Description

本発明は、ユーザによるパケットの通信量をパケット通過箇所によらず測定できる通信量測定装置に関する。   The present invention relates to a communication amount measuring apparatus capable of measuring a packet communication amount by a user regardless of a packet passage location.

近年においては、インターネット、ブロードバンド技術の発展や、アプリケーションの多様化によって、ユーザ１人当たりの通信量が増大し、通信網に多大な負荷が掛かるようになっている。中でも一部のユーザが大量のパケットを送受信する場合があり、よって、ユーザの通信量を測定し、必要に応じて使用制限を行う運用が実施されている。   In recent years, with the development of the Internet and broadband technologies and the diversification of applications, the amount of communication per user has increased, and a great load has been placed on the communication network. Among them, some users may transmit and receive a large amount of packets, and therefore, an operation is performed in which a user's communication amount is measured and usage is restricted as necessary.

また、ユーザニーズの多様化により、通信量を予め制限し安価な料金で提供しているサービスもあり、これはユーザ毎に通信量を測定することによって実現されている。   In addition, due to diversification of user needs, there is also a service that restricts the amount of communication in advance and provides it at an inexpensive fee, which is realized by measuring the amount of communication for each user.

従来の通信量測定は、まず、通信網内のゲートウェイ装置に通信量を測定する機能を配備し、ユーザの端末がゲートウェイ装置に対して接続要求を行う際の認証処理と連携することにより、ユーザの端末が送受信するパケットのＩＰアドレスを特定する。そして、ユーザのパケットがゲートウェイ装置を通過するよう通信網を設計し、ゲートウェイ装置において、特定したＩＰアドレスの通信量を測定する。   In the conventional traffic volume measurement, first, a function for measuring the traffic volume is provided to the gateway device in the communication network, and the user terminal cooperates with an authentication process when a connection request is made to the gateway device. The IP address of the packet transmitted / received by the terminal is specified. Then, the communication network is designed so that the user's packet passes through the gateway device, and the communication amount of the specified IP address is measured in the gateway device.

しかし、多様化する通信網やユーザの利用形態によっては、認証処理と連携できない場合や、パケットがゲートウェイ装置を通過しない場合がある。そもそもパケットの通信量に応じて課金する前提となっていない通信網においてはゲートウェイ装置が通信量を測定する機能を有していない場合もある。   However, depending on the diversified communication networks and user usage patterns, there are cases in which cooperation with authentication processing cannot be performed or packets do not pass through the gateway device. In the first place, in a communication network that is not predicated on charging according to the amount of packet traffic, the gateway device may not have a function for measuring the traffic volume.

3GPP TS 23.203 V8.6.0 "Policy and charging control architecture" Jun.2009.3GPP TS 23.203 V8.6.0 "Policy and charging control architecture" Jun.2009.

本発明は、上記の課題に鑑みてなされたものであり、その目的とするところは、ユーザによるパケットの通信量をパケット通過箇所によらず測定できる通信量測定装置を提供することにある。   The present invention has been made in view of the above problems, and an object of the present invention is to provide a traffic measurement device that can measure the traffic of a packet by a user regardless of the packet passage location.

上記の課題を解決するために、本発明は、ＩＰｖ６パケットが通過する通信網における通信量を測定する通信量測定装置であって、測定開始命令を受信したら、当該測定開始命令内のＩＰｖ６Ｐｒｅｆｉｘについて通信量を測定し、当該ＩＰｖ６Ｐｒｅｆｉｘ毎に当該通信量を記憶させる通信量測定部と、外部からＩＰｖ６Ｐｒｅｆｉｘおよび、当該ＩＰｖ６Ｐｒｅｆｉｘを含むＩＰｖ６パケットを送信させるユーザを示すユーザＩＤを含むサービスオーダを受信し、当該ＩＰｖ６Ｐｒｅｆｉｘ、当該ユーザＩＤおよび、測定開始命令が送信されたか否かを示す状態フラグを対応づけて記憶させるサービスオーダ受付部と、前記サービスオーダ受付部にアクセスし、測定開始命令が送信されていないことを示す状態フラグを検索し、当該状態フラグに対応するＩＰｖ６Ｐｒｅｆｉｘを読み出し、当該ＩＰｖ６Ｐｒｅｆｉｘを含む測定開始命令を、前記各通信量測定部に送信するとともに、前記測定開始命令を送信したことを示すように当該状態フラグを更新する測定開始命令送信部と、前記各通信量測定部から、当該通信量測定部における通信量を含む測定結果ファイルを受信し、当該測定結果ファイル内のＩＰｖ６Ｐｒｅｆｉｘごとに、当該測定結果ファイルから当該ＩＰｖ６Ｐｒｅｆｉｘについて測定された通信量を読み出し、当該ＩＰｖ６Ｐｒｅｆｉｘ、当該通信量および、合計通信量が計算されたか否かを示す集計フラグを記憶させる測定結果収集部と、前記測定結果収集部にアクセスし、ＩＰｖ６Ｐｒｅｆｉｘごとに、合計通信量が計算されていないことを示す集計フラグを検索し、検索された全ての通信量を合計した合計通信量を計算し、当該ＩＰｖ６Ｐｒｅｆｉｘおよび、当該合計通信量を記憶させる通信量集計部とを備えることを特徴とする。   In order to solve the above-described problem, the present invention is a communication volume measuring apparatus for measuring a traffic volume in a communication network through which an IPv6 packet passes. When a measurement start command is received, communication is performed for IPv6 Prefix in the measurement start command. An IPv6 Prefix and a service order including a user ID indicating a user who transmits an IPv6 Prefix and an IPv6 packet including the IPv6 Prefix from outside, and receives the IPv6 Prefix. The service order reception unit that stores the user ID and a status flag indicating whether or not the measurement start command is transmitted in association with each other, and accesses the service order reception unit, and the measurement start command is not transmitted. Search for the status flag to indicate the status Reads IPv6Prefix corresponding to the lag, transmits a measurement start command including the IPv6Prefix to each of the traffic measurement units, and transmits a measurement start command to update the state flag to indicate that the measurement start command has been transmitted. And a communication result measured for the IPv6Prefix from the measurement result file for each IPv6Prefix in the measurement result file for each IPv6Prefix in the measurement result file. A measurement result collection unit that reads the amount, stores the IPv6 Prefix, the communication amount, and a total flag indicating whether or not the total communication amount is calculated; and accesses the measurement result collection unit, and determines the total communication amount for each IPv6 Prefix. An aggregation flag indicating that has not been calculated Searching, calculates the total traffic which is the sum of all the traffic that is retrieved, the IPv6Prefix and, characterized in that it comprises a traffic count unit for storing the total traffic.

本発明の通信量測定装置によれば、ユーザによるパケットの通信量をパケット通過箇所によらず測定できる。   According to the traffic measuring device of the present invention, it is possible to measure the packet traffic by a user regardless of the packet passage location.

本実施の形態に係る通信量測定装置の概略構成および通信量の測定対象である通信網の一例を示す図である。It is a figure which shows an example of the schematic structure of the communication amount measuring apparatus which concerns on this Embodiment, and the communication network which is a measuring object of communication amount. 通信量測定装置の詳細構成および動作の流れを示す図である。It is a figure which shows the detailed structure and flow of operation | movement of a communication amount measuring apparatus.

以下、本発明の実施の形態について図面を参照して説明する。   Hereinafter, embodiments of the present invention will be described with reference to the drawings.

図１に示すように、本実施の形態に係る通信量測定装置１は、例えば、ＩＰｖ６パケットが通過する通信網に設けられた光分岐装置３１を通過するＩＰｖ６パケットのデータ量である通信量を測定し、これをＩＰｖ６Ｐｒｅｆｉｘごとに合計、つまり集計するものである。   As shown in FIG. 1, the traffic measuring device 1 according to the present embodiment, for example, determines the traffic that is the data amount of the IPv6 packet that passes through the optical branching device 31 provided in the communication network through which the IPv6 packet passes. This is measured and totaled for each IPv6 Prefix, that is, totaled.

図１において、加入者端末２１とインターネット網２００の間で送受信されるＩＰｖ６パケットは、加入者収容ルータ２０とコアネットワーク１００のコアルータ１０１とゲートウェイ装置３０を通過する。ある加入者端末２１から送信されたＩＰｖ６パケットは、コアネットワーク１００の状態如何では、どのゲートウェイ装置３０でも通過しうる。また、ＩＰｖ６パケットは、ゲートウェイ装置３０でなく、エッジルータ４０を通過して、アプリケーションサーバ３０１に送信されるというような構成となっている場合もある。   In FIG. 1, IPv6 packets transmitted and received between the subscriber terminal 21 and the Internet network 200 pass through the subscriber accommodating router 20, the core router 101 of the core network 100, and the gateway device 30. An IPv6 packet transmitted from a certain subscriber terminal 21 can pass through any gateway device 30 depending on the state of the core network 100. The IPv6 packet may be configured to be transmitted to the application server 301 through the edge router 40 instead of the gateway device 30.

光分岐装置３１は、例えば、コアルータ１０１とゲートウェイ装置３０の間に挿入され、また、コアルータ１０１とエッジルータ４０の間にも挿入される。   For example, the optical branching device 31 is inserted between the core router 101 and the gateway device 30 and also inserted between the core router 101 and the edge router 40.

各光分岐装置３１は、挿入箇所を通過する光信号（ＩＰｖ６パケット）をゲートウェイ装置３０やエッジルータ４０の方向と通信量測定装置１の方向に分岐させ、通信量測定装置１は、後者の光信号（ＩＰｖ６パケット）について通信量を測定し、集計する。   Each optical branching device 31 branches an optical signal (IPv6 packet) passing through the insertion point in the direction of the gateway device 30 or the edge router 40 and the direction of the traffic measuring device 1, and the traffic measuring device 1 The traffic is measured and aggregated for the signal (IPv6 packet).

図１に示すように、通信量測定装置１は、各光分岐装置３１からＩＰｖ６パケットを受信し、通信量を測定する通信量測定部１１ａ、１１ｂ、１１ｃと、顧客管理システム（図示せず）からサービスオーダを受信するサービスオーダ受付部１２と、サービスオーダ受付部１２にアクセスし、必要となったら各通信量測定部１１ａ、１１ｂ、１１ｃに測定開始命令を送信する測定開始命令送信部１３と、各通信量測定部１１ａ、１１ｂ、１１ｃから測定結果ファイルを受信する測定結果収集部１４と、測定結果収集部１４から通信量を取得し、集計する通信量集計部１５とを備える。   As shown in FIG. 1, the traffic measuring device 1 receives IPv6 packets from each optical branching device 31, and measures the traffics measuring units 11a, 11b, 11c, and a customer management system (not shown). A service order receiving unit 12 that receives a service order from the network, a service order receiving unit 12 that accesses the service order receiving unit 12, and transmits a measurement start command to each of the traffic volume measuring units 11a, 11b, and 11c when necessary. The communication amount measuring unit 11a, 11b, 11c includes a measurement result collecting unit 14 that receives the measurement result file, and the communication amount collecting unit 15 that acquires the communication amount from the measurement result collecting unit 14 and totals it.

図２に示すように、各通信量測定部１１ａ、１１ｂ、１１ｃは、ＩＰｖ６Ｐｒｅｆｉｘごとに、ＩＰｖ６ＰｒｅｆｉｘおよびＩＰｖ６Ｐｒｅｆｉｘを含むＩＰｖ６パケットの通信量を含むレコードが記憶される通信量記録テーブル１１１を備える。   As shown in FIG. 2, each of the traffic volume measuring units 11a, 11b, and 11c includes a traffic volume recording table 111 in which a record including the traffic volume of an IPv6 packet including IPv6 Prefix and IPv6 Prefix is stored for each IPv6 Prefix.

サービスオーダ受付部１２は、サービスオーダに含まれるＩＰｖ６Ｐｒｅｆｉｘ、ＩＰｖ６Ｐｒｅｆｉｘを含むＩＰｖ６パケットを送信させるユーザを示すユーザＩＤおよび、ＩＰｖ６Ｐｒｅｆｉｘについて測定開始命令が送信されたか否かを示す状態フラグを含むレコードが記憶されるサービスオーダ管理データベース１２１を備える。   The service order reception unit 12 stores records including IPv6 Prefix included in the service order, a user ID indicating a user who transmits an IPv6 packet including IPv6 Prefix, and a status flag indicating whether a measurement start command is transmitted for IPv6 Prefix. The service order management database 121 is provided.

測定結果収集部１４は、ＩＰｖ６Ｐｒｅｆｉｘ、ＩＰｖ６Ｐｒｅｆｉｘについて測定された通信量および、通信量について合計通信量が計算されたか否かを示す集計フラグを含むレコードが記憶される通信量管理データベース１４１を備える。   The measurement result collection unit 14 includes a communication amount management database 141 in which a record including a communication amount measured for IPv6 Prefix and IPv6 Prefix and a total flag indicating whether or not the total communication amount has been calculated for the communication amount is stored.

通信量集計部１５は、各ＩＰｖ６Ｐｒｅｆｉｘにつき、ＩＰｖ６Ｐｒｅｆｉｘおよび、ＩＰｖ６Ｐｒｅｆｉｘについて測定された通信量を合計した合計通信量を含むレコードが記憶される集計結果データベース１５１を備える。   The communication amount totaling unit 15 includes an aggregation result database 151 in which records including the total communication amount obtained by summing the IPv6 Prefix and the communication amount measured for the IPv6 Prefix are stored for each IPv6 Prefix.

サービスオーダ受付部１２は、顧客管理システムから、ＩＰｖ６Ｐｒｅｆｉｘおよび、ＩＰｖ６Ｐｒｅｆｉｘを含むＩＰｖ６パケットを送信させるユーザを示すユーザＩＤを含むサービスオーダが逐次送信されるので、これを受信したなら、サービスオーダ管理データベース１２１に対し、サービスオーダ内のＩＰｖ６Ｐｒｅｆｉｘ、ユーザＩＤおよび、測定開始命令が送信されていないことを示す状態フラグを含むレコードを記憶させる。   Since the service order reception unit 12 sequentially transmits a service order including a user ID indicating an IPv6 Prefix and a user who transmits an IPv6 packet including the IPv6 Prefix from the customer management system, if the service order is received, the service order management database 121 On the other hand, a record including an IPv6 Prefix in the service order, a user ID, and a status flag indicating that a measurement start command has not been transmitted is stored.

測定開始命令送信部１３は、例えば、定期的にサービスオーダ受付部１２にアクセスし、サービスオーダ管理データベース１２１から、測定開始命令が送信されていないことを示す状態フラグを含むレコードを検索し、レコードからＩＰｖ６Ｐｒｅｆｉｘを読み出し、当該ＩＰｖ６Ｐｒｅｆｉｘを含む測定開始命令を、各通信量測定部１１ａ、１１ｂ、１１ｃに送信するとともに、測定開始命令を送信したことを示すように状態フラグを更新する。   For example, the measurement start command transmission unit 13 periodically accesses the service order reception unit 12 and searches the service order management database 121 for a record including a status flag indicating that no measurement start command is transmitted. The IPv6Prefix is read from the information, and a measurement start command including the IPv6Prefix is transmitted to each of the traffic measurement units 11a, 11b, and 11c, and the status flag is updated to indicate that the measurement start command is transmitted.

各通信量測定部１１ａ、１１ｂ、１１ｃは、測定開始命令を受信したなら、測定開始命令内のＩＰｖ６Ｐｒｅｆｉｘについて通信量の測定を開始する。つまり、各通信量測定部１１ａ、１１ｂ、１１ｃは、光分岐装置３１からＩＰｖ６パケットを受信したなら、ＩＰｖ６パケット内のＩＰｖ６Ｐｒｅｆｉｘが、測定開始命令内のＩＰｖ６Ｐｒｅｆｉｘに一致するか否かを判定し、一致したなら、ＩＰｖ６パケットのデータ量である通信量を計算する。また、各通信量測定部１１ａ、１１ｂ、１１ｃは、ＩＰｖ６Ｐｒｅｆｉｘごとに、例えば、予め定められた期間が経過したなら、ＩＰｖ６Ｐｒｅｆｉｘおよび、期間におけるトータルの通信量（以下、単に通信量という）を含むレコードを通信量記録テーブル１１１に記憶させる。   When receiving the measurement start command, each traffic measurement unit 11a, 11b, 11c starts measuring the traffic for IPv6 Prefix in the measurement start command. That is, when the traffic measurement units 11a, 11b, and 11c receive an IPv6 packet from the optical branching device 31, they determine whether the IPv6Prefix in the IPv6 packet matches the IPv6Prefix in the measurement start command. If so, the communication amount that is the data amount of the IPv6 packet is calculated. Further, each traffic volume measuring unit 11a, 11b, 11c, for each IPv6 Prefix, for example, if a predetermined period has elapsed, records including IPv6 Prefix and the total traffic volume during the period (hereinafter simply referred to as traffic volume). Is stored in the communication amount recording table 111.

測定結果収集部１４は、各通信量測定部１１ａ、１１ｂ、１１ｃに要求して、通信量記録テーブル１１１の内容を示す測定結果ファイルを送信させ、これを受信する。   The measurement result collection unit 14 requests each of the traffic volume measurement units 11a, 11b, and 11c to transmit a measurement result file indicating the contents of the traffic volume recording table 111 and receives it.

測定結果ファイルは、通信量記録テーブル１１１の内容を示すものであるから、つまり、ＩＰｖ６Ｐｒｅｆｉｘごとに、ＩＰｖ６ＰｒｅｆｉｘおよびＩＰｖ６Ｐｒｅｆｉｘを含むＩＰｖ６パケットの通信量を含むレコードを有する。   Since the measurement result file indicates the contents of the communication amount recording table 111, that is, each IPv6 Prefix has a record including the communication amount of an IPv6 packet including IPv6 Prefix and IPv6 Prefix.

測定結果収集部１４は、測定結果ファイル内のレコードごとに、つまりＩＰｖ６Ｐｒｅｆｉｘごとに、レコードからＩＰｖ６Ｐｒｅｆｉｘおよび、ＩＰｖ６Ｐｒｅｆｉｘについて測定された通信量を読み出し、通信量管理データベース１４１に対し、ＩＰｖ６Ｐｒｅｆｉｘ、通信量、合計通信量が計算されていないことを示す集計フラグおよび、送信元の通信量測定部を示す通信量測定部ＩＤを含むレコードを記憶させる。   The measurement result collection unit 14 reads out the traffic volume measured for the IPv6 Prefix and the IPv6 Prefix from the record for each record in the measurement result file, that is, for each IPv6 Prefix, and sends the IPv6 Prefix, the traffic volume, and the total to the traffic management database 141. A record including an aggregation flag indicating that the communication amount has not been calculated and a communication amount measuring unit ID indicating the transmission amount measuring unit of the transmission source is stored.

通信量集計部１５は、例えば上記のように通信量管理データベース１４１が更新された後、測定結果収集部１４にアクセスし、通信量管理データベース１４１からＩＰｖ６Ｐｒｅｆｉｘごとに、ＩＰｖ６Ｐｒｅｆｉｘおよび、合計通信量が計算されていないことを示す集計フラグを含むレコードを検索し、検索された全てのレコード内の通信量を合計した合計通信量を計算し、集計結果データベース１５１に対し、ＩＰｖ６Ｐｒｅｆｉｘおよび、合計通信量を含むレコードを記憶させる。   For example, after the traffic volume management database 141 is updated as described above, the traffic volume totaling unit 15 accesses the measurement result collection unit 14 and calculates the IPv6 Prefix and the total traffic volume from the traffic volume management database 141 for each IPv6 Prefix. Search for a record including a total flag indicating that it has not been performed, and calculate a total communication amount by summing the communication amount in all the searched records, and include IPv6 Prefix and the total communication amount for the total result database 151 Remember the record.

図では、１つのＩＰｖ６Ｐｒｅｆｉｘを例とし、そのＩＰｖ６Ｐｒｅｆｉｘについて、通信量測定分周１１ａで測定した通信量を「●●●」で示し、通信量測定分周１１ｂで測定した通信量を「○○」で示し、通信量測定分周１１ｃで測定した通信量を「△△△」で示し、合計通信量を「□□□□（＝●●●＋○○＋△△△）」で示す。   In the figure, one IPv6 Prefix is taken as an example, and for that IPv6 Prefix, the traffic volume measured by the traffic volume measurement division 11a is indicated by “●●●”, and the traffic volume measured by the traffic volume measurement division 11b is “◯◯”. The traffic volume measured by the traffic volume measurement division 11c is indicated by “ΔΔΔ”, and the total traffic volume is indicated by “□□□□ (= ●●● + ◯◯ + ΔΔΔ)”.

通信量集計部１５は、また、合計通信量が計算されたことを示すように集計フラグを更新する。   The communication amount totaling unit 15 also updates the aggregation flag to indicate that the total communication amount has been calculated.

以上のように、本実施の形態の通信量測定装置１によれば、ユーザによるパケット（ＩＰｖ６パケット）の通信量をＩＰｖ６Ｐｒｅｆｉｘごとに測定でき、また、パケットが通過すると分かっている箇所に光分岐装置３１を設ければよいので、パケット通過箇所によらず通信量を測定できる。よって、ゲートウェイ装置を通過するパケットで通信量を測定しなくてもよく、多様化する通信網においても通信量を測定できる。また、ゲートウェイ装置における認証処理との連携も不要となる。   As described above, according to the traffic volume measuring apparatus 1 of the present embodiment, the traffic volume of a packet (IPv6 packet) by a user can be measured for each IPv6 Prefix, and an optical branching device is installed at a location where the packet is known to pass. Therefore, the communication amount can be measured regardless of the packet passage location. Therefore, it is not necessary to measure the communication amount with a packet passing through the gateway device, and the communication amount can be measured even in a diversified communication network. In addition, cooperation with authentication processing in the gateway device is not required.

なお、本実施の形態では、光分岐装置３１の設置箇所を３箇所としたが、これに限らず、任意の箇所に光分岐装置３１を設置してよい。また、光信号を分岐させるのでなく、電気信号によるＩＰｖ６パケットを分岐させる装置を光分岐装置３１に代えて設けてもよい。   In the present embodiment, the number of places where the optical branching device 31 is installed is three. However, the present invention is not limited to this, and the optical branching device 31 may be installed at an arbitrary location. Further, instead of branching the optical signal, a device for branching the IPv6 packet by the electric signal may be provided in place of the optical branching device 31.

また、通信量測定部は、光分岐装置３１等の設置箇所に合わせて設ければよく、３個に限らない。   Moreover, what is necessary is just to provide the traffic measurement part according to the installation location of the optical branching device 31, etc., and is not restricted to three pieces.
