Description

  The present invention relates to a program selection device, a program selection method, and a selection program.

  2. Description of the Related Art Conventionally, application programs that can be used in computers such as PCs (Personal Computers) or various devices having specific functions (hereinafter collectively referred to as “devices”) are roughly divided into two types. The application program of the first format is an application program that is installed in the device itself and causes the CPU of the device to execute the function of the application program. For example, a native application specialized in a specific hardware environment and software environment can be said to be a representative example of the first type of application program. The application program of the first format has an advantage that the influence of the communication load on the processing performance is small because the processing is often completed inside the device.

  The application program of the second format is an application program that is installed in a computer that can communicate with a device via a network, and that causes the CPU of the computer to execute processing in response to a request from the device. For example, it can be said that a Web application is a typical example of an application program of the second format. Since the application program of the second format is not installed for each device, there is an advantage that version upgrade is easy.

  Conventionally, in terms of functions, the first type of application program has the advantage of being able to provide functions using hardware unique to the device. However, the superiority of the first application program due to such advantages is becoming sparse.

  For example, in browser software included in a device for using a Web application, not only displays a screen but also interprets a script extended for device control (hereinafter referred to as “extended script”). There is also a thing which can perform control (for example, patent documents 1). An example of an extension script for an image forming apparatus is a script indicating a scan command. Therefore, in many cases, functions similar to those of the first format application program can be provided by the second format application program. In other words, an application program that realizes the same function can be provided by both the first format and the second format.

  The above situation can be said to be a favorable situation for the user in terms of an increase in options. However, when there are a plurality of application programs having a common use or function, the user may be confused or troublesome about which application program should be selected as an installation target on the device.

  The present invention has been made in view of the above points, and an object thereof is to automatically select a program suitable for an installation destination.

  Therefore, in order to solve the above-described problem, the present invention causes a receiving unit that receives an acquisition request for any of a plurality of programs that share some or all of the functions to each other, and causes the plurality of programs to be executed. And a selection unit that selects a program to be returned in response to the acquisition request based on the measurement result, and the measurement unit is a device to which the program is installed. The number of times of communication with an external device to be executed is counted, and the processing time is corrected by a value obtained by multiplying the number of times by a predetermined value.

  A program suitable for the installation destination can be automatically selected.

In the user environment E1, the multifunction machine 10a, the printer 10b, the projector 10c, the conference system 10d, and the like are connected via a network such as a LAN (Local Area Network).

  The development environment E3 is a system environment in a company (software vendor) that develops applications installed in devices. In the development environment E3, an application is developed using an API (Application Program Interface) published on an application platform mounted on the device. The development environment E3 includes one or more developer terminals 30 and the like. The developer terminal 30 is an information processing apparatus such as a PC (Personal Computer) used by an application developer.

  In this embodiment, the term developer is used for convenience, but the developer does not have to be actually developing. It may be a person who can be a notification destination of a failure in a device, such as a person in charge of a window or an administrator. Further, the developer does not have to be an individual. Usually, development of one application or failure handling is performed by a plurality of individuals or organizations. Therefore, the developer may be the entire development environment E3 (software vendor) or may be a contractor for development. Further, the developer does not necessarily have to be an organization that conducts development. It may be a call center or the like that accepts a failure related to a device.

  A program that realizes processing in the program providing apparatus 20 is provided by a recording medium 201 such as a CD-ROM. When the recording medium 201 storing the program is set in the drive device 200, the program is installed from the recording medium 201 to the auxiliary storage device 202 via the drive device 200. However, it is not always necessary to install the program from the recording medium 201, and the program may be downloaded from another computer via a network. The auxiliary storage device 202 stores the installed program and stores necessary files and data.

  The memory device 203 reads the program from the auxiliary storage device 202 and stores it when there is an instruction to start the program. The CPU 204 executes a function related to the program providing apparatus 20 according to a program stored in the memory device 203. The interface device 205 is used as an interface for connecting to a network.

  FIG. 3 is a diagram illustrating a functional configuration example of the program providing apparatus according to the embodiment of the present invention.

  In FIG. 3, the program providing apparatus 20 includes a request receiving unit 211, a reply candidate determining unit 212, a reply target selecting unit 213, an evaluation environment building unit 214, an automatic evaluation unit 215, a response reply unit 216, and the like. Each of these units is realized by processing executed by the CPU 204 by a program installed in the program providing apparatus 20. However, each unit may be distributed over a plurality of computers.

  The program providing apparatus 20 also uses a function classification information storage unit 221 and a module storage unit 222. Each of these storage units can be realized using, for example, the auxiliary storage device 202 or a storage device connected to the program providing device 20 via a network.

  The request receiving unit 211 receives an application download request from the multifunction machine 10a. In the present embodiment, an example in which a download request is transmitted from the multifunction machine 10a to which the application is installed is described. However, for example, the application may be downloaded by a PC (Personal Computer) or the like.

  The reply candidate determination unit 212 determines application candidates (hereinafter referred to as “reply candidates”) that can be a reply target for the download request with reference to the function classification information storage unit 221.

  The function classification information storage unit 221 stores information obtained by classifying (grouping) applications based on functions. In other words, the function classification information storage unit 221 stores correspondence information between functions and applications.

  The evaluation environment construction unit 214 constructs (generates) an environment (hereinafter referred to as “evaluation environment 250”) for evaluating the performance (processing time) of each reply candidate when there are a plurality of applications as reply candidates for the download request. ) The evaluation environment 250 is a virtual environment that imitates or has a hardware configuration and a software configuration similar to or substantially the same as the multifunction peripheral 10a that is the download request source. The expression “virtual environment” is not an environment constructed using the actual multifunction device 10a, but an environment in which the hardware configuration and software configuration similar to those of the multifunction device 10a are reproduced virtually (in software). Based.

  As shown in FIG. 3, the evaluation environment 250 includes a hardware imitation unit 251, a platform imitation unit 252, and the like. The hardware imitation unit 251 imitates the hardware of the multifunction machine 10a. The hardware imitation unit 251 may be capable of imitating the hardware of the multifunction machine 10a on the surface. That is, the hardware imitation unit 251 provides an interface similar to that of the hardware of the multifunction peripheral 10a, and the operation corresponding to the calling of the interface may be a dummy. The platform imitation unit 252 may be realized by the same program group as the application platform included in the multifunction machine 10a, or the same program group as the application platform is modified for operation on the hardware imitation unit 251. It may be realized by a program group. That is, the platform imitation unit 252 imitates the actual application platform not only on the surface behavior but also on the internal logic.

  Note that the program providing apparatus 20 includes, for example, a program that causes a computer to function as the hardware imitation unit 251 (hereinafter, referred to as “hardware imitation program”) for each model of the multifunction peripheral 10a. Or the said program is one, and the difference according to a model may be made into the setting information with respect to the said program. Further, the program providing apparatus 20 includes, for example, a program that causes the computer to function as the platform imitation unit 252 corresponding to the version (hereinafter referred to as “platform imitation program”) for each version of the application platform included in the multifunction peripheral 10a. . The platform imitation unit 252 selects a hardware imitation program corresponding to the download request source multifunction device 10a model and a platform imitation program corresponding to the version of the application platform 122 of the multifunction device 10a, and activates these programs. As a result, the evaluation environment 250 is generated. The hardware imitation program and the platform imitation program may be generally realized by software called an emulator or a simulator.

  The evaluation environment construction unit 214 further combines a hardware imitation unit 251 corresponding to the model of the multifunction peripheral 10a as a download request source, a platform imitation unit 252 corresponding to the version of the application platform included in the multifunction peripheral 10a, and the like. For the environment 250, each reply candidate application is installed. The installed application is stored in the module storage unit 222. The module storage unit 222 stores the entity (program module) of each application that has been sold so far and is in the maintenance period.

  Note that the place where the evaluation environment 250 is constructed (where the hardware imitation program and the platform imitation program are activated) may not be the program providing apparatus 20. It may be a computer connected to the program providing apparatus 20 via a network. Alternatively, a virtual machine may be operated on the program providing apparatus 20 or the computer, and the evaluation environment 250 may be constructed on one of the virtual machines.

  The automatic evaluation unit 215 causes each reply candidate application to be executed in the evaluation environment 250 and evaluates its processing performance. In the present embodiment, evaluation of processing performance corresponds to measurement of processing time.

  The reply target selection unit 213 selects an application suitable for the download request source multifunction peripheral 10a as a download target based on the evaluation result of each reply candidate by the automatic evaluation unit 215. The response reply unit 216 acquires the module of the application selected by the reply target selection unit 213 from the module storage unit 222 and sends it back to the download request source.

  Hereinafter, a processing procedure executed by the program providing apparatus 20 will be described. FIG. 4 is a flowchart for explaining an example of a processing procedure executed by the program providing apparatus.

  In step S101, the request reception unit 211 receives a download request transmitted from the multifunction machine 10a.

  The download request is transmitted, for example, in response to an application selection operation on a screen displayed on the operation panel of the multifunction peripheral 10a and displaying a list of downloadable applications. The download request includes identification information of the selected application (hereinafter referred to as “application ID”). Alternatively, the download target may be selected in units of functions, not in units of applications. That is, the user may be allowed to select what function is desired to be executed. In this case, identification information (hereinafter referred to as “function ID”) of the selected function may be included in the download request.

  The download request further includes hardware configuration information and software configuration information of the multifunction peripheral 10a. The hardware configuration information of the multifunction machine 10a is model information indicating the model of the multifunction machine 10a, for example. The software configuration information of the multifunction machine 10a is, for example, version information of the application platform that the multifunction machine 10a has.

  Subsequently, the reply candidate determination unit 212 determines a reply candidate based on the application ID or function ID specified in the download request and the function classification information storage unit 221 (S102).

  FIG. 5 is a diagram illustrating a configuration example of the function classification information storage unit. In FIG. 5, the function classification information storage unit 221 lists, for each function ID, a list of application IDs of applications having the function indicated by the function ID (strictly speaking, applications that can cause the multifunction peripheral 10a to execute the function). Remember. That is, it can be said that the set of applications related to the application IDs associated with the same function ID is a set of applications that share some or all of the functions.

  In FIG. 5, for convenience, the function ID is written in Japanese such as “scan” and “print”, but may be an enumeration of numbers or symbols. Moreover, the granularity (fineness) of the function classification may be changed as appropriate.

  For example, when an application ID is specified in the download request, an application related to each application ID associated with the same function ID as the application ID is determined as a reply candidate. On the other hand, when the function ID is specified in the download request, the application related to each application ID associated with the function ID is determined as a reply candidate.

  Note that the applications related to the application IDs associated with the same function ID may have different mounting forms or mounting forms. For example, an application in which all processes are completed on the MFP 10a, an application that delegates some processes to an external service, or all processes are executed on a Web server (not shown), and only the screen display is displayed on the Web of the MFP 10a. Applications executed in the browser may be associated with the same function ID.

  Subsequently, the evaluation environment construction unit 214 generates an evaluation environment 250 (S103). Specifically, a virtual including a hardware imitation unit 251 corresponding to the model (model of the multifunction peripheral 10a) indicated by the model information included in the download request and a platform imitation unit 252 corresponding to the version information of the application platform. An environment is generated as the evaluation environment 250. The generation destination of the evaluation environment 250 may be a computer (not shown) connected to the program providing apparatus 20 via a network, or may be a virtual machine that operates on the computer or the program providing apparatus 20.

  Subsequently, the evaluation environment construction unit 214 acquires the program module of each reply candidate application from the module storage unit 222 and installs it in the evaluation environment 250 (S104). That is, the module storage unit 222 stores the program module of each application in association with the application ID.

  As described above, the evaluation environment 250 is generated so as to have a hardware configuration and a software configuration that simulates a hardware configuration and a software configuration of the multifunction peripheral 10a as a download request source. Therefore, it is possible to measure the processing time of each reply candidate in a state closer to the multifunction machine 10a where the application is installed.

  The subsequent steps S105 to S109 are a loop process for each reply candidate. In step S105, the automatic evaluation unit 215 sets one reply candidate as an evaluation target. Note that step S104 may be executed after step S105. In this case, in step S104, one reply candidate to be evaluated may be installed. Further, every time the evaluation target is changed, the uninstallation from the evaluation environment 250 may be executed for the application to be evaluated immediately before.

  Subsequently, the automatic evaluation unit 215 automatically executes the application to be evaluated in the evaluation environment 250 (S106). In automatic execution, the automatic evaluation unit 215 measures the processing time of the application. For example, the time required from when the execution instruction is input until the execution result is output is measured. The measurement value (processing time) is associated with the app ID to be evaluated and stored in the memory device 203, for example.

  When input parameters (setting information or the like) are required for an application, the input parameters may be stored in advance as a test scenario for each application, for example, in the auxiliary storage device 202 or the like. In the case of a batch application, the test scenario may be a parameter group given first. In the case of an interactive application, the test scenario may be information indicating an operation instruction given by the user.

  In addition, information indicating the start timing of processing time measurement and information indicating the end timing may also be stored, for example, in the auxiliary storage device 202 or the like for each application. The information indicating the start timing of processing time measurement is, for example, information indicating which input is performed and then measurement is started in a test scenario. The information indicating the end of processing time measurement is, for example, information indicating what kind of output is obtained from the application to be evaluated and the measurement is ended. Note that the automatic evaluation unit 215 may be realized using a known automatic evaluation system.

  The automatic evaluation unit 215 also counts the number of network communications by the application during automatic execution of the application. That is, in the case of an application that transmits a processing request to an external service or delegates processing to the outside, network communication occurs. The number of communications may be counted, for example, by counting the number of calls of a predetermined API by the application.

  When the measurement of the processing time is completed, the automatic evaluation unit 215 determines whether or not the communication count is 1 or more (S107). When the communication count is 1 or more, the automatic evaluation unit 215 corrects the processing time by adding a value obtained by multiplying the communication count by the predetermined value α to the measured processing time (S108). . In other words, the time required for the communication process can be different between the evaluation environment 250 and the multifunction peripheral 10a. This is because the distance to the communication partner, the communication path, and the like are different between the evaluation environment 250 and the multifunction peripheral 10a. Therefore, in step S108, the processing time is corrected so that a processing time closer to the processing time when the application is executed in the multifunction peripheral 10a is obtained. Details of step S108 will be described later.

  When steps S105 to S109 are executed for all reply candidates (Yes in S109), the reply target selecting unit 213, for example, based on the processing time stored in the memory device 204 in association with the application ID, A reply target is selected (S110). Specifically, the application ID having the shortest processing time is selected as a reply target.

  Subsequently, the response reply unit 216 acquires the program module related to the application ID selected by the reply target selection unit 213 from the module storage unit 222, and sends a response including the program module back to the multifunction peripheral 10a (S111). .

  In step S111, display data (for example, HTML data) for displaying a screen showing the measurement result of the processing time for each application may be returned to the multi-function peripheral 10a. The application selected via the screen displayed on the operation panel of the multifunction machine 10a may be downloaded to the multifunction machine 10a.

  Next, details of step S108 will be described. In this embodiment, three modes will be described. In any form, communication during automatic execution of an application is actually performed without being emulated.

  In the first embodiment, for example, a computer provided with an external service as a communication partner of an application is the program providing apparatus 20 itself, or connected to the same LAN (Local Area Network) as the program providing apparatus 20 Assume a case. In this case, the delay time due to communication during automatic execution of the application is considered to be negligibly small. In other words, it is considered that the processing time measured in automatic execution hardly includes communication time.

  Therefore, in step S108 of the first form, the estimated value of one communication time between the MFP 10a and the external service is set to a predetermined value α. For example, one communication time between the multifunction device 10a and the external service may be measured in advance by a ping command or the like, and the measured value may be an estimated value of the communication time between the multifunction device 10a and the external service. In this case, the measurement value may be specified in the download request. Alternatively, the time until the download request from the multifunction machine 10a reaches the program providing device 20 may be measured, and the estimated value may be determined based on the measured value. If the communication time between the program providing device 20 and the external service is negligibly small, the communication time between the multifunction device 10a and the program providing device 20 can be regarded as the communication time between the multifunction device 10a and the external service. It is because it thinks that there is.

  In the second mode, it is assumed that a computer on which an external service is installed is connected to the program providing apparatus 20 via the Internet or the like, for example. In this case, it is considered that the processing time measured in the automatic execution of the application includes a certain amount of delay time due to communication. However, the communication time between the program providing device 20 and the external service and the communication time between the multifunction peripheral 10a and the external service are not necessarily the same.

  Therefore, in step S108 of the second form, the estimated time of one communication time between the multifunction peripheral 10a and the external service determined in the same manner as in the first form, between the program providing apparatus 20 and the external service. A value obtained by subtracting one communication time is set to a predetermined value α.

  For example, if the estimated value of the communication time between the MFP 10a and the external service is 100 milliseconds, and the one-time communication time between the program providing apparatus 20 and the external service is 10 milliseconds, 100−10 = 90 m The second is set to a predetermined value α.

  Similarly to the second embodiment, the third embodiment assumes a case where a computer on which an external service is mounted is connected to the program providing apparatus 20 via the Internet or the like, for example. In the third mode, the communication time between the multifunction device 10a and the external service is regarded as the sum of the communication time between the multifunction device 10a and the program providing device 20 and the communication time between the program providing device 20 and the external service. .

  Therefore, in this case, it is only necessary to apply one communication time between the program providing apparatus 20 and the multifunction peripheral 10a to the predetermined value α. The communication time may be determined based on, for example, the time until a download request from the multifunction machine 10a reaches the program providing apparatus 20.

  The third form is advantageous in that it is not necessary to previously measure the communication time between the multifunction machine 10a and the external service.

  As described above, according to the present embodiment, it is possible to automatically select a program suitable for the multifunction machine 10a that is the installation destination of the application.

  In the present embodiment, the multifunction device 10a has been described as an example of the device. However, the present embodiment is applied to other image forming apparatuses such as the printer 10b and other devices such as the projector 10c. Also good. Further, the present embodiment may be applied to a device (not shown) such as a digital camera. Furthermore, the present embodiment may be applied to an information processing system such as the conference system 10d.

  The program providing apparatus 20 may be configured by a single computer or may be configured by a plurality of computers distributed on a network. Further, the program providing service may be provided as a cloud service.

  For example, FIG. 6 is a diagram illustrating an example in which the program providing apparatus includes a plurality of computers. FIG. 6 shows an example in which the program providing device 20 is configured to be distributed among a plurality of computers. FIG. 6 shows an example in which the program providing device 20 is configured by four or more computers, but the program providing device 20 may be configured by less than four computers.

  Moreover, the function which the program provision apparatus 20 has may comprise a part of integrated development environment. FIG. 7 is a diagram illustrating an example of an integrated development environment. In FIG. 7, the same parts as those of FIG. Further, in FIG. 7, the request receiving unit 211, the reply candidate determining unit 212, the reply target selecting unit 213, the response reply unit 216, and the function classification information storage unit 221 are omitted for convenience.

  7, the integrated development environment 40 further includes a front end unit 217, an authentication unit 218, an authentication information storage unit 223, a source code storage unit 231, a source code editing unit 232, a build unit 233, a test unit 234, and a debug unit 235. And a continuous integration unit 236 and the like.

  The front end unit 217 provides a GUI (Graphical User Interface) of the integrated development environment 40. For example, the GUI is composed of HTML data described in HTML (HyperText Markup Language). However, the GUI may be configured by a data format other than HTML data.

  The authentication unit 218 performs authentication of a user who requests use of the integrated development environment 40. Specifically, in the present embodiment, an application developer is a user of the integrated development environment 40. Therefore, the authentication unit 218 verifies the developer by comparing the authentication information (for example, the user name and password) input at the developer terminal 30 with the authentication information stored in the authentication information storage unit 223. Run. The authentication information storage unit 223 stores authentication information of each user (developer) who has a contract for using the integrated development environment 40.

  The source code storage unit 231 stores application source code. The source code editing unit 232 edits the source code to be edited in response to an instruction input via the source code editing screen displayed on the developer terminal 30. The build unit 233 executes build (compile, link, etc.) for the source code stored in the source code storage unit 231. The test unit 234 supports execution of tests related to the application after the build. The debugging unit 235 supports debugging related to the application after the build. For example, the continuous integration unit 236 automatically executes a build and a test on a source code that has not been built after being edited by the source code editing unit 232, and stores a program module of the application after the build as a module storage unit. Upload to 222.

  By making the function of the program providing apparatus 20 a part of the integrated development environment 40, it is possible to provide a more convenient service to the developer. That is, the developer builds the evaluation environment 250, executes the automatic evaluation in the evaluation environment 250, edits the source code of the application that receives the execution result of the automatic evaluation, and builds the edited source code in the same virtual space. , Post-build testing and debugging can be performed.
