This is a Malicious Data Flow Control System within Software Defined Networks, developed by myself during my bachelor's degree in Feb 2023. In this project, I:
- Designed and implemented a malicious data flow control system using the Floodlight controller framework to enhance security.
- Developed and integrated link flow detection and data flow decision-making modules for real-time threat mitigation.
- Analyzed switch edge port data to monitor traffic patterns, adjusting system states to optimize performance.
- Managed IP address pairs and processed incoming data packets, improving threat detection and response times.
To run this code, you have to install JDK 1.8 on your physical machine. This project use a Mininet platform in a Ubuntu virtual machine to simulate a simple SDN topology, and run a Floodlight Controller on the physical machine to send commands, thus control the traffic in the vm's network.
N.B. This project cannot be used independently. It has to be executed based on Java source code of Floodlight Controller. Due to the limitation of file size, I cannot upload it here.
The topology is as below:
Sadly, I lost the script to set up a virtual network after reinstalling my OS.
