Description

  The present invention relates to a resource allocation device, a resource allocation system, a resource allocation method, and a program. In particular, the present invention relates to a resource allocation system that adjusts the resource allocation of embedded devices.

  In a conventional embedded device, a set of provided functions and operation tasks is determined in advance, so that resource allocation can be determined by adjusting resource allocation before shipping. However, on some new software platforms such as Android (registered trademark) for mobile terminals, users can freely install and execute additional applications, so in the allocation of computer resources determined before shipment, In some cases, inconvenience occurred.

In addition, there may be cases where the user additionally downloads an application from the outside, causing a runaway under certain conditions, or an originally malicious application that wastes computer resources and affects system operation. It became so.
In response to such changes in the new situation, measures to ensure the stability of basic functions provided by individual embedded devices are becoming more important.

  Some conventional resource allocation systems determine a resource allocation amount that provides the best application operation from the user's perspective. This resource allocation system adjusts and determines resource allocation by providing user interface means for obtaining feedback information from the user according to the amount of change in resource allocation (see, for example, Patent Document 1).

  In addition, a mechanism for limiting task operations to an upper limit value of computer resource allocation by a resource management function in the operating system is disclosed (for example, see Non-Patent Document 1).

  The resource group change control unit 302 sets and changes the upper limit value for each resource group. In addition, the resource group change control unit 302 performs task affiliation and withdrawal from each resource group, and movement between resource groups. Based on the allocation information stored in the resource group definition file 303 (information on the upper limit value of the allocation amount allocated to each task), the resource group change control unit 302 allocates the allocation amount indicated by the corresponding upper limit value for the task. It is an example of the allocation part which allocates these resources. Further, the resource group change control unit 302 receives a change request 504 (to be described later) from the resource manager 503, and based on the input change request 504, an allocation unit (allocation change unit) that changes the allocation amount of resources to be allocated to tasks. ).

  The resource group definition file 303 is a file in which a type, an upper limit value, and a task to be assigned are described in association with each of a plurality of resource group names. The resource group definition file 303 can hold and replace a plurality of definition sets of a plurality of files. The resource group definition file 303 is an example of an allocation information storage unit that stores allocation information in which an upper limit value of an allocation amount of resources allocated to a task is set.

  The resource group information notification unit 304 receives an event notification issued when the resource group monitoring control unit 206 in the OS execution unit 200 detects that the upper limit value of the resource group has been exceeded. When the resource group information notification unit 304 receives the event notification transmitted from the resource group monitoring control unit 206, the resource group information notification unit 304 notifies the resource manager 503 of arrival notification information indicating that the resource usage of the resource group has reached the upper limit value. . The resource group information notification unit 304 is an example of a notification unit that outputs arrival notification information indicating that the resource usage has reached the upper limit when it is determined that the resource usage has reached the upper limit. .

The resource group information recording unit 305 stores the event notification received by the resource group information notification unit 304. This event notification includes resource group information including excess information on the upper limit value of the resource group.
Resource group information includes information on the type of resource group that exceeded the upper limit of the resource group, the excess value, the time when the excess occurred (excess occurrence time), the number of times of excess, the excess information on the upper limit of the resource group such as the belonging task, etc. Including.

The resource group X400 and the resource group Y401 are resource allocation setting units, and are managed by the resource allocation mechanism unit 300.
A task A 500, a task B 501 and a task C 502 are a task group constituting an application (user application) and belong to any resource group. Duplicate affiliation of tasks is not allowed.

Here, as an example, two resource groups of resource group X400 and resource group Y401 are assumed, but the number of resource groups may not be two. For example, 1, 3, 4, or 5 or more may be generated.
The number of tasks is also an example, and the number of tasks is not limited to three, and may be three or more or three or less.

  Upon receiving the arrival notification information from the resource group information notification unit 304, the resource manager 503 determines whether or not the resource allocation needs to be changed based on the individual conditions for each system, and changes the resource allocation mechanism unit 300 if necessary. A request 504 is issued. The resource manager 503 inputs arrival notification information, generates change information used to change the amount of resources allocated to a task based on the input arrival notification information, and outputs the generated change information as a change request 504 It is an example of the management part which performs.

  Further, the resource manager 503 may be omitted. If the resource manager 503 does not exist, the resource group information notification unit 304 determines whether or not to change the resource allocation based on a certain condition, and if necessary, resource group change control. A change request 504 is issued to the unit 302. At this time, the resource group information notification unit 304 is an example of a management unit.

The resource allocation change condition 306 is a change that stores in the storage device change condition information that associates a change requirement that is a necessary condition for changing the resource allocation amount with an allocation change method that satisfies the change requirement condition. It is an example of a condition storage unit.
The resource manager 503 (management unit) determines whether or not the resource allocation amount needs to be changed based on the change necessary condition included in the resource distribution change condition 306 stored in the change condition storage unit. When it is determined that the resource allocation amount needs to be changed, the resource manager 503 generates a change request 504 (an example of change information) that requests a resource change based on the change method included in the change condition information.

  The configuration in FIG. 2 is merely an example of the hardware configuration of the resource allocation device 1000 and the resource allocation adjustment device 1001, and the hardware configuration of the resource allocation device 1000 and the resource allocation adjustment device 1001 is described in FIG. It is not limited to this configuration, and other configurations may be used.

Next, the operation of the resource distribution device 1000 according to this embodiment will be described.
FIG. 3 is a flowchart showing a resource allocation process (process) in the resource allocation method of the resource allocation apparatus 1000 according to the present embodiment.
The resource allocation process (process) of the resource allocation device 1000 will be described with reference to FIG.

In step ST100, the resource distribution device 1000 activates the resource distribution mechanism unit 300 and executes initialization processing when the system is activated.
In step ST101, the resource group generation management unit 301 in the resource distribution mechanism unit 300 reads the resource group definition file 303 stored in the storage device.

FIG. 4 is a diagram showing an example of the configuration of the resource group definition file 303 according to this embodiment.
As shown in FIG. 4, the resource group definition file 303 includes a file for defining the resource group for each resource group name. In the file, a resource type, an upper limit value, and a task name are associated and set.
In the resource group X, as a set of “resource type, upper limit value, task name”, “CPU, 20%, task A”, “CPU, 40%, task B”, “memory, 10%, task A”, A set of “memory, 30%, task B” is set.

In step ST102, the resource group generation management unit 301 generates a plurality of resource groups by the processing device based on the read resource group definition file 303.
In step ST103, the resource group change control unit 302 sets an upper limit value of resource allocation for each generated resource group.

In step ST104, the resource distribution device 1000 sequentially starts tasks (user applications (applications)) and performs initialization processing as system activation processing.
In step ST105, the resource group change control unit 302 designates the task identifier of the activated task, and causes the designated task to belong to the resource group based on the resource group definition file 303 (allocation process (process)).

  In step ST106, the resource distribution device 1000 executes normal operation of the task (user application) and continues its execution.

In step ST107, the resource group monitoring control unit 206 of the OS execution unit 200 determines whether or not each resource group has violated the upper limit value (determination step (processing)).
If the resource group monitoring control unit 206 detects exceeding the upper limit value of the resource group (YES in ST107), the resource group monitoring control unit 206 proceeds to ST108.
If the resource group monitoring control unit 206 has not detected exceeding the upper limit value of the resource group (NO in ST107), the resource group monitoring control unit 206 returns to ST106 and continues normal operation of the task.

  In ST108, the resource group monitoring control unit 206 issues an event notification including resource group information (resource group information) in conflict with the upper limit value to the resource group information notification unit 304. Further, the resource group monitoring control unit 206 requests the resource group information recording unit 305 to save the resource group information of the resource group that violates the upper limit value.

  In ST109, upon receiving the event notification from the resource group monitoring control unit 206, the resource group information notification unit 304 outputs arrival notification information indicating that the resource group has reached the upper limit value to the resource manager 503 (notification) Process (processing)). The arrival notification information includes resource group information of the resource group that has reached the upper limit value.

In step ST110, when the resource manager 503 receives the arrival notification information from the resource group information notification unit 304, the processing device determines whether or not to change the resource allocation based on the individual conditions for each system.
If the resource manager 503 determines that the resource distribution needs to be changed, the processing device generates a change request 504 that is a request for changing the resource distribution based on the individual conditions for each system. Then, the resource manager 503 issues a change request 504 to the generated resource group change control unit 302 (management process (process)). If the resource manager 503 determines that the resource allocation does not need to be changed, the resource manager 503 returns to ST106 and continues normal operation of the task.

Here, the individual condition for each system is, for example, the resource allocation change condition 306 (see FIG. 1) that is predetermined for the resource allocation apparatus 1000 and stored in the storage device.
For example, the resource allocation change condition 306 is a change necessary condition when the number of times that the resource usage reaches the upper limit value within a certain time is equal to or greater than a threshold, and the change amount of the allocated quantity when the change necessary condition is satisfied is changed. Remember as.
Alternatively, the resource allocation change condition 306 is a change necessary condition when the resource usage amount never reaches the upper limit value within a certain time, and the resource allocation amount is gradually reduced when the change requirement condition is satisfied. Is stored as a change method.

  Alternatively, the resource allocation change condition 306 has a change necessary condition that the upper limit value of each resource group is frequently exceeded within a certain time, and when the change requirement condition is satisfied, a new resource group is generated and the upper limit value is set. It is set as low and memorizing that the task belongs to the new group is stored as a change method. Further, the change method at this time may be set to forcibly terminate the task. Here, the task is, for example, a task of an external application that is additionally installed later (hereinafter referred to as an external task) or the like. By setting the resource allocation change condition 306 in this way, a runaway of an external task or the like occurs. The influence can be prevented.

  Alternatively, the resource allocation change condition 306 stores a change method described below, assuming that the resource usage amount never reaches the upper limit value within a predetermined time. The change method here is when an external task first belongs to a resource group for external application authentication (hereinafter referred to as a resource group for authentication), and the external task satisfies the change requirements in the resource group for authentication. In this method, the external task is moved to a resource group other than the resource group for authentication. By setting the resource allocation change condition 306 in this way, it is possible to confirm the safety of the external task and to prevent the external task from running away.

  Specifically, the resource allocation change condition 306 is, for example, “if the number of times the upper limit value is reached within a certain time exceeds the threshold value, the allocation amount (upper limit value is increased to 120%)”, “once within a certain time period” Also, if the upper limit value is not exceeded, the allocated amount (upper limit value is reduced in stages). If the resource allocation change condition 306 is a condition for determining whether to change the allocation amount (upper limit) for each device (system), whether to move or end the task, etc. It does not matter even if the condition.

  In ST111, the resource group change control unit 302 receives the resource group change request 504 from the resource manager 503, and changes the resource allocation of the resource group based on the received change request 504 (allocation step (process), allocation). Change process (process)). In addition, the resource group change control unit 302 changes the upper limit value of resource allocation in the resource group definition file 303 and the task to which the resource group belongs, for the resource group to be changed.

  In step ST112, the above processing is repeatedly executed as appropriate until there is a system termination request or a termination request from the resource distribution mechanism unit 300. In step ST113, upon receipt of the termination request from the resource distribution mechanism unit 300, termination processing is performed.

  In the above description, the resource group information notification unit 304 notifies the resource manager 503 of the arrival notification information in step ST109. However, when the resource manager 503 does not exist, the resource group information notification unit 304 may execute processing corresponding to steps ST110 to ST111 by the resource group information notification unit 304 itself.

  As described above, in the resource distribution device 1000 according to the present embodiment, when the excess of the preset upper limit value for each resource group is detected, the arrival notification information is sent to the resource manager 503 in the application layer. Therefore, it is possible to prepare (implement) a unique resource manager for each system and define a resource allocation change control process in accordance with the system policy and required specifications. In the first embodiment, the resource distribution change condition 306 is provided in the resource distribution mechanism unit 300. However, the resource distribution change condition 306 may be implemented in the application layer.

Also, for example, if the upper limit value for each resource group is exceeded within a certain time, how many times the upper limit value is expanded, or if the upper limit value is not exceeded within a certain time, the upper limit value is incremented. It is possible to define an algorithm for changing resource allocation such as reduction in size.
Also, if the upper limit of each resource group is frequently exceeded within a certain time, a resource allocation change algorithm is defined such that a new resource group is created, the upper limit is set lower, and the task belongs to that group. By doing so, it is possible to suppress the influence on the entire system based on the runaway due to the bug of the task or the security attack from the outside.
Also, when exceeding the upper limit value of each resource group is detected, the information on exceeding the upper limit value of the resource group is saved, so that the resource allocation is readjusted later by retrieving it outside the device as log information Reference data can be obtained, and resource allocation can be changed quantitatively.
In the present embodiment, the resource group information recording unit 305 is provided in the resource allocation mechanism unit 300. However, the resource group information recording unit 305 may be mounted on the application layer including the resource manager 503.
