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。
