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 Network Observability with eBPF Works","slug":"how-network-observability-with-ebpf-works-2","published_at":"2026-06-22T10:03:08+00:00","page_url":"https://stenobird.com/podcast/networking-tech-with-fexingo-internet-infrastructure-routing-and-network-engineering-7871928/how-network-observability-with-ebpf-works-2","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-0066.mp3","audio_url":"https://audio.fexingo.com/business/networking-tech/episode-0066.mp3","summary":"This episode of Networking Tech with Fexingo dives into eBPF (extended Berkeley Packet Filter), a technology that lets network engineers run sandboxed programs in the Linux kernel without changing kernel code or loading modules. Lucas and Luna explain how eBPF enables deep observability into network traffic, security events, and performance metrics with minimal overhead — used by companies like Netflix, Cilium, and Facebook for real-time packet filtering, load balancing, and troubleshooting. They walk through a concrete example: how a team can trace every TCP retransmission across a Kubernetes cluster without restarting a single pod. The hosts also discuss the shift from legacy monitoring tools like iptables to eBPF-powered solutions, and why this matters for modern cloud-native networks. If you've ever wondered how engineers see inside their network without adding latency, this episode is for you. #eBPF #NetworkObservability #LinuxKernel #ExtendedBerkeleyPacketFilter #Cilium #CloudNative #KubernetesNetworking #PacketFiltering #TCPRetransmission #NetworkPerformance #Technology #Networking #FexingoBusiness #BusinessPodcast #Infrastructure #DevOps #SiteReliabilityEngineering #NetworkTracing Keep every episode free: buymeacoffee.com/fexingo","meta_description":"This episode of Networking Tech with Fexingo dives into eBPF (extended Berkeley Packet Filter), a technology that lets network engineers run sandboxed pro…","key_points":[],"chapters":[],"topics":[],"duration_seconds":550,"processing_state":"not_requested","actions":[{"name":"request_transcript","method":"POST","url":"https://stenobird.com/v1/public/podcasts/networking-tech-with-fexingo-internet-infrastructure-routing-and-network-engineering-7871928/episodes/how-network-observability-with-ebpf-works-2/transcription-requests","description":"Idempotently request low-priority transcript generation for this episode."},{"name":"read_markdown","method":"GET","url":"https://stenobird.com/podcast/networking-tech-with-fexingo-internet-infrastructure-routing-and-network-engineering-7871928/how-network-observability-with-ebpf-works-2.md","description":"Read the agent-friendly Markdown representation of this episode resource."}]}}
