## Resource

Episode 72 of Networking Tech with Fexingo explores how low-earth-orbit satellite constellations like Starlink are forcing fundamental changes in Internet routing. With satellites moving at 7.5 km/s and handing off connections every few minutes, traditional BGP and TCP protocols break down. Lucas and Luna dive into the specific engineering challenges: laser crosslinks that create a mesh in orbit, the need for predictive routing algorithms, and how satellite gateways peer with terrestrial IXPs. They discuss the IETF's work on ‘delay-tolerant networking’ and how SpaceX's network now carries over 100 Gbps per satellite laser link. A concrete look at how the physical layer is rewriting routing tables from the sky down. #SatelliteInternet #Starlink #Routing #BGP #LEOConstellation #NetworkEngineering #InternetInfrastructure #LaserCrosslinks #DelayTolerantNetworking #TCP #IETF #SpaceX #Technology #Podcast #FexingoBusiness #BusinessPodcast #NetworkingTech #OrbitRouting Keep every episode free: buymeacoffee.com/fexingo
