Embodiment First, a configuration example of an information communication system 100 according to an embodiment of the present invention will be described using 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 backend service 20.

  The device 1 is, for example, a wireless communication terminal or various sensors. 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. 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 the three edge servers 10. However, the number of the 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 reception unit 11, a condition determination unit 12, an embedding unit 13, and a transmission unit 14.

  The receiving unit 11 receives a message transmitted from the device 1. In addition, the reception 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 the received message meets a predetermined condition. The predetermined condition is a condition regarding, for example, the type of data included in the message and the data range. Specific examples include conditions such that the data type is temperature and the data value is 30 or more. Note that the predetermined condition may be settable.

  The condition determination unit 12 outputs the message to the embedding unit 13 when the received message matches a predetermined condition. In addition, the condition determination unit 12 outputs the message to the transmission unit 14 when the received message does not meet a predetermined condition.

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

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

  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.

  Next, a configuration example of the back-end service 20 will be described using 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 a configuration including the three components 23 A to 23 C. However, the number of the components 23 included in the back end service 20 is not limited to three.

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

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

  Each of the components 23A to 23C includes a different service logic 24. That is, the component 23A includes a service logic 24A, the component 23B includes a service logic 24B, and the component 23C includes a service logic 24C.

  A specific example in which the components 23A to 23C are components in the agricultural field such as a farm will be described. In this case, the service logic 24A is, for example, determination logic related to temperature data included in the message. The service logic 24B is determination logic related to humidity data included in the message, for example. The service logic 24C is determination logic related to carbon dioxide data included in the message, for example. For example, when the temperature data included in the message is equal to or higher than a predetermined temperature, the service logic 24A performs processing such as notifying a predetermined destination such as a user's wireless communication terminal. 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 the predetermined humidity. Further, the service logic 24C performs processing such as notifying a predetermined destination when the carbon dioxide data included 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. In addition, 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 self component to the trace collection server 26 using the trace output information. Specifically, the trace output unit 25 of the component 23A, when the trace output information is embedded in the message received from the routing unit 22, displays the trace including the message and the component ID of the component 23A on the trace collection server 26. Output to. Then, the component 23A outputs the message received from the routing unit 22 to the component 23B by the transfer path 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. Thus, 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.

  Next, a configuration example of the trace collection server 26 will be described using the block diagram of FIG. The trace collection server 26 includes a trace file 27.

  When acquiring the trace from the component 23, the trace collection server 26 writes the acquired trace in the trace file 27. Thus, 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. For this reason, by referring to the trace file 27, it is possible to grasp which component the predetermined message has passed and which component the predetermined message has reached.

  Next, a processing example of the edge server 10 will be described using the flowchart of FIG.

  First, the edge server 10 receives a 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).

  If 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 transmits 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 backend 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 backend service 20 (step S104).

  Next, a processing example of the component 23 will be described using the flowchart of FIG.

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

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

  Next, the component 23 determines whether or not 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 the component itself to the trace collection server 26 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 the condition determination unit 12 that determines whether or not the message transmitted from the device 1 matches a predetermined condition. The edge server 10 includes an embedding unit 13 that embeds trace output information in a message when the message matches a predetermined condition. Furthermore, 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 the trace output information in a message that matches a predetermined condition and transmit it to the back-end service 20. For this reason, the backend service 20 can output a 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, the edge server 10 can set a predetermined condition. As a result, the edge server 10 can set a desired condition as the predetermined condition, and can embed the trace output information in a message that matches the desired condition. That is, the back-end service 20 can output a trace related to a message that meets a desired condition.

  In addition, the component 23 according to the present embodiment determines whether or not the trace output information is embedded in the received message. If the trace output information is embedded, the component 23 uses the trace output information. The trace output unit 25 outputs the trace including the message and the component ID of the component itself to the trace collection server 26. 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 a message meets a predetermined condition only at the edge server 10 to which the target device 1 is connected. For this reason, in the information communication system 100, the influence on the performance by the output of the trace can be localized.

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

  In the above example, the program can be stored and supplied to a computer using various types of non-transitory computer readable media. Non-transitory computer readable media include various types of tangible storage media. Examples of non-transitory computer-readable media include magnetic recording media (for example, flexible disks, magnetic tapes, hard disk drives), magneto-optical recording media (for example, magneto-optical disks), CD-ROMs (Read Only Memory), CD-Rs, CD-R / W, semiconductor memory (for example, mask ROM, PROM (Programmable ROM), EPROM (Erasable PROM), flash ROM, RAM (Random Access Memory)) are included. The program may also be supplied to the computer by various types of transitory computer readable media. Examples of transitory computer readable media include electrical signals, optical signals, and electromagnetic waves. The temporary computer-readable medium can supply the program to the computer via a wired communication path such as an electric wire and an optical fiber, or a wireless communication path.
