Have you ever wondered what happens behind the scenes every time you load a webpage? In this episode of Technically U, we dive deep into the invisible infrastructure that powers the modern internet, exploring the routing protocols that quietly and efficiently direct trillions of data packets across the globe.From IS-IS, a protocol born from DECnet and adapted to modern internet routing… to OSPF, the IP-native workhorse of enterprise networks… and MPLS, the “express lane” of digital traffic — we unpack how these technologies work together to create resilient, high-speed networks that few people ever notice, but everyone relies on.You’ll learn:The origin stories and differences between IS-IS and OSPFHow Dijkstra’s algorithm helps routers recalculate paths in real-timeThe truth about MPLS and why it’s not inherently secureHow SD-WAN bridges traditional and modern networkingIf you're curious about how the digital world really works, this episode is your backstage pass to the protocols powering everything online.🔔 Subscribe now to stay in the loop on more eye-opening tech episodes!
