Episode 74 of Networking Tech with Fexingo dives into a question network engineers are wrestling with in mid-2026: as low-Earth-orbit satellite constellations from Starlink, OneWeb, and Kuiper grow to tens of thousands of satellites, how does internet routing adapt? Lucas and Luna break down the specific challenge of inter-satellite laser links — currently around 9,000 active links in orbit — and how they create a mesh network that moves traffic at the speed of light in vacuum, roughly 50 percent faster than in fiber. They explore how the old BGP routing protocol struggles with a topology that changes every 90 minutes as satellites orbit, and how new approaches like delay-tolerant networking and predictive routing tables are being tested. Specific numbers include: 6,000 Starlink satellites as of June 2026, with laser crosslinks carrying about 42 percent of their backbone traffic. A concrete look at how the internet's physical layer is leaving the ground. #SpaceInternet #LEOConstellations #SatelliteRouting #Starlink #OneWeb #Kuiper #LaserLinks #InterSatelliteLinks #BGP #DelayTolerantNetworking #NetworkTopology #InternetInfrastructure #RoutingProtocols #NetworkEngineering #Technology #FexingoBusiness #BusinessPodcast #NetworkingTech Keep every episode free: buymeacoffee.com/fexingo
