1.前言

本篇目的：Plantuml之nwdiag网络图语法介绍

2.nwdiag网络图语法介绍

网络图是计算机或电信网络的直观表示。它说明了网络组件（包括服务器、路由器、交换机、集线器和设备）的排列和互连。网络图是网络工程师和管理员了解、设置和排除网络故障的宝贵工具。
nwdiag 由Takeshi Komiya 开发，为快速绘制网络图提供了一个精简的平台。我们对 Takeshi 开发的这一创新工具表示感谢！
由于其直观的语法，nwdiag已无缝集成到PlantUML 中。这里展示的示例受到了Takeshi 所记录示例的启发。

3.简单图示

<1>.定义一个网络

@startuml
nwdiag {
  network dmz {
      address = "210.x.x.x/24"
  }
}
@enduml

<2>.定义网络中的一些元素或服务器

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

      web01 [address = "210.x.x.1"];
      web02 [address = "210.x.x.2"];
  }
}
@enduml

<3>.完整的例子

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

      web01 [address = "210.x.x.1"];
      web02 [address = "210.x.x.2"];
  }
  network internal {
      address = "172.x.x.x/24";

      web01 [address = "172.x.x.1"];
      web02 [address = "172.x.x.2"];
      db01;
      db02;
  }
}
@enduml

4.定义多个地址

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

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

      web01 [address = "172.x.x.1"];
      web02 [address = "172.x.x.2"];
      db01;
      db02;
  }
}
@enduml

5.群节点

<1>.在网络定义中定义组

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

    // define group
    group web {
      web01 [address = ".1"];
      web02 [address = ".2"];
    }
  }
  network Sample_back {
    address = "192.168.20.0/24";
    web01 [address = ".1"];
    web02 [address = ".2"];
    db01 [address = ".101"];
    db02 [address = ".102"];

    // define network using defined nodes
    group db {
      db01;
      db02;
    }
  }
}
@enduml

<2>.在网络定义之外定义组

@startuml
nwdiag {
  // define group outside of network definitions
  group {
    color = "#FFAAAA";

    web01;
    web02;
    db01;
  }

  network dmz {
    web01;
    web02;
  }
  network internal {
    web01;
    web02;
    db01;
    db02;
  }
}
@enduml

<3>.一个定义了两个组的例子

@startuml
nwdiag {
  group {
    color = "#FFaaaa";
    web01;
    db01;
  }
  group {
    color = "#aaaaFF";
    web02;
    db02;
  }
  network dmz {
      address = "210.x.x.x/24"

      web01 [address = "210.x.x.1"];
      web02 [address = "210.x.x.2"];
  }
  network internal {
      address = "172.x.x.x/24";

      web01 [address = "172.x.x.1"];
      web02 [address = "172.x.x.2"];
      db01 ;
      db02 ;
  }
}
@enduml

<4>.定义了三个组的例子

@startuml
nwdiag {
  group {
    color = "#FFaaaa";
    web01;
    db01;
  }
  group {
    color = "#aaFFaa";
    web02;
    db02;
  }
  group {
    color = "#aaaaFF";
    web03;
    db03;
  }

  network dmz {
      web01;
      web02;
      web03;
  }
  network internal {
      web01;
      db01 ;
      web02;
      db02 ;
      web03;
      db03;
  }
}
@enduml

6.拓展语法 (适用于组或者网络)

<1>.网络

• 用于网络或者网络的组成部分，你可以添加或者修改:
• 地址 (使用,来分隔);
• 颜色;
• 描述;
• 形状.

@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"]
    }
  }
  network Sample_back {
    address = "192.168.20.0/24"
    color = "palegreen"
    web01 [address = ".1"]
    web02 [address = ".2"]
    db01 [address = ".101", shape = database ]
    db02 [address = ".102"]

    // define network using defined nodes
    group db {
      db01;
      db02;
    }
  }
}
@enduml

<2>.组

• 对于组，你可以添加或修改:
• 颜色;
• 描述.

@startuml
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

7.对等网络

• 对等网络是两个节点之间的简单连接，我们不使用水平“母线”网络

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

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

8.对等网络和组

<1>.第一组

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

    network proxy {
        router;
        app;
    }
    network default {
    	app;
        db;
    }
}
@enduml

<2>.第二组

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

    group {
      color = "pink";
      app;
      db;
    }

    network proxy {
        router;
        app;
    }

    network default {
    	app;
        db;
    }
}
@enduml

<3>.第三组

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

    network proxy {
        router;
        app;
    }

    group {
      color = "pink";
      app;
      db;
    }

    network default {
    	app;
        db;
    }
}
@enduml

<4>.第四组

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

    network proxy {
        router;
        app;
    }
    network default {
    	app;
        db;
    }
    group {
      color = "pink";
      app;
      db;
    }
}
