Description

  The present invention relates to an information processing apparatus, an information processing method, and a computer program that control data transmission.

  When a certain device transmits data to another device connected via a communication network (hereinafter referred to as “network”), the load on the network increases.

  For example, an information processing apparatus that collects log data (hereinafter referred to as “log”) in which a history indicating the operation or state of its own device is recorded and transmits the collected log to an external monitoring server or the like is generally used. Known. The log transmitted to the monitoring server is used to monitor threats such as information leakage, malfunction or unauthorized use that occur in the information processing apparatus. One of the purposes of collecting logs and transmitting them to the monitoring server is to analyze the cause of the threat when a threat occurs in the information processing apparatus. The amount of log information collected for such a purpose is generally enormous. If the information processing apparatus transmits a log with such an enormous amount of information to a monitoring server that is an external apparatus, the network bandwidth may be used up only by transmitting the log. In such a case, the original business of the information processing apparatus may be adversely affected.

  A technique called “traffic shaping” is an example of a technique for adjusting a load imposed on a network by data transmission. The technology called traffic shaping is a technology for adjusting a data transmission time interval and smoothing a transfer rate so as not to exceed a network bandwidth limited in advance.

  Patent Document 1 discloses an example of a technique using traffic shaping. The first transmission apparatus that performs traffic shaping includes a buffer that stores data to be transmitted. The first transmission device reads data from the buffer at a predetermined rate, performs traffic shaping, and transmits the read data to an external device. When the buffer resource is depleted, the first transmission device transmits data to the second transmission device that performs traffic shaping, and requests the second transmission device to perform traffic shaping. The second transmission device stores the data received from the first transmission device in a buffer, and reads the data to be shaped from the buffer. The second transmission device transmits the read data to the external device by performing traffic shaping.

  Patent Document 2 discloses an example of a technique for controlling transmission of event data. The technique disclosed in Patent Document 2 gives importance to event data. The technique disclosed in Patent Document 2 transmits all event data to an external device when the network load is low. The technique disclosed in Patent Document 2 transmits only event data assigned a high importance level to an external device when the network load is high. The technique disclosed in Patent Document 2 thus suppresses the influence of event data transmission on the network load.

JP 2012-175481 A Japanese Patent Laid-Open No. 10-028151

  However, the techniques disclosed in Patent Document 1 and Patent Document 2 have the following problems.

  The technique disclosed in Patent Document 1 requires a second transmission device that performs traffic shaping in addition to the first transmission device. For example, assume a system that includes a device that collects a log related to its own device and transmits the log to a monitoring server, and a monitoring server that receives a log from the device and analyzes a threat generated in the device. In this case, with the technology disclosed in Patent Document 1, the network load associated with data transmission cannot be adjusted only on the device side that collects the log.

  In the technique disclosed in Patent Document 2, a log assigned a low importance is transmitted with a delay. The technology disclosed in Patent Document 2 cannot be applied to an apparatus that is required to transmit a log assigned a low importance level without delay as much as possible. For example, assume a system that includes a device that collects a log related to its own device and transmits the log to a monitoring server, and a monitoring server that receives a log from the device and analyzes a threat generated in the device. In this case, in order to analyze the threat, the monitoring server side often requires a log that is considered not directly related to the detected threat or a log that is considered to be less important. When the technique disclosed in Patent Document 2 is applied to such a system, it is expected that the task of analyzing the threat may be delayed in some cases.

  Further, for example, a case is assumed where a device that transmits a log executes a log transmission application and another application at the same time. In the technology disclosed in Patent Document 2, when the network load is low, the log transmission application is executed without considering the influence of the operation of the log transmission application on the communication executed by other applications. Therefore, when it is desired to prioritize communication executed by another application over communication executed by the log transmission application, the technique disclosed in Patent Document 2 cannot be used.

  According to the present invention, the control on the device side that collects data to be transmitted and transmits the data to the outside does not increase the network load, without a large delay, and to the communication executed by another application. The main purpose is to provide a technology capable of transmitting data while suppressing the influence.

  According to a first aspect of the present invention, there is provided a data collection unit that collects data to be transmitted, a buffer capable of storing data collected by the data collection unit, and data accumulated in the buffer via a network. A data transmission application to be transmitted to the outside, network load information that is information relating to the load on the network, buffer accumulation information that is information relating to the amount of data accumulated in the buffer, and other information that operates on its own device The network bandwidth used by the data transmission application and the transmission based on the application influence information which is information on the influence of the operation executed by the data transmission application on the communication executed by the application of interest among the applications Amount of data sent A transmission control unit for controlling an information processing apparatus including a.

  A second aspect of the present invention provides a data collection unit that collects data to be transmitted, a buffer capable of storing data collected by the data collection unit, and data accumulated in the buffer via a network. A data transmission application that transmits data to the outside, acquires network load information related to the load on the network, acquires buffer storage information that is information related to the amount of data stored in the buffer, and The application load information, which is information related to the influence of the operation executed by the data transmission application on the communication executed by the application of interest among other applications operating on the apparatus, is acquired, the network load information, and the buffer accumulation Information and the application On the basis of the effect information, the data transmission application to control the transmission amount of bandwidth and data used, an information processing method.

  A third aspect of the present invention provides a data collection unit that collects data to be transmitted, a buffer that accumulates data collected by the data collection unit, and data that is accumulated in the buffer via a network. A process of acquiring network load information related to the load on the network in a computer comprising a data transmission application to be transmitted to the outside, and a process of acquiring buffer storage information that is information related to the amount of data stored in the buffer And processing for obtaining application influence information, which is information related to the influence of the operation executed by the data transmission application on the communication executed by the application of interest among other applications operating on its own device, and the network load information And the buffer accumulation information , Based on said application effect information, the process of controlling the transmission amount of bandwidth and data used the data transmission application is a program for executing the.

  The object of the present invention is also achieved by a computer-readable storage medium storing the above program.

  According to the present invention, the control on the device side that collects data to be transmitted and transmits the data to the outside does not increase the network load, without a large delay, and to the communication executed by another application. It is possible to provide a technology capable of transmitting data while suppressing the influence.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
<First Embodiment>
[Description of configuration]
FIG. 1 is a block diagram illustrating the configuration of the information processing apparatus 100 according to the first embodiment. In FIG. 1, the information processing apparatus 100 includes a data collection unit 110, a buffer 120, a data transmission application 130, another application 140, a first acquisition unit 150, a second acquisition unit 160, and a third acquisition unit. Acquisition unit 170 and transmission control unit 180. The information processing apparatus 100 is connected to the external device 90 via the network 900. The information processing apparatus 100 transmits the data collected by the data collection unit 110 to the external device 90. 1 shows one information processing device 100 and one external device 90, but a plurality of information processing devices 100 and a plurality of external devices 90 may be connected to the network 900.

  Next, each functional block of the information processing apparatus 100 will be described.

  The data collection unit 110 collects data to be transmitted. For example, data to be transmitted may be sequentially generated at a predetermined timing by a data generation unit (not shown) included in the information processing apparatus 100. The data collection unit 110 may acquire such data at a predetermined timing. Alternatively, the data collection unit 110 may collect data each time new data is generated. The data to be transmitted is, for example, a log that records a history representing the operation or state of the information processing apparatus 100. In this case, the data collection unit 110 collects logs related to the information processing apparatus 100.

  The buffer 120 accumulates data collected by the data collection unit 110.

  The data transmission application 130 transmits the data stored in the buffer 120 to the external device 90 via the network 900.

In the data transmission application 130, a usable bandwidth is set in advance. The usable bandwidth is the bandwidth of the network 900 that can be used by the data transmission process executed by the data transmission application 130. The usable bandwidth is preset in the data transmission application 130. Hereinafter, the usable bandwidth is referred to as “usable bandwidth”.

  How the usable bandwidth is determined will be described. In order to facilitate the understanding of the invention, the data transmission application 130 will be described as a log transmission application that transmits a log related to its own device. For example, consider a case where one external device 90 and ten information processing devices 100 are connected to a network 900 having a bandwidth of 100 Mbps (megabit per second). In this case, it is assumed that a bandwidth of 10 Mbps corresponding to 10% of the entire log transmission processing by all the information processing apparatuses 100 is defined. In this case, the usable bandwidth allowed for the log transmission processing of one information processing apparatus 100 is 10 Mbps / 10 units = 1 Mbps. Here, in this embodiment and embodiments described later, “/” is a symbol representing division. It should be noted that the percentage of the total usable bandwidth of the entire log transmission process is determined based on the actual bandwidth information used in the past in the network. It is assumed that a value that does not overflow the bandwidth of the entire network is determined even when is used. For example, when the past average of the bandwidth used in the network is 80%, it is unlikely that congestion will occur even if the usable bandwidth of the entire log transmission process is set to 10%. If set, congestion is likely to occur. In this case, the usable bandwidth of the entire log transmission process is set to 10% in advance.

  The data transmission application 130 transmits the data for the transmission amount determined by the transmission control unit 180 described later using the bandwidth controlled by the transmission control unit 180 among the data stored in the buffer 120. As will be described later, in principle, the transmission control unit 180 controls the bandwidth of the network used by the data transmission application 130 within the range of the usable bandwidth predetermined for the data transmission application 130. However, when a specific condition is satisfied, the transmission control unit 180 causes the data transmission application 130 to transmit data with a bandwidth that exceeds the usable bandwidth predetermined for the data transmission application 130.

  The other application 140 is an application other than the data transmission application 130 that operates in the information processing apparatus 100. When the information processing apparatus 100 is a computer used for some business, the other application 140 is an application related to the original business of the information processing apparatus 100, for example. The other application 140 and the data transmission application 130 share resources such as a CPU (Central Processing Unit), a memory, or a NIC (Network Interface Card). The other application 140 downloads data or an application or transmits data via the network 900, for example. There may be one or more other applications 140. Hereinafter, among the other applications 140, an application of particular interest is referred to as an “application of interest”.

  The first acquisition unit 150 acquires network load information representing the load on the network 900. Here, the load applied to the network refers to the load applied to the network 900 connecting the information processing apparatus 100 and the external apparatus 90. For example, the network load information may be measurement information measured regarding transmission processing by the data transmission application 130. The measurement information may be a round trip time (RTT) or an amount of data for which transmission is completed per unit time (a response indicating reception completion is received). The network load information may be information generated based on past measurement information fluctuations.

  Specifically, if the measured RTT value continues to increase, the network load information is information indicating that the network for the next transmission process is busy. Further, if the measured transmission completion data amount per unit time continues to increase, the network load information is information indicating that the network for the next transmission processing is busy.

  The second acquisition unit 160 acquires buffer accumulation information based on the accumulation amount of data accumulated in the buffer 120. The buffer accumulation information is information indicating the accumulation amount of data accumulated in the buffer 120, for example. The buffer accumulation information may be information indicating a change rate (buffer accumulation rate) of the accumulation amount (buffer accumulation amount) of data accumulated in the buffer 120, for example. The buffer accumulation rate is a value calculated by the following equation (1), for example.

  [Buffer accumulation rate] = ([Size of newly collected data] + [Size of data already accumulated in the buffer 12 and not yet transmitted]) / [Amount of buffer accumulated when the previous transmission processing is performed] ] ... (1).

  Further, the “accumulated amount of the buffer when performing the previous transmission process” represents the size of the data accumulated in the buffer 120 when the data transmission application 130 transmitted the previous data.

  The buffer accumulation information may be information representing the average value of the buffer accumulation rate in the most recent predetermined period, for example.

  The buffer accumulation information may be, for example, information indicating the time required until all the logs accumulated in the buffer 120 at that time are transmitted with the communication throughput at that time. For example, the buffer accumulation information may be information in which trend information indicating a trend of fluctuation in communication throughput is added. The buffer accumulation information may be information representing the trend information of the buffer accumulation amount generated by a technique such as trend analysis, for example.

  The third acquisition unit 170 acquires application influence information, which is information regarding the influence of the operation of the data transmission application 130 on the communication executed by the application of interest. The third acquisition unit 170 acquires, for example, information obtained from an OS (Operating System) or information such as a NIC usage rate as application influence information.

  For example, the third acquisition unit 170 acquires the CPU usage rate of the data transmission application 130 and the CPU usage rate of the application of interest as application influence information. For example, when the CPU usage rate of an application of interest at a certain point in time is high, the use of the CPU by the data transmission application 130 may have some influence on the communication executed by the application of interest.

  The third acquisition unit 170 acquires, for example, the memory usage rate of the data transmission application 130 and the memory usage rate of the application of interest as application influence information. For example, when the memory usage rate of the application of interest is high at a certain point in time, the use of the memory by the data transmission application 130 may have some influence on the communication performed by the application of interest.

For example, the third acquisition unit 170 acquires, as application influence information, a rule that defines how a network bandwidth is allocated to an application of interest. For example, assume a specific application in which network bandwidth is allocated according to the rule “transmit at maximum speed as long as network bandwidth is free”. When such a specific application operates, when the data transmission application 130 executes data transmission,
Communication performed by a specific application is affected by the bandwidth used by the data transmission application 130.

  For example, the third acquisition unit 170 may acquire information related to activation or termination of the application of interest as application influence information.

The transmission control unit 180 is based on the buffer accumulation information, the network load information, and the application influence information.
The bandwidth of the network 900 used by the data transmission application 130 and the transmission amount of data are controlled. The transmission control unit 180 refers to the following three determination criteria when controlling the data transmission application 130.

  That is, a first criterion for determining whether or not the network is congested, a second criterion for determining whether or not data is accumulated in the buffer beyond a predetermined criterion, and This is a third determination criterion for determining whether or not the influence of communication executed by the application of interest can be tolerated.

  The transmission control unit 180 determines that the network is not congested based on the network load information and the first determination criterion, and data is stored in the buffer based on the buffer accumulation information and the second determination criterion. When it is determined that the data has been accumulated exceeding the reference, control is performed so that data transmission is performed using a bandwidth that exceeds a usable bandwidth predetermined for the data transmission application 130.

  The transmission control unit 180 determines that the network is not congested based on the network load information and the first determination criterion, and stores the buffer based on the buffer accumulation information and the second determination criterion. It is determined that data has not been accumulated beyond a predetermined standard, and based on the application influence information and the third determination standard, it has been determined that the influence received by the communication executed by the application of interest is unacceptable In this case, the data application is controlled to stop the operation of transmitting data for a predetermined time.

  FIG. 2 is a diagram illustrating an example of a hardware configuration of the information processing apparatus 100 illustrated in FIG.

  The hardware constituting the information processing apparatus (computer) 100 shown in FIG. 2 includes a CPU 1, a memory 2, a storage device 3, and a communication interface (I / F) 4. The information processing apparatus 100 may include the input device 5 or the output device 6. The functions of the information processing apparatus 100 are realized, for example, when the CPU 1 executes a computer program (software program, hereinafter simply referred to as “program”) read into the memory 2. In execution, the CPU 1 appropriately controls the communication interface 4, the input device 5, and the output device 6.

  Note that the present invention, which will be described by taking this embodiment and each embodiment described later as an example, is also configured by a nonvolatile storage medium 8 such as a compact disk in which such a program is stored. The program stored in the storage medium 8 is read by the drive device 7, for example.

  The communication executed by the information processing apparatus 100 is realized by the application program controlling the communication interface 4 using a function provided by the OS, for example. The input device 5 is, for example, a keyboard, a mouse, or a touch panel. The output device 6 is a display, for example. The information processing apparatus 100 may be configured by connecting two or more physically separated apparatuses in a wired or wireless manner.

  The hardware configuration example shown in FIG. 2 is also applicable to each embodiment described later. Note that the information processing apparatus 100 may be a dedicated apparatus. Note that the hardware configuration of the information processing apparatus 100 and each functional block thereof is not limited to the above-described configuration.

  The information processing apparatus 100 is connected to the external apparatus 90 via a network 900 configured by the Internet, a LAN (Local Area Network), a public line network, a wireless communication network, or a combination thereof. The external device 90 is configured by, for example, a computer device that includes a CPU, a memory, a storage device such as a hard disk, and a network interface.

[Description of operation]
The operation of the information processing apparatus 100 configured as described above will be described with reference to FIGS. 3, 4, and 5. The operation of the information processing apparatus 100 will be described separately for two operations, a data collection operation and a data transmission control operation.

  First, the data collection operation will be described. FIG. 3 is a flowchart for explaining a data collection operation executed by the information processing apparatus 100.

  The data collection unit 110 collects data to be transmitted (step S101).

  Next, the data collection unit 110 accumulates the collected data in the buffer 120 (step S102). As a result, the data stored in the buffer 120 without being transmitted in the data transmission control operation described later and the data newly collected in S101 are stored in the buffer 120.

  The data collection unit 110 repeats the above operation at a predetermined interval or timing when new data is generated.

  Next, the data transmission control operation will be described. FIG. 4 is a flowchart for explaining the data transmission control operation executed by the information processing apparatus 100.

  The first acquisition unit 150 acquires network load information that is information related to the load on the network 900 (step S201).

  The second acquisition unit 160 acquires buffer accumulation information that is information relating to the accumulation amount of data accumulated in the buffer 120 (step S202).

  The third acquisition unit 170 is application influence information that is information about the influence of the operation of the data transmission application 130 on the communication executed by the application of interest among other applications that operate on the own apparatus (information processing apparatus 100). Is acquired (step S203).

  Based on the network load information acquired in step S201, the buffer accumulation information acquired in step S202, and the application influence information acquired in step S203, the transmission control unit 180 determines the bandwidth used by the data transmission application 130 and the next time. The amount of data to be transmitted is determined (step S204). Details of the operation in step S204 will be described later.

  The data transmission application 130 transmits the data for the transmission amount determined in step S204 among the data stored in the buffer 120 to the external device 90 using the determined bandwidth (step S205). .

  The information processing apparatus 100 repeats the above operation according to a predetermined interval or a predetermined schedule. The order of operations from step S201 to step S203 is not limited to the order shown in FIG.

  Next, details of the operation in step S204 will be described with reference to FIG. FIG. 5 is a flowchart illustrating details of the operation in step S204 shown in FIG. The transmission control unit 180 uses the network load information acquired by the first acquisition unit and the first determination criterion for determining whether the network is congested to determine whether the network is congested. Is determined (step S301).

  The first determination criterion is, for example, a round trip time (RTT) or a threshold value for the amount of data for which transmission has been completed per unit time (a reception completion response has been received). When the transmission control unit 180 determines that the network is congested (YES in step S301), the transmission control unit 180 uses the bandwidth used by the data transmission application 130 within a predetermined usable bandwidth range. The width and the next data transmission amount are controlled (step S304).

  When the transmission control unit 180 determines that the network is not congested (NO in step S301), the transmission control unit receives the buffer accumulation information acquired by the second acquisition unit and the data in the buffer exceeds a predetermined standard. Based on the second determination criterion for determining whether or not the data is accumulated, it is determined whether or not the data is accumulated in the buffer exceeding a predetermined criterion (step S302). The second criterion is, for example, a buffer accumulation threshold or a buffer accumulation rate threshold.

  The second determination criterion may be, for example, a threshold value of a required time until all the logs accumulated in the buffer 120 at that time are transmitted with the communication throughput at that time. When the transmission control unit 180 determines that the data is stored in the buffer exceeding the predetermined reference (YES in step S302), the transmission control unit exceeds the usable bandwidth predetermined for the data transmission application 130. The bandwidth used by the data transmission application 130 and the next data transmission amount are controlled (step S307). Details of the operation described in step S307 will be described later.

  When the transmission control unit 180 determines that the data is not accumulated in the buffer exceeding the predetermined reference (NO in step S302), the transmission control unit includes the application influence information acquired by the third acquisition unit, Based on the determination criterion of 3, it is determined whether the operation of the data transmission application 130 can tolerate the influence of the communication executed by the application of interest (step S303).

  The third criterion is, for example, a threshold value for the CPU usage rate of the data transmission application 130 and the application of interest. The third criterion is, for example, a threshold value of the memory usage rate of the data transmission application 130 and the application of interest. The third criterion is that, for example, the content of a rule that determines how a network band is allocated to the application of interest satisfies a predetermined condition.

  For example, if the rule is a rule of “transmit at the maximum speed as long as the network bandwidth is free”, the third determination criterion determines that the influence of communication executed by the application of interest cannot be tolerated. To do. When the transmission control unit 180 determines that the influence on the application of interest cannot be permitted (YES in step S303), the transmission control unit 180 temporarily suspends the data transmission process of the data transmission application 130 (step S305). At this time, the time for temporary suspension may be a fixed value. The transmission control unit 180 may store the frequency of temporary suspension, and determine the time for temporary suspension based on the frequency.

  The period during which the transmission control unit 180 temporarily suspends the data transmission process executed by the data transmission application 130 is preferably longer than the time interval at which the information processing apparatus 100 performs the data transmission control operation. For example, if the data transmission control operation is performed every second, the temporary suspension period is 10 seconds.

When the transmission control unit 180 determines that the influence on the application of interest can be tolerated (NO in step S303), the transmission control unit 180 determines that the data transmission application 130 is within a predetermined usable bandwidth range. The bandwidth to be used and the next data transmission amount are controlled (step S306).
Details of the operation in step S307 will be described here.

  The transmission control unit 180 may determine a predetermined bandwidth that is predetermined as a bandwidth that exceeds the usable bandwidth. For example, when the usable bandwidth of the data transmission application 130 is determined to be 1 Mbps, the transmission control unit 180 determines 2 Mbps as the bandwidth exceeding the usable bandwidth, and determines the transmission amount that can be transmitted at 2 Mbps. Also good. Further, in this case, the transmission control unit 180 may determine a transmission amount that is increased stepwise for each transmission process while the network load information does not satisfy a predetermined congestion condition.

  If the bandwidth that exceeds the usable bandwidth has been determined in the previous transmission processing of the data transmission application 130, the transmission control unit 180 newly determines a bandwidth that does not exceed the usable bandwidth. If the bandwidth that does not exceed the usable bandwidth is determined in the previous transmission processing of the data transmission application 130, the transmission control unit 180 does not need to change the bandwidth. Also in this case, the transmission control unit 180 may determine the transmission amount to be increased step by step for each transmission process while the network load information does not satisfy a predetermined congestion condition.

  In addition, when the network load information satisfies a predetermined congestion condition, the transmission control unit 180 determines a bandwidth that does not exceed the usable bandwidth and is smaller than the current bandwidth, and performs the transmission based on the determined bandwidth. The amount may be controlled. For example, when the available bandwidth is 1 Mbps and the previously used bandwidth is 1 Mbps, the transmission control unit 180 may determine a bandwidth of 0.1 Mbps. In this case, the transmission control unit 180 may dynamically determine the transmission amount to be transmitted with the determined bandwidth by using trend analysis or the like. For example, the transmission control unit 180 predicts the network load at the time of executing the next transmission process using the trend information based on the trend analysis, thereby reducing the transmission amount smaller than the current time according to the predicted degree of the network load. It may be determined dynamically. Alternatively, the transmission control unit 180 may determine a transmission amount (for example, 1 byte) of a predetermined small size predetermined in such a case.

  Next, effects produced by the information processing apparatus 100 according to the first embodiment will be described.

  The information processing apparatus 100 according to the first embodiment collects data to be transmitted and transmits the data to the outside without controlling the network load without a large delay, and without a large delay. It is possible to provide a technology capable of transmitting data while suppressing the influence on communication executed by another application.

  This is because the transmission control unit 180 controls the bandwidth and data transmission amount used by the data transmission application 130 based on the network load information, the buffer accumulation information, and the application influence information.

  The information processing apparatus 100 according to the first embodiment performs data transmission when data is stored in a buffer exceeding a predetermined reference and the network load during the next transmission processing is not expected to be high. The bandwidth and transmission amount used in the next transmission process are controlled beyond the usable bandwidth set in the application 130. Thereby, the information processing apparatus 100 according to the first embodiment can reduce the buffer accumulation amount. As a result, according to the present embodiment, it is possible to reduce logs in which a delay occurs between collection and transmission.

  The information processing apparatus 100 according to the first embodiment is set in the data transmission application 130 regardless of the buffer accumulation information when the load on the network is expected to be high when the next transmission process is executed. Within the range of usable bandwidth, the bandwidth and transmission amount used in the next transmission process are controlled. Thereby, the information processing apparatus 100 according to the first embodiment can suppress network congestion.

  When the information processing apparatus 100 according to the first embodiment cannot tolerate the influence of the communication performed by the application of interest from the operation of the data transmission application 130, the data processing apparatus 100 can perform data processing even when the network is free. The data transmission process of the transmission application 130 is temporarily suspended. Thereby, the information processing apparatus 100 according to the first embodiment can suppress the influence of the operation of the data transmission application 130 on the communication executed by another application.

<Second Embodiment>
Next, a second embodiment based on the information processing apparatus 100 according to the first embodiment described above will be described.

  FIG. 6 is a diagram illustrating a configuration of an information processing system 1000 including load distribution apparatuses 200A and 200B according to the second embodiment.
