Description

  The present invention relates to an ICT resource management device, an ICT resource management method, and a program.

  With the progress of broadband communication networks in recent years, companies providing various services have computer systems with server devices and storage devices, while users (enterprises and individuals) have terminal devices that can be connected to the communication network. There are increasing forms of holding and connecting a terminal device to a communication network to receive necessary services from a computer system. Such a form is called cloud computing. Server devices and storage devices constituting the computer system are called computer resources, and communication networks are called network resources. These are collectively called ICT (Information and Communication Technology) resources.

  In cloud computing, ICT resource management is important. For example, if the capacity of the communication network through which the terminal device and the computer system are connected is insufficient, it is difficult to provide a service from the computer system to the terminal device. On the other hand, if the capacity of the communication network is excessive compared to the actual demand, the cost will increase. This applies not only to network resources but also to computer resources such as server devices. For this reason, various techniques for estimating the required ICT resource amount have been proposed.

  For example, it has been proposed as a first related technique related to the present invention to increase the energy saving effect by operating only the minimum necessary server device at a necessary time (see, for example, Patent Document 1). Specifically, in the first related technique, in a cloud computing system connected to a plurality of terminal devices via a network, a short-term CPU load after a certain period of time based on the CPU load history of the server device. Calculate the predicted value and the long-term predicted value of the CPU load at a certain point in the future, and compare the current value of the CPU load with the short-term predicted value and the long-term predicted value, or add or stop the required number of server devices Calculate the number of powers.

  In addition, it is proposed as a second related technique related to the present invention to construct a highly secure communication network even when a large amount of traffic is simultaneously generated due to an earthquake (see, for example, Patent Document 2). ). Specifically, in the second related technology, a simultaneous large amount of traffic generated, which is an estimated value of traffic generated in the event of an earthquake, is calculated for each area based on past earthquake occurrence information. Based on the amount of traffic generated from the other areas for each area at the time of the earthquake, which is calculated based on the traffic volume generated simultaneously, the normal traffic volume for each area, and predetermined information The risk level is calculated, and the network facility expansion amount in each area is calculated based on the risk level.

  In a general method of adding the ICT resource when the demand cannot be met, there is a risk that the provision of the service is stopped. On the other hand, in the first and second related technologies related to the present invention, since the amount of ICT resources that will be required in the future is predicted, it is possible to avoid a service stop due to a future shortage of ICT resources.

  However, in the first and second related technologies related to the present invention, it is not assumed that the connected network or area changes due to movement of the terminal device. For this reason, it is difficult to predict in advance that a shortage of capacity will occur in some ICT resources due to movement of the terminal device. For example, in a cloud computing system in which there are a plurality of local communication networks and a relay network connecting the local communication networks, and a plurality of terminal devices and computer systems are connected to any of the local communication networks, the movement of the terminal devices If the local communication network to which the terminal device is connected is biased by this, a shortage of bandwidth occurs in the local communication network to which many terminal devices are connected, making it difficult to provide services.

  An object of the present invention is to provide an ICT resource management device that solves the above-described problem, that is, it is difficult to predict in advance an ICT resource shortage caused by movement of a terminal device. .

A communication facility management unit that compares the predicted traffic amount with the communication facility capacity of the local communication network to calculate a shortage of the communication facility capacity for each of the local communication networks.

The ICT resource management method according to the second aspect of the present invention is:
An ICT resource management method executed by a computer connected to any one of a plurality of local communication networks each connected to a relay network,
The terminal device of the service provided through the relay network and the local communication network from a computer system connected to any of the local communication networks to a plurality of terminal devices connected to any of the local communication networks Accumulate usage history for each

Then, the predicted traffic amount is compared with the communication facility capacity of the local communication network to calculate the shortage amount of the communication facility capacity for each local communication network.

Referring to FIG. 1, in the first embodiment of the present invention, a plurality of terminal devices 110, a computer system 120, an ICT resource management device 130, these terminal devices 110, a computer system 120, and an ICT resource management device 130 are provided. A plurality of connected local communication networks 140 and a relay network 150 connecting the local communication networks 140 are configured. In FIG. 1, there is one computer system 120, but two or more computer systems 120 may exist. In FIG. 1, the number of local communication networks 140 is three, but may be two, or four or more. In FIG. 1, the number of relay networks 150 is one, but two or more may be used.

  Each terminal device 110 includes a personal computer, a smartphone, a mobile phone, and the like. Each terminal device 110 is connected to the local communication network 140 by wire or wireless. Each terminal device 110 may be a portable terminal or a fixed terminal.

  The computer system 120 has at least one computer resource when the server device and the storage device are called computer resources. The computer system 120 is composed of a data center system, one computer system among a plurality of computer systems constituting the data center system, or a personal computer. The computer system 120 has a function of providing a service to the terminal device 110 in accordance with a request from the terminal device 110 or autonomously. The service to be provided is arbitrary. For example, it may be a service that provides content such as video, a function that provides application software functions as a service, a function that provides a storage function, or other It may be.

  The local communication network 140 is configured by an access network, an Ethernet work, or the like. The local communication network 140 may be either a wired communication network or a wireless communication network.

  The relay network 150 is configured by a relay line or the like.

  The ICT resource management device 130 has a function of managing ICT resources included in the system. In this embodiment, it has the management function regarding the local communication network 140 as an ICT resource. The ICT resource management device 130 includes a usage history management unit 131, a connection relationship generation unit 132, and a communication facility management unit 133.

  The usage history management unit 131 has a function of storing, in the storage, a usage history 134 for each terminal device of a service provided from the computer system 120 to the terminal device 110. The method by which the usage history management unit 131 acquires the usage history of the service is arbitrary. For example, the usage history management unit 131 may have a function of receiving a service usage history transmitted from the computer system 120 to the ICT resource management apparatus 130 periodically or every time the service is provided. Alternatively, it may have a function of receiving a service usage history transmitted from the terminal device 110 to the ICT resource management device 130 periodically or for each service usage. Alternatively, the usage history management unit 131 may have a function of inputting a service usage history from an external device connected to the ICT resource management device 130 by batch processing performed at night or the like.

  The connection relationship generating unit 132 monitors the movement of the terminal device 110 and connection relationship data 135 indicating the relationship between the terminal device 110 and the local communication network 140 to which the terminal device 110 may be connected based on the monitoring result. And a function of generating The method by which the connection relationship generation unit 132 monitors the movement of the terminal device 110 is arbitrary. For example, the connection relationship generation unit 132 detects the position of the terminal device 110 using a signal transmitted from a GPS (Global Positioning System) chip built in the terminal device 110 or wireless LAN base station information, and the detected position And the area covered by each local communication network 140 may be determined to determine the local communication network 140 to which the terminal device 110 may be connected. Alternatively, the connection relationship generation unit 132 analyzes the CDR (Call Detail Record) stored in the exchange to detect the exchange to which the terminal device 110 is connected, and the terminal device 110 determines from the correspondence relationship between the exchange and the local communication network 140. The connected local communication network 140 may be determined. Alternatively, the local communication network 140 to which the terminal device 110 is connected may be determined using the roaming control information. The connection relation data 135 may have any data structure as long as the correspondence relation between the terminal device 110 and the local communication network 140 to which the terminal apparatus 110 is connected or possibly connected can be clearly understood.

  The communication facility management unit 133 has a function of predicting the traffic amount for each local communication network 140 and a function of calculating the shortage amount of the communication facility capacity of the local communication network 140 based on the predicted traffic amount. Here, the traffic amount is, for example, the amount of data per unit time flowing through the communication network, or the number of logical communication paths (sessions, connections, etc.) that can be established simultaneously. The communication equipment capacity of the local communication network 140 is the bandwidth of the local communication network 140 or the maximum number of logical communication paths that can be established simultaneously.

  In the prediction of the traffic volume, the communication facility management unit 133 determines the amount of traffic for each local communication network 140 based on the usage history 134 under the connection status between the terminal device 110 specified by the connection relation data 135 and the local communication network 140. Predict traffic volume. Further, in calculating the shortage amount of the communication facility capacity, the communication facility management unit 133 compares the predicted traffic amount with the communication facility capacity of the local communication network 140, and the shortage amount of the communication facility capacity for each local communication network 140. Is calculated.

  Next, the operation of this embodiment will be described.

  In the system shown in FIG. 1, the usage history management unit 131 of the ICT resource management device 130 is provided for each terminal device of services provided to the plurality of terminal devices 110 from the computer system 120 through the relay network 150 and the local communication network 140. Usage history 134 is accumulated.

  In addition, the connection relation generation unit 132 of the ICT resource management apparatus 130 monitors the movement of the terminal apparatus 110 and generates connection relation data 135 indicating the relation between the terminal apparatus 110 and the local communication network 140 to which the terminal apparatus 110 may be connected. Generate.

  Then, the communication facility management unit 133 of the ICT resource management device 130 sets the local communication network 140 for each local communication network 140 based on the usage history 134 under the connection status between the terminal device 110 and the local communication network 140 specified by the connection relation data 135. Is calculated, and the predicted traffic volume is compared with the communication facility capacity of the local communication network 140 to calculate the shortage of communication facility capacity for each local communication network 140.

  Next, the effect of this embodiment will be described.

  According to the present embodiment, it is possible to predict in advance a shortage of communication equipment capacity of the local communication network caused by the movement of the terminal device 110. The reason is as follows.

  In general, the pattern in which the terminal device 110 uses the service (the tendency of the type and frequency of the service to be used) is not the same as other terminal devices and is often different. However, if attention is paid to the specific terminal device 110 Most cases are fixed. For this reason, the service usage pattern after a certain terminal device 110 moves to another local communication network can be estimated from the past service usage pattern of the terminal device 110, that is, the usage history. Accordingly, the movement of the terminal device 110 is monitored to generate connection relationship data 135 indicating the relationship between the terminal device 110 and the local communication network 140 to which the terminal device 110 may be connected, and is specified by this connection relationship data 135. If the amount of traffic for each local communication network 140 is calculated based on the usage history for each terminal device 110 under the connection status between the terminal device 110 and the local communication network 140, the terminal device 110 actually performs service at the destination. The traffic volume for each local communication network 140 can be predicted with a certain degree of accuracy at a time point before using. Then, if the predicted traffic volume is compared with the communication facility capacity of the local communication network 140, it becomes possible to predict in advance the shortage of the communication facility capacity for each local communication network. As described above, since the shortage of the communication facility capacity of the local communication network 140 can be predicted before the terminal device 110 actually uses the service at the destination, sufficient time for increasing the communication facility capacity can be provided. Can be secured.

  Moreover, according to this embodiment, since not only the movement of each terminal device 110 is monitored but also the traffic amount is predicted based on the usage history of each terminal device 110, more accurate prediction is possible. On the other hand, in the method of predicting the traffic amount for each local communication network 140 based on the number of terminal devices connected to the local communication network 140, it is difficult to accurately predict the traffic amount. The reason is that even if many terminal devices that hardly use the service move to a specific local communication network 140, the traffic amount of the local communication network 140 hardly increases, while a small number of terminal devices that frequently use the service This is because the traffic amount of the local communication network 140 is greatly increased even if the mobile terminal is moved to a specific local communication network 140.

[Second Embodiment]
Referring to FIG. 2, a computer 200 according to the second embodiment of the present invention is connected to any one of the plurality of local communication networks 140 connected to the relay network 150, and ICT It has a function to manage resources. The computer 200 of this embodiment is an example of a computer that implements the ICT resource management apparatus 130 of FIG.

The program 240P is a program that realizes various processing units by being read and executed by the processor 250, and an external device (not shown) or a storage medium via a data input / output function such as the communication I / F unit 210. (Not shown) is read in advance and stored in the storage unit 240.

  Main processing information stored in the storage unit 240 includes usage history 240A, connection relation data 240B, network topology information 240C, communication facility capacity information 240D, and computer system facility information 240E.

  The usage history 240 </ b> A is a usage history for each terminal device 110 of a service provided from the computer system 120 to the terminal device 110. FIG. 3 shows a configuration example of the usage history 240A. The usage history 240A in this example is composed of a usage history file 240A1 for each terminal device. Each usage history file 240A1 includes an identifier 240A2 of the terminal device 110 and history data 240A3 for each usage. Each history data 240A3 includes a service use date and time 240A4, an identifier 240A5 of the computer system 120 that provided the service, a service identifier 240A6 indicating the type of service used, and the computer system 120 and the terminal device 110 regarding the use of this service. Data amount 240 </ b> A <b> 2 transmitted / received between the terminal device 110, an identifier 240 </ b> A <b> 8 of the local communication network to which the terminal device 110 was connected when using the service, and other information (e.g., usage fee) 240 </ b> A <b> 9. The use date 240A4 may include a start time, an end time, and a day of the week.

  The connection relationship data 240B indicates the relationship between the terminal device 110 and the local communication network 140 to which it may be connected. FIG. 4 shows a configuration example of the connection relation data 240B. The connection relation data 240B in this example is matrix data in which the identifier of the terminal device 110 is the vertical axis, the identifier of the local communication network 140 is the horizontal axis, and the presence or absence of connection is associated with the axis intersection. For example, a logical value “1” is stored at the intersection of the first row and the second column. This is because the terminal device 110 specified by the terminal device identifier “1” in the first row and the local communication network 140 specified by the communication network identifier “2” in the second column are actually connected, or Indicates that there is a possibility of connection. A logical value “0” is stored at the intersection of the first row, the first column, and the third column. This is because the terminal device 110 identified by the terminal device identifier “1” in the first row, the local communication network 140 identified by the communication network identifier “1” in the first column, and the communication network identifier “3” in the third column. The local communication network 140 specified by “” indicates that the network is not actually connected or is not likely to be connected.

  FIG. 5 shows another configuration example of the connection relationship data 240B. The connection relation data 240B in this example is obtained by adding a connection history column to the connection relation data in FIG. In this connection history column, the identifier of the local communication network 140 to which the terminal device 110 was connected immediately before is described. For example, “3” described in the connection history on the first line specifies the connection destination immediately before the terminal device 110 specified by the terminal apparatus identifier “1” on the first line by the communication network identifier “3”. The local communication network 140 is shown. In FIG. 5, only the local communication network 140 connected immediately before is described in the connection history, but a certain number of past connection destinations may be described.

  The network topology information 240C is data indicating a connection relationship between communication networks (local communication network, relay network). FIG. 6 shows a configuration example of the network topology information 240C. The network topology information 240C in this example is matrix data in which the identifier of the communication network is set to the vertical and horizontal axes, and the presence or absence of connection is associated with the axis intersection. For example, a logical value “1” is stored at the intersection of the first row and the fourth column. This indicates that the communication network specified by the communication network identifier “1” in the first row and the communication network specified by the communication network identifier “4” in the fourth column are connected to each other. . A logical value “0” is stored at the intersection of the first row, the second column, and the third column. This is specified by the communication network specified by the communication network identifier “1” in the first row, the communication network specified by the communication network identifier “2” in the second column, and the communication network identifier “3” in the third column. This means that the communication network is not connected. When the same communication network is connected to a plurality of other communication networks, a plurality of logical values “1” appear in the same row (see, for example, the bottom row in FIG. 6).

  The communication facility capacity information 240D indicates the communication facility capacity of each local communication network 140. FIG. 7 shows a configuration example of the communication facility capacity information 240D. The communication facility capacity information 240D in this example is associated with the identifier of the local communication network, and is classified into two types: the bandwidth of the local communication network and the maximum number of logical communication paths that can be established simultaneously (maximum number of simultaneous connections). The communication equipment capacity is described. For example, the first line indicates that the bandwidth of the local communication network 110 specified by the communication network identifier “1” is 500 Mbps, and the maximum number of simultaneous connections is 10.

  The computer system facility information 240E indicates the relationship between the computer system 120 and the local communication network 140 to which it is connected. FIG. 8 shows a configuration example of the computer system facility information 240E. The computer system facility information 240E in this example is matrix data in which the identifier of the computer system 120 is the vertical axis, the identifier of the local communication network 140 is the horizontal axis, and the presence or absence of connection is associated with the axis intersection. For example, a logical value “1” is stored at the intersection of the first row and the second column. This indicates that the computer system 120 specified by the computer system identifier “1” in the first row and the local communication network 140 specified by the communication network identifier “2” in the second column are connected. ing. A logical value “0” is stored at the intersection of the first row, the first column, and the third column. This is because the computer system 120 specified by the computer system identifier “1” in the first row, the local communication network 140 specified by the communication network identifier “1” in the first column, and the communication network identifier “3” in the third column. "Indicates that the local communication network 140 identified by" is not connected. Since the computer system facility information 240E shown in FIG. 8 assumes the system shown in FIG. 1 in which only one computer system 120 exists, the number of rows is at most one. However, when there are a plurality of computer systems 120, there are as many rows as there are computer systems 120 as shown by broken lines in FIG. Further, the number of connected computer systems 120 per local communication network 140 is not limited to one, but may be a plurality (for example, refer to the first and second lines in FIG. 8).

  The processor 250 has a microprocessor such as a CPU and its peripheral circuits, and reads and executes the program 240P from the storage unit 240, thereby realizing the various processing units by cooperating the hardware and the program 240P. have. The main processing units realized by the processor 250 include a usage history management unit 250A, a connection relationship generation unit 250B, and a communication facility management unit 250C.

  The usage history management unit 250 </ b> A inputs the usage history of services provided from the computer system 120 to the terminal device 110 from the communication I / F unit 210 or the operation input unit 220, and uses the terminal device in the usage history 240 </ b> A of the storage unit 240. 110 has a function of accumulating separately.

  The connection relationship generation unit 250B has a function of monitoring the movement of the terminal device 110, and a function of generating connection relationship data 240B on the storage unit 240 based on the monitoring result, and maintaining (updating) it in the latest state. Have.

  The communication facility management unit 250C has a function of predicting the traffic amount for each local communication network 140, and a function of calculating an insufficient amount and an excess amount of the communication facility capacity of the local communication network 140 based on the predicted traffic amount.

  Next, the operation of this embodiment will be described.

  The usage history management unit 250A, from the communication I / F unit 210 or the operation input unit 220, identifies the identifier of the terminal device 110 that used the service, the date and time of use, the identifier of the computer system 120 that provided the service, the type of service used, and the service Use of data by using the amount of data transmitted and received between the terminal device and the computer system when using the service, the identifier of the local communication network 140 to which the terminal device 110 was connected when using the service, and other information as one set Enter the history. The usage history management unit 250A searches the storage unit 240 for the usage history file 240A1 of FIG. 3 using the input identifier of the terminal device 110 in the set as a key, and uses the remaining data in the set as one history data 240A3. Add to history file 240A1. The usage history management unit 250A repeats the same process every time a set of service usage history is input.

  On the other hand, the connection relationship generation unit 250B executes the process shown in FIG. 9 every time a predetermined time period elapses or every time an activation instruction is input from the communication I / F unit 210 or the operation input unit 220. . First, the connection relationship generation unit 250B reads the connection relationship data 240B shown in FIG. 4 or 5 from the storage unit 240, and pays attention to one terminal device 110 in the first row (S101). Next, the connection relationship generation unit 250B detects the current position of the terminal device 110 of interest using a method similar to the method described in the first embodiment, and is currently connected or connected. The local communication network 140 that may be present is determined (S102). Next, the determined local communication network 140 is compared with the connection destination described in the connection relation data 240B. If the two are different, it is determined that the terminal device 110 of interest has moved between the local communication networks. If both are the same, it is determined that there is no movement (S103).

  Next, when it is determined that the terminal device 110 under attention has moved between local communication networks (YES in S103), the connection relationship generation unit 250B updates the connection relationship data 240B (S104). Specifically, in the case of the connection relation data 240B of FIG. 4, the logical value 1 described in the line having the identifier of the terminal device 110 under attention is rewritten to the logical value 0, and the line and the above-described step S102 are determined. The logical value 0 described at the intersection with the column having the identifier of the destination local communication network 140 is rewritten to the logical value 1. Further, in the case of the connection relation data 240B of FIG. 5, the logical value 1 described in the row having the identifier of the terminal device 110 under attention is rewritten to the logical value 0, and the logical value 0 is assigned to the rewritten column. The logic of the local communication network is overwritten with the connection history column in the same row, and the logic described at the intersection of the row and the column having the identifier of the destination local communication network 140 determined in step S102 above. Rewrite the value 0 to the logical value 1. Next, the connection relationship generation unit 250B increments the value of an internal variable (the initial value is 0) representing the number of mobile terminals by 1 (step S105). Then, the process proceeds to step S106.

  If the connection relationship generator 250B determines that the terminal device 110 under attention has not moved between the local communication networks (NO in S103), it skips steps S104 and S105, and proceeds to step S106.

  In step S106, the connection relationship generation unit 250B shifts attention to one terminal device 110 in the next row of the connection relationship data 240B. And it returns to step S102 via step S107, and repeats the process similar to the process performed with respect to the terminal device 110 noticed previously. On the other hand, if attention has been paid to the terminal device 110 in the last row of the connection relation data 240B (YES in S107), it is checked whether or not the number of mobile terminals indicated by the internal variable exceeds the threshold (S108). The threshold value is set to an arbitrary value of 1 or more. If the number of mobile terminals does not exceed the threshold value (NO in S108), the process in FIG. 9 ends. On the other hand, if the number of mobile terminals exceeds the threshold (YES in S108), the communication facility management unit 250C is activated (S109), the number of mobile terminals is initialized to 0 (S110), and the process of FIG.

  When activated, the communication facility management unit 250C executes the process shown in FIG.

  First, the communication facility management unit 250C generates a usage history (prediction usage history) used for prediction from the usage history 240A stored in the storage unit 240 (S121). Details of the method of generating the prediction usage history will be described later.

  Next, the communication facility management unit 250C pays attention to one local communication network 140 (S122). Next, the communication facility management unit 250C extracts a usage history related to a service passing through the local communication network 140 of interest from the prediction usage history (S123). Specifically, the identifier of the local communication network 140 under attention is described in the connection destination local communication network identifier 240A8, or the identifier of the computer system 120 connected to the local communication network 140 under attention is the computer system. The history data 240A3 described in the identifier 240A6 is extracted from the use history for prediction. The computer system 120 connected to the local communication network 140 of interest is determined with reference to the computer system facility information 240E shown in FIG.

  Next, using the history data extracted in step S123, a graph of the traffic volume of the local communication network 140 of interest is created (S124). FIG. 11 shows an example of the created graph. In this example, the elapsed time from the current time is plotted on the horizontal axis, the amount of data per unit time and the number of simultaneous connections are plotted on the vertical axis, and the time change in the amount of data flowing through the local communication network 140 and the number of simultaneous connections is represented by a line graph. ing.

  Next, the communication facility management unit 250C calculates the shortage and excess of the communication facility capacity of the local communication network 140 under attention using the created graph (S125). Specifically, the maximum bandwidth and the maximum number of simultaneous connections as the communication facility capacity of the local communication network 140 of interest are read from the communication facility capacity information 240D stored in the storage unit 240, as shown in FIG. Display on graph. If the data amount exceeds the maximum bandwidth at any time, the portion of the data amount at each time that exceeds the maximum bandwidth is set as a bandwidth shortage amount. Further, when the number of simultaneous connections exceeds the maximum number of simultaneous connections at any time, a portion exceeding the maximum number of simultaneous connections among the number of simultaneous connections at each time is set as an insufficient amount of connections. Further, when the data amount does not exceed the maximum bandwidth at any time, the difference between the maximum value of the data amount and the maximum bandwidth is set as the excess amount of the bandwidth. Further, if the number of simultaneous connections does not exceed the maximum number of simultaneous connections at any time, the difference between the maximum value of the number of simultaneous connections and the maximum number of simultaneous connections is determined as the excess number of connections.

  Next, the communication facility management unit 250C shifts attention to the next one local communication network 140 (S126), and repeats the same processing as the processing performed on the local communication network 140 that has been noted earlier (S123 to S125). . When attention is paid to all local communication networks 140 (YES in S127), the shortage and excess of the communication facility capacity for each local communication network are displayed on screen display unit 230, or from communication I / F unit 210. Output (S128).

  The shortage amount of the communication facility capacity for each local communication network may be output in a graph format as shown in FIG. In the graph of FIG. 13, the portion of the data amount at each time exceeding the maximum bandwidth and the portion of the number of simultaneous connections at each time exceeding the maximum number of simultaneous connections are respectively hatched, and the insufficient amount of bandwidth and the number of connections. The amount of deficiency is easily recognized visually. Alternatively, from the graph shown in FIG. 12, the data such as the period when the data amount exceeds the maximum bandwidth, the excess amount, etc. as the insufficient amount of the bandwidth, and the data such as the period when the number of simultaneous connections exceeds the maximum simultaneous connection number, the excess number, It may be obtained as a shortage amount of connections and output in text format.

  The excess amount of communication equipment capacity for each local communication network may be output in a graph format as shown in FIG. In the graph of FIG. 14, the difference between the maximum amount of data and the maximum bandwidth and the difference between the maximum number of simultaneous connections and the maximum number of simultaneous connections are respectively hatched, and the excess amount of bandwidth and the number of connections are shown. The amount of excess is easily recognized visually. Alternatively, from the graph shown in FIG. 12, data such as the minimum value of the difference between the data amount and the maximum bandwidth is obtained as an excess amount of the bandwidth, and data such as the minimum value of the difference between the number of simultaneous connections and the maximum number of simultaneous connections is obtained. It may be obtained as an excessive amount of connections and output in text format.

  Next, details of step S121 for generating a usage history for prediction from the usage history 240A will be described.

As described in the first embodiment, the pattern in which the terminal device 110 uses the service (the tendency of the type and frequency of the service to be used) is generally fixed for each terminal device 110. As the type to be fixed, for example, there are several types as follows.
(1) 1st type This type is a case where the same service utilization pattern is repeated periodically. For example, a service pattern similar to the previous day may be repeated, or a service usage pattern similar to the same day of the week may be repeated.
(2) Second type This type is a case where a unique service usage pattern exists for each connected local communication network. For example, when connected to a certain local communication network, there is a tendency to frequently use a certain type of service. However, when connected to another local communication network, another type of service is used. This is the case of using a lot.
(3) Third type This type is a case where a service usage pattern similar to that of the local communication network connected immediately before is repeated. For example, if a certain type of service is frequently used in the local communication network connected immediately before, the same type of service is frequently used also in the new local communication network after movement. It is.

  The type to which each terminal device 110 belongs may be determined in advance, or may be dynamically calculated by analyzing the usage history 240A.

  First, a prediction usage history generation method suitable for the case where all the terminal devices 110 belong to the first type will be described with reference to the flowchart of FIG.

  First, the communication facility management unit 250C predicts a usage history in which the date and time before the first period from the current date and time is the beginning, and after the second period has elapsed from the beginning and the usage date and time 240A4 is within the period from the beginning to the end. The usage history is extracted from the usage history 240A (S141). Next, the communication facility management unit 250C advances the use date and time 240A4 in the history data 240A3 in the extracted use history for prediction for the first period (S142). The first and second periods are arbitrary. For example, assuming that the first period is one week and the second period is one day, it is possible to make a prediction for one day ahead using the use history of the same day of the previous week. The first period may be one day, one month, one year, etc., not one week ago, and the second period is not one day, one week, one month, one year, etc. May be.

  Next, the communication facility management unit 250C compares the connection destination local communication network identifier 240A8 in the history data 240A3 in the use history for prediction with the current connection destination specified by the connection relation data 240B stored in the storage unit 240. If they are different, the current connection destination is changed (S143). And the production | generation process of the utilization history for prediction is complete | finished.

  Next, a method for generating a use history for prediction suitable when all the terminal devices 110 belong to the second type will be described with reference to the flowchart of FIG.

  First, the communication facility management unit 250C pays attention to one terminal device 110 (S151). Next, from the usage history file 240A1 of the terminal device 110 under attention, the history data 240A3 in which the connection destination specified by the connection relation data 240B is described in the connection destination local communication network identifier 240A8 is predicted for the first period. It is extracted as a usage history (S152). The first period is, for example, 1 hour, 1 day, 1 week, 1 month, or the like. When the corresponding history data 240A3 exists for the first period or more, it may be extracted from the more recent data. If the corresponding history data 240A3 does not exist for the first period, the existing period data may be extracted, and the missing period may be created by copying the history data of the existing period. In addition, when there is no corresponding history data 240A3, predetermined standard history data may be used.

  Next, the communication facility management unit 250C shifts the use date and time 240A4 in the history data 240A3 of the prediction use history for the extracted first period so as to be the date and time during the prediction period (step S153).

  Next, the communication facility management unit 250C shifts attention to the next one terminal device 110 (S154), and repeats the same processing as the processing performed on the terminal device 110 focused on first (S152, S153). When attention is paid to all the terminal devices 110 (YES in S155), the generation process of the prediction use history is ended.

  Next, a method for generating a use history for prediction suitable when all the terminal devices 110 belong to the third type will be described with reference to the flowchart of FIG.

  First, the communication facility management unit 250C pays attention to one terminal device 110 (S161). Next, the connection destination (local communication network connected immediately before) specified by the connection history of the connection relation data 240B is described in the connection destination local communication network identifier 240A8 from the usage history file 240A1 of the terminal device 110 under attention. The recorded history data 240A3 is extracted as the use history for prediction for the first period (S162). The first period is, for example, 1 hour, 1 day, 1 week, 1 month, or the like. When the corresponding history data 240A3 exists for the first period or more, it may be extracted from the more recent data. If the corresponding history data 240A3 does not exist for the first period, the existing period data may be extracted, and the missing period may be created by copying the history data of the existing period. In addition, when there is no corresponding history data 240A3, predetermined standard history data may be used.

  Next, the communication facility management unit 250C shifts the use date and time 240A4 in the history data 240A3 of the predicted use history for the extracted first period so as to be the date and time during the prediction period (step S163).

  Next, the communication facility management unit 250C is the current connection destination identified by the connection relation data 240B stored in the storage unit 240, with respect to the connection destination local communication network identifier 240A8 in the history data 240A3 in the use history for prediction. The local communication network is changed (S164).

  Next, the communication facility management unit 250C shifts attention to the next one terminal device 110 (S165), and repeats the same processing as the processing performed on the terminal device 110 that has been noted earlier (S162 to S164). When attention is paid to all the terminal devices 110 (YES in S166), the prediction use history generation process is terminated.

  In the above description, it is assumed that all the terminal devices 110 belong to the same type, but cases where the types belonging to each terminal device 110 are different are also conceivable. In that case, the usage history 240A is classified by type, and the usage history for prediction for the terminal device 110 belonging to the first type is generated by the method shown in FIG. 15, and the usage history of the terminal device 110 belonging to the second type is determined. 16 is generated by the method shown in FIG. 16, and the usage history for prediction for the terminal device 110 belonging to the third type is generated by the method shown in FIG. What is necessary is just a use history for prediction.

  According to this embodiment, the same effects as those of the first embodiment can be obtained, and the following effects can be obtained.

  Not only the shortage amount of communication equipment for each local communication network but also the excess amount can be predicted in advance. Thus, since the excess amount of the communication equipment capacity of the local communication network 140 can be predicted in advance, the work of reducing the communication equipment capacity can be started at an early stage, and the long-term retention of surplus resources can be prevented.

  According to the configuration in which the traffic amount for each local communication network is predicted based on the same day of the week and time zone usage history as when the prediction is made, accurate prediction can be performed when the same service usage pattern is periodically repeated.

  According to the configuration that predicts the traffic volume for each local communication network based on the usage history of the same place as the prediction time, accurate prediction is possible when the usage pattern of the service used there is fixed for each local communication network Yes.

  According to the configuration that predicts the traffic volume for each local communication network based on the usage history of the location that existed immediately before, it is accurate when the same service usage pattern as the local communication network connected immediately before is repeated. Predictions can be made.

The maximum number of simultaneous connections and the maximum data transfer rate are calculated and displayed on a graph as shown in FIG. If the data amount exceeds the maximum data transfer rate at any time, the portion of the data amount at each time that exceeds the maximum data transfer rate is set as an insufficient amount of data transfer rate. Further, when the number of simultaneous connections exceeds the maximum number of simultaneous connections at any time, a portion exceeding the maximum number of simultaneous connections among the number of simultaneous connections at each time is set as an insufficient amount of connections. Further, when the data amount does not exceed the maximum data transfer rate at any time, the difference between the maximum value of the data amount and the maximum data transfer rate is set as the excess amount of the data transfer rate. Further, if the number of simultaneous connections does not exceed the maximum number of simultaneous connections at any time, the difference between the maximum value of the number of simultaneous connections and the maximum number of simultaneous connections is determined as the excess number of connections.

  Next, the computer system facility management unit 350D shifts attention to the next one local communication network 140 (S206), and repeats the same processing as the processing performed on the local communication network 140 that has been focused on first (S203 to S205). ).

(S208).

  The shortage of computer system facility capacity for each local communication network may be output in a graph format as shown in FIG.

Alternatively, from the graph shown in FIG. 22, data such as a period when the data amount exceeds the maximum data transfer rate, data such as an excess amount is obtained as an insufficient amount of transfer rate, and a period when the number of simultaneous connections exceeds the maximum number of simultaneous connections, the number of excess May be obtained as an insufficient amount of connections and output in text format.

  The excess computer system facility capacity for each local communication network may be output in a graph format as shown in FIG. In the graph of FIG. 24, the difference between the maximum amount of data and the maximum transfer rate and the difference between the maximum number of simultaneous connections and the maximum number of simultaneous connections are respectively hatched, and the excess transfer rate This makes it easy to visually recognize the excessive number of connections. Alternatively, from the graph shown in FIG. 22, data such as the minimum value of the difference between the data amount and the maximum transfer rate is obtained as an excess amount of the transfer rate, and the minimum value of the difference between the number of simultaneous connections and the maximum number of simultaneous connections is determined. Data may be obtained as an excessive number of connections and output in text format.

  According to this embodiment, the same effects as those of the second embodiment can be obtained, and the provision of services to the terminal device 110 can be performed from the computer system 120 connected to the local communication network 140 to which the terminal device 110 is connected.

  The communication facility increasing unit 450E and the communication facility reducing unit 450F are activated after the processing of the communication facility management unit 450C is completed.

  FIG. 26 is a flowchart illustrating a processing example of the communication facility increasing unit 450E. First, the communication facility increasing unit 450E acquires the shortage amount of the communication facility capacity for each local communication network 140 from the communication facility management unit 450C (S301). Next, the communication facility increasing unit 450E pays attention to one local communication network in which the communication facility capacity is insufficient (S302). If there is no local communication network 140 with insufficient communication equipment capacity (YES in S303), the process is terminated. If there is, the communication facility increasing unit 450E pays attention to each local communication network 140 for which the communication facility capacity is insufficient, and executes the following processing.

  First, the communication facility increase unit 450E determines an increase amount commensurate with the shortage amount of the local communication network 140 under attention (S304). For example, when the bandwidth is insufficient, an amount obtained by adding a predetermined amount (a certain amount or a certain ratio of the insufficient bandwidth) to the insufficient bandwidth is set as the increase amount. When the number of simultaneous connections is insufficient, an amount obtained by adding a predetermined number (a fixed number or a fixed ratio of the number of insufficient connections) to the number of insufficient connections is set as an increase amount. Next, the communication equipment increasing unit 450E increases the communication equipment capacity of the local communication network 140 under attention by the determined increase amount (S305). Then, the communication facility increasing unit 450E shifts attention to the next one local communication network in which the communication facility capacity is insufficient (S306), returns to step S303, and repeats the same processing as described above.

  A specific example of the communication facility capacity increasing method implemented in step S305 will be described below. As a technique for realizing various communication networks, there is a virtual communication network technique for constructing a plurality of logical communication networks using a physical communication network (see, for example, Patent Document 3). In such a virtual communication network technology, a virtual communication network having a desired bandwidth, the number of lines, etc. can be generated by designating a band or the like when generating a virtual communication network on a physical communication network. . Therefore, as one method for increasing the communication facility capacity of the local communication network 140, the local communication network 140 is realized by a virtual communication network. And the communication equipment increase part 450E increases the communication equipment capacity of the local communication network 140 as a virtual communication network using a virtual communication network technique. At this time, the communication equipment increasing unit 450E acquires free network resources from the same physical communication network as the physical communication network that initially generated the local communication network 140, and newly secures the increased communication equipment capacity. Also good. Alternatively, the communication facility increasing unit 450E may use different physical communication from the physical communication network that initially generated the local communication network 140 if there is a special situation such as the physical communication network that initially generated the local communication network 140 has no free resources. It is also possible to allow free network resources to be accommodated from the network and to newly secure an increased communication facility capacity by using the accommodated network resources.

  FIG. 27 is a flowchart illustrating a processing example of the communication facility reduction unit 450F. First, the communication facility reduction unit 450F acquires an excessive amount of communication facility capacity for each local communication network 140 from the communication facility management unit 450C (S311). Next, the communication facility reduction unit 450F pays attention to one local communication network having an excessive communication facility capacity (S312). If there is no local communication network 140 having an excessive communication facility capacity (YES in S313), the process is terminated. If there is, the communication facility reduction unit 450F pays attention to each local communication network 140 having an excessive communication facility capacity and executes the following processing.

  First, the communication facility reduction unit 450F determines a reduction amount commensurate with the excess amount of the local communication network 140 under attention (S314). For example, when the bandwidth is excessive, an amount obtained by subtracting a predetermined amount (a constant amount or a constant ratio of the excess amount) from the excess amount is set as the reduction amount. When the number of simultaneous connections is excessive, an amount obtained by subtracting a predetermined number (a fixed number or a fixed ratio of the excessive number) from the excess number is set as a reduction amount. Next, the communication facility reduction unit 450F reduces the communication facility capacity of the local communication network 140 under attention by the determined reduction amount (S315). Then, the communication facility reduction unit 450F shifts the attention to the next one local communication network having an excessive communication facility capacity (S316), returns to step S313, and repeats the same processing as described above.

  A specific example of the communication facility capacity reduction method implemented in step S315 will be described below. For example, when the local communication network 140 is a virtual communication network, the communication facility reduction unit 450F reduces the communication facility capacity of the local communication network 140 using virtual communication network technology. At this time, the communication facility reduction unit 450F returns the reduced communication facility capacity to the physical communication network that secures the communication facility capacity. That is, the communication facility reduction unit 450F reduces the amount of the communication facility capacity with respect to the initially generated physical communication network if the communication facility capacity for the reduction uses the network resources of the physical communication network that initially generated the local communication network 140. Return the network resources used by the communication equipment capacity. Further, if the communication equipment capacity of the reduced communication equipment capacity uses a network resource of a physical communication network different from the physical communication network that initially generated the local communication network 140, the communication equipment reduction unit 450F uses the different physical communication network. In contrast, the network resources used by the reduced communication facility capacity are returned.

  On the other hand, the computer system equipment increase unit 450G and the computer system equipment reduction unit 450H are activated after the processing of the computer system equipment management unit 450D is completed.

  FIG. 28 is a flowchart showing a processing example of the computer system facility increasing unit 450G. First, the computer system equipment increase unit 450G acquires the shortage of the computer system equipment capacity for each local communication network 140 from the computer system equipment management unit 450D (S321). Next, the computer system equipment increase unit 450G pays attention to one local communication network whose computer system equipment capacity is insufficient (S322). If there is no local communication network 140 with insufficient computer system capacity, the process is terminated. If it exists, the computer system equipment increase unit 450G performs the following processing, paying attention to each local communication network 140 in which the computer system equipment capacity is insufficient.

  First, the computer system facility increase unit 450G determines an increase amount corresponding to the shortage amount of the local communication network 140 under attention (S324). For example, when the maximum data transfer rate is insufficient, an amount obtained by adding a predetermined amount (a fixed amount or a fixed ratio of the insufficient data transfer rate) to the insufficient data transfer rate is set as the increase amount. When the maximum number of simultaneous connections is insufficient, an amount obtained by adding a predetermined number (a fixed number or a fixed ratio of the number of insufficient connections) to the number of insufficient connections is set as the increase amount. Next, the computer system facility increase unit 450G increases the computer system facility capacity of the local communication network 140 under attention by the determined increase amount (S325). Then, the computer system equipment increase unit 450G shifts attention to the next one local communication network in which the computer system equipment capacity is insufficient (S326), returns to step S323, and repeats the same processing as described above.

  The increase in the computer system facility capacity performed in step S335 will be described in detail. As a technology for realizing a computer system configured by various server devices and storage devices, there is a virtual computer technology for constructing a plurality of logical computer systems using a physical computer system. As a product to which this kind of technology is applied, “VMWare ESX Server” by VMware, “VirtualServer” by Microsoft, and “Xen” by XenSource in the United States are known. In these products, a new virtual computer system can be generated on the physical computer system by issuing a command for generating a virtual computer. In such a virtual computer technology, a virtual computer system having a desired maximum data transfer rate, maximum number of simultaneous connections, and the like can be generated by designating processing capacity when generating the virtual computer system. Therefore, the computer system 120 is realized by a virtual computer system as one method for expanding the computer system facility capacity of the local communication network 140. Then, the computer system facility increase unit 450G increases the processing capacity of the computer system 120 as a virtual computer system connected to the local communication network 140 using the virtual computer technology. At this time, the computer system facility increase unit 450G acquires a free computer resource from the same physical computer system as the physical computer system that initially generated the computer system 120, and expands the processing capacity of the existing virtual computer system. By adding a new virtual computer system, it is possible to newly secure the increased computer system capacity. Alternatively, if there is a special event such as the physical computer system in which the computer system 120 is initially generated has no free computer resources, the computer system facility increase unit 450G has a different physicality from that of the physical computer system in which the computer system 120 is initially generated. A computer system, which acquires free computer resources from a physical computer system connected to the same local communication network 140 as the initially generated computer system 120, and uses the acquired computer resources to increase the computer system You may make it ensure newly installation capacity.

  FIG. 29 is a flowchart showing a processing example of the computer system equipment reduction unit 450H. First, the computer system equipment reduction unit 450H acquires an excessive amount of computer system equipment capacity for each local communication network 140 from the computer system equipment management unit 450D (S331). Next, the computer system equipment reduction unit 450H pays attention to one local communication network having an excessive computer system equipment capacity (S332). If there is no local communication network 140 having an excessive computer system facility capacity (YES in S333), the process is terminated. If it exists, the computer system equipment reduction unit 450H performs the following processing by paying attention to each local communication network 140 having an excessive computer system equipment capacity.

  First, the computer system equipment reduction unit 450H determines a reduction amount commensurate with the excessive amount of the local communication network 140 under attention (S334). For example, when the maximum data transfer rate is excessive, an amount obtained by subtracting a predetermined amount (a constant amount or a constant ratio of the excessive amount) from the excessive amount is set as the reduction amount. When the maximum number of simultaneous connections is excessive, an amount obtained by subtracting a predetermined number (a fixed number or a fixed ratio of the excessive number) from the excess number is set as a reduction amount. Next, the computer system equipment reduction unit 450H reduces the computer system equipment capacity of the local communication network 140 under attention by the determined reduction amount (S335). Then, the computer system equipment reduction unit 450H shifts attention to the next one local communication network having an excessive computer system equipment capacity (S336), returns to step S333, and repeats the same processing as described above.

  A specific example of the computer system facility capacity reduction method implemented in step S335 will be described below. For example, when the computer system 120 is a virtual computer system, the computer system facility reduction unit 450H reduces the computer system facility capacity of the local communication network 140 using virtual computer technology. At this time, the computer system equipment reduction unit 450H acquires the computer resources used by the reduced computer system equipment capacity and returns them to the physical computer system. That is, if the computer system facility capacity for the reduced amount uses the computer resources of the physical computer system that initially generated the computer system 120, the computer system facility reduction unit 450H may Return the computer resources used by the reduced computer system capacity. The computer system facility reduction unit 450H uses a resource of a physical computer system that is different from the physical computer system that initially generated the computer system 120 in terms of the reduced computer system facility capacity. On the other hand, the computer resources used by the reduced computer system capacity are returned.

  According to this embodiment, the same effects as those of the fourth embodiment can be obtained, and the following effects can be obtained.

  Communication equipment capacity increase / reduction corresponding to the shortage or excess of the communication system capacity for each local communication network 140 caused by the movement of the terminal device 110, or the shortage or excess of the computer system capacity. The system capacity can be increased or decreased automatically.

  Since the computer system 120 connected to the same local communication network 140 can provide a service to the terminal device 110, a necessary and sufficient computer system facility capacity can be secured for each local communication network 140, so that the terminal device 110 is relayed. A situation in which a service is provided from a remote computer system 120 via the network 150 can be avoided. As a result, the access between the terminal device 110 and the computer system 120 is performed within the local communication network 140 and does not go through the relay network 150, thereby reducing the amount of wasted traffic and suppressing or mitigating the occurrence of a large amount of traffic. be able to. In addition, since provision of services to the terminal device 110 is distributed processing performed from the computer system 120 connected to the same local communication network 140, a large amount of data is concentrated in a specific computer system 120 spatially and temporally. It is possible to suppress or alleviate the occurrence of large amounts of data.
