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 Segment Routing Is Transforming ISP Traffic Engineering","slug":"how-segment-routing-is-transforming-isp-traffic-engineering","published_at":"2026-07-12T22:47:46+00:00","page_url":"https://stenobird.com/podcast/networking-tech-with-fexingo-internet-infrastructure-routing-and-network-engineering-7871928/how-segment-routing-is-transforming-isp-traffic-engineering","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-0107.mp3","audio_url":"https://audio.fexingo.com/business/networking-tech/episode-0107.mp3","summary":"In this episode of Networking Tech with Fexingo, hosts Lucas and Luna dive into Segment Routing (SR-MPLS) – a modern approach to traffic engineering that gives ISPs precise control over how packets traverse their backbone. Lucas explains how SR replaces the complex per-flow state of RSVP-TE with simple segment lists encoded in the packet header, reducing network complexity and enabling faster convergence. He references a case where a major European ISP cut backbone latency by 18% after deploying SR, and Luna asks about the operational trade-offs: control-plane simplification versus the loss of per-flow visibility. The conversation also touches on SRv6 and why the industry isn't rushing to adopt it.
