This project represents our study project I and is a desktop application with which two devices can be connected and communicate with each other via the network. The focus will be on reader-writer problems and the resulting delays when sending/receiving packets via a TCP connection.
- Network Connection of two devices
- Automatic detection of the other device on local network
- Automatic connection trying to connect to the other device
- Sending and receiving of packets automatically
- Sending of packets with different delays
- Fast (0ms)
- Dynamic (random between 0 and 1000ms)
- Slow (1000ms)
- Visualization of received packets
- Connection status LED
- Dark mode
- Fullscreen mode
- Cross-platform
If you want to build the project yourself, install the following dependencies:
sudo apt install libvulkan-dev libxkbcommon-x11-dev libx11-xcb-dev libegl1-mesa-dev libwayland-dev libx11-dev libxcursor-dev libxfixes-dev pkg-config libxcursor-dev libxinerama-dev libxrandr-dev libxi-dev libgl-devDownload the executable for your operating system of choice! After successfully downloading it just execute it on two devices and have fun!
The backend expects to receive raw TCP packets. It does not use a protocol like HTTP or MQTT. Instead, the payload of each TCP packet is parsed as a string and processed accordingly.
You can manually send TCP packets to the backend using a tool like nc (Netcat). For example:
echo -n "fast" | nc 127.0.0.1 56867
echo -n "dynamic" | nc 127.0.0.1 56867
echo -n "slow" | nc 127.0.0.1 56867
