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 Smart NICs Are Offloading Network Processing","slug":"how-smart-nics-are-offloading-network-processing","published_at":"2026-06-23T22:20:25+00:00","page_url":"https://stenobird.com/podcast/networking-tech-with-fexingo-internet-infrastructure-routing-and-network-engineering-7871928/how-smart-nics-are-offloading-network-processing","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-0069.mp3","audio_url":"https://audio.fexingo.com/business/networking-tech/episode-0069.mp3","summary":"Episode 69 of Networking Tech with Fexingo. Lucas and Luna explore how Smart NICs (network interface cards with onboard processors) are offloading packet processing from CPU cores, reducing latency and freeing up server resources for applications. They focus on the rise of NVIDIA's BlueField DPU, the impact on hyperscaler data centers like Microsoft Azure, and how Smart NICs enable software-defined storage and security at line rate. They also discuss the economics: a $500 Smart NIC vs. upgrading entire server fleets. This episode includes specific numbers on performance gains and adoption timelines, plus a look at how startups like Fungible (acquired by Microsoft) shaped the market. Perfect for network engineers, cloud architects, and anyone curious about the hardware making the internet faster. #SmartNIC #DPU #NVIDIA #BlueField #NetworkOffload #DataCenter #MicrosoftAzure #Fungible #PacketProcessing #SoftwareDefinedStorage #NetworkSecurity #RDMA #NVMeOverFabrics #Hyperscaler #CloudComputing #Technology #FexingoBusiness #BusinessPodcast Keep every episode free: buymeacoffee.com/fexingo","meta_description":"Episode 69 of Networking Tech with Fexingo.
