How Segment Routing is Simplifying the Internet Backbone

Episode 13 of Networking Tech with Fexingo dives into segment routing (SR-MPLS and SRv6), a technology that's quietly replacing complex MPLS traffic engineering with a simpler, source-routed model. Lucas and Luna unpack how segment routing works, why it reduces network state by up to 90 percent in some cases, and how companies like Google and Microsoft are using it to handle exploding traffic from AI and cloud workloads. They walk through a concrete example: a tier-1 ISP that cut its network operations cost by 40 percent after adopting segment routing. The episode covers the evolution from RSVP-TE to SR-MPLS, the emergence of SRv6 for IPv6-native networks, and the real-world tradeoffs in migration. Perfect for network engineers, infrastructure folks, and anyone curious about how the big pipes actually route packets. #SegmentRouting #SRMPLS #SRv6 #NetworkEngineering #InternetInfrastructure #MPLS #TrafficEngineering #RoutingProtocols #ISP #CloudNetworking #AIdataCenters #IPv6 #Technology #TechPodcast #NetworkArchitecture #Telecom #FexingoBusiness #BusinessPodcast Keep every episode free: buymeacoffee.com/fexingo
