Each episode opens with a recent network outage, a peering dispute, or a routing-table anomaly — then traces the engineering decisions and business incentives behind it. Lucas maps the technical architecture (BGP, MPLS, IXPs), while Luna pushes on the economics: who pays for undersea cables, why ISPs throttle certain traffic, and how network neutrality shapes startup access. They analyze real incidents — AWS’s Tokyo region failure, a Level 3 vs. Cogent peering war, or the latency impact of a new data-center route — and explain what network engineers actually debate in NANOG meetings. This is not a ‘how the internet works’ primer; it’s the layer-3 view for professionals who manage, build, or invest in network infrastructure. Expect granular discussions of dark fiber, CDN caching strategies, and the politics of IP address allocation. By the end, you’ll see the internet as a finite, fragile, and fiercely competitive topology — and understand why a single undersea cable cut can reset stock prices. #InternetInfrastructure #NetworkEngineering…","last_synced_at":"2026-07-18T22:19:10.157593+00:00","page_url":"https://stenobird.com/podcast/networking-tech-with-fexingo-internet-infrastructure-routing-and-network-engineering-7871928"},"episode":{"title":"How BGP Flowspec Mitigates DDoS Attacks at Router Speed","slug":"how-bgp-flowspec-mitigates-ddos-attacks-at-router-speed","published_at":"2026-06-28T22:26:59+00:00","page_url":"https://stenobird.com/podcast/networking-tech-with-fexingo-internet-infrastructure-routing-and-network-engineering-7871928/how-bgp-flowspec-mitigates-ddos-attacks-at-router-speed","show_page_url":"https://stenobird.com/podcast/networking-tech-with-fexingo-internet-infrastructure-routing-and-network-engineering-7871928","url":"https://audio.fexingo.com/business/networking-tech/episode-0079.mp3","audio_url":"https://audio.fexingo.com/business/networking-tech/episode-0079.mp3","summary":"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. #BGPFlowspec #DDoSMitigation #NetworkSecurity #InternetInfrastructure #BGP #Cisco #Juniper #Cloudflare #NetOps #RouterConfiguration #NetworkEngineering #PacketFiltering #BorderGatewayProtocol #Technology #FexingoBusiness #Fexingo #BusinessPodcast #NetworkProtocols Keep every episode free: buymeacoffee.com/fexingo","meta_description":"Lucas and Luna dive into BGP Flowspec, a protocol extension that lets network operators filter traffic at line rate during DDoS attacks.
