[0024] For the convenience of description, some nouns or terms involved in the embodiments of the present application are explained below:

[0025] MQTT: Message Queuing Telemetry Transport, is a client-server based message publish / subscribe transport protocol.

[0026] As introduced in the background technology, the communication process based on the MQTT protocol in the prior art requires manual configuration and debugging, which is time-consuming and labor-intensive. In order to solve the problem that the communication process based on the MQTT protocol requires manual configuration and debugging, which is time-consuming and labor-intensive, the embodiments of the present application provide an MQTT service generation method, server and MQTT proxy server.

[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0028] In this embodiment, a method for generating an MQTT service running on a mobile terminal, a computer terminal or a similar computing device is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0029] Figure 1is a flow chart of the MQTT service generation method according to an embodiment of the present application. Figure 1 As shown, the method comprises the following steps:

[0030] Step S201, receiving a service application sent by a client, and determining whether the client is a target service object, wherein the service application is used to apply for access to an MQTT service, the target service object is an object of the MQTT service, and the MQTT service is a service that processes data on an MQTT proxy server;

[0031] Specifically, the present application constructs a proxy service system based on the MQTT protocol. MQTT (Message Queuing Telemetry Transport) is a client-server based message publish / subscribe transmission protocol. The system consists of an MQTT proxy server, a dedicated line generation service, a client (which can be a device end, a user end, etc.) and a database. The MQTT proxy server is responsible for receiving, processing and forwarding messages from the client, and the dedicated line generation service pre-configures the object-oriented information of the dedicated line generation service. The executor of this embodiment is a server, or a main server, which is used to monitor the resource configuration of the server cluster and configure the above-mentioned dedicated line generation service. The client generally logs in through a smart device, and the client sends a service application, which is first transmitted to the MQTT proxy server. The MQTT proxy server further sends the application to the server that configures the dedicated line generation service. The server determines whether the client is within the service object range. If it is within the service object range, it indicates that the client is the target service object.

[0032] Step S202, when the client is the target service object, obtain the resource usage rate of the server, determine the server whose resource usage rate is less than a preset threshold and is not configured with the MQTT replica service as the target server, and generate a target address of the target server, wherein the resource usage rate represents the usage status of the server resources, and the target address is the Internet Protocol address of the target server;

[0033] Specifically, when the client is within the service object range, the server monitors the resource usage of each server in the MQTT proxy server cluster in real time. The resource usage can include key resource indicators such as memory usage, CPU usage, and physical memory occupancy. When the resource usage is less than the preset threshold, it indicates that the server has less load and sufficient resources, which is suitable for configuring the MQTT service. It is also necessary to consider whether the MQTT service has been configured. Select server resources with sufficient resources and no MQTT service configured, obtain the target server, and provide the target server's target address (ID) and other service configurations. The service configuration mainly includes: 1. Dedicated service object ID; 2. Dedicated service IP group; 3. Dedicated service location range; 4. Service effective time.

[0034] Step S203: Generate a copy request according to the target address, and send the copy request to the MQTT proxy server, so that the MQTT proxy server generates an MQTT copy service corresponding to the target address and sends it to the target server, so that the target server processes data for the client based on the MQTT copy service, wherein the copy request is used to request the generation of the MQTT copy service, and the MQTT copy service is a copy of the MQTT service.

[0035] Specifically, a replica request is generated according to the above target address. In actual applications, a more specific replica request can also be generated according to the above four service configurations and sent to the MQTT proxy server. The MQTT proxy server generates an MQTT replica service and sends the generated result back to the server. The server executes the MQTT replica service (program) on the selected target server to generate a new MQTT proxy service instance, which will inherit the configuration and functions of the main MQTT proxy service and take over the connection and data processing tasks of the newly added device end for the configured service scope. The main MQTT proxy service is a service that is directly executed on the MQTT proxy server.

[0036] Through this embodiment, a service application sent by a client is received to determine whether the client is the target service object; when the client is the target service object, the resource utilization rate of the server is obtained, and a server whose resource utilization rate is less than a preset threshold and is not configured with an MQTT replica service is determined as a target server, and a target address of the target server is generated; a replica request is generated according to the target address, and the replica request is sent to the MQTT proxy server, so that the MQTT proxy server generates an MQTT replica service corresponding to the target address and sends it to the target server, so that the target server processes data for the client based on the MQTT replica service. Compared with the prior art, the communication process based on the MQTT protocol requires manual configuration and debugging, which is time-consuming, labor-intensive, cumbersome, and prone to errors. The present application automatically establishes an MQTT replica service through the above steps to process data based on the MQTT replica service on the target server, thereby eliminating the need for manual configuration and debugging. Therefore, it can solve the problem of the prior art that the communication process based on the MQTT protocol requires manual configuration and debugging, and achieves the effect of concise steps and reduced error rate.

[0037] In a specific implementation process, the above step S202 determines whether the client is the target service object, which can be implemented by the following steps: Step S2021: Acquire the Internet Protocol address and geographical location of the client; Step S2022: When the Internet Protocol address of the client is a preset address and the geographical location is a preset location, determine that the client is the target service object. The method determines whether the client is the target service object through the above steps, so that service configuration can be further performed for the client.

[0038] Specifically, the server's dedicated line generation service determines whether the IP (Internet Protocol address) and geographic location reported by the client are within the pre-configured object and scope allowed for the dedicated line service. If the Internet Protocol address is a preset address and the geographic location is a preset location, the client is determined to be the target service object.

[0039] In some optional implementations, the above step S202 obtains the resource usage of the server, and determines the server whose resource usage is less than a preset threshold and is not configured with an MQTT replica service as a target server, which can be achieved by the following steps: Step S2023: at least obtain the memory usage and processor usage of the server; Step S2024: when the memory usage is less than a preset memory threshold and the processor usage is less than a preset processor threshold and the server is not configured with an MQTT replica service, determine that the server is a target server. The method determines the target server through the above steps, so that qualified servers can be screened to smoothly configure the MQTT service.

[0040] In the specific implementation process, the resource pressure of the server is monitored to determine whether the resource utilization rate meets the requirements for configuring the MQTT service. The dedicated line service monitors the key resource indicators such as the memory utilization rate, CPU utilization rate, and physical memory utilization rate of each server in the MQTT proxy server cluster in real time. The server resource pressure level is as follows: 1. Low pressure level, memory utilization rate is less than 20%, CPU utilization rate is less than 20%, and physical memory utilization rate is less than 30%. In this state, the server runs smoothly, resources are sufficient, and more connections and message loads can be processed. The dedicated line service can be configured. 2. Medium pressure level, memory utilization rate is 20%-50%, CPU utilization rate is less than 20%-70%, and physical memory utilization rate is 30%-70%. The server begins to feel a certain load, but it is still capable of handling increased requests. After the dedicated line service is generated, it may be necessary to monitor the system performance. 3. High pressure level, memory utilization rate exceeds 50%, CPU utilization rate exceeds 70%, and physical memory utilization rate exceeds 70%. The server load is high, and the generation of the dedicated line service may affect the response time and stability of the service.

[0041] In some other optional implementations, after generating the target address, the method further comprises the following steps: generating a target port and a service area, wherein the target port represents the communication port of the target server, and the service area represents the geographical area served by the target server. The method generates the configuration port and region through the above steps, so that a specific port and region of the service configuration can be generated to provide dedicated line service to the client.

[0042] During the specific implementation process, the configuration elements also include the service scope, the target port, i.e. the fixed IP port, and the service area, i.e. the fixed area service.

[0043] Figure 2 FIG. 1 is a flowchart of another MQTT service generation method according to an embodiment of the present application. Figure 2 As shown, the method comprises the following steps:

[0044] Step S301, receiving a replica request sent by a target server, wherein the replica request is used to request generation of an MQTT replica service, the MQTT replica service is a replica of an MQTT service, and the MQTT service is a service performed on the MQTT proxy server;

[0045] Specifically, the present application constructs a proxy service system based on the MQTT protocol. MQTT (Message Queuing Telemetry Transport) is a client-server based message publish / subscribe transmission protocol. The system consists of an MQTT proxy server, a dedicated line generation service, a client (which can be a device end, a user end, etc.) and a database. The MQTT proxy server is responsible for receiving, processing and forwarding messages from the client, and the dedicated line generation service pre-configures the object-oriented information of the dedicated line generation service. The executor of this embodiment is the MQTT proxy server. The client generally logs in through a smart device. The client sends a service application, which is first transmitted to the MQTT proxy server. The MQTT proxy server further sends the application to the server that configures the dedicated line generation service. The server determines whether the client is within the service object range. If it is within the service object range, it indicates that the client is the target service object.

[0046] Step S302, generate an MQTT replica service corresponding to the target address and send it to the target server so that the target server processes data for the client based on the MQTT replica service. The target address is the Internet Protocol address of the target server, and the target server is a server whose resource utilization rate is less than a preset threshold and the MQTT replica service is not configured.

[0047] Specifically, when the client is within the service object scope, the server monitors the resource utilization of each server in the MQTT proxy server cluster in real time. The resource utilization may include key resource indicators such as memory utilization, CPU utilization, and physical memory occupancy. When the resource utilization is less than the preset threshold, it indicates that the server has a small load and sufficient resources, and is suitable for configuring the MQTT service. It is also necessary to consider whether the MQTT service has been configured.

[0048] The server generates a replica request according to the above target address. In actual applications, a more specific replica request can also be generated according to the above four service configurations and sent to the MQTT proxy server. The MQTT proxy server generates an MQTT replica service and sends the generated result back to the server. The server executes the MQTT replica service (program) on the selected target server and generates a new MQTT proxy service instance. The instance will inherit the configuration and functions of the main MQTT proxy service and take over the connection and data processing tasks of the newly added device end for the configured service scope. The main MQTT proxy service is a service that is directly executed on the MQTT proxy server.

[0049] The above step S302 of the present application can be implemented through the following steps: the target address is the Internet Protocol address of the target server generated after the target server is determined. The method determines the target address through the above steps, so that the client can be allowed to access and provide dedicated line service through the target address.

[0050] During the specific implementation process, select server resources with sufficient resources and no MQTT service configured, obtain the target server, and provide service configurations such as the target address (ID) of the target server. The service configuration mainly includes: 1. Dedicated service object ID; 2. Dedicated service IP group; 3. Dedicated service location range; 4. Service effective time.

[0051] The above method also includes other implementation steps, for example: before obtaining the resource usage rate of the server, obtaining the Internet Protocol address and geographical location of the client, and determining that the client is a target service object when the Internet Protocol address of the client is a preset address and the geographical location is a preset location. The method determines whether the client is within the service range through the above steps, so as to determine whether to continue to configure the MQTT service.

[0052] Specifically, the server's dedicated line generation service determines whether the IP (Internet Protocol address) and geographic location reported by the client are within the pre-configured object and scope allowed for the dedicated line service. If the Internet Protocol address is a preset address and the geographic location is a preset location, the client is determined to be the target service object.

[0053] In some embodiments, the above method may include the following steps: the resource utilization rate of the server is less than a preset threshold, which at least includes that the memory utilization rate of the server is less than a preset memory threshold and the processor utilization rate is less than a preset processor threshold. The method determines the resource utilization rate of the server through the above steps to determine the target server based on the resource utilization rate, ensuring that the target server has sufficient operating resources.

[0054] In the specific implementation process, the resource pressure of the server is monitored to determine whether the resource utilization rate meets the requirements for configuring the MQTT service. The dedicated line service monitors the key resource indicators such as the memory utilization rate, CPU utilization rate, and physical memory utilization rate of each server in the MQTT proxy server cluster in real time. The server resource pressure level is as follows: 1. Low pressure level, memory utilization rate is less than 20%, CPU utilization rate is less than 20%, and physical memory utilization rate is less than 30%. In this state, the server runs smoothly, resources are sufficient, and more connections and message loads can be processed. The dedicated line service can be configured. 2. Medium pressure level, memory utilization rate is 20%-50%, CPU utilization rate is less than 20%-70%, and physical memory utilization rate is 30%-70%. The server begins to feel a certain load, but it is still capable of handling increased requests. After the dedicated line service is generated, it may be necessary to monitor the system performance. 3. High pressure level, memory utilization rate exceeds 50%, CPU utilization rate exceeds 70%, and physical memory utilization rate exceeds 70%. The server load is high, and the generation of the dedicated line service may affect the response time and stability of the service. The final configuration elements also include the service scope, the target port, i.e. the fixed IP port, and the service area, i.e. the fixed area service.

[0055] In order to enable those skilled in the art to more clearly understand the technical solution of the present application, the implementation process of the MQTT service generation method of the present application will be described in detail below in combination with specific embodiments.

[0056] This embodiment relates to a specific MQTT service generation method, such as Figure 3 As shown, it includes a smart device (client), an MQTT agent (server), and a dedicated line server (server), and includes the following steps:

[0057] Step S1: The smart device initiates an application to the MQTT proxy server for a dedicated line service;

[0058] Step S2: The MQTT proxy server applies for dedicated line service scheduling and initiates an application to the dedicated line server (server);

[0059] Step S3: The dedicated line server (device) applies for dedicated line service scheduling;

[0060] Step S4: Determine whether it is within the service object range;

[0061] Step S5: If yes, analyze the service resources of the MQTT proxy cluster server and whether there is a configured MQTT service, and request a server with sufficient resources and no configured MQTT service as the target server;

[0062] Step S6: providing the target address generated by the service, requesting to generate a copy of the MQTT proxy service corresponding to the dedicated line service, and requesting to generate a copy of the MQTT service from the MQTT proxy server;

[0063] Step S7: The MQTT proxy server generates an MQTT proxy replica service and automatically starts it;

[0064] Step S8: Provide the MQTT proxy service replica address and port, and notify the dedicated server of the generation result;

[0065] Step S9: The smart device sends an access request to apply for access to the MQTT proxy service replica service.

[0066] The embodiment of the present application also provides a server. It should be noted that the server of the embodiment of the present application can be used to execute the MQTT service generation method provided by the embodiment of the present application. The device is used to implement the above-mentioned embodiments and preferred implementation modes, and the descriptions have been omitted. As used below, the term "module" can implement a combination of software and / or hardware for a predetermined function. Although the device described in the following embodiments is preferably implemented in software, the implementation of hardware, or a combination of software and hardware, is also possible and conceived.

[0067] The following is an introduction to the server provided in the embodiment of the present application.

[0068] Figure 4 is a schematic diagram of a server according to an embodiment of the present application. Figure 4 As shown, the device comprises:

[0069] A determination unit 10 is used to receive a service application sent by a client, and determine whether the client is a target service object, wherein the service application is used to apply for access to an MQTT service, the target service object is an object of the MQTT service, and the MQTT service is a service that performs data processing on an MQTT proxy server;

[0070] Specifically, the present application constructs a proxy service system based on the MQTT protocol. MQTT (Message Queuing Telemetry Transport) is a client-server based message publish / subscribe transmission protocol. The system consists of an MQTT proxy server, a dedicated line generation service, a client (which can be a device end, a user end, etc.) and a database. The MQTT proxy server is responsible for receiving, processing and forwarding messages from the client, and the dedicated line generation service pre-configures the object-oriented information of the dedicated line generation service. The executor of this embodiment is a server, or a main server, which is used to monitor the resource configuration of the server cluster and configure the above-mentioned dedicated line generation service. The client generally logs in through a smart device, and the client sends a service application, which is first transmitted to the MQTT proxy server. The MQTT proxy server further sends the application to the server that configures the dedicated line generation service. The server determines whether the client is within the service object range. If it is within the service object range, it indicates that the client is the target service object.

[0071] A generating unit 20 is used to obtain a resource usage rate of a server when the client is the target service object, determine the server whose resource usage rate is less than a preset threshold and is not configured with the MQTT replica service as a target server, and generate a target address of the target server, wherein the resource usage rate indicates a usage status of server resources, and the target address is an Internet Protocol address of the target server;

[0072] Specifically, when the client is within the service object range, the server monitors the resource usage of each server in the MQTT proxy server cluster in real time. The resource usage can include key resource indicators such as memory usage, CPU usage, and physical memory occupancy. When the resource usage is less than the preset threshold, it indicates that the server has less load and sufficient resources, which is suitable for configuring the MQTT service. It is also necessary to consider whether the MQTT service has been configured. Select server resources with sufficient resources and no MQTT service configured, obtain the target server, and provide the target server's target address (ID) and other service configurations. The service configuration mainly includes: 1. Dedicated service object ID; 2. Dedicated service IP group; 3. Dedicated service location range; 4. Service effective time.

[0073] The first sending unit 30 is used to generate a copy request according to the target address, and send the copy request to the MQTT proxy server, so that the MQTT proxy server generates an MQTT copy service corresponding to the target address and sends it to the target server, so that the target server processes data for the client based on the MQTT copy service, wherein the copy request is used to request the generation of the MQTT copy service, and the MQTT copy service is a copy of the MQTT service.

[0074] Specifically, a replica request is generated according to the above target address. In actual applications, a more specific replica request can also be generated according to the above four service configurations and sent to the MQTT proxy server. The MQTT proxy server generates an MQTT replica service and sends the generated result back to the server. The server executes the MQTT replica service (program) on the selected target server to generate a new MQTT proxy service instance, which will inherit the configuration and functions of the main MQTT proxy service and take over the connection and data processing tasks of the newly added device end for the configured service scope. The main MQTT proxy service is a service that is directly executed on the MQTT proxy server.

[0075] Through this embodiment, a service application sent by a client is received to determine whether the client is the target service object; when the client is the target service object, the resource utilization rate of the server is obtained, and a server whose resource utilization rate is less than a preset threshold and is not configured with an MQTT replica service is determined as a target server, and a target address of the target server is generated; a replica request is generated according to the target address, and the replica request is sent to the MQTT proxy server, so that the MQTT proxy server generates an MQTT replica service corresponding to the target address and sends it to the target server, so that the target server processes data for the client based on the MQTT replica service. Compared with the prior art, the communication process based on the MQTT protocol requires manual configuration and debugging, which is time-consuming, labor-intensive, cumbersome, and prone to errors. The present application automatically establishes an MQTT replica service through the above steps to process data based on the MQTT replica service on the target server, thereby eliminating the need for manual configuration and debugging. Therefore, it can solve the problem of the prior art that the communication process based on the MQTT protocol requires manual configuration and debugging, and achieves the effect of concise steps and reduced error rate.

[0076] In a specific implementation process, the generation unit includes a first acquisition module and a first determination module, wherein the first acquisition module is used to acquire the Internet Protocol address and geographic location of the client; the first determination module is used to determine that the client is the target service object when the Internet Protocol address of the client is a preset address and the geographic location is a preset location. The method determines whether the client is the target service object through the above steps, so that service configuration can be further performed for the client.

[0077] Specifically, the server's dedicated line generation service determines whether the IP (Internet Protocol address) and geographic location reported by the client are within the pre-configured object and scope allowed for the dedicated line service. If the Internet Protocol address is a preset address and the geographic location is a preset location, the client is determined to be the target service object.

[0078] In some optional implementations, the generation unit further includes a second acquisition module and a second determination module, the second acquisition module is used to obtain at least the memory usage and processor usage of the server; the second determination module is used to determine that the server is a target server when the memory usage is less than a preset memory threshold and the processor usage is less than a preset processor threshold and the server is not configured with an MQTT replica service. The method determines the target server through the above steps, so that qualified servers can be screened to smoothly configure the MQTT service.

[0079] In the specific implementation process, the resource pressure of the server is monitored to determine whether the resource utilization rate meets the requirements for configuring the MQTT service. The dedicated line service monitors the key resource indicators such as the memory utilization rate, CPU utilization rate, and physical memory utilization rate of each server in the MQTT proxy server cluster in real time. The server resource pressure level is as follows: 1. Low pressure level, memory utilization rate is less than 20%, CPU utilization rate is less than 20%, and physical memory utilization rate is less than 30%. In this state, the server runs smoothly, resources are sufficient, and more connections and message loads can be processed. The dedicated line service can be configured. 2. Medium pressure level, memory utilization rate is 20%-50%, CPU utilization rate is less than 20%-70%, and physical memory utilization rate is 30%-70%. The server begins to feel a certain load, but it is still capable of handling increased requests. After the dedicated line service is generated, it may be necessary to monitor the system performance. 3. High pressure level, memory utilization rate exceeds 50%, CPU utilization rate exceeds 70%, and physical memory utilization rate exceeds 70%. The server load is high, and the generation of the dedicated line service may affect the response time and stability of the service.

[0080] In some other optional implementations, after generating the target address, the server further includes a generation unit for generating a target port and a service area, wherein the target port represents the communication port of the target server, and the service area represents the geographical area served by the target server. The method generates the configuration port and region through the above steps, so that a specific port and region of the service configuration can be generated to provide dedicated line service to the client.

[0081] During the specific implementation process, the configuration elements also include the service scope, the target port, i.e. the fixed IP port, and the service area, i.e. the fixed area service.

[0082] The server includes a processor and a memory, and the above-mentioned determination unit, generation unit and first sending unit are all stored in the memory as program units, and the processor executes the above-mentioned program units stored in the memory to realize corresponding functions. The above-mentioned modules are all located in the same processor; or, the above-mentioned modules are respectively located in different processors in the form of any combination.

[0083] The processor includes a kernel, which retrieves the corresponding program unit from the memory. One or more kernels can be set, and the kernel parameters can be adjusted to solve the problem that the communication process based on the MQTT protocol in the prior art needs to be manually configured and debugged, which is time-consuming and labor-intensive.

[0084] The memory may include non-permanent memory in a computer-readable medium, random access memory (RAM) and / or non-volatile memory, such as read-only memory (ROM) or flash RAM, and the memory includes at least one memory chip.

[0085] The embodiment of the present application also provides an MQTT proxy server. It should be noted that the MQTT proxy server of the embodiment of the present application can be used to execute the MQTT service generation method provided by the embodiment of the present application. The device is used to implement the above-mentioned embodiments and preferred implementation modes, and the descriptions have been omitted. As used below, the term "module" can implement a combination of software and / or hardware for a predetermined function. Although the device described in the following embodiments is preferably implemented in software, the implementation of hardware, or a combination of software and hardware, is also possible and conceived.

[0086] The following is an introduction to the MQTT proxy server provided in an embodiment of the present application.

[0087] Figure 5 is a schematic diagram of a server according to an embodiment of the present application. Figure 5 As shown, the device comprises:

[0088] The receiving unit 40 is used to receive a replica request sent by a target server, wherein the replica request is used to request the generation of an MQTT replica service, the MQTT replica service is a replica of the MQTT service, and the MQTT service is a service performed on the MQTT proxy server;

[0089] Specifically, the present application constructs a proxy service system based on the MQTT protocol. MQTT (Message Queuing Telemetry Transport) is a client-server based message publish / subscribe transmission protocol. The system consists of an MQTT proxy server, a dedicated line generation service, a client (which can be a device end, a user end, etc.) and a database. The MQTT proxy server is responsible for receiving, processing and forwarding messages from the client, and the dedicated line generation service pre-configures the object-oriented information of the dedicated line generation service. The executor of this embodiment is the MQTT proxy server. The client generally logs in through a smart device. The client sends a service application, which is first transmitted to the MQTT proxy server. The MQTT proxy server further sends the application to the server that configures the dedicated line generation service. The server determines whether the client is within the service object range. If it is within the service object range, it indicates that the client is the target service object.

[0090] The second sending unit 50 is used to generate an MQTT replica service corresponding to the target address and send it to the target server so that the target server can process data for the client based on the MQTT replica service. The target address is the Internet Protocol address of the target server, and the target server is a server whose resource utilization rate is less than a preset threshold and the MQTT replica service is not configured.

[0091] Specifically, when the client is within the service object scope, the server monitors the resource utilization of each server in the MQTT proxy server cluster in real time. The resource utilization may include key resource indicators such as memory utilization, CPU utilization, and physical memory occupancy. When the resource utilization is less than the preset threshold, it indicates that the server has a small load and sufficient resources, and is suitable for configuring the MQTT service. It is also necessary to consider whether the MQTT service has been configured.

[0092] The server generates a replica request according to the above target address. In actual applications, a more specific replica request can also be generated according to the above four service configurations and sent to the MQTT proxy server. The MQTT proxy server generates an MQTT replica service and sends the generated result back to the server. The server executes the MQTT replica service (program) on the selected target server and generates a new MQTT proxy service instance. The instance will inherit the configuration and functions of the main MQTT proxy service and take over the connection and data processing tasks of the newly added device end for the configured service scope. The main MQTT proxy service is a service that is directly executed on the MQTT proxy server.

[0093] The target address of the present application is the Internet Protocol address of the target server generated after the target server is determined. The method determines the target address through the above steps, so that the client can be allowed to access and perform dedicated line services through the target address.

[0094] During the specific implementation process, select server resources with sufficient resources and no MQTT service configured, obtain the target server, and provide service configurations such as the target address (ID) of the target server. The service configuration mainly includes: 1. Dedicated service object ID; 2. Dedicated service IP group; 3. Dedicated service location range; 4. Service effective time.

[0095] Before obtaining the resource usage rate of the server, the Internet Protocol address and geographic location of the client are obtained, and when the Internet Protocol address of the client is a preset address and the geographic location is a preset location, the client is determined to be a target service object. The method determines whether the client is within the service range through the above steps, so as to determine whether to continue to configure the MQTT service.

[0096] Specifically, the server's dedicated line generation service determines whether the IP (Internet Protocol address) and geographic location reported by the client are within the pre-configured object and scope allowed for the dedicated line service. If the Internet Protocol address is a preset address and the geographic location is a preset location, the client is determined to be the target service object.

[0097] In some embodiments, the resource utilization rate of the server described above being less than a preset threshold at least includes the memory utilization rate of the server being less than a preset memory threshold and the processor utilization rate being less than a preset processor threshold. The method determines the resource utilization rate of the server through the above steps to determine the target server based on the resource utilization rate, thereby ensuring that the target server has sufficient operating resources.

[0098] In the specific implementation process, the resource pressure of the server is monitored to determine whether the resource utilization rate meets the requirements for configuring the MQTT service. The dedicated line service monitors the key resource indicators such as the memory utilization rate, CPU utilization rate, and physical memory utilization rate of each server in the MQTT proxy server cluster in real time. The server resource pressure level is as follows: 1. Low pressure level, memory utilization rate is less than 20%, CPU utilization rate is less than 20%, and physical memory utilization rate is less than 30%. In this state, the server runs smoothly, resources are sufficient, and more connections and message loads can be processed. The dedicated line service can be configured. 2. Medium pressure level, memory utilization rate is 20%-50%, CPU utilization rate is less than 20%-70%, and physical memory utilization rate is 30%-70%. The server begins to feel a certain load, but it is still capable of handling increased requests. After the dedicated line service is generated, it may be necessary to monitor the system performance. 3. High pressure level, memory utilization rate exceeds 50%, CPU utilization rate exceeds 70%, and physical memory utilization rate exceeds 70%. The server load is high, and the generation of the dedicated line service may affect the response time and stability of the service. The final configuration elements also include the service scope, the target port, i.e. the fixed IP port, and the service area, i.e. the fixed area service.

The client generally logs in through a smart device, and the client sends a service application, which is first transmitted to the MQTT proxy server. The MQTT proxy server further sends the application to the server that configures the dedicated line generation service. The server determines whether the client is within the service object range.

It is also necessary to consider whether the MQTT service has been configured. Select server resources with sufficient resources and no MQTT service configured, obtain the target server, and provide the target server's target address (ID) and other service configurations. The service configuration mainly includes: 1. Dedicated service object ID; 2. Dedicated service IP group; 3. Dedicated service location range; 4. Service effective time.

[0106] Specifically, a replica request is generated according to the above target address. In actual applications, a more specific replica request can also be generated according to the above four service configurations and sent to the MQTT proxy server. The MQTT proxy server generates an MQTT replica service and sends the generated result back to the server. The server executes the MQTT replica service (program) on the selected target server to generate a new MQTT proxy service instance, which will inherit the configuration and functions of the main MQTT proxy service and take over the connection and data processing tasks of the newly added device end for the configured service scope. The main MQTT proxy service is a service that is directly executed on the MQTT proxy server.
