Commonly used tools for drawing topology diagrams include Microsoft Visio, which is integrated with Microsoft's office software. Its advantages are user-friendly interface and easy to use, but it can only be used for static topology diagrams and cannot be used for dynamic networks; Diagrams is an open source software.
