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 RDMA Is Reshaping Data Center Network Performance","slug":"how-rdma-is-reshaping-data-center-network-performance","published_at":"2026-07-08T12:14:10+00:00","page_url":"https://stenobird.com/podcast/networking-tech-with-fexingo-internet-infrastructure-routing-and-network-engineering-7871928/how-rdma-is-reshaping-data-center-network-performance","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-0098.mp3","audio_url":"https://audio.fexingo.com/business/networking-tech/episode-0098.mp3","summary":"In this episode of Networking Tech with Fexingo, Lucas and Luna explore how Remote Direct Memory Access (RDMA) is transforming data center networking by allowing servers to exchange data directly without CPU intervention. They break down how RDMA bypasses traditional kernel overhead, reducing latency to single-digit microseconds and cutting CPU load by over 90 percent. Using examples from hyperscale cloud providers and high-frequency trading networks, they explain why RDMA over Converged Ethernet (RoCE) is gaining traction, despite its reliance on lossless network fabrics. They also discuss the challenges of deploying RDMA at scale, including flow control, congestion management, and the need for precise PTP timing. If you work with high-performance computing, storage clusters, or latency-sensitive applications, this episode delivers actionable insight into a technology that is quietly reshaping the backbone of modern data centers. #RDMA #RemoteDirectMemoryAccess #DataCenterNetworking #RoCE #RDMAOverConvergedEthernet #InfiniBand #LowLatencyNetworking #HighPerformanceComputing #StorageNetworking #NVMeOverFabrics #LosslessEthernet #PriorityFlowControl #ExplicitCongestionNotification #PTP #PrecisionTimeProtocol #NetworkEngineering #Technology #FexingoBusiness Keep every episode free: buymeacoffee.com/fexingo","meta_description":"In this episode of Networking Tech with Fexingo, Lucas and Luna explore how Remote Direct Memory Access (RDMA) is transforming data center networking by a…","key_points":[],"chapters":[],"topics":[],"duration_seconds":636,"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-rdma-is-reshaping-data-center-network-performance/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-rdma-is-reshaping-data-center-network-performance.md","description":"Read the agent-friendly Markdown representation of this episode resource."}]}}
