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 Simplifies Wide Area Networks","slug":"how-segment-routing-simplifies-wide-area-networks","published_at":"2026-06-16T21:36:19+00:00","page_url":"https://stenobird.com/podcast/networking-tech-with-fexingo-internet-infrastructure-routing-and-network-engineering-7871928/how-segment-routing-simplifies-wide-area-networks","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-0055.mp3","audio_url":"https://audio.fexingo.com/business/networking-tech/episode-0055.mp3","summary":"Lucas and Luna unpack Segment Routing (SR-MPLS), the technology that lets network operators define explicit paths through a wide area network without maintaining per-flow state on intermediate routers. They walk through the classic problem — traffic engineering on large MPLS networks requires hundreds of label-switched paths and constant signalling — and show how SR replaces that with a single source-routed instruction list carried in the packet header. Along the way they discuss real-world deployment at a Tier 1 European service provider that cut its LSP count by 94 percent, and examine how SRv6 extends the same idea into IPv6 for cloud and 5G backhaul. They also touch on the operational shift: operators move from troubleshooting per-tunnel state to designing segment lists, which changes the skill set required in the NOC.
