During the course of teaching network modules, information technology teachers often face challenges in creating real-world local area networks due to insufficient conditions. Some network simulation software requires payment, so is there an alternative solution? Here, the author has built a platform for simulating the construction of a virtual local area network, which is very simple and can be implemented by almost anyone (the key is that it is provided for free).Here, I provide video examples of single local area network communication and communication between two or more subnetworks for everyone to exchange ideas. If there are better suggestions, please feel free to propose them, and I will continue to improve this in the future. Thank you all for your attention and support.The simulation experiment for a single subnet (local area network) communication is shown below:The simulation experiment for communication between two or more subnets (local area networks) is shown below:To summarize:
This is a virtual local area network simulation system with the following core functions:
Main Features
- Device Management: Supports adding routers, switches, client computers, and servers
- Drag-and-Drop Operation: Devices can be freely dragged to any position
- Network Configuration: Allows setting device names, IP addresses, subnet masks, and default gateways
- Connection Management: Create and delete network connections between devices
- Connectivity Testing: Test the communication path between any two devices
- Packet Visualization: Displays the packet transmission process in an animated form
- Auto Layout: Automatically arranges device positions
- Log Recording: Detailed records of operations and test results
Technical Highlights
- Drawing network connection lines
- Implemented drag-and-drop functionality and detection
- Supports cross-subnet communication testing
- Packet transmission animation effects
- Responsive design, adaptable to different screen sizes
User Instructions
- Click on the device in the left toolbar to add it to the workspace
- Drag devices to adjust their positions
- Click on devices for network configuration
- Use the “Add Connection” feature to establish connections between devices
- Test device connectivity in the communication testing tab
This system can serve as an auxiliary tool for internet teaching, helping learners understand network topology and packet transmission principles.
