Embodiment First, a configuration example of the information communication system 100 according to the embodiment of the present invention will be described with reference to the block diagram of FIG. The information communication system 100 according to the present embodiment includes a device 1, an edge network 2, an edge server 10, a wide area network 3, and a back-end service 20.

The device 1 is, for example, a wireless communication terminal, various sensors, and the like. In the example of FIG. 1, three devices 1 are shown, but the number of devices 1 is not limited to three.

Device 1 generates a message. Further, the device 1 transmits the generated message to the edge server 10 connected via the edge network 2. That is, the device 1 transmits a message to one edge server 10 to which the device 1 is connected among the plurality of edge servers 10.

The edge network 2 is a network that connects the device 1 and the edge server 10. In the example of FIG. 1, the information communication system 100 includes three edge servers 10, but the number of edge servers 10 included in the information communication system 100 is not limited to three.

Here, a configuration example of the edge server 10 will be described with reference to the block diagram of FIG. The edge server 10 includes a receiving unit 11, a condition determining unit 12, an embedding unit 13, and a transmitting unit 14.

The receiving unit 11 receives the message transmitted from the device 1. Further, the receiving unit 11 outputs the received message to the condition determination unit 12.

The condition determination unit 12 receives a message from the reception unit 11. In addition, the condition determination unit 12 determines whether or not the received message meets a predetermined condition. The predetermined condition is, for example, a condition regarding the type of data included in the message, the range of data, and the like. Specific examples include conditions such as the type of data being temperature and the value of data being 30 or more. The predetermined conditions may be settable.

When the received message matches a predetermined condition, the condition determination unit 12 outputs the message to the embedding unit 13. If the received message does not meet a predetermined condition, the condition determination unit 12 outputs the message to the transmission unit 14.

The embedding unit 13 receives a message from the condition determination unit 12. Further, the embedding unit 13 embeds trace output information in the received message. That is, when the received message meets a predetermined condition, the embedding unit 13 embeds the trace output information in the message. The trace output information is, for example, information indicating a trace output destination such as a URL (Uniform Resource Locator) of a trace collection server in the back-end service 20, but is not limited to this. The trace output information may be any information as long as it enables the back-end service 20 to output a trace. Then, the embedding unit 13 outputs a message in which the trace output information is embedded to the transmitting unit 14.

The transmission unit 14 transmits the received message to the back-end service 20. That is, when the transmission unit 14 receives the message from the condition determination unit 12, the transmission unit 14 transmits the message in which the trace output information is not embedded to the back-end service 20. When the transmission unit 14 receives the message from the embedding unit 13, the transmission unit 14 transmits the message in which the trace output information is embedded to the back-end service 20.

The explanation will be continued by returning to FIG. The wide area network 3 is a network that connects the edge server 10 and the back-end service 20. The message transmitted by the transmission unit 14 of the edge server 10 is received by the back-end service 20 via the wide area network 3.

Subsequently, a configuration example of the back-end service 20 will be described with reference to the block diagram of FIG. The back-end service 20 includes a receiving unit 21, a routing unit 22, a component 23A, a component 23B, a component 23C, and a trace collection server 26. In the example of FIG. 3, the back-end service 20 includes the three components 23 of the components 23A to 23C, but the number of the components 23 included in the back-end service 20 is not limited to three.

The receiving unit 21 receives the message transmitted from the transmitting unit 14 of the edge server 10. Further, the receiving unit 21 outputs the received message to the routing unit 22.

The routing unit 22 receives a message from the receiving unit 21. In addition, the routing unit 22 controls the transfer route of the received message. Specifically, the routing unit 22 controls which component 23 and in what order the received message is transferred. For example, the routing unit 22 includes routing information and controls a forwarding route based on the routing information. Hereinafter, an example in which messages are transferred in the order of component 23A, component 23B, and component 23C will be described. The routing unit 22 outputs a message to the component 23A.

Here, a configuration example of the component 23 will be described with reference to the block diagram of FIG. The component 23 includes a service logic 24 and a trace output unit 25.

The components 23A to 23C have different service logics 24. That is, the component 23A includes the service logic 24A, the component 23B includes the service logic 24B, and the component 23C includes the service logic 24C.

Specific examples in which the components 23A to 23C are components for the agricultural field such as a farm will be described. In this case, the service logic 24A is, for example, a determination logic regarding the temperature data included in the message. Further, the service logic 24B is, for example, a determination logic regarding humidity data included in the message. Further, the service logic 24C is, for example, a determination logic regarding carbon dioxide data included in the message. For example, the service logic 24A performs processing such as notifying a predetermined destination such as a wireless communication terminal of a user when the temperature data included in the message is equal to or higher than a predetermined temperature. Further, the service logic 24B performs processing such as notifying a predetermined destination when the humidity data included in the message is equal to or higher than a predetermined humidity. Further, the service logic 24C performs processing such as notifying a predetermined destination when the carbon dioxide data contained in the message is equal to or higher than a predetermined carbon dioxide concentration.

The trace output unit 25 determines whether or not the trace output information is embedded in the received message. Further, when the trace output information is embedded in the message, the trace output unit 25 outputs the trace including the message and the component ID of the own component to the trace collection server 26 by using the trace output information. Specifically, when the trace output information is embedded in the message received from the routing unit 22, the trace output unit 25 of the component 23A collects the trace including the message and the component ID of the component 23A. Output to. Then, the component 23A outputs the message received from the routing unit 22 to the component 23B by the transfer route control by the routing unit 22. If the trace output information is not embedded in the message, the component 23A outputs the message received from the routing unit 22 to the component 23B without outputting the trace.

The trace output unit 25 of the component 23B and the component 23C performs the same processing as the trace output unit 25 of the component 23A. As a result, when the trace output information is embedded in the message, the message and the component IDs of the components 23A to 23C are output to the trace collection server 26 in the order of the component 23A, the component 23B, and the component 23C.

Subsequently, a configuration example of the trace collection server 26 will be described with reference to the block diagram of FIG. The trace collection server 26 includes a trace file 27.

When the trace collection server 26 acquires a trace from the component 23, the trace collection server 26 writes the acquired trace to the trace file 27. As a result, when the trace output information is embedded in the message, the message and the component IDs of the components 23A to 23C are written in the trace file 27 in the order of the component 23A, the component 23B, and the component 23C. Therefore, by referring to the trace file 27, it is possible to grasp which component the predetermined message has passed through and which component the predetermined message has reached.

Subsequently, a processing example of the edge server 10 will be described with reference to the flowchart of FIG.

First, the edge server 10 receives the message transmitted from the device 1 (step S101).

Next, the edge server 10 determines whether or not the received message meets a predetermined condition (step S102).

When the received message matches a predetermined condition (YES in step S102), the edge server 10 embeds the trace output information in the message (step S103). Next, the edge server 10 sends a message to the backend service 20 (step S104). That is, the edge server 10 transmits a message in which the trace output information is embedded to the back-end service 20.

On the other hand, if the received message does not meet the predetermined condition (NO in step S102), the process proceeds to step S104 without going through step S103. That is, when the received message does not meet the predetermined condition (NO in step S102), the edge server 10 transmits a message in which the trace output information is not embedded to the back-end service 20 (step S104).

Subsequently, a processing example of the component 23 will be described with reference to the flowchart of FIG.

First, the component 23 receives the message transmitted from the edge server 10 (step S201).

Next, the component 23 executes a process based on the service logic included in the own component (step S202).

Next, the component 23 determines whether or not the trace output information is embedded in the message (step S203).

When the trace output information is embedded in the message (YES in step S203), the component 23 outputs the trace including the message and the component ID of its own component to the trace collection server 26 by using the trace output information. (Step S204).

On the other hand, when the trace output information is not embedded in the message (NO in step S203), the component 23 ends without outputting the trace to the trace collection server 26.

As described above, the edge server 10 according to the embodiment of the present invention is configured to include a condition determination unit 12 for determining whether or not the message transmitted from the device 1 meets a predetermined condition. Further, the edge server 10 is configured to include an embedding unit 13 for embedding trace output information in the message when the message meets a predetermined condition. Further, the edge server 10 is configured to include a transmission unit 14 that transmits a message to the back-end service 20. As a result, the edge server 10 according to the present embodiment can embed trace output information in a message that matches a predetermined condition and transmit it to the back-end service 20. Therefore, the back-end service 20 can output the trace only for the message in which the trace output information is embedded. That is, it is possible to efficiently output a trace related to a message.

Further, in the edge server 10, a predetermined condition can be set. As a result, in the edge server 10, a desired condition can be set as a predetermined condition, and trace output information can be embedded in a message that matches the desired condition. That is, the back-end service 20 can output a trace related to a message that matches a desired condition.

Further, the component 23 according to the present embodiment determines whether or not the trace output information is embedded in the received message, and when the trace output information is embedded, the component 23 uses the trace output information. , A trace output unit 25 that outputs a trace including a message and a component ID of its own component to the trace collection server 26 is provided. As a result, the back-end service 20 can use a simple determination as to whether or not the trace output information is embedded in the message as the determination for outputting the trace. That is, it is possible to efficiently output a trace related to a message.

Further, in the information communication system 100 according to the present embodiment, it is possible to determine whether or not the message satisfies a predetermined condition only on the edge server 10 to which the target device 1 is connected. Therefore, in the information communication system 100, the influence of the trace output on the performance can be localized.

The processing performed by the edge server 10 and the back-end service 20 described in the above-described embodiment is the ASIC (Application Specific Integrated Circuit), DSP (Digital Signal Processor), and MPU (Micro) included in the edge server 10 and the back-end service 20. It can be realized by using a computer system including a processing unit or a CPU (Central Processing Unit) or a combination thereof. Specifically, the computer system may execute a program including a group of instructions related to the processing of each functional unit in the edge server 10 and the back-end service 20 described using the block diagram or the flowchart.
