ネットワーク図（nwdiag付き）

Network Diagram with nwdiag

ネットワーク図とは、コンピューターや通信ネットワークを視覚的に表したものである。サーバー、ルーター、スイッチ、ハブ、デバイスなどのネットワーク・コンポーネントの配置と相互接続を図解します。ネットワーク・ダイアグラムは、ネットワーク・エンジニアや管理者にとって、ネットワークを理解し、設定し、トラブルシューティングするための貴重なツールです。また、ネットワーク内のデータの構造と流れを視覚化し、最適なパフォーマンスとセキュリティを確保するためにも不可欠です。

nwdiag は、Takeshi Komiya氏によって開発され、ネットワーク図を素早くスケッチするための合理的なプラットフォームを提供します。この革新的なツールを提供してくれたTakeshi氏に感謝します！

その直感的な構文から、nwdiagは PlantUMLにシームレスに統合されています。ここで紹介する例は、Takeshiによって文書化されたものに触発されたものです。

A network diagram is a visual representation of a computer or telecommunications network. It illustrates the arrangement and interconnections of network components, including servers, routers, switches, hubs, and devices. Network diagrams are invaluable tools for network engineers and administrators to understand, set up, and troubleshoot networks. They are also essential for visualizing the structure and flow of data in a network, ensuring optimal performance and security.

nwdiag, developed by Takeshi Komiya, provides a streamlined platform to swiftly sketch network diagrams. We extend our gratitude to Takeshi for this innovative tool!

Given its intuitive syntax, nwdiag has been seamlessly integrated into PlantUML. The examples showcased here are inspired by the ones documented by Takeshi.

  • addresses (separated by comma ,);
  • color;
  • description;
  • shape.

@startuml
nwdiag {
  network Sample_front {
    address = "192.168.10.0/24"
    color = "red"

    // define group
    group web {
      web01 [address = ".1, .2", shape = "node"]
      web02 [address = ".2, .3"]
    }

nwdiag {
  group {
    color = "#CCFFCC";
    description = "Long group description";

    web01;
    web02;
    db01;
  }

  network dmz {
    web01;
    web02;
  }
  network internal {
    web01;
    web02;
    db01 [address = ".101", shape = database];
  }
}
@enduml

[Ref. QA-12056]

スプライトの使用

Using Sprites

標準ライブラリやその他のライブラリに含まれる、あらゆるスプライト（アイコン）を使用できます。

スプライトは<$sprite>の記法を使います。\nで改行できます。また、その他のCreole記法も使用できます。 

@startuml
!include <office/Servers/application_server>
!include <office/Servers/database_server>

nwdiag {
  network dmz {
      address = "210.x.x.x/24"

      // set multiple addresses (using comma)
      web01 [address = "210.x.x.1, 210.x.x.20",  description = "<$application_server>\n web01"]
      web02 [address = "210.x.x.2",  description = "<$application_server>\n web02"];
  }
  network internal {
      address = "172.x.x.x/24";

      web01 [address = "172.x.x.1"];
      web02 [address = "172.x.x.2"];
      db01 [address = "172.x.x.100",  description = "<$database_server>\n db01"];
      db02 [address = "172.x.x.101",  description = "<$database_server>\n db02"];
  }
}
@enduml

[Ref. QA-11862]

You can use all sprites (icons) from the Standard Library or any other library.

Use the notation <$sprite> to use a sprite, \n to make a new line, or any other Creole syntax. 

@startuml
!include <office/Servers/application_server>
!include <office/Servers/database_server>

nwdiag {
  network dmz {
      address = "210.x.x.x/24"

      // set multiple addresses (using comma)
      web01 [address = "210.x.x.1, 210.x.x.20",  description = "<$application_server>\n web01"]
      web02 [address = "210.x.x.2",  description = "<$application_server>\n web02"];
  }
  network internal {
      address = "172.x.x.x/24";

      web01 [address = "172.x.x.1"];
      web02 [address = "172.x.x.2"];
      db01 [address = "172.x.x.100",  description = "<$database_server>\n db01"];
      db02 [address = "172.x.x.101",  description = "<$database_server>\n db02"];
  }
}
@enduml

[Ref. QA-11862]

OpenIconicの使用

Using OpenIconic

ネットワークまたはノードの説明で、OpenIconicのアイコンを使用することもできます。

<&icon>の記法でアイコンを表示します。<&icon*n>でサイズをn倍にします。\nで改行できます： 

@startuml

nwdiag {
  group nightly {
    color = "#FFAAAA";
    description = "<&clock> Restarted nightly <&clock>";
    web02;
    db01;
  }
  network dmz {
      address = "210.x.x.x/24"

      user [description = "<&person*4.5>\n user1"];
      // set multiple addresses (using comma)
      web01 [address = "210.x.x.1, 210.x.x.20",  description = "<&cog*4>\nweb01"]
      web02 [address = "210.x.x.2",  description = "<&cog*4>\nweb02"];

  }
  network internal {
      address = "172.x.x.x/24";

      web01 [address = "172.x.x.1"];
      web02 [address = "172.x.x.2"];
      db01 [address = "172.x.x.100",  description = "<&spreadsheet*4>\n db01"];
      db02 [address = "172.x.x.101",  description = "<&spreadsheet*4>\n db02"];
      ptr  [address = "172.x.x.110",  description = "<&print*4>\n ptr01"];
  }
}
@enduml

You can also use the icons from OpenIconic in network or node descriptions.

Use the notation <&icon> to make an icon, <&icon*n> to multiply the size by a factor n, and \n to make a newline: 

@startuml

nwdiag {
  group nightly {
    color = "#FFAAAA";
    description = "<&clock> Restarted nightly <&clock>";
    web02;
    db01;
  }
  network dmz {
      address = "210.x.x.x/24"

      user [description = "<&person*4.5>\n user1"];
      // set multiple addresses (using comma)
      web01 [address = "210.x.x.1, 210.x.x.20",  description = "<&cog*4>\nweb01"]
      web02 [address = "210.x.x.2",  description = "<&cog*4>\nweb02"];

  }
  network internal {
      address = "172.x.x.x/24";

      web01 [address = "172.x.x.1"];
      web02 [address = "172.x.x.2"];
      db01 [address = "172.x.x.100",  description = "<&spreadsheet*4>\n db01"];
      db02 [address = "172.x.x.101",  description = "<&spreadsheet*4>\n db02"];
      ptr  [address = "172.x.x.110",  description = "<&print*4>\n ptr01"];
  }
}
@enduml

複数のネットワークに一つのノードを定義

Same nodes on more than two networks

異なる二つ以上のネットワークに同一のノードを使用することができます。この場合、nwdiagではネットワークの上をジャンプする線が描画されます。 

@startuml
nwdiag {
  // define group at outside network definitions
  group {
    color = "#7777FF";

    web01;
    web02;
    db01;
  }

  network dmz {
    color = "pink"

    web01;
    web02;
  }

  network internal {
    web01;
    web02;
    db01 [shape = database ];
  }

  network internal2 {
    color = "LightBlue";

    web01;
    web02;
    db01;
  }

}
@enduml

You can use same nodes on different networks (more than two networks); nwdiag use in this case 'jump line' over networks. 

@startuml
nwdiag {
  // define group at outside network definitions
  group {
    color = "#7777FF";

    web01;
    web02;
    db01;
  }

  network dmz {
    color = "pink"

    web01;
    web02;
  }

  network internal {
    web01;
    web02;
    db01 [shape = database ];
  }

  network internal2 {
    color = "LightBlue";

    web01;
    web02;
    db01;
  }

}
@enduml

ピア接続

Peer networks

ピア接続は、二つのノード間を単純につなぐものです。この場合は、横長の「バス線」ネットワークは使用されません。 

@startuml
nwdiag {
  inet [shape = cloud];
  inet -- router;

  network {
    router;
    web01;
    web02;
  }
}
@enduml

Peer networks are simple connections between two nodes, for which we don't use a horizontal "busbar" network 

@startuml
nwdiag {
  inet [shape = cloud];
  inet -- router;

  network {
    router;
    web01;
    web02;
  }
}

ネットワークの幅の変更

Change width of the networks

ネットワークの幅を変更することができます。一部の（もしくはすべての）ネットワークの幅をfull（最大幅）に設定して揃えることができます。

可能な組合せの例を示します：
  • 無し

@startuml
nwdiag {
  network NETWORK_BASE {
   dev_A   [address = "dev_A" ]
   dev_B [address = "dev_B" ]
  }
  network IntNET1 {
   dev_B [address = "dev_B1" ]
   dev_M [address = "dev_M1" ]
  }
  network IntNET2 {
   dev_B [address = "dev_B2" ]
   dev_M [address = "dev_M2" ]
 }
}
@enduml

  • １番目のみ

@startuml
nwdiag {
  network NETWORK_BASE {
   width = full
   dev_A   [address = "dev_A" ]
   dev_B [address = "dev_B" ]
  }
  network IntNET1 {
   dev_B [address = "dev_B1" ]
   dev_M [address = "dev_M1" ]
  }
  network IntNET2 {
   dev_B [address = "dev_B2" ]
   dev_M [address = "dev_M2" ]
 }
}
@enduml

  • １番目と２番目

@startuml
nwdiag {
  network NETWORK_BASE {
   width = full
   dev_A   [address = "dev_A" ]
   dev_B [address = "dev_B" ]
  }
  network IntNET1 {
   width = full
   dev_B [address = "dev_B1" ]
   dev_M [address = "dev_M1" ]
  }
  network IntNET2 {
   dev_B [address = "dev_B2" ]
   dev_M [address = "dev_M2" ]
 }
}
@enduml

  • すべてに最大幅を指定

@startuml
nwdiag {
  network NETWORK_BASE {
   width = full
   dev_A   [address = "dev_A" ]
   dev_B [address = "dev_B" ]
  }
  network IntNET1 {
   width = full
   dev_B [address = "dev_B1" ]
   dev_M [address = "dev_M1" ]
  }
  network IntNET2 {
   width = full
   dev_B [address = "dev_B2" ]
   dev_M [address = "dev_M2" ]
 }
}
@enduml

WARNING
 This translation need to be updated. 
WARNING

You can change the width of the networks, especially in order to have the same full width for only some or all networks.

Here are some examples, with all the possibilities:
  • without

@startuml
nwdiag {
  network NETWORK_BASE {
   dev_A [address = "dev_A" ]
   dev_B [address = "dev_B" ]
  }
  network IntNET1 {
   dev_B [address = "dev_B1" ]
   dev_M [address = "dev_M1" ]
  }
  network IntNET2 {
   dev_B [address = "dev_B2" ]
   dev_M [address = "dev_M2" ]
 }
}
@enduml

  • only the first

@startuml
nwdiag {
  network NETWORK_BASE {
   width = full
   dev_A [address = "dev_A" ]
   dev_B [address = "dev_B" ]
  }
  network IntNET1 {
   dev_B [address = "dev_B1" ]
   dev_M [address = "dev_M1" ]
  }
  network IntNET2 {
   dev_B [address = "dev_B2" ]
   dev_M [address = "dev_M2" ]
 }
}
@enduml

  • the first and the second

@startuml
nwdiag {
  network NETWORK_BASE {
   width = full
   dev_A [address = "dev_A" ]
   dev_B [address = "dev_B" ]
  }
  network IntNET1 {
   width = full
   dev_B [address = "dev_B1" ]
   dev_M [address = "dev_M1" ]
  }
  network IntNET2 {
   dev_B [address = "dev_B2" ]
   dev_M [address = "dev_M2" ]
 }
}
@enduml

  • all the network (with same full width)

@startuml
nwdiag {
  network NETWORK_BASE {
   width = full
   dev_A [address = "dev_A" ]
   dev_B [address = "dev_B" ]
  }
  network IntNET1 {
   width = full
   dev_B [address = "dev_B1" ]
   dev_M [address = "dev_M1" ]
  }
  network IntNET2 {
   width = full
   dev_B [address = "dev_B2" ]
   dev_M [address = "dev_M2" ]
 }

  }
  network LAN2 {
     a [address = "a2"];
     switch;

@startuml
nwdiag {
  network LAN1 {
     a [address = "a1"];
  }
  network LAN2 {
     a [address = "a2"];
     switch [address = "s2"];
  }
  switch -- equip;
  equip [address = "e3"];
  equip -- printer;
  printer [address = "USB"];
}
