tinyXDP (Under Revision)

2023 - 2024

DDoS mitigation tool using XDP for endpoint protection. An experimental project that implements traffic control at the pre-kernel level using eBPF/XDP.

Currently working on a complete redesign as the initial version revealed areas needing improvement: the implementation doesn't fully comply with RFC networking standards, and I've identified the need for a deeper understanding of network kernel internals. Planning to restart the project after further study of kernel networking and RFC specifications.
