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 Backplane Bandwidth Shapes Modern Switch Design","slug":"how-backplane-bandwidth-shapes-modern-switch-design","published_at":"2026-07-17T10:16:43+00:00","page_url":"https://stenobird.com/podcast/networking-tech-with-fexingo-internet-infrastructure-routing-and-network-engineering-7871928/how-backplane-bandwidth-shapes-modern-switch-design","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-0116.mp3","audio_url":"https://audio.fexingo.com/business/networking-tech/episode-0116.mp3","summary":"Episode 116 of Networking Tech with Fexingo explores the often-overlooked role of backplane bandwidth in modern switch and router design. Lucas and Luna explain how internal fabric capacity dictates real-world throughput, using the example of a typical 100-gigabit-per-second port count versus actual forwarding capacity. They discuss the shift from shared-bus architectures to crossbar and Clos fabrics, and why oversubscription ratios matter more than raw port speeds. The episode also touches on how hyperscalers like Google and Microsoft design custom switches to match their specific traffic patterns, and how the industry is moving toward 51.2-terabit-per-second switch ASICs. A practical anchor: why a 48-port 25-gig switch with 12.8 terabit-per-second backplane can still bottleneck under heavy east-west traffic. #BackplaneBandwidth #SwitchDesign #NetworkEngineering #DataCenterNetworking #ClosFabric #Oversubscription #SwitchASIC #100Gigabit #Hyperscaler #GoogleNetwork #MicrosoftNetwork #EastWestTraffic #NetworkArchitecture #TechPodcast #FexingoBusiness #BusinessPodcast #InternetInfrastructure #RoutingAndSwitching Keep every episode free: buymeacoffee.com/fexingo","meta_description":"Episode 116 of Networking Tech with Fexingo explores the often-overlooked role of backplane bandwidth in modern switch and router design.
