not have data receiving permission; otherwise, it is determined that the corresponding user terminal has data receiving permission.

[0027] For each user terminal with data receiving permissions, the data plane development kit protocol is loaded, generating a data plane development kit user-mode protocol middleware corresponding to each user terminal with data receiving permissions; then, according to the priority order of data receiving permissions of all user terminals with data receiving permissions from high to low, all data plane development kit user-mode protocol middleware are arranged to form a data plane development kit user-mode protocol stack.

[0028] Furthermore, the data packet identification module obtains the data transmission status information of the gateway corresponding to the server, and captures the data packets transmitted by the gateway based on the data transmission status information; it then parses the data packets to obtain the attribute information corresponding to the data packets, including:

[0029] Obtain the real-time data transmission volume value of the gateway corresponding to the server in the Internet. If the real-time data transmission volume value is greater than or equal to a preset data volume threshold, capture the data packets currently being transmitted by the gateway.

[0030] The data packet is parsed to obtain the identity information of the user terminal to which the data packet needs to be transmitted, and this information is used as the attribute information.

[0031] Furthermore, the data packet extraction module directly sends the data packet to the user-space protocol stack based on the attribute information, thereby forming a data packet queue; according to the data extraction request from the user terminal, it extracts the corresponding data packet from the data packet queue, including:

[0032] Based on the identity information, a matching user-mode protocol middleware is selected from the user-mode protocol stack, and the data packet is sent to the selected user-mode protocol middleware, thereby forming a data packet queue at the middleware of the user-mode protocol stack for all data packets captured from the gateway at different times.

[0033] Based on the identity information contained in the data extraction request from a user terminal with data receiving permissions, extract the data packet corresponding to the user-state protocol intermediate terminal that matches the identity information from the data packet queue.

[0034] Furthermore, the data packet sending module sends the extracted data packets directly to the user terminal that generated the data extraction request for processing, according to the corresponding network path, including:

[0035] According to the shortest network path in the Internet between the user-space protocol stack and the user terminal that generated the data extraction request, the extracted data packet is directly sent to the user terminal that generated the data extraction request for processing, and the processing result is returned to the corresponding user-space protocol intermediate terminal according to the original network path.

[0036] Compared to existing technologies, this message queue remote sensing transmission method and system based on a data plane development kit generates a user-space protocol stack for the data plane development kit based on all user terminals with data receiving permissions on the Internet. It captures relevant data packets from the gateway corresponding to the server, and sends these packets directly to the user-space protocol stack according to their attribute information, forming a data packet queue. Based on the user terminal's data extraction request, it extracts the corresponding data packets from the data packet queue and sends them directly to the user terminal that generated the data extraction request for processing, following the appropriate network path. By constructing a user-space protocol stack for the user terminal's data plane development kit, it replaces the operating system as the intermediary for data transmission. In this way, data packets from the server are received and arranged into a data packet queue by the user-space protocol stack. Then, based on the user terminal's data extraction request, the appropriate data packets are extracted and sent, ensuring that the user terminal receives the required data packets in a timely and accurate manner. During data transmission, it does not impose a workload on the operating system. Furthermore, by using the user-space protocol stack as a data transmission relay medium, it eliminates the need for multiple data copies, preventing data tampering or loss, thereby improving the security and reliability of data transmission.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0043] See Figure 1 This is a flowchart illustrating a message queue remote sensing transmission method based on a data plane development kit provided in an embodiment of the present invention. The message queue remote sensing transmission method based on the data plane development kit includes the following steps:

[0044] Step S1: Determine the data receiving permission of the user terminal based on the communication status information of the user terminal connected to the Internet; generate the corresponding data plane development kit user-mode protocol stack based on the user terminal with data receiving permission.

[0045] Step S2: Obtain the data transmission status information of the gateway corresponding to the server; capture the data packets transmitted by the gateway based on the data transmission status information; parse the data packets to obtain the attribute information corresponding to the data packets.

[0046] Step S3: Based on the attribute information, the data packet is directly sent to the user-space protocol stack to form a data packet queue; based on the data extraction request from the user terminal, the corresponding data packet is extracted from the data packet queue.

[0047] Step S4: According to the corresponding network path, the extracted data packet is directly sent to the user terminal that generated the data extraction request for processing.

[0048] The beneficial effects of the above technical solution are as follows: This message queue remote sensing transmission method based on the data plane development kit generates a user-space protocol stack of the data plane development kit according to all user terminals with data receiving permissions on the Internet; it captures the corresponding data packets from the gateway corresponding to the server, and sends the data packets directly to the user-space protocol stack according to the attribute information of the data packets, forming a data packet queue; according to the data extraction request of the user terminal, it extracts the corresponding data packets from the data packet queue, and sends the extracted data packets directly to the user terminal that generated the data extraction request for processing according to the corresponding network path. By constructing a user-space protocol stack of the data plane development kit for the user terminal, it replaces the operating system as the medium for data transmission. In this way, data packets from the server are received and arranged by the user-space protocol stack to form a data packet queue, and then the appropriate data packets are extracted and sent according to the data extraction request of the user terminal, ensuring that the user terminal receives the required data packets in a timely and accurate manner. During the data transmission process, it does not cause a workload on the operating system. Furthermore, by using the user-space protocol stack as a data transmission relay medium, it is not necessary to copy the data multiple times, avoiding data tampering or data loss, thereby improving the security and reliability of data transmission.

[0049] Preferably, in step S1, the data receiving permission of the user terminal is determined based on the communication status information of the user terminal connected to the Internet; based on the user terminal with data receiving permission, a corresponding data plane development kit user-space protocol stack is generated, including:

[0050] Obtain the real-time communication load status information of all user terminals connected to the Internet, and extract the uplink data communication rate and downlink data communication rate of the user terminals from the real-time communication load status information; if the uplink data communication rate is greater than a first preset rate threshold or the downlink data communication rate is greater than a second preset rate threshold, then determine that the corresponding user terminal does not have data receiving permission; otherwise, determine that the corresponding user terminal has data receiving permission.

[0051] For each user terminal with data receiving permissions, the data plane development kit protocol is loaded, generating a data plane development kit user-mode protocol middleware corresponding to each user terminal with data receiving permissions; then, according to the priority order of data receiving permissions of all user terminals with data receiving permissions from high to low, all data plane development kit user-mode protocol middleware are arranged to form a data plane development kit user-mode protocol stack.

[0052] The beneficial effects of the above technical solution are as follows: The Internet connects servers and user terminals. The server, acting as a data source, provides data to user terminals such as personal computers, enabling corresponding computational tasks. Each user terminal, upon connecting to the Internet, performs uplink and downlink data communication transmissions. By monitoring the uplink and downlink data communication rates and real-time communication load status information of the user terminal, it is possible to determine whether the user terminal is currently in a data communication overload state. Specifically, when the uplink data communication rate exceeds a first preset rate threshold or the downlink data communication rate exceeds a second preset rate threshold, it indicates that the user terminal is currently in an uplink data transmission limit state or a downlink data transmission limit state, i.e., the user terminal is currently in a data communication overload state. At this time, the user terminal is prohibited from obtaining data receiving permissions associated with the server to avoid data congestion or crashes. When the user terminal is not currently in a data communication overload state, it is granted data receiving permissions associated with the server, ensuring normal data transmission between the user terminal and the server. Each user terminal with data receiving permissions loads the Data Plane Development Kit (DDP) protocol, generating a corresponding DDP user-mode protocol middleware. This middleware is a virtual server corresponding to a user terminal, compatible with the DDP, enabling accurate and secure management of received data packets. Furthermore, each user terminal with data receiving permissions is arranged in descending order of their internet data receiving permissions to form a DDP user-mode protocol stack. This ensures that each middleware receives data packets from the server in an orderly manner; the higher the user terminal's internet data receiving permissions, the earlier it receives data packets from the server.

[0053] Preferably, in step S2, the data transmission status information of the gateway corresponding to the server is obtained; based on the data transmission status information, the data packets transmitted by the gateway are captured; the data packets are parsed to obtain the attribute information corresponding to the data packets, including:

[0054] Get the real-time data transmission volume of the gateway connected to the server on the Internet. If the real-time data transmission volume is greater than or equal to the preset data volume threshold, capture the data packets currently being transmitted by the gateway.

[0055] The data packet is parsed to obtain the identity information of the user terminal to which the data packet needs to be transmitted, and this information is used as the attribute information.

[0056] The beneficial effects of the above technical solution are as follows: Real-time monitoring of the data transmission volume of the gateway to which the server is connected in the Internet enables timely and accurate capture of currently transmitted data packets from the gateway, avoiding missed data packet capture. Furthermore, each time the server sends a data packet, it adds the identity information of the user client to which it is intended. This data packet parsing process facilitates the accurate delivery of subsequently captured data packets to the corresponding user-space protocol middleware in the user-space protocol stack.

[0057] Preferably, in step S3, based on the attribute information, the data packet is directly sent to the user-space protocol stack to form a data packet queue; based on the data extraction request from the user terminal, the corresponding data packet is extracted from the data packet queue, including:

[0058] Based on the identity information, a matching user-mode protocol middleware is selected from the user-mode protocol stack, and the data packet is sent to the selected user-mode protocol middleware, thereby forming a data packet queue of all data packets captured from the gateway at different times in the user-mode protocol stack middleware.

[0059] Based on the identity information contained in the data extraction request from a user terminal with data receiving permissions, extract the data packet corresponding to the user-state protocol intermediate terminal that matches the identity information from the data packet queue.

[0060] The beneficial effects of the above technical solution are as follows: By using the parsed identity information as a starting point, a matching user-space protocol middleware is selected from the user-space protocol stack, and the extracted data packets are then sent to the selected user-space protocol middleware. This ensures that data packets captured from the gateway at different times are sent to the corresponding user-space protocol middleware, forming corresponding data packet queues, thus guaranteeing the correct and secure reception of data packets. Furthermore, based on the identity information contained in the data extraction request from a user terminal with data receiving permissions, data packets corresponding to the user-space protocol middleware matching the identity information are extracted from the data packet queue. This ensures that each data packet is accurately sent from the user-space protocol middleware to the corresponding user terminal, avoiding data packet mismatches.

[0061] Preferably, in step S4, the extracted data packets are directly sent to the user terminal that generated the data extraction request for processing according to the corresponding network path, including:

[0062] According to the shortest network path in the Internet between the user-space protocol stack and the user terminal that generated the data extraction request, the extracted data packet is directly sent to the user terminal that generated the data extraction request for processing, and the result of the processing is returned to the corresponding user-space protocol intermediate terminal according to the original network path.

[0063] The beneficial effects of the above technical solution are as follows: By using the above method, the data packet is sent to the corresponding user terminal based on the shortest network path in the Internet between the user-space protocol stack and the user terminal that generated the data extraction request. This can improve the data transmission efficiency and avoid data packet transmission errors in the Internet. In addition, the result obtained by the user terminal after processing the received data packet is returned to the corresponding user-space protocol intermediate terminal according to the original shortest network path, thereby realizing the targeted storage of the processing result, which facilitates the server to accurately extract the processing result.
