Description

  The present invention relates to a calculation device, a network system, a calculation method, and a calculation program.

  In general, ISPs (Internet Services Providers) that provide Internet connection services often provide mail services that relay electronic mail sent and received between users. For example, the ISP receives an e-mail from a user terminal, and when the user terminal that is the destination of the e-mail is connected to the local communication network, the ISP transmits the e-mail to the user terminal, If the user terminal is not connected to the own communication network, an electronic mail is transmitted via another ISP.

  Such e-mails include e-mails called “junk mails” and “spam mails”. Junk mail is often sent to an unspecified number by malicious mail senders, and often damages mail recipients. For example, spam mail may contaminate a mail recipient's user terminal with a computer virus.

  Thus, some ISPs are taking measures against spam mails. Specifically, when an ISP taking measures against junk mail transmits an e-mail received from a user terminal or another ISP to a destination user terminal, whether the e-mail is junk mail or not. And send an e-mail that is not a junk mail to the user terminal. As a result, the ISP can improve the service of the mail service.

  However, even if some ISPs take measures against spam mails, there are ISPs that relay spam mails, and there is a problem that many spam mails are distributed between ISPs. Specifically, since a malicious ISP can collect a usage fee from a malicious user, it may not take measures against spam mail. If such a malicious ISP exists, many spam mails are distributed to ISPs that take measures against spam mails.

  In the above description, e-mail is taken as an example of data distributed between ISPs, and a problem that many spam mails circulate between ISPs has been described. However, such problems also occur in addition to spam mails. Specifically, various data such as moving image data and image data other than e-mail are distributed between ISPs, but there is a problem that a lot of unnecessary data unnecessary for both ISPs is distributed between ISPs. .

  The present invention has been made in view of the above, and an object thereof is to provide a calculation device, a network system, a calculation method, and a calculation program that can reduce the amount of unnecessary data distributed between ISPs.

In one aspect, an embodiment of the present invention is a calculation device for calculating a billing amount imposed between a first provider that provides an Internet connection service and a second provider. Of e-mails sent and received between a first communication network provided by a provider and a second communication network provided by the second provider, the first provider and the second provider The connection form between the first communication network and the second communication network is peering, and the calculation unit that calculates the number of spam mails that are e-mails that are determined to be unnecessary between the first communication network and the second communication network is peering. In this case, the larger the number of received junk mails calculated by the calculating unit, the higher the amount charged by the first provider to the second provider. The greater the number of spam mails sent by the first provider calculated by the calculation unit, the higher the amount charged by the second provider for the first provider, and the first communication network and the first provider. The connection form with the second communication network is transit, and the first provider uses the second provider to charge a billing amount that is a connection fee for connection between the first communication network and the second communication network. In the case of charging, the increase / decrease is based on the difference between the number of spam mails received by the first provider calculated by the calculation unit and the number of spam mails transmitted by the first provider calculated by the calculation unit. And a calculating unit for calculating the charged amount .

  The calculation device, network system, calculation method, and calculation program according to the present invention have an effect that the amount of unnecessary data distributed between ISPs can be reduced.

  Hereinafter, embodiments of a calculation device, a network system, a calculation method, and a calculation program according to the present invention will be described in detail with reference to the drawings. In addition, this invention is not limited by this Example.

[Configuration of Network System According to Embodiment 1]
First, the network system according to the first embodiment will be described with reference to FIG. FIG. 1 is a diagram illustrating a configuration example of a network system 1 according to the first embodiment. In the example shown in FIG. 1, the network system 1 includes communication networks 10-1 to 10-6.

  Each of the communication networks 10-1 to 10-6 is provided by a different ISP. For example, the ISP that provides the communication network 10-1 is different from the ISP that provides the communication networks 10-2 to 10-6, and the ISP that provides the communication network 10-2 is the communication networks 10-1 and 10-3. Different from each ISP providing -10-6. In the following, the ISP that provides the “communication network 10-n” may be referred to as “ISP10p-n”. For example, an ISP that provides the communication network 10-1 may be referred to as “ISP10p-1”, and an ISP that provides the communication network 10-2 may be referred to as “ISP10p-2”.

  In the network system 1 illustrated in FIG. 1, two communication networks are connected by peering or transit. In FIG. 1, two communication networks connected by a straight line with squares at both ends are connected by peering, and two communication networks connected by a straight line with black circles at one end are connected by transit. Indicates. In the first embodiment, when the connection form is peering, no connection fee is charged between both ISPs. When the connection form is transit, one ISP periodically charges a connection fee to the other ISP. At this time, in the example shown in FIG. 1, the ISP of the communication network connected to one end of the straight line to which the black circle is given is connected to the ISP of the communication network connected to the other end of the straight line to which the black circle is not given. Shall be charged.

  For example, the communication network 10-1 and the communication network 10-4 are interconnected by peering, and the ISP 10p-1 of the communication network 10-1 and the ISP 10p-4 of the communication network 10-4 charge a connection fee with each other. Do not charge. The communication network 10-1 and the communication network 10-2 are connected by transit, and the ISP 10p-1 of the communication network 10-1 periodically charges a connection fee to the ISP 10p-2 of the communication network 10-2. Charge. In other words, the ISP 10p-2 periodically pays a connection fee to the ISP 10p-1. Further, the communication network 10-2 and the communication network 10-3 are connected by transit, and the ISP 10p-2 periodically charges the ISP 10p-3 for a connection fee.

  Although not shown in FIG. 1, it is assumed that the communication networks 10-3 and 10-6 are connected to a user terminal that uses the Internet service. That is, in the example shown in FIG. 1, it is assumed that the ISPs 10p-3 and 10p-6 do not charge connection fees to other ISPs.

  Here, between the communication networks illustrated in FIG. 1, unnecessary data that is unnecessary for each ISP providing each communication network may be distributed. The “unnecessary data” referred to here is data previously contracted between both ISPs connected to the communication network. For example, it is unnecessary for e-mail called spam mail or both ISPs. Moving image data, image data, and the like.

  In the network system 1 according to the first embodiment, when unnecessary data circulates between communication networks connected to each other, one ISP separates the other ISP from the connection fee according to the amount of unnecessary data. Charge a predetermined fee (hereinafter sometimes referred to as “additional fee”). Specifically, when a communication network provided by one ISP receives unnecessary data from a communication network provided by the other ISP, one ISP increases the additional charge as the amount of such unnecessary data increases. Calculate and charge the calculated additional fee to the other ISP.

  Hereinafter, the charging of the additional fee will be specifically described together with the description of each device included in the communication network 10-1 or the like. Since the communication networks 10-1, 10-2, 10-4, and 10-5 have the same configuration, the communication network 10-1 will be mainly described here.

  As illustrated in FIG. 1, the communication network 10-1 includes a service providing device 11-1, a charging device 12-1, and a calculation device 100-1. The service providing apparatus 11-1 is a server that provides various services, and provides an Internet connection service, a relay service that relays various data such as electronic mail, and the like. For example, the service providing apparatus 11-1 transmits / receives an electronic mail to / from the service providing apparatus 11-2 in the communication network 10-2, or between the service providing apparatus 11-4 in the communication network 10-4. To send and receive e-mails.

  The unnecessary data in the first embodiment indicates unnecessary data among data transmitted and received between ISPs. For example, an ISP that performs a relay process accepts such unnecessary data from another ISP or a user terminal. Also included is data that is sent to adjacent ISPs. That is, the unnecessary data received by one ISP from the other ISP includes even the relayed unnecessary data, and the unnecessary data transmitted from one ISP to the other ISP includes the relayed unnecessary data. It is.

  The charging device 12-1 charges an ISP that provides another communication network connected to the communication network 10-1 every predetermined period (for example, one month). In the example shown in FIG. 1, since the communication network 10-1 and the communication network 10-4 are connected by peering, the billing apparatus 12-1 is connected to the ISP 10p-4 that provides the communication network 10-4. No connection fee is charged. However, the charging device 12-1 in the first embodiment charges the ISP 10p-4 with the additional fee calculated by the calculating device 100-1 separately from the connection fee. For example, the charging device 12-1 notifies the charging device 12-4 in the communication network 10-4 of the information indicating the charging amount by using the additional fee calculated by the calculating device 100-1 as the charging amount. Charge the ISP 10p-4 for the charge amount. The additional charge calculation process performed by the calculation apparatus 100-1 will be described later.

  In the example shown in FIG. 1, since the communication network 10-1 and the communication network 10-2 are connected by transit, the charging device 12-1 is connected to the ISP 10p-2 that provides the communication network 10-2. The connection fee is charged. Specifically, the charging device 12-1 calculates a connection fee based on the amount of data transmitted / received between the communication network 10-1 and the communication network 10-2. Further, the charging device 12-1 in the first embodiment charges the ISP 10p-2 with the additional fee calculated by the calculating device 100-1 in addition to the connection fee. For example, the billing device 12-1 adds or subtracts the additional fee calculated by the calculation device 100-1 to the connection fee, and uses the fee after the addition or subtraction as the billing amount, and shows information indicating the billing amount as a communication network. By notifying the billing device 12-2 in 10-2, the billing amount is billed to the ISP 10p-2.

  The calculation device 100-1 calculates an additional fee based on unnecessary data transmitted and received between the communication network 10-1 and another communication network every predetermined period (for example, one month), and calculates the added The charge device 12-1 is notified of the additional charge information indicating the charge.

  Specifically, when the communication network 10-1 is connected to another communication network by peering, the calculation device 100-1 in the first embodiment receives the communication network 10-1 from the other communication network. Based on the amount of unnecessary data, an additional fee charged by the ISP 10p-1 to an ISP providing another communication network is calculated. At this time, the calculation device 100-1 calculates a higher additional charge as the amount of unnecessary data received by the communication network 10-1 increases.

  The reason for calculating the additional charge will be described. When the unnecessary data is received from the other communication network, the communication network 10-1 is considered to be damaged by the other communication network. And it is thought that the damage which the communication network 10-1 receives becomes so large that many unnecessary data are received from another communication network. Therefore, as the amount of unnecessary data received by the communication network 10-1 from the other communication network increases, the calculation device 100-1 increases the amount of unnecessary data as a compensation for the damage received by the communication network 10-1 from the other communication network. The additional fee charged to the ISP that provides the communication network is calculated high.

  In the example shown in FIG. 1, the communication network 10-1 and the communication network 10-4 are connected by peering. Accordingly, the calculation device 100-1 calculates the additional fee that the ISP 10p-4 pays to the ISP 10p-1 as the amount of unnecessary data received by the communication network 10-1 from the communication network 10-4 increases.

  Further, when the communication network 10-1 is connected to another communication network by a transit, the calculation device 100-1 is based on the amount of unnecessary data received from the other communication network by the communication network 10-1. In addition to calculating the additional fee that the other ISP pays to the ISP 10p-1, the ISP 10p-1 pays the additional fee that the ISP 10p-1 pays to the other ISP based on the amount of unnecessary data transmitted to the other communication network. Calculate. At this time, as the amount of unnecessary data received by the communication network 10-1 increases, the calculation device 100-1 calculates a higher additional fee paid by the other ISP to the ISP 10p-1, and the communication network 10-1 transmits the additional fee. The larger the amount of unnecessary data, the higher the additional fee paid by ISP 10p-1 to other ISPs.

  The reason for calculating the additional charge in this way will be described. As described above, when the communication network 10-1 receives unnecessary data from another communication network, it is considered that the communication network 10-1 is damaged by the other communication network. It is done. Therefore, in the same way as described above, the calculation device 100-1 uses the amount of unnecessary data received by the communication network 10-1 from the other communication network as a compensation for the damage received by the communication network 10-1 from the other communication network. As the number increases, the additional fee charged to the ISP that provides another communication network is calculated higher. Further, when unnecessary data is transmitted to another communication network, the communication network 10-1 is considered to be damaging to the other communication network. Therefore, as the amount of unnecessary data transmitted from the communication network 10-1 to the other communication network increases as the price of damage caused by the communication network 10-1 to the other communication network, the calculation device 100-1 increases the ISP 10p. -1 calculates the additional fee paid to other ISPs high.

  In the example shown in FIG. 1, the communication network 10-1 and the communication network 10-2 are connected by transit. Accordingly, the calculation device 100-1 calculates the additional charge that the ISP 10p-1 charges to the ISP 10p-2 as the amount of unnecessary data received by the communication network 10-1 from the communication network 10-2 increases. In addition, the calculation device 100-1 calculates a higher additional fee that the ISP 10p-1 pays to the ISP 10p-2 as the amount of unnecessary data transmitted from the communication network 10-1 to the communication network 10-2 increases.

  Here, the reason why the calculation processing by the calculation device 100-1 in the first embodiment differs depending on the connection form between the communication networks will be described. In the first embodiment, when the connection form is peering, it is assumed that no connection fee is charged between both ISPs connected to the communication network. For this reason, when the connection form is peering, one of the two ISPs to which the communication network is connected by peering may charge an additional charge according to unnecessary data. In the first embodiment, when the connection form is peering, both ISPs calculate an additional fee based on the received unnecessary data, and charge the calculated additional fee to the other ISP.

  In the example shown in FIG. 1, the communication network 10-1 and the communication network 10-4 are connected by peering. Accordingly, the calculation device 100-1 of the ISP 10p-1 calculates an additional fee that the ISP 10p-1 charges to the ISP 10p-4 based on the amount of unnecessary data received from the communication network 10-4 by the communication network 10-1. . Similarly, the calculation device 100-4 of the ISP 10p-4 increases the additional charge that the ISP 10p-4 charges to the ISP 10p-1 based on the amount of unnecessary data received by the communication network 10-4 from the communication network 10-1. Calculate.

  On the other hand, in the first embodiment, when the connection form is transit, it is assumed that one ISP periodically charges the connection fee to the other ISP. In the example shown in FIG. 1, the ISP 10p-1 of the communication network 10-1 periodically charges the connection fee to the ISP 10p-2 of the communication network 10-2. At this time, if the ISP 10p-2 charges the ISP 10p-1 with an additional fee according to unnecessary data, the charging form and the like become complicated. Further, even if ISP 10p-1 charges ISP 10p-2 with an additional charge according to unnecessary data at a timing different from the connection charge, the charging form and the like become complicated.

  Therefore, in the first embodiment, when one ISP charges the connection fee to the other ISP, the one ISP calculates the additional fee based on the amount of unnecessary data distributed between the two ISPs. The connection fee obtained by adding or subtracting the calculated additional fee is charged to the other ISP. In the example shown in FIG. 1, the calculation device 100-1 of the ISP 10p-1 increases the connection fee charged to the ISP 10p-2 as the amount of unnecessary data received from the communication network 10-2 by the communication network 10-1 increases. The connection fee charged to the ISP 10p-2 is reduced as the amount of unnecessary data transmitted to the communication network 10-2 by the communication network 10-1 increases.

  As described above, in the first embodiment, when the connection form is peering, both ISPs charge an additional fee. Therefore, the calculation device 100-1 of the ISP 10p-1 uses unnecessary data received from the communication network 10-4 by the communication network 10-1 when calculating the additional fee charged to the ISP 10p-4. In the first embodiment, when the connection form is transit, an additional fee calculated according to the amount of unnecessary data is charged together with the connection fee. Accordingly, the calculation device 100-1 of the ISP 10p-1 that charges the connection fee to the ISP 10p-2 does not need to receive the communication network 10-1 from the communication network 10-2 when calculating the additional fee according to the unnecessary data. Both the data and unnecessary data transmitted from the communication network 10-1 to the communication network 10-2 are used.

  Next, with reference to the example shown in FIG. 2, the additional fee calculation process performed by the calculation device 100-1 described above will be described. FIG. 2 is a diagram for explaining an example of an additional charge calculation process performed by the calculation apparatus 100-1 according to the first embodiment. In FIG. 2, the calculation process by the calculation device 100-1 will be described by taking the communication network 10-1 and the communication network 10-2 connected by transit as an example.

  In the state on the left side of FIG. 2, it is assumed that the communication network 10-1 transmits legitimate data that is not unnecessary data to the communication network 10-2 in a predetermined period. FIG. 2 shows that the amount of legitimate data transmitted from the communication network 10-1 to the communication network 10-2 during the predetermined period is “T1”. In addition, it is assumed that the communication network 10-2 transmits legitimate data having a data amount “T2” to the communication network 10-1 during a predetermined period. Here, it is assumed that unnecessary data is not transmitted and received between the communication network 10-1 and the communication network 10-2 in a predetermined period.

  In this case, the charging device 12-1 in the communication network 10-1 calculates the connection fee “F1” for charging the ISP 10p-2 based on the data “T1” and “T2”. For example, the calculation device 100-1 calculates the connection fee “F1” by the following equation (1).

F1 = α1 (T1 + T2) ^α2 (1)

  In the above formula (1), “α1” indicates a transit coefficient, and “α2” indicates a transit order. The transit coefficient “α1” and the transit order “α2” are determined in advance between the ISP 10p-1 and the ISP 10p-2. When the above equation (1) is used, the charging device 12-1 calculates a higher connection fee as the sum of the data “T1” and the data “T2” is larger. In this way, the billing apparatus 12-1 calculates the billing amount “F1” that is periodically billed to the ISP 10p-2.

  Subsequently, in the state on the right side of FIG. 2, as in the above example, the communication network 10-1 transmits legitimate data having a data amount “T1” to the communication network 10-2 in a predetermined period. The communication network 10-2 transmits legitimate data having a data amount “T2” to the communication network 10-1. Then, the calculation device 100-1 in the communication network 10-1 calculates the connection fee “F1” charged by the ISP 10p-1 to the ISP 10p-2, as in the above example.

  Further, in the state on the right side of FIG. 2, the communication network 10-1 transmits unnecessary data having a data amount “U1” to the communication network 10-2. That is, the communication network 10-1 is considered to be damaging to the communication network 10-2 by transmitting unnecessary data to the communication network 10-2. Therefore, the calculation device 100-1 pays an additional fee based on the amount of unnecessary data “U1” in order to reduce the connection fee “F1” charged by the ISP 10p-1 to the ISP 10p-2 as a compensation for such damage. Calculate.

  In the state on the right side of FIG. 2, the communication network 10-2 transmits unnecessary data having a data amount “U2” to the communication network 10-1. That is, it is considered that the communication network 10-1 has received unnecessary data of the data amount “U2” from the communication network 10-2 and suffered damage from the communication network 10-2. Therefore, the calculation device 100-1 pays an additional fee based on the amount of unnecessary data “U2” in order to increase the connection fee “F1” charged by the ISP 10p-1 to the ISP 10p-2 as a compensation for such damage. Calculate.

  For example, the calculation device 100-1 calculates an additional fee “F2” for increasing or decreasing the connection fee “F1” by the following equation (2).

F2 = β1 (−U1 + U2) ^β2 (2)

  In the above formula (2), “β1” indicates an unnecessary data transit coefficient, and “β2” indicates an unnecessary data transit order. The unnecessary data transit coefficient “β1” and the unnecessary data transit order “β2” are determined in advance between the ISP 10p-1 and the ISP 10p-2.

  As shown in the above equation (2), the data amount “U1” of unnecessary data transmitted from the communication network 10-1 to the communication network 10-2 is the unnecessary amount received from the communication network 10-2 by the communication network 10-1. When the amount of data is greater than “U2”, the additional charge “F2” calculated by the calculation device 100-1 is a negative value. On the other hand, the data amount “U1” of unnecessary data transmitted from the communication network 10-1 to the communication network 10-2 is greater than the data amount “U2” of unnecessary data received by the communication network 10-1 from the communication network 10-2. If the amount is too small, the additional charge “F2” calculated by the calculation device 100-1 is a positive value.

  Then, the charging device 12-1 adds the additional fee “F2” calculated by the calculating device 100-1 to the connection fee “F1” calculated based on the data amount “T1 + T2” of the legitimate data, thereby obtaining the ISP 10p. -2 is calculated as “F1 + F2” which is charged periodically.

  As described above, when the data amount “U1” is larger than the data amount “U2”, the additional fee “F2” becomes a negative value, and the charging device 12-1 charges the ISP 10p-2. The connection fee “F1” will be reduced. Further, when the data amount “U1” is smaller than the data amount “U2”, the additional fee “F2” is a positive value. Therefore, the charging device 12-1 charges the connection fee “F1” to the ISP 10p-2. Will be increased.

  In the above description, the various apparatuses included in the communication network 10-1 have been mainly described. However, the various apparatuses included in the communication networks 10-2, 10-4, and 10-5 are also included in the communication network 10-1. The same processing is performed. For example, the charging device 12-2 in the communication network 10-2 calculates the connection fee based on the amount of legitimate data transmitted and received between the communication network 10-2 and the communication network 10-3. The calculation device 100-2 in the communication network 10-2 includes unnecessary data received from the communication network 10-3 by the communication network 10-2 and unnecessary data transmitted from the communication network 10-2 to the communication network 10-3. Based on the above, the surcharge is calculated.

  Further, FIG. 1 shows an example in which the communication networks 10-3 and 10-6 do not charge other ISPs, and thus the communication networks 10-3 and 10-6 do not include the charging device and the calculation device. ing. However, the billing device and the calculation device may also be included in the communication networks 10-3 and 10-6.

  As described above, in the network system 1 according to the first embodiment, between the communication networks connected by transit, the calculation device in one ISP charges the other ISP according to the amount of legitimate data. Calculate the connection fee and increase or decrease the connection fee according to the amount of unnecessary data. Further, in the network system 1 according to the first embodiment, between the communication networks connected by peering, both ISP calculation devices charge the other ISP according to the amount of unnecessary data received from the other ISP. Calculate the surcharge to be paid.

  As a result, in the network system 1 according to the first embodiment, an additional fee is charged for the ISP that transmits unnecessary data. Therefore, it is possible to prevent each ISP from transmitting unnecessary data. In other words, in the network system 1, outbound control such as a service for suppressing transmission of unnecessary data can be introduced to each ISP. As a result, the network system 1 according to the first embodiment can reduce the amount of unnecessary data distributed.

[Configuration of Calculation Device in Example 1]
Next, the calculation devices 100-1, 100-2, 100-4, and 100-5 shown in FIG. 1 will be described in detail. In the following, processing by the calculation device 100-1 and the like will be described by taking as an example a case where unnecessary data is a junk mail. In the following, when it is not necessary to distinguish between the calculation devices 100-1, 100-2, 100-4, and 100-5, they may be collectively referred to as “calculation device 100”. Similarly, when it is not necessary to distinguish the communication networks 10-1 to 10-6, they may be collectively referred to as “communication network 10”, and the service providing apparatuses 11-1 to 11-6 may be referred to as “communication networks 10-1 to 11-6”. When there is no need to distinguish between them, these may be collectively referred to as “service providing apparatus 11”, and there is no need to distinguish between the charging apparatuses 12-1, 12-2, 12-4, and 12-5. In some cases, these may be collectively referred to as “charging device 12”.

  First, the configuration of the calculation apparatus shown in FIG. 1 will be described with reference to FIG. FIG. 3 is a diagram illustrating a configuration example of the calculation device 100 according to the first embodiment. As illustrated in FIG. 3, the calculation device 100 according to the first embodiment includes an IF (Interface) unit 110, a storage unit 120, and a control unit 130.

  The IF unit 110 transmits / receives various data to / from other devices. For example, if the communication network to which the calculation apparatus 100 belongs receives an electronic mail from another communication network, the IF unit 110 accepts the received mail. Further, for example, the IF unit 110 receives the transmission mail when the communication network to which the calculation apparatus 100 belongs transmits an electronic mail to another communication network. For example, the IF unit 110 transmits additional fee information to the charging device 12 in the communication network to which the calculation device 100 belongs. In the following, the communication network to which the calculation device 100 belongs may be referred to as “own communication network”.

  The storage unit 120 is a storage device that stores various types of information, and is, for example, a semiconductor memory element such as a RAM (Random Access Memory) or a flash memory, or a storage device such as a hard disk or an optical disk. As illustrated in FIG. 3, the storage unit 120 includes a determination condition storage unit 121, a junk mail number storage unit 122, a calculation condition storage unit 123, and an additional charge storage unit 124.

  The determination condition storage unit 121 stores a condition that the e-mail is a junk mail. The determination condition storage unit 121 is referred to when the determination unit 131, which will be described later, determines whether an e-mail is a junk mail.

  FIG. 4 illustrates an example of the determination condition storage unit 121 according to the first embodiment. In the example illustrated in FIG. 4, the determination condition storage unit 121 includes items such as “determination target item” and “determination condition”. The “determination target item” indicates an item used when it is determined whether or not it is a spam mail among various items included in the e-mail. FIG. 4 shows an example in which items such as an e-mail subject (Subject) and a transmission source (From) are stored in the “determination target item”. The “determination condition” indicates a condition that the electronic mail is a spam mail.

  For example, in FIG. 4, when the subject (Subject) of the e-mail is “aaa”, this indicates that the e-mail is a junk mail. In FIG. 4, when “bbb” is included in the subject of the electronic mail (Subject), it indicates that the electronic mail is a junk mail. In FIG. 4, when the domain part of the e-mail transmission source (From) is “xxx.xx” or when “yyy” is included in the e-mail transmission source (From), such e-mail is sent. Indicates spam.

  Various types of information stored in the determination condition storage unit 121 are determined in advance between ISPs. For example, in the example illustrated in FIG. 4, the determination condition storage unit 121 stores a determination condition that is determined in advance between the ISP 10 p-1 and the ISP 10 p-2 or between the ISP 10 p-1 and the ISP 10 p-4. Note that the determination condition storage unit 121 may store different determination conditions for each of the other communication networks connected to the own communication network. For example, when the determination condition determined between ISP10p-1 and ISP10p-2 is different from the determination condition determined between ISP10p-1 and ISP10p-4, the determination condition storage unit 121 Determination conditions used when determining an electronic mail transmitted / received between the communication network 10-1 and the communication network 10-2, and an electron transmitted / received between the communication network 10-1 and the communication network 10-4. You may hold | maintain separately the determination conditions used when determining mail.

  In the example illustrated in FIG. 4, the determination condition storage unit 121 illustrates an example in which the condition that the electronic mail is junk mail is stored. In other words, FIG. 4 shows an example in which the determination condition storage unit 121 stores the determination conditions in the blacklist format. However, the determination conditions stored in the determination condition storage unit 121 are not limited to this example. For example, the determination condition storage unit 121 may store a condition that the e-mail is not a junk mail as a white list format. For example, the determination condition storage unit 121 stores a determination condition indicating that the e-mail is not junk mail when “ccc” is included in the subject (Subject) of the e-mail. Alternatively, if the domain part of the e-mail transmission source (From) is “zzz.zzz”, a determination condition indicating that the e-mail is not junk mail may be stored.

  Returning to the description of FIG. 3, the spam mail number storage unit 122 stores the number of spam mails transmitted and received between the local communication network and another communication network. The junk mail number storage unit 122 is updated by a calculation unit 132 described later and is referred to by a calculation unit 133 described later.

  FIG. 5 illustrates an example of the junk mail number storage unit 122 according to the first embodiment. Note that the spam mail number storage unit 122 illustrated in FIG. 5 is included in the calculation device 100-1 illustrated in FIG. In the example illustrated in FIG. 5, the spam mail number storage unit 122 includes items such as “communication network”, “spam mail reception count”, and “spam mail transmission count”.

  “Communication network” indicates information for identifying another communication network connected to the communication network 10-1 to which the calculation device 100-1 belongs. In the example shown in FIG. 5, the “communication network” of the junk mail number storage unit 122 stores the reference numerals attached to the communication network shown in FIG. 1 as information for identifying the communication network. To do. For example, the communication network “10-2” stored in the spam mail number storage unit 122 indicates the communication network 10-2, and the communication network “10-4” stored in the spam mail number storage unit 122 indicates communication. The network 10-4 is shown. The “number of spam mails received” indicates the number of spam mails received by the communication network 10-1 from other communication networks. The “number of spam mail transmissions” indicates the number of spam mails transmitted from the communication network 10-1 to another communication network.

  For example, in FIG. 5, the number of spam mails received by the communication network 10-1 from the communication network 10-2 is “100,000”, and the number of spam mails sent by the communication network 10-1 to the communication network 10-2 is “5000”. Further, for example, FIG. 5 shows that the number of junk mails received by the communication network 10-1 from the communication network 10-4 is “2000”. Since the communication network 10-1 and the communication network 10-4 are connected by peering, the junk mail number storage unit 122 according to the first embodiment is annoying that the communication network 10-1 transmits to the communication network 10-4. Does not remember the number of emails sent.

  In the example illustrated in FIG. 5, the junk mail number storage unit 122 stores the junk mail reception number and the junk mail transmission number separately, but the junk mail number storage unit 122 stores the junk mail reception number and the junk mail reception number. The number of spam mail transmission / reception may be integrated to store the number of spam mail transmission / reception. For example, the spam mail number storage unit 122 uses the number of spam mails received by the communication network 10-1 from another communication network as the number of spam mail transmission / reception, and the spam mail transmitted from the communication network 10-1 to the other communication network. The number obtained by subtracting the number may be stored. Referring to the example shown in FIG. 5, the spam mail number storage unit 122 stores the spam mail transmission / reception number “+95000” in association with the communication network “10-2”, and the communication network “10-4”. The number of spam mail transmission / reception “+2000” may be stored in association with Further, for example, the number of spam mails received by the communication network 10-1 from the communication network 10-2 is “1000”, and the number of spam mails transmitted by the communication network 10-1 to the communication network 10-2 is “5000”. ", The spam mail number storage unit 122 may store the spam mail transmission / reception number" -4000 "in association with the communication network" 10-2 ".

  Returning to the description of FIG. 3, the calculation condition storage unit 123 stores the calculation condition of the additional fee. The calculation condition storage unit 123 is referred to when the additional fee is calculated by the calculation unit 133 described later.

  FIG. 6 shows an example of the calculation condition storage unit 123 in the first embodiment. Note that the calculation condition storage unit 123 illustrated in FIG. 6 is included in the calculation device 100-1 illustrated in FIG. In the example illustrated in FIG. 6, the calculation condition storage unit 123 includes items such as “communication network” and “calculation condition”. The “communication network” corresponds to the “communication network” shown in FIG. “Calculation condition” indicates a calculation condition of an additional fee calculated according to the number of spam mails. In the example shown in FIG. 5, “calculation condition” stores an expression for calculating the additional fee.

For example, FIG. 6 shows that the additional fee charged by ISP 10p-1 to ISP 10p-2 is calculated by “β11 × N ^β12 ”. Further, for example, FIG. 6 shows that the additional fee charged by the ISP 10p-1 to the ISP 10p-4 is calculated by “β21 × ^Nβ22 ”.

  Of the formulas stored in the “calculation condition” shown in FIG. 6, “N” is a value obtained by subtracting the number of junk mail transmissions from the number of junk mails received in the junk mail number storage unit 122 illustrated in FIG. “Β11” and “β21” indicate unnecessary data transit coefficients, and “β12” and “β22” indicate unnecessary data transit orders. The unnecessary data transit coefficient “β11” and the unnecessary data transit order “β12” are determined in advance between the ISP 10p-1 and the ISP 10p-2, and the unnecessary data transit coefficient “β21” and the unnecessary data transit order “β22” are set to the ISP 10p. -1 and ISP10p-4.

  Here, it is desirable that the unnecessary data transit orders “β12” and “β22” are larger than “1”. This will be specifically described with reference to FIG. FIG. 7 is a diagram showing the fluctuation amount of the additional charge according to the unnecessary data transit order. As shown in FIG. 7, when the unnecessary data transit orders “β12” and “β22” are less than “1”, the amount of increase in the additional charge decreases as the number of spam mails “N” increases. On the other hand, when the unnecessary data transit orders “β12” and “β22” are “1”, the additional charge increases in proportion to the number of spam mails “N”. When the unnecessary data transit orders “β12” and “β22” are larger than “1”, the additional charge increases exponentially as the number of spam mails “N” increases.

  That is, when the unnecessary data transit orders “β12” and “β22” are larger than “1”, the amount of increase in additional charges increases as the number of spam mails “N” increases. The effect of suppressing spam mail transmission to the ISP increases. In addition, when the ISP 10p-1 itself sends a large amount of junk mail to the connection destination communication network, the ISP 10p-1 itself pays a high additional charge to the ISP of the connection destination communication network. For this reason, when the unnecessary data transit orders “β12” and “β22” are larger than “1”, the spam mail transmission suppression effect is enhanced, so the number of spam mails circulating in the network system 1 is further reduced. It becomes possible to make it.

  Returning to the description of FIG. 3, the additional charge storage unit 124 stores additional charge information indicating the additional charge calculated according to the number of spam mails. The additional charge storage unit 124 is updated by a calculation unit 133 described later and is referred to by a notification unit 134 described later.

  FIG. 8 illustrates an example of the additional charge storage unit 124 according to the first embodiment. The additional charge storage unit 124 illustrated in FIG. 8 is assumed to be included in the calculation device 100-1 illustrated in FIG. In the example illustrated in FIG. 8, the additional charge storage unit 124 includes items such as “communication network” and “additional charge information”. The “communication network” corresponds to the “communication network” shown in FIG. “Additional charge information” indicates an additional charge calculated according to the number of spam mails. When the value stored in the “additional charge information” is “+ (plus)”, this indicates that the ISP 10p-1 charges an additional charge to another ISP, and is stored in the “additional charge information”. When the value is “− (minus)”, it indicates that the ISP 10p-1 pays an additional fee to another ISP.

  For example, FIG. 8 shows that the additional fee charged by ISP 10p-1 to ISP 10p-2 is “+ F11”. That is, in this example, the ISP 10p-1 increases the connection fee charged to the ISP 10p-2 by “F11”. Further, for example, FIG. 8 shows that the additional fee charged by the ISP 10p-1 to the ISP 10p-4 is “F12”. Although not shown in FIG. 8, for example, the additional charge storage unit 124 stores the communication network “10-2” and the additional charge information “−F13” in association with each other. 1 indicates that the connection fee charged to the ISP 10p-2 is reduced by “F13”.

  Returning to the description of FIG. 3, the control unit 130 is a control device that controls the calculation apparatus 100 as a whole. For example, a central processing unit (CPU), a micro processing unit (MPU), and an application specific integrated circuit (ASIC). Etc. The control unit 130 includes a determination unit 131, a calculation unit 132, a calculation unit 133, and a notification unit 134.

  The determination unit 131 determines whether an electronic mail transmitted / received between the local communication network and another communication network is a junk mail. Specifically, the determination unit 131 receives an e-mail from the IF unit 110 when the self-communication network receives an e-mail from another communication network. Then, the determination unit 131 determines whether the received mail received from the IF unit 110 is a junk mail based on the determination conditions stored in the determination condition storage unit 121.

  Further, the determination unit 131 receives the e-mail from the IF unit 110 when the own communication network transmits the e-mail to another communication network. Then, the determination unit 131 ends the process when the local communication network and the e-mail transmission destination communication network are connected by peering. On the other hand, when the communication network and the destination communication network of the e-mail are connected by transit, the determination unit 131 determines whether the IF unit 110 performs the determination based on the determination condition stored in the determination condition storage unit 121. It is determined whether the received outgoing mail is a junk mail.

  For example, assume that various types of information stored in the determination condition storage unit 121 are in the state illustrated in FIG. Then, it is assumed that the communication network 10-1 has received an electronic mail having the subject “aaa” from the communication network 10-2. In such a case, the determination unit 131 of the calculation apparatus 100-1 determines that the subject “aaa” of the email received by the communication network 10-1 corresponds to the determination target item “subject” in the determination condition storage unit 121. Since “matches“ aaa ”” is satisfied, it is determined that the communication network 10-1 has received junk mail from the communication network 10-2.

  In the above example, it is assumed that the communication network 10-1 receives an e-mail with the subject “ccc” from the communication network 10-2. In such a case, the determination unit 131 of the calculation apparatus 100-1 determines that the subject name “ccc” of the email received by the communication network 10-1 corresponds to the determination target item “subject” in the determination condition storage unit 121. Since neither is satisfied, it is determined that the communication network 10-1 has received an e-mail that is not a junk mail from the communication network 10-2.

  When the determination condition storage unit 121 stores the determination condition in the white list format, the determination unit 131 determines that the e-mail transmitted and received by the communication network 10-1 is stored in the determination condition storage unit 121. If none of the conditions are met, it is determined that the electronic mail is a spam mail. In other words, the determination unit 131 determines that the e-mail is not a junk mail when the e-mail transmitted and received by the communication network 10-1 satisfies even one determination condition stored in the determination condition storage unit 121. judge.

  The calculation unit 132 calculates the number of junk mails determined by the determination unit 131 and stores the calculated number of junk mails in the junk mail number storage unit 122. Specifically, when the determination unit 131 determines that the received mail is junk mail, the calculation unit 132 stores the junk mail number storage unit for each communication network that has transmitted an e-mail to the local communication network. The number of 122 junk mails received is counted up. In addition, when the determination unit 131 determines that the transmitted mail is junk mail, the calculation unit 132 sets the junk mail transmission number in the junk mail number storage unit 122 for each communication network that is the destination of the e-mail. Count up.

  For example, when the determination unit 131 determines that the communication network 10-1 has received junk mail from the communication network 10-2, the calculation unit 132 sets the communication network “10-2” in the junk mail number storage unit 122. Count the number of junk mail received corresponding to.

  Note that the calculation unit 132 updates the junk mail reception number and junk mail transmission number stored in the junk mail number storage unit 122 to “0” every predetermined period. For example, the calculation unit 132 clears the junk mail reception number and the junk mail transmission number stored in the junk mail number storage unit 122 to “0” after the billing performed between the ISPs is completed.

  The calculation unit 133 refers to the junk mail number storage unit 122 and the calculation condition storage unit 123 for each predetermined period (for example, one month) and calculates an additional charge according to the number of junk mails. Specifically, the calculation unit 133 calculates the number “N” of junk mails obtained by subtracting the number of junk mail transmissions from the number of junk mails received for each communication network stored in the junk mail number storage unit 122. Then, the calculation unit 133 calculates an additional charge according to the number of junk mails using the number “N” of junk mails calculated for each communication network and the calculation conditions corresponding to the communication network in the calculation condition storage unit 123. . Then, the calculating unit 133 stores the calculated additional fee in the additional fee storage unit 124.

For example, it is assumed that the various information stored in the junk mail number storage unit 122 is in the state shown in FIG. 5, and the various information stored in the calculation condition storage unit 123 is in the state shown in FIG. In this case, the calculation unit 133 subtracts the spam mail transmission number “5000” from the spam mail reception number “100000” corresponding to the communication network “10-2” of the spam mail number storage unit 122, thereby obtaining the number of spam mails. “N” = “95000” is calculated. Then, the calculation unit 133 acquires the calculation condition “β11 × N ^β12 ” corresponding to the communication network “10-2” in the calculation condition storage unit 123, and ^sets “N” in the acquired calculation condition “β11 × N ^β12 ”. The additional charge is calculated by substituting “95000”. Then, the calculation unit 133 stores the calculated additional charge in the additional charge information corresponding to the communication network “10-2” in the additional charge storage unit 124. The calculation unit 133 performs the same process for the communication network “10-4”.

  The notification unit 134 notifies the charging device 12 in the local communication network of the additional fee calculated by the calculation unit 133 every predetermined period (for example, one month). Specifically, the notification unit 134 acquires the combination of the communication network and the additional charge information stored in the additional charge storage unit 124 and notifies the charging apparatus 12 of the acquired combination of the communication network and the additional charge information. To do.

  For example, it is assumed that various information stored in the additional charge storage unit 124 is in the state illustrated in FIG. In such a case, the notification unit 134 acquires “10-2, + F11” and “10-4, +12” as a combination of “communication network and additional fee information” from the additional fee storage unit 124, and acquires the acquired information. Notify billing device 12. As a result, the charging device 12 charges the ISP 10p-2 with a charging amount obtained by adding the additional fee “F11” to the connection fee. The charging device 12 charges the ISP 10p-2 of the communication network 10-4 using the additional fee “F12” as the charging amount.

[Procedure for calculating the number of junk mails by the calculation device in Embodiment 1]
Next, a procedure for calculating the number of junk mails performed by the calculation apparatus 100 according to the first embodiment will be described with reference to FIG. FIG. 9 is a flowchart illustrating a procedure for calculating the number of junk mails by the calculation device 100 according to the first embodiment.

  As illustrated in FIG. 9, the determination unit 131 of the calculation apparatus 100 determines the determination condition stored in the determination condition storage unit 121 when the communication network receives an e-mail from another communication network (Yes in step S101). Based on the above, it is determined whether or not the received mail is a spam mail (step S102).

  When the determination unit 131 determines that the received mail is a junk mail (Yes in step S102), the calculation unit 132 of the calculation device 100 stores the number of junk mails corresponding to the communication network that transmitted the e-mail. The number of junk mails received by the unit 122 is counted up (step S103). On the other hand, when the determination unit 131 determines that the received mail is not spam (No in step S102), the calculation unit 132 returns to the process of step S101.

  In addition, the determination unit 131 of the calculation device 100 may send an e-mail to another communication network even if the own communication network has not received an e-mail from another communication network (No in step S101). If it has been transmitted (Yes at Step S104), it is determined whether or not the own communication network is connected to the destination communication network for electronic mail by transit (Step S105). When the communication network is not connected to the electronic mail transmission destination communication network by transit (No at Step S105), the determination unit 131 returns to Step S101.

  On the other hand, when the own communication network is connected to the e-mail transmission destination communication network by transit (Yes at Step S105), the determination unit 131, based on the determination condition stored in the determination condition storage unit 121, It is determined whether or not the transmitted mail is a spam mail (step S106).

  Then, when the determination unit 131 determines that the outgoing mail is spam (Yes in step S106), the calculation unit 132 of the calculation device 100 determines the number of spams corresponding to the communication network to which the electronic mail is transmitted. The number of spam mail transmissions in the storage unit 122 is counted up (step S107). On the other hand, when the determination unit 131 determines that the transmitted mail is not spam (No in step S106), the calculation unit 132 returns to the process of step S101.

[Calculation procedure of additional charge by calculation device in Example 1]
Next, the additional charge calculation processing procedure by the calculation device 100 according to the first embodiment will be described with reference to FIG. FIG. 10 is a flowchart illustrating the additional fee calculation processing procedure performed by the calculation device 100 according to the first embodiment.

  As illustrated in FIG. 10, the calculation unit 133 of the calculation device 100 determines whether or not it is the calculation timing of the additional charge (step S201). Note that the calculation timing indicates the timing at which billing processing is performed between ISPs, and occurs every other month, for example.

  Then, when it is the calculation timing (Yes at Step S201), the calculation unit 133 subtracts the junk mail transmission number from the junk mail reception number for each communication network stored in the junk mail number storage unit 122. “N” is calculated (step S202).

  Subsequently, the calculation unit 133 calculates an additional charge according to the number of junk mails using the number of junk mails “N” and the calculation conditions corresponding to the communication network of the calculation condition storage unit 123 (step S203).

  Subsequently, the calculation unit 133 stores the additional fee calculated in step S203 in the additional fee storage unit 124 (step S204). Then, the notification unit 134 notifies the charging device 12 in the local communication network of the additional fee stored in the additional fee storage unit 124 (step S205). Thereby, the charging device 12 charges the connection fee increased or decreased by the additional fee notified from the notification unit 134 to the other ISP, or charges the additional ISP notified from the notification unit 134 to the other ISP. .

[Effect of Example 1]
As described above, in the network system 1 according to the first embodiment, the calculation device 100 is determined to be unnecessary in advance between ISPs among data received by the communication network from other communication networks. Calculate the amount of data. Then, the calculation device 100 calculates a higher charge amount to be imposed on the ISP that provides another communication network as the amount of such unnecessary data increases.

  As a result, in the network system 1 according to the first embodiment, each ISP can suppress transmission of unnecessary data. Therefore, outbound control such as a service for suppressing transmission of unnecessary data is introduced into each ISP. Can be promoted. As a result, the network system 1 according to the first embodiment can reduce the amount of unnecessary data distributed. For example, when communication networks are connected by peering or the like and connection fees are not charged between ISPs, additional fees according to unnecessary data can be charged between ISPs.

  In addition, the network system 1 according to the first embodiment uses the amount of unnecessary data that is determined to be unnecessary between ISPs in advance among the data that the calculation device 100 transmits to another communication network. The higher the amount of unnecessary data calculated, the higher the amount charged by other ISPs.

  As a result, in the network system 1 according to the first embodiment, each ISP can suppress transmission of unnecessary data, so that the amount of unnecessary data distributed can be reduced. For example, when the communication networks are connected by transit or the like, and the connection fee is charged between ISPs, the ISP that charges the connection fee charges the additional fee according to unnecessary data on the other side. An ISP can be charged, or an additional fee according to unnecessary data can be paid to the other ISP.

  In addition, in the network system 1 according to the first embodiment, when the calculation device 100 charges the connection fee from one ISP to the other ISP, the amount of data received by the local communication network from the other communication network is The connection charge is increased as the number increases, and the connection charge is decreased as the amount of data transmitted from the local communication network to the other communication network increases.

  As a result, in the network system 1 according to the first embodiment, the ISP can charge the other ISP with an additional fee according to unnecessary data together with the connection fee. That is, the network system 1 according to the first embodiment can charge an additional fee without complicating the charging form.

  Further, the charging system for additional charges in the first embodiment described above (hereinafter sometimes referred to as “additional charging system”) has an effect of being easily introduced into each ISP. This point will be specifically described with reference to FIGS. 11 and 12. 11 and 12 are diagrams illustrating an introduction example of the additional charge system in the first embodiment.

  In FIG. 11, the example of the communication network provided by ISP21p-26p is shown. Here, in the example shown in FIG. 11, it is assumed that the ISPs 21p and 22p have introduced the additional charging system and the ISP 23p has not introduced the additional charging system. In such a case, a malicious ISP that transmits a large amount of unnecessary data transmits unnecessary data to the ISP 23p for which no additional fee is charged. In other words, many malicious ISPs are connected to the ISP 23p that has not introduced the additional charge system. As a result, the ISP 23p does not charge the ISPs 24p to 26p for an additional fee, while the ISP 23p communication network transmits a large amount of unnecessary data to the ISP 22p communication network, thereby paying the ISP 22p a high additional fee. For this reason, the ISP 23p suffers a damage of paying a high additional fee. The ISP 22p may be charged a high additional fee from the ISP 21p by transmitting a large amount of unnecessary data received from the ISP 23p to the communication network of the ISP 21p. However, the ISP 22p can apply the additional fee charged to the ISP 23p to the additional fee paid to the ISP 21p, so that at least no damage is incurred.

  For this reason, ISP 23p is more conscious of introducing an additional charge system. And as shown in FIG. 12, when ISP23p introduces an additional charge system, ISP24p-26p pays an additional charge to ISP23p. That is, the consciousness of introducing the additional charge system to the ISPs 24p to 26p is increased, or the consciousness of introducing the outbound control such as countermeasures against spam mails is increased.

  As described above, the additional charging system in the first embodiment has an effect that it is easily introduced into each ISP for the purpose of avoiding damage due to the charging of the additional fee. That is, the additional charge system in the first embodiment is highly likely to spread to each ISP, and can further raise the awareness of introducing outbound control.

  Further, as can be seen from the examples shown in FIG. 11 and FIG. 12, the additional charge system described in the first embodiment does not need to be introduced to all ISPs in the network system. Even if it is introduced, it is possible to reduce unnecessary data while satisfying the requirements of the ISP that has introduced the additional charging system and the ISP that has introduced the additional charging system.

  By the way, the calculation apparatus, network system, calculation method, and calculation program according to the present invention may be implemented in various different forms other than the above-described embodiments. Therefore, in the second embodiment, another embodiment of the calculation device, the network system, the calculation method, and the calculation program according to the present invention will be described.

[Number of spam mails]
Although FIG. 3 shows an example in which the calculation device 100 calculates the additional fee based on the number of spam mails, the calculation device 100 may calculate the additional fee based on the size of the spam mail. . As an example, the calculation device 100 in the communication network 10-1 determines that the ISP providing the other communication network is larger as the total size of junk mail received by the communication network 10-1 from the other communication network is larger. The additional fee to be charged is calculated to be higher, and the additional fee paid to the ISP providing the other communication network is higher as the total size of the junk mail transmitted from the communication network 10-1 to the other communication network is larger.

Spam mail weighting
3 shows an example in which the calculation device 100 calculates the additional fee based on the number of spam mails. However, the calculation device 100 weights spam mails according to the types of spam mails. The additional charge may be calculated based on the weight of the junk mail.

[Billing amount calculation process]
In the first embodiment, the charging device 12 calculates the connection fee and the calculation device 100 calculates the additional fee. However, the calculation device 100 may calculate the additional fee and the connection fee. In such a case, the calculation device 100 calculates a connection fee based on legitimate data and calculates an additional fee based on unnecessary data. Then, the calculation device 100 adds or subtracts the additional fee to the connection fee, and notifies the charging device 12 of the charged amount after the addition or subtraction. Then, the billing device 12 charges the billing amount notified from the calculation device 100 to another ISP.

[Timing for additional charges]
In the first embodiment, when the connection form is transit, one ISP charges an additional fee together with the connection fee to the other ISP. However, one ISP has a connection fee and an additional fee. May be charged to the other ISP at different timings.

[Calculator for additional charges]
In the first embodiment, when the connection form is peering, both ISPs calculate an additional fee based on unnecessary data received from the other ISP, and charge the calculated additional fee to the other ISP. An example to do. However, both ISPs may calculate an additional fee based on unnecessary data transmitted to the other ISP, and pay the calculated additional fee to the other ISP. Or, even when the connection form is peering, as in the case where the connection form is transit, both ISPs receive unnecessary data received from the other ISP and unnecessary data transmitted to the other ISP. The additional fee may be calculated based on the data, and the additional fee may be charged to the other ISP, or the additional fee may be paid to the other ISP.

[Calculator for additional charges]
Further, in the first embodiment, when the connection form is transit, the ISP that charges the connection fee is charged based on the unnecessary data received from the other ISP and the unnecessary data transmitted to the other ISP. An example is shown in which the calculated additional charge is charged to the other ISP together with the connection charge. However, even if the connection form is transit, both ISPs calculate additional charges based on unnecessary data received from the other ISP, as in the case where the connection form is peering. The fee may be charged to the other ISP. Alternatively, even if the connection form is transit, both ISPs may calculate an additional fee based on unnecessary data transmitted to the other ISP, and pay the calculated additional fee to the other ISP.

[Calculator for additional charges]
In the first embodiment, either one of the ISPs connected to the communication network calculates the additional fee based on the unnecessary data received from the other ISP, or the unnecessary data received from the other ISP and the other ISP. An example of calculating the additional fee based on the unnecessary data transmitted to the ISP has been shown. However, both ISPs connected to the communication network may calculate additional charges based on unnecessary data received from the other ISP and unnecessary data transmitted to the other ISP. In such a case, when the additional fee calculated by both ISPs matches, the additional fee can be charged, so that the additional fee can be prevented from being camouflaged.

  As described above, in the additional charge system described in the first embodiment, when attention is paid to ISPs connected to each other, the form in which one ISP-A and the other ISP-B calculate the additional charge is as follows. The following patterns are possible.

(1) Pattern 1
ISP-A: Calculate additional charge from received unnecessary data ISP-B: Calculate additional charge from received unnecessary data (2) Pattern 2
ISP-A: Calculate additional charge from received unnecessary data ISP-B: Calculate additional charge from transmitted unnecessary data (3) Pattern 3
ISP-A: Calculate additional charge from received unnecessary data ISP-B: Calculate additional charge from received and transmitted unnecessary data (4) Pattern 4
ISP-A: Calculate additional charge from received unnecessary data ISP-B: Do not calculate additional charge (5) Pattern 5
ISP-A: Calculate the additional charge from the transmitted unnecessary data ISP-B: Calculate the additional charge from the received unnecessary data (6) Pattern 6
ISP-A: Calculate additional charge from transmitted unnecessary data ISP-B: Calculate additional charge from transmitted unnecessary data (7) Pattern 7
ISP-A: Calculate the additional charge from the transmitted unnecessary data ISP-B: Calculate the additional charge from the received and transmitted unnecessary data (8) Pattern 8
ISP-A: Additional charge is calculated from unnecessary data transmitted ISP-B: Additional charge is not calculated (9) Pattern 9
ISP-A: Calculate additional charge from received and transmitted unnecessary data ISP-B: Calculate additional charge from received unnecessary data (10) Pattern 10
ISP-A: Calculate additional charge from received and transmitted unnecessary data ISP-B: Calculate additional charge from transmitted unnecessary data (11) Pattern 11
ISP-A: Calculate additional charge from received and transmitted unnecessary data ISP-B: Calculate additional charge from received and transmitted unnecessary data (12) Pattern 12
ISP-A: Additional charge is calculated from received and transmitted unnecessary data ISP-B: Additional charge is not calculated (13) Pattern 13
ISP-A: No additional charge is calculated ISP-B: Additional charge is calculated from received unnecessary data (14) Pattern 14
ISP-A: No additional charge is calculated
ISP-B: Calculate additional charges from transmitted unnecessary data (15) Pattern 15
ISP-A: Does not calculate additional charges ISP-B: Calculates additional charges from received and transmitted unnecessary data

  In the additional charge system described in the first embodiment, it is desirable to adopt the pattern 12 or 15 among the above patterns. For example, when ISP-A and ISP-B are connected by transit, and ISP-A charges ISP-B for a connection fee, pattern 12 is adopted so that ISP-A An additional charge can be charged to ISP-B together with a connection charge. Further, when ISP-B charges the connection fee to ISP-A, pattern 15 is adopted so that ISP-B can charge ISP-A together with the connection fee. Further, for example, even when ISP-A and ISP-B are connected by peering, the necessary additional charge can be calculated by adopting pattern 12 or 15. Next, it is desirable that pattern 1 or 6 is adopted among the above patterns for the additional charge system described in the first embodiment. When pattern 1 or 6 is adopted, a necessary additional charge can be calculated regardless of whether the connection form is peering or transit.

[Location of calculation device]
In the first embodiment, the calculation device 100 is arranged in the communication network provided by the ISP. However, the calculation device 100 may be arranged between the communication network and the communication network. In such a case, the calculation device 100 calculates the additional charge by monitoring data transmitted and received between the communication networks, and notifies the additional charge to one or both ISPs that provide the connected communication network.

[System configuration, etc.]
In addition, among the processes described in the above embodiment, all or a part of the processes described as being automatically performed can be manually performed, or the processes described as being performed manually can be performed. All or a part can be automatically performed by a known method.

In other words, the specific form of distribution / integration of each device is not limited to that shown in the figure, and all or a part thereof may be functionally or physically distributed or arbitrarily distributed in arbitrary units according to various loads or usage conditions. Can be integrated and configured. For example, the charging device 12 and the calculation device 100 illustrated in FIG. 1 may be integrated. For example, the determination unit 131 and the calculation unit 132 illustrated in FIG. 3 may be integrated. Further, for example, the determination unit 131 and the calculation unit 132 in the calculation device 100 illustrated in FIG. 3 may be included in the service providing device 11 and the billing device 12 without the calculation device 100. In such a case, the calculation device 100 stores the number of spam mails calculated by the service providing device 11 or the like.
