Lucas and Luna dive into BGP Flowspec, a protocol extension that lets network operators filter traffic at line rate during DDoS attacks. They trace how Flowspec evolved from academic papers to production use at major cloud providers, walk through a real-world mitigation example where a single rule dropped 95% of malicious traffic in under 30 seconds, and discuss why adoption remains patchy despite clear benefits. The hosts also touch on the tension between centralized SDN controllers and distributed router-level enforcement, and how large enterprises are now using Flowspec to protect their own WAN links. By the end, you'll understand why Flowspec is the unsung hero of modern DDoS defense — and why your network team might be missing it.
