In addition, this invention is not limited by this embodiment.

[First embodiment]
First, the outline of the system according to the first embodiment will be described with reference to FIG. FIG. 1 is a block diagram showing a configuration of a system according to the present embodiment. As shown in the figure, the system according to this embodiment includes a lookup server 10, a client terminal 20, and a server 30. Further, the lookup server 10, the client terminal 20, and the server 30 are connected via the network 40. Here, the network 40 is, for example, 3G (3rd Generation), LTE (Long Term Evolution), WiFi (Wireless Fidelity), or the like. Communication in the lookup server 10, the client terminal 20, and the server 30 is not limited to wireless communication, and may be wired communication. Moreover, although the example of FIG. 1 illustrates the case where each device exists one by one, it is not limited to this, and a plurality of each device may exist.

  In the following description, a system in which the client terminal 20 executes an application in cooperation with the server 30 having a distributed execution environment will be described, but this system is not limited to such an embodiment. For example, a system that executes an application in cooperation between the client terminals 20 or between the servers 30 may be used. In this system, the types of execution environments such as the client terminal 20 and the server 30 and the types of applications to be executed may be the same.

  The lookup server 10 receives from the client terminal 20 policy information that is information related to the execution environment of the application designated by the user of the client terminal 20. Then, the lookup server 10 selects the server 30 that executes processing related to the application in accordance with the received policy information. Then, the lookup server 10 controls to connect the selected server 30 and the client terminal 20.

  The client terminal 20 is an information processing apparatus that executes various applications. The client terminal 20 executes an application in cooperation with the server 30. For example, the client terminal 20 is connected to the Internet, such as a mobile phone, a PHS (Personal Handyphone System), a PDA (Personal Digital Assistant), a tablet PC (Personal Computer), etc., and communicates information with the server 30 and other client terminals. Any device can be used as long as it can transmit and receive. The client terminal 20 is not limited to a mobile terminal, and a computer installed in a home or office may be used.

  The server 30 executes arithmetic processing related to the application in the client terminal 20 and transmits the execution result to the client terminal 20. In the example of FIG. 1, it is assumed that the server 30 uses any one of thermal power + solar power generation, geothermal power generation, or nuclear power generation as a power source.

[Lookup server configuration]
Next, the configuration of the lookup server 10 will be described with reference to FIG. FIG. 2 is a block diagram showing the configuration of the lookup server according to the first embodiment. As illustrated in FIG. 2, the lookup server 10 includes a communication processing unit 11, a control unit 12, and a storage unit 13.

  The communication processing unit 11 controls communication related to various types of information exchanged with the connected client terminal 20, the server 30, and the like. For example, the communication processing unit 11 receives policy information from the client terminal 20, and transmits an ID that can uniquely identify the client terminal 20 and an IP address of the connection destination server 30 to the client terminal 20. In addition, the communication processing unit 11 transmits an operation check request and an instance generation request to the server 30, and receives an operation check result and an instance generation result from the server 30.

  As shown in FIG. 2, the storage unit 13 includes a policy information storage unit 13a and a server resource information storage unit 13b. The storage unit 13 is, for example, a semiconductor memory device such as a RAM (Random Access Memory) or a flash memory, or a storage device such as a hard disk or an optical disk.

  The policy information storage unit 13a stores policy information related to the execution environment of the application designated by the user of the client terminal 20. The policy information stored in the policy information storage unit 13a is information received from the client terminal 20 by the receiving unit 12a described later.

  For example, as illustrated in FIG. 3, the policy information storage unit 13 a specifies “regeneration energy” for the “terminal ID” that uniquely identifies the client terminal 20 and the energy used by the server 30 that executes the process related to the application. “Energy” indicating whether or not the user is doing, and “Fair trade” indicating whether or not the user approves of the fair trade are stored in association with each other.

  The server resource information storage unit 13b stores information regarding the power source used by each server 30 as information regarding the resource of each server 30. It is assumed that information stored in the server resource information storage unit 13b is stored in advance.

  For example, as illustrated in FIG. 4, the server resource information storage unit 13 b includes a “server ID” that uniquely identifies the server, an “energy” that indicates whether the energy used by the server is renewable energy, A “fair trade” indicating whether or not the server is using energy supplied by performing a fair trade is stored in association with each other.

  Returning to FIG. 2, the control unit 12 includes a reception unit 12a, a selection unit 12b, a request unit 12c, and a connection control unit 12d. Here, the control unit 12 is an electronic circuit such as a CPU (Central Processing Unit) or MPU (Micro Processing Unit), or an integrated circuit such as an ASIC (Application Specific Integrated Circuit) or an FPGA (Field Programmable Gate Array).

  The receiving unit 12 a receives policy information related to the execution environment of the application designated by the user of the client terminal 20. Specifically, the receiving unit 12a receives, as policy information, information related to the power source used by the server 30 that can execute processing related to the application and information related to the operating source of the server that executes the application. For example, the information on the power source may be received by the receiving unit 12a as information on designating the energy used by the server 30 as renewable energy, information on excluding the server 30 using energy generated by nuclear power generation, or fair trade. Receive information that you agree. In addition, for example, the receiving unit 12a receives the name of the company that operates the server, the name of the server operator that is highly evaluated by a third party, and the like as information about the server that executes the application. Also good.

  The selection unit 12b selects the server 30 that executes processing related to the application according to the policy information received by the reception unit 12a. Specifically, the selection unit 12b selects a server that executes processing related to the application based on the received information related to the power source or information related to the management source of the server that executes the application. For example, when the company name “Company A”, which is the server operator, is specified as the information related to the server operator that executes the application, the selection unit 12b selects the server operated by “Company A”. . Moreover, below, the process which selects a server when the information regarding an electric power source is received is demonstrated.

  Here, a process of selecting an execution environment to be used by the user for the application process according to the policy information will be described with reference to the example of FIG. FIG. 5 is a diagram for explaining that the user can select an execution environment used for application processing according to a policy. For example, in the example of FIG. 5, the server 30A is a server that uses renewable energy, although the power source is energy from thermal power + solar power generation, and the power generation operation rate is low during morning and evening hours. Further, the server 30B is a server that uses energy from geothermal power generation as a power source and can contribute to the region by performing fair trade. The server 30C is a server that uses energy generated by nuclear power generation as a power source and uses energy that may have a risk in an emergency.

  The client terminal 20 is set with “◯ ECO (renewable energy)”, “× Nuclear power”, “○ Fair trade approval”, and “Current time 20:25” as policy information. Here, “◯ eco (renewable energy)” means that the user designates a server that uses renewable energy as an eco server as a target server of the application execution environment. “× Nuclear” means that the user excludes a server that uses nuclear energy from the application execution environment. In addition, “○ Fair Trade Agree” means that the user agrees with the Fair Trade.

  In this case, the selection unit 12b of the lookup server 10 uses the renewable energy and selects the server 30B that uses the energy supplied by the fair trade. And the connection control part 12d mentioned later controls so that the server 30B and the client terminal 20 may be connected. As a result, the offloader of the client terminal 20 offloads to the server desired by the user, and the user can select the power source used for the application processing by himself.

  Here, a specific processing flow of policy determination processing for selecting a server according to a policy will be described with reference to an example of FIG. FIG. 6 is a diagram for explaining policy determination processing. As illustrated in FIG. 6, the selection unit 12b acquires policy information from the client terminal 20 (step S1). Here, the selection unit 12b stores the acquired policy information in the policy information storage unit 13a.

  Then, the selection unit 12b extracts the resource information from the server resource information storage unit 13b (Step S2), and proceeds to the policy determination process. First, when the policy information specifies “renewable energy” as the policy determination process, the selection unit 12b determines whether the data in the energy item of the resource information of each server matches “renewable energy”. (Step S3). As a result, when it is determined that the selection unit 12b does not match, that is, when there is no server that uses renewable energy, the request unit 12c described later requests an operation check from the nearest server 30C ( Step S4).

  If it is determined that the selection unit 12b matches, that is, if there is a server that uses renewable energy, it is determined as policy determination processing whether the policy information agrees with the fair trade (step) S5). As a result, when the trade trader does not agree with the fair trade, it is determined as a policy determination process whether the current time is a time zone in which the server 30A can be used (step S6). As a result, the selection unit 12b If it is determined that the time is available, the server 30A is selected. If the selection unit 12b determines that it is not the time when the server 30A can be used, the selection unit 12b proceeds to step S4, and the request unit 12c requests an operation check from the nearest server 30C.

  If the customer agrees with the fair trade, it is determined as a policy determination process whether the current time is within a time zone in which the server 30B can be used (step S7). As a result, if the selection unit 12b determines that it is time to use the server 30B, the selection unit 12b selects the server 30B. If the selection unit 12b determines that it is not the time when the server 30B can be used, the selection unit 12b proceeds to step S4, and the request unit 12c requests an operation check from the nearest server 30C.

  The request unit 12c requests the server 30 to confirm whether or not the server 30 selected by the selection unit 12b is operating normally. For example, the request unit 12c transmits an operation check request to the server 30 whose conditions match the policy information. Then, the request unit 12c determines whether or not an operation check result has been received. When the operation check result is received, the request unit 12c confirms the operation check result content. Then, when the server 30 is operating normally, the request unit 12c transmits an instance generation request to the server 30.

  The connection control unit 12d controls the connection between the server 30 and the client terminal 20 selected by the selection unit 12b. Specifically, the connection control unit 12d confirms that the server 30 selected by the selection unit 12b is operating normally and receives the instance generation result, the server 30 and the client terminal 20 Control connection with.

  For example, the connection control unit 12d gives an instruction to connect to the server 30 using the ID and the IP address together with the ID for uniquely identifying the client terminal 20 and the IP address of the server 30 selected by the selection unit 12b. By transmitting to the client terminal 20, the connection between the selected server 30 and the client terminal 20 is controlled.

[Client terminal configuration]
Next, the configuration of the client terminal 20 will be described with reference to FIG. FIG. 7 is a block diagram showing the configuration of the client terminal according to the first embodiment. As illustrated in FIG. 7, the client terminal 20 includes a communication processing unit 21, a control unit 22, and a storage unit 23.

  The communication processing unit 21 controls communication related to various types of information exchanged with the connected lookup server 10, server 30, and the like. For example, the communication processing unit 21 transmits policy information to the lookup server 10, and receives an ID that can uniquely identify the client terminal 20 and the IP address of the connection destination server 30 from the lookup server 10.

  As shown in FIG. 7, the storage unit 23 includes a policy information storage unit 23a. The storage unit 23 is, for example, a semiconductor memory element such as a RAM or a flash memory, or a storage device such as a hard disk or an optical disk.

  The policy information storage unit 23 a stores policy information related to the execution environment of the application designated by the user of the client terminal 20. For example, as illustrated in FIG. 8, the policy information storage unit 23 a allows the user to reproduce the “terminal ID” that uniquely identifies the client terminal 20 that is the device itself and the energy that is used by the server that executes the process related to the application. “Energy” indicating whether or not energy is designated and “fair trade” indicating whether or not the user agrees with the fair trade are stored in association with each other.

  Returning to FIG. 7, the control unit 22 includes a reception unit 22 a, a determination unit 22 b, and a switching unit 22 c. Here, the control unit 22 is an electronic circuit such as a CPU or MPU, or an integrated circuit such as an ASIC or FPGA.

  The accepting unit 22a accepts policy information in response to a user input operation. Further, when receiving the policy information, the receiving unit 22a stores the received policy information in the policy information storage unit 23a. For example, the reception unit 22a includes, as policy information, information indicating that the energy used by the server 30 is designated as renewable energy, which is server resource information that is an external condition of the server, and the server 30 that uses energy generated by nuclear power generation. Receive information to exclude or to approve fair trade. As policy information received here, for example, in the case of an application that handles personal information, the application is executed from a security point of view in view of the policy of entrusting the processing to a server operator with high accreditation evaluation by a third party organization. The server company to be executed may be specified.

  The determination unit 22b determines whether the activated application is to be processed locally in the own device or offloaded to the server. Specifically, when the application is activated, the determination unit 22b determines whether the device itself is in an offloadable state and whether the application is offloadable. As a result, when the offload is not possible, the determination unit 22b processes the activated application locally in the own device. Further, when the offload is possible, the determination unit 22b transmits policy information to the lookup server 10 in order to cause the user to select a desired server.

  The switching unit 22c dynamically switches the call destination (and the communication destination). That is, when the determination unit 22b determines to execute the application process on the server 30 side, the switching unit 22c designates the call destination as the application model on the server 30 side, and causes the server 30 side to perform the process.

  When the determination unit 22b determines that the application process is locally executed on the client terminal 20 side, the switching unit 22c designates the call destination as a component of the model on the client terminal 20 side, and causes the processing to be performed locally. . Thereby, for example, even when the client terminal 20 is offline from the server 30, the application can be executed.

[Server configuration]
Next, the configuration of the server 30 will be described with reference to FIG. FIG. 9 is a block diagram illustrating a configuration of the server according to the first embodiment. As illustrated in FIG. 9, the server 30 includes a communication processing unit 31, a control unit 32, and a storage unit 33.

  The communication processing unit 31 controls communication related to various types of information exchanged with the connected client terminal 20, server 30, and the like. For example, the communication processing unit 31 receives an operation check request and an instance generation request from the lookup server 10, and transmits an operation check result and an instance generation result to the lookup server 10.

  As shown in FIG. 9, the storage unit 33 includes a server resource information storage unit 33a. The storage unit 33 is, for example, a semiconductor memory element such as a RAM or a flash memory, or a storage device such as a hard disk or an optical disk.

  The server resource information storage unit 33a stores information about the power source used by the server 30 as information about the resources of each server 30. For example, as illustrated in FIG. 10, the server resource information storage unit 33a has a “server ID” that uniquely identifies the server, and an “energy” that indicates whether the energy used by the server is renewable energy. And the “fair trade” indicating whether or not the server uses the energy supplied by performing the fair trade is stored in association with each other.

  Returning to FIG. 9, the control unit 32 includes an operation check unit 32a, a generation unit 32b, a transmission unit 32c, and an activation unit 32d. Here, the control unit 32 is an electronic circuit such as a CPU or MPU, or an integrated circuit such as an ASIC or FPGA.

  The operation check unit 32a checks whether the server 30 is operating normally. For example, when the operation check unit 32 a receives an operation check request from the lookup server 10, the operation check unit 32 a performs an operation check. Then, the operation check unit 32a notifies the transmission unit 32c of an operation check result that is a result of performing the operation check.

  After the operation check by the operation check unit 32a, the generation unit 32b generates an instance corresponding to the client terminal 20 on a one-to-one basis. For example, when the generation unit 32b receives an instance generation request from the lookup server 10, the generation unit 32b generates an instance and notifies the transmission unit 32c of the generated instance generation result.

  The transmission unit 32 c transmits an operation check result that is a result of the operation check performed by the operation check unit 32 a to the lookup server 10. Further, the transmission unit 32c transmits the instance generated by the generation unit 32b to the lookup server 10 as an instance generation result.

  The activation unit 32d activates an application and executes a process related to the application when the client terminal 20 requests the application process. Here, distributed processing by the client terminal 20 and the server 30 will be described with reference to FIG. FIG. 11 is a diagram for explaining distributed processing by a client terminal and a server.

  FIG. 11 shows a logical configuration of the client terminal 20 and the server 30 in the present embodiment. The client terminal 20 is provided with an execution environment 210 implemented by the mobile OS, and the application 220 is positioned above the execution environment 210. The application 220 is based on the MVC design pattern, and includes a view and control component and a model component.

  Below the execution environment 210, as hardware components, various sensors 230 such as a GPS (Global Positioning System) sensor, a battery fuel gauge, an acceleration sensor, and the execution of the application 220 are related. A storage (storage device) 240 for storing data and the like is provided. The storage 240 is configured by, for example, a memory card having a flash memory.

  Similarly, the server 30 is provided with an execution environment 310 realized by the OS, and an application 320 equivalent to the application 220 of the client terminal 20 is located above the execution environment 310. Below the execution environment 310, a virtual sensor 330 that simulates a sensor as a hardware component, and a storage (storage device) 340 that stores data related to the execution of the application 320 are provided. The storage 340 is configured by, for example, an HDD (Hard Disk Device).

  This function in the execution environment 210 of the client terminal 20 is provided with a switching unit 250 (corresponding to the switching unit 22c in FIG. 7) that is a mechanism for dynamically switching a call destination (and a communication destination). When the switching unit 250 that dynamically switches the call destination (and the communication destination) determines to execute the application process on the server 30 side, the switch unit 250 designates the call destination as the model of the application 320 on the server 30 side, and the server 30 The processing is performed on the side (“offload processing” described in FIG. 11).

  In addition, when the switching unit 250 that dynamically switches the call destination (and the communication destination) determines to execute the application process locally on the client terminal 20 side, the switching unit 250 sets the call destination to the client terminal 20. It is designated as a component of the model on the side and processed locally (“local processing” described in FIG. 11).

[Processing by system]
Next, processing by the system according to the first embodiment will be described with reference to FIG. FIG. 12 is a sequence diagram illustrating a processing procedure of the system according to the first embodiment.

  As illustrated in FIG. 12, the client terminal 20 determines whether to process the application locally or off-loading according to the operation mode when the application is activated (see FIG. 13). Is performed (step S101). If the client terminal 20 determines to perform off-load processing, the client terminal 20 transmits policy information to the lookup server 10 (step S102).

  Subsequently, the lookup server 10 performs a policy determination process (see FIG. 14) for selecting a server whose conditions match the policy (step S103). Then, the lookup server 10 transmits an operation check request and an instance generation request to the server 30 desired by the user (Step S104).

  Then, the lookup server 10 executes an instance creation process (see FIG. 15) for creating an instance corresponding one-to-one with the client (step S105), and transmits the operation check result and the instance creation result to the lookup server 10. (Step S106). Then, the lookup server 10 executes a connection instruction process (see FIG. 16) for transmitting the ID that can uniquely identify the client terminal 20 and the IP address of the connection destination server 30 to the client (step S107).

  Subsequently, the lookup server 10 transmits to the client terminal 20 a connection destination instruction for instructing connection to the server 30 together with the above ID and IP address (step S108). Thereafter, the client terminal 20 executes an offload process using the ID and IP address received from the lookup server 10 (step S109), and connects to the server 30 (step S110). In addition, after connecting to the client terminal 20, the server 30 activates the application (step S111) and executes processing related to the application.

[Operation mode judgment processing by client terminal]
Next, an example of operation mode determination processing by the client terminal 20 will be described with reference to FIG. FIG. 13 is a flowchart showing a processing procedure of operation determination processing of the client terminal according to the first embodiment.

  As illustrated in FIG. 13, when the application is activated (Yes in Step S201), the determination unit 22b of the client terminal 20 determines whether the device is in an offloadable state and an application that can be offloaded. (Step S202). For example, the determination unit 22b determines whether the operation mode of the client terminal 20 is the local mode or the cloud mode. When the operation mode is the local mode, the client terminal 20 processes the application locally. When the operation mode is the cloud mode, the client terminal 20 processes the application.

  As a result, when the offload is not possible (No at Step S202), the determination unit 22b processes the activated application locally in the own device (Step S204). In addition, when the offload is possible (Yes in Step S202), the determination unit 22b transmits policy information to the lookup server 10 in order to select a server desired by the user (Step S203).

[Policy judgment processing by lookup server]
Next, an example of policy determination processing by the lookup server 10 will be described with reference to FIG. FIG. 14 is a flowchart showing a processing procedure of policy determination processing of the lookup server according to the first embodiment.

  As shown in FIG. 14, when the receiving unit 12a of the lookup server 10 receives policy information from the client terminal 20 (Yes in step S301), the selecting unit 12b determines whether there is server resource information whose conditions match the policy information. (Step S302). As a result, when the selection unit 12b determines that there is server resource information whose conditions match the policy information (Yes in step S302), the request unit 12c sends an operation check request to the server 30 whose conditions match the policy information. Transmit (step S303). On the other hand, when the selection unit 12b determines that there is server resource information whose conditions match the policy information (No at Step S302), the request unit 12c transmits an operation check request to the nearest server 30 (Step S304). .

  Thereafter, the request unit 12c determines whether the operation check result has been received (step S305). When the operation check result is received (step S305 affirmative), the request unit 12c determines whether the server is operating normally (step S306). If it is operating (Yes at Step S306), an instance generation request is transmitted to the server 30 (Step S307). If the server is not operating normally (No at Step S306), it is determined that the process related to the application is to be processed locally (Step S308).

[Server instance creation processing]
Next, an example of instance generation processing by the server 30 will be described with reference to FIG. FIG. 15 is a flowchart illustrating a processing procedure of instance generation processing of the server according to the first embodiment.
