Description

本発明は、運営会社が異なる複数の通信ネットワークにそれぞれ所属する２つの装置間（ポイント・ツー・ポイント）で装置固有ＩＤを用いた監視信号（監視フレーム、監視パケット）を流通させて通信の正常性を確認する場合でも、各装置の装置固有ＩＤが他社へ流出しないように前記監視信号をネットワーク単位で終端するための技術に関する。 In the present invention, normal communication is performed by distributing a monitoring signal (monitoring frame, monitoring packet) using a device unique ID between two devices (point-to-point) each belonging to a plurality of communication networks with different operating companies. The present invention also relates to a technique for terminating the monitoring signal in units of networks so that the device unique ID of each device does not flow out to other companies even when confirming the performance.

従来より、通信ネットワークを構成する任意の２つの装置、例えば任意の２つの終端装置間の通信の正常性を確認する方法として、当該２つの終端装置間で、機種情報やベンダ情報等の装置固有の情報を含む装置固有ＩＤ（例えばイーサネット（登録商標）フレームのＭＡＣアドレス）を用いた監視信号を流通させる方法がある。 Conventionally, as a method for confirming the normality of communication between any two devices constituting a communication network, for example, any two terminal devices, the device information such as model information and vendor information between the two terminal devices is unique. There is a method for distributing a monitoring signal using a device unique ID (for example, the MAC address of an Ethernet (registered trademark) frame) including the above information.

この方法は、通信ネットワークを管理するネットワーク管理装置により、一方の終端装置から当該一方の終端装置の装置固有ＩＤを発信元ＩＤとし且つ他方の終端装置の装置固有ＩＤを受信先ＩＤとする監視信号を発出させるとともに、他方の終端装置に前記一方の終端装置の装置固有ＩＤを発信元ＩＤとして保持させ、当該他方の終端装置において前記保持した装置固有ＩＤを発信元ＩＤとし且つ自身の装置固有ＩＤを受信先ＩＤとして含む監視信号が一定時間受信できなかったり、自身の装置固有ＩＤを受信先ＩＤとして受信した監視信号の発信元ＩＤが前記保持した装置固有ＩＤと異なる場合に警報を上げさせるものであった（特許文献１、２参照）。 This method uses a network management device that manages a communication network to monitor a signal from one terminal device with the device unique ID of the one terminal device as a source ID and the device unique ID of the other terminal device as a destination ID. And the other terminal device holds the device unique ID of the one terminal device as a transmission source ID, and the device unique ID held in the other terminal device is used as the transmission source ID and its own device unique ID. That raises an alarm if the monitoring signal containing the receiver ID cannot be received for a certain period of time, or if the sender ID of the monitoring signal received using its own device unique ID is different from the held device unique ID (See Patent Documents 1 and 2).

しかし、この方法では、各終端装置が運営会社の異なる複数の通信ネットワークにそれぞれ所属している場合、例えば一方の終端装置がネットワーク管理装置も運営する会社（自社）の通信ネットワーク（以下、自ネットワーク）に所属し、他方の終端装置が自ネットワークと所定の接続点を通じて相互に接続された他社の通信ネットワーク（他ネットワーク）に所属している場合、自ネットワークを構成する一方の終端装置の装置固有ＩＤを当該他ネットワークに公開することになり、この装置固有ＩＤから自ネットワークを構成する装置の機種情報やベンダ情報が他社に流出（例えばイーサネット（登録商標）フレームのＭＡＣアドレスは一般にベンダ情報を含んでいるため、ＭＡＣアドレスからベンダ情報が流出）してしまうという欠点があった。 However, in this method, when each terminal device belongs to a plurality of communication networks with different operating companies, for example, the communication network of the company (in-house) in which one terminal device also operates the network management device (hereinafter referred to as its own network). ), And the other terminal device belongs to another company's communication network (other network) that is connected to the local network through a predetermined connection point. The ID is disclosed to the other network, and the model information and vendor information of the devices constituting the network are leaked to other companies from this device unique ID (for example, the MAC address of the Ethernet (registered trademark) frame generally includes the vendor information). The vendor information leaks from the MAC address) There was.

そこで、他ネットワークとの接続点近傍に装置固有ＩＤを知られても良い中継ネットワーク装置を設置し、ここで監視信号（他ネットワークへの監視信号および他ネットワークからの監視信号）を終端する方法が考えられる。しかし、これを実現するには、監視信号の流通区間（監視区間）を自ネットワーク分と他ネットワーク分とに適切に分割した上で、他ネットワークの監視区間における監視信号の流通に関しては当該他ネットワーク（の運営会社）に委ねるための連絡を行う必要があり、特に多数の通信ネットワークと接続されている場合に困難な作業になるという問題があった。 Therefore, there is a method of installing a relay network device in which the device unique ID may be known in the vicinity of a connection point with another network, and terminating a monitoring signal (a monitoring signal to another network and a monitoring signal from another network) here. Conceivable. However, in order to realize this, the monitoring signal distribution section (monitoring section) is appropriately divided into the own network portion and the other network portion, and the monitoring signal distribution in the monitoring section of the other network is related to the other network. There is a problem that it is difficult to make contact with a large number of communication networks, especially when it is connected to a large number of communication networks.

本発明は、複数のネットワークに跨る監視信号をネットワーク単位に終端させて流通させる場合の監視区間の分割や他社への連絡を自動化することを目的とする。 An object of the present invention is to automate the division of monitoring sections and the communication with other companies in the case where monitoring signals across a plurality of networks are terminated and distributed in units of networks.

以下、本発明を図面に基づいて詳細に説明する。 Hereinafter, the present invention will be described in detail with reference to the drawings.

図１は本発明のネットワーク管理装置、ここでは１０とともにその監視対象ネットワークの全体を示すもので、ネットワーク管理装置１０本来の管理対象である自社の通信ネットワーク（自ネットワーク）Ａおよびネットワーク管理装置１０本来の管理対象でないが装置固有ＩＤを用いた監視信号の流通先となる装置を含む他社の通信ネットワーク（他ネットワーク）Ｂ１，Ｂ２から構成され、自ネットワークＡと他ネットワークＢ１，Ｂ２とはそれぞれ所定の接続点Ｃ１，Ｃ２において接続されているものとする。 FIG. 1 shows a network management apparatus according to the present invention, here, the entire network to be monitored together with 10. The network management apparatus 10 itself and its own communication network (own network) A and network management apparatus 10 Is composed of communication networks (other networks) B1 and B2 of other companies including a device that is a distribution destination of the monitoring signal using the device unique ID, and the own network A and the other networks B1 and B2 are respectively predetermined. It is assumed that the connection points C1 and C2 are connected.

ここで、自ネットワークＡは他ネットワークＢ１，Ｂ２との接続点Ｃ１，Ｃ２近傍にそれぞれ設置された装置固有ＩＤを開示可能な中継ネットワーク装置Ｄ１，Ｄ２とともに、装置固有ＩＤを開示不可な終端装置Ｄ５，Ｄ６，Ｄ７，Ｄ８および装置固有ＩＤを開示不可な中継装置Ｄ３，Ｄ４から構成され、また、他ネットワークＢ１，Ｂ２はそれぞれ装置固有ＩＤを開示不可な終端装置Ｄ９，Ｄ１０を備えているものとする。なお、各装置Ｄ１〜Ｄ１０にはそれぞれ、装置固有ＩＤとは別の、いずれの通信ネットワークに対しても開示可能な装置ＩＤ、ここではｄ１〜ｄ１０が予め付与されているものとする。 Here, the own network A, together with the relay network devices D1 and D2 capable of disclosing the device unique IDs installed near the connection points C1 and C2 with the other networks B1 and B2, respectively, the terminating device D5 that cannot disclose the device unique ID. , D6, D7, D8 and relay devices D3, D4 whose device unique IDs cannot be disclosed, and the other networks B1, B2 have terminal devices D9, D10 whose device unique IDs cannot be disclosed, respectively. To do. It is assumed that each of the devices D1 to D10 is previously assigned a device ID that can be disclosed to any communication network, which is different from the device unique ID, here d1 to d10.

ネットワーク管理装置１０では、後述するように前記装置ＩＤによる監視指示オーダを自社向け設定オーダ、または自社向け設定オーダおよび他社向け設定オーダに分割し、自社向け設定オーダを自社オーダ処理部Ｅへ、また他社向け設定オーダをオーダ受信システムＦ１，Ｆ２へ転送する。 As will be described later, the network management device 10 divides the monitoring instruction order based on the device ID into the in-house setting order, or the in-house setting order and the in-house setting order, and the in-house setting order is sent to the in-house order processing unit E. Transfer setting orders for other companies to order receiving systems F1 and F2.

自社オーダ処理部Ｅおよびオーダ受信システムＦ１，Ｆ２はそれぞれ、自ネットワークＡおよび他ネットワークＢ１，Ｂ２に所属し、ネットワーク管理装置１０から転送される設定オーダに含まれる装置ＩＤを装置固有ＩＤに翻訳し、所属ネットワークに当該装置固有ＩＤを用いた監視信号を流通させて通信の正常性を確認させる機能を有するものとする。 The in-house order processing unit E and the order receiving systems F1 and F2 belong to the own network A and other networks B1 and B2, respectively, and translate the device ID included in the set order transferred from the network management device 10 into the device unique ID. It is assumed that a monitoring signal using the device unique ID is distributed to the affiliated network to confirm the normality of communication.

なお、自社オーダ処理部Ｅおよびオーダ受信システムＦ１，Ｆ２はそれぞれ、その所属ネットワークを構成する各装置の装置固有ＩＤを保持している外、接続点近傍の別のネットワークの中継ネットワーク装置の装置固有ＩＤを保持、ここではオーダ受信システムＦ１では中継ネットワーク装置Ｄ１の装置固有ＩＤを保持し、また、オーダ受信システムＦ２では中継ネットワーク装置Ｄ２の装置固有ＩＤを保持しているものとする。 The in-house order processing unit E and the order receiving systems F1 and F2 each hold the device unique ID of each device constituting the network to which the company belongs, and also the device unique of the relay network device of another network near the connection point. In this example, it is assumed that the order receiving system F1 holds the device unique ID of the relay network device D1, and the order receiving system F2 holds the device unique ID of the relay network device D2.

図２は本発明のネットワーク管理装置１０の実施の形態の一例を示すもので、本発明のネットワーク管理装置１０は、ネットワーク所属テーブル１１と、ネットワーク接続テーブル１２と、監視オーダ受付部１３と、ＩＤ判別部１４と、設定オーダ変換部１５と、自社向けオーダ転送部１６と、他社向けオーダ転送部１７とから構成されている。 FIG. 2 shows an example of an embodiment of the network management apparatus 10 of the present invention. The network management apparatus 10 of the present invention includes a network affiliation table 11, a network connection table 12, a monitoring order receiving unit 13, an ID The determination unit 14 includes a set order conversion unit 15, an in-house order transfer unit 16, and an other company's order transfer unit 17.

ネットワーク所属テーブル１１は、自ネットワークＡおよび他ネットワークＢ１，Ｂ２を構成する各装置Ｄ１〜Ｄ１０の装置ＩＤと当該各装置Ｄ１〜Ｄ１０が所属する通信ネットワークとを対応させて保持してなるもので、図３にその一例を示す。図３では装置ＩＤがｄ１〜ｄ８の装置が自ネットワークＡに所属し、ｄ９の装置が他ネットワークＢ１に所属し、ｄ１０の装置が他ネットワークＢ２に所属していることが示されている。 The network affiliation table 11 holds the device IDs of the devices D1 to D10 constituting the own network A and the other networks B1 and B2 and the communication networks to which the devices D1 to D10 belong. An example is shown in FIG. FIG. 3 shows that devices with device IDs d1 to d8 belong to the own network A, device d9 belongs to another network B1, and device d10 belongs to another network B2.

ネットワーク接続テーブル１２は、自ネットワークＡと接続する他ネットワークＢ１，Ｂ２ごとにその接続点近傍に設置された中継ネットワーク装置の装置ＩＤおよび当該他ネットワークＢ１，Ｂ２のオーダ転送先（の情報）を保持してなるもので、図４にその一例を示す。図４では他ネットワークＢ１の接続点近傍の中継ネットワーク装置の装置ＩＤがｄ１、オーダ転送先がオーダ受信システムＦ１であり、また、他ネットワークＢ２の接続点近傍の中継ネットワーク装置の装置ＩＤがｄ２、オーダ転送先がオーダ受信システムＦ２であることが示されている。 The network connection table 12 holds the device ID of the relay network device installed in the vicinity of the connection point for each of the other networks B1 and B2 connected to the own network A and the order transfer destination (information) of the other networks B1 and B2. One example is shown in FIG. In FIG. 4, the device ID of the relay network device near the connection point of the other network B1 is d1, the order transfer destination is the order receiving system F1, and the device ID of the relay network device near the connection point of the other network B2 is d2.

ここで、監視指示オーダとは、装置固有ＩＤを用いた監視信号による監視区間の始点および終点をそれぞれ前記装置ＩＤで指定する始点ＩＤおよび終点ＩＤの組を少なくとも１つ含むもので、図５にその一例を示す。ここで監視指示オーダ＃１は始点ＩＤおよび終点ＩＤとしてｄ５およびｄ９の組を含み、監視指示オーダ＃２は監視区間として始点ＩＤ＝ｄ５および終点ＩＤ＝ｄ１０の組と、始点ＩＤ＝ｄ７および終点ＩＤ＝ｄ１０の組とを含むことが示されている。このように、１つの監視指示オーダが複数の監視区間の組を保持したり、複数の組で同一の始点ＩＤまたは終点ＩＤを指定することを妨げない。 Here, the monitoring instruction order includes at least one set of a starting point ID and an ending point ID each specifying a starting point and an ending point of a monitoring section by a monitoring signal using a device unique ID by the device ID. An example is shown. Here, the monitoring instruction order # 1 includes a set of d5 and d9 as the start point ID and the end point ID, and the monitoring instruction order # 2 includes a set of the start point ID = d5 and the end point ID = d10, the start point ID = d7 and the end point as the monitoring section. It is shown that the set includes ID = d10. In this way, it does not prevent one monitoring instruction order from holding a plurality of sets of monitoring sections or designating the same start point ID or end point ID in a plurality of sets.

自社向けオーダ転送部１６は、設定オーダ変換部１５で生成された自社向け設定オーダを自ネットワークのオーダ処理部、即ち自社オーダ処理部Ｅに転送する。 The in-house order transfer unit 16 transfers the in-house setting order generated by the setting order conversion unit 15 to the order processing unit of the own network, that is, the in-house order processing unit E.

他社向けオーダ転送部１７は、設定オーダ変換部２５で生成された他社向け設定オーダを当該他社向け設定オーダ内に設定されたオーダ転送先、即ちオーダ受信システムＦ１，Ｆ２に転送する。 The other company order transfer unit 17 transfers the other company setting order generated by the setting order conversion unit 25 to the order transfer destination set in the other company setting order, that is, the order receiving systems F1 and F2.

以下、本ネットワーク管理装置１０の動作を例を挙げて説明する。 Hereinafter, the operation of the network management apparatus 10 will be described with an example.

まず、監視オーダ受付部１３は、図示しないキーボード等から直接入力され又は記憶媒体から読み出されて入力され又は通信媒体を介して他の装置等から入力された監視指示オーダ、例えば図５に示す監視指示オーダ＃１を受け付け、当該監視指示オーダ＃１の始点ＩＤ＝ｄ５および終点ＩＤ＝ｄ９をＩＤ判別部１４に渡す。 First, the monitoring order receiving unit 13 is a monitoring instruction order input directly from a not-shown keyboard or the like, or read and input from a storage medium, or input from another device or the like via a communication medium, for example, as shown in FIG. The monitoring instruction order # 1 is received, and the start point ID = d5 and the end point ID = d9 of the monitoring instruction order # 1 are passed to the ID determination unit 14.

ＩＤ判別部１４は、監視指示オーダ＃１の始点ＩＤおよび終点ＩＤが所属するネットワークをネットワーク所属テーブル１１から取得して判別、ここでは始点ＩＤ＝ｄ５の所属ネットワークとして自ネットワークＡ、終点ＩＤ＝ｄ９の所属ネットワークとして他ネットワークＢ１をネットワーク所属テーブル１１から取得し、始点ＩＤが自ネットワークに所属し、終点ＩＤが他ネットワークＢ１に所属すると判別する（ｓ１，ｓ２，ｓ３）。 The ID determination unit 14 acquires the network to which the start point ID and the end point ID of the monitoring instruction order # 1 belong from the network affiliation table 11, and in this case, the own network A and the end point ID = d9 as the affiliation network of the start point ID = d5. The other network B1 is acquired from the network affiliation table 11 as the affiliation network, and it is determined that the start point ID belongs to the own network and the end point ID belongs to the other network B1 (s1, s2, s3).

次に、設定オーダ変換部１５は、終点ＩＤの所属ネットワークに対応する中継ネットワーク装置の装置ＩＤおよびオーダ転送先をネットワーク接続テーブル１２から取得、ここでは所属ネットワークである他ネットワークＢ１に対応する中継ネットワーク装置の装置ＩＤとしてｄ１およびオーダ転送先としてオーダ受信システムＦ１をネットワーク接続テーブル１２から取得する（ｓ２１）。 Next, the set order conversion unit 15 acquires the device ID and the order transfer destination of the relay network device corresponding to the network to which the end point ID belongs from the network connection table 12, and here, the relay network corresponding to the other network B1 that is the network to which it belongs. D1 as the device ID of the device and the order receiving system F1 as the order transfer destination are acquired from the network connection table 12 (s21).

次に、設定オーダ変換部１５は、前記監視指示オーダの始点ＩＤを始点ＩＤとし且つ前記取得した中継ネットワーク装置の装置ＩＤを終点ＩＤとする自社向け設定オーダ、ここでは始点ＩＤ＝ｄ５、終点ＩＤ＝ｄ１の自社向け設定オーダと、前記取得した中継ネットワーク装置の装置ＩＤを始点ＩＤとし且つ前記監視指示オーダの終点ＩＤを終点ＩＤとし更に前記取得したオーダ転送先を転送先とする他社向け設定オーダ、ここでは始点ＩＤ＝ｄ１、終点ＩＤ＝ｄ９、転送先＝オーダ受信システムＦ１の他社向け設定オーダとを生成する（ｓ２２，ｓ２３）。 Next, the set order conversion unit 15 sets the start order ID of the monitoring instruction order as a start point ID and sets the device ID of the acquired relay network device as an end point ID. = D1 setting order for the company, and the setting ID for the other company having the device ID of the acquired relay network device as the start point ID, the end point ID of the monitoring instruction order as the end point ID, and the acquired order transfer destination as the transfer destination Here, the start point ID = d1, the end point ID = d9, and the transfer destination = set order for the other company of the order receiving system F1 are generated (s22, s23).

自社向けオーダ転送部１６は、設定オーダ変換部１５で生成された自社向け設定オーダを自社オーダ処理部Ｅに転送し、また、他社向けオーダ転送部１７は、設定オーダ変換部１５で生成された他社向け設定オーダを当該他社向け設定オーダ内に設定されたオーダ転送先、ここではオーダ受信システムＦ１に転送する。 The in-house order transferring unit 16 transfers the in-house setting order generated by the setting order converting unit 15 to the in-house order processing unit E, and the other company's order transferring unit 17 is generated by the setting order converting unit 15. The setting order for the other company is transferred to the order transfer destination set in the setting order for the other company, here the order receiving system F1.

なお、自社オーダ処理部Ｅでは、前述した自社向け設定オーダを受け取ると、その始点ＩＤ＝ｄ５および終点ＩＤ＝ｄ１をそれぞれ、対応する終端装置Ｄ５および中継ネットワーク装置Ｄ１の装置固有ＩＤに翻訳し、これらの装置固有ＩＤを用いた監視信号を自ネットワークＡに流通させて終端装置Ｄ５および中継ネットワーク装置Ｄ１間の通信の正常性を確認する。 When the company order processing unit E receives the above-described setting order for the company, it translates the start point ID = d5 and the end point ID = d1 into the device unique IDs of the corresponding terminal device D5 and relay network device D1, respectively. A monitoring signal using these device unique IDs is distributed to the own network A to check the normality of communication between the terminal device D5 and the relay network device D1.

また、オーダ受信システムＦ１では、前述した他社向け設定オーダを受け取ると、その始点ＩＤ＝ｄ１および終点ＩＤ＝ｄ９をそれぞれ、対応する中継ネットワーク装置Ｄ１および終端装置Ｄ９の装置固有ＩＤに翻訳し、これらの装置固有ＩＤを用いた監視信号を他ネットワークＢ１に流通させて中継ネットワーク装置Ｄ１および終端装置Ｄ９間の通信の正常性を確認する。 Further, when the order receiving system F1 receives the above-mentioned setting order for other companies, the start point ID = d1 and the end point ID = d9 are translated into the device unique IDs of the corresponding relay network device D1 and end device D9, respectively. The monitoring signal using the device unique ID is distributed to the other network B1, and the normality of communication between the relay network device D1 and the termination device D9 is confirmed.

更にまた、自社オーダ処理部Ｅおよびオーダ受信システムＦ１による確認結果（装置固有ＩＤは含まない。）については、必要に応じてネットワーク管理装置１０または別の装置にて収集し、監視指示オーダに対応する確認結果に変換するようにしても良い。 Furthermore, the confirmation results (not including the device unique ID) by the in-house order processing unit E and the order receiving system F1 are collected by the network management device 10 or another device as necessary, and correspond to the monitoring instruction order. It may be converted into a confirmation result.

このように、本実施の形態によれば、運営会社が異なる複数の通信ネットワークにそれぞれ所属する２つの装置間（ポイント・ツー・ポイント）で、機種情報やベンダ情報等の装置固有の情報を含む装置固有ＩＤを用いた監視信号を流通させて通信の正常性を確認する場合でも、監視信号の流通区間（監視区間）を自ネットワーク分と他ネットワーク分とに適切に分割し、装置固有ＩＤを他社に流出させないようにした上で、他ネットワークの監視区間における監視信号の流通に関しては当該他ネットワークの運営会社に連絡することができる。 Thus, according to the present embodiment, information unique to a device such as model information and vendor information is included between two devices (point-to-point) each belonging to a plurality of communication networks with different operating companies. Even when the monitoring signal using the device unique ID is distributed to check the normality of the communication, the monitoring signal distribution section (monitoring section) is appropriately divided into the own network portion and the other network portion, and the device unique ID is set. It is possible to contact the operating company of the other network regarding the distribution of the monitoring signal in the monitoring section of the other network after preventing it from leaking to other companies.

なお、本来の管理対象が自ネットワークＡであるネットワーク管理装置１０にとって、監視指示オーダの始点ＩＤおよび終点ＩＤの両方が他ネットワークに所属する場合は、例外的なケースとし、以後の処理を行わないようにしても良い。また、自社オーダ処理部Ｅにおける機能はネットワーク管理装置１０本来の機能であるから、自社オーダ処理部Ｅ自体、ネットワーク管理装置１０の一部と考えても良く、その場合、自社向けオーダ転送部は必要ない。 For the network management apparatus 10 whose original management target is the own network A, if both the start point ID and end point ID of the monitoring instruction order belong to another network, it is an exceptional case and the subsequent processing is not performed. You may do it. Moreover, since the function in the in-house order processing unit E is an original function of the network management device 10, it may be considered as the in-house order processing unit E itself and a part of the network management device 10. In that case, the in-house order transfer unit is unnecessary.
