Understanding eBPF and XDP DDoS Protection

May 2025

How eBPF-based packet filtering at the kernel level provides unmatched DDoS mitigation for Minecraft servers.

eBPF (extended Berkeley Packet Filter) combined with XDP (eXpress Data Path) allows us to filter malicious traffic at the kernel level before it reaches userspace. This helps protect Minecraft servers during volumetric and protocol abuse attacks. XDP filters inspect incoming packets in real-time, dropping invalid or hostile traffic early. Combined with diverse upstream capacity, this reduces attack impact while keeping latency stable for legitimate players.
