Summary
In this episode of Networking Tech with Fexingo, hosts Lucas and Luna dive into Segment Routing (SR-MPLS) – a modern approach to traffic engineering that gives ISPs precise control over how packets traverse their backbone. Lucas explains how SR replaces the complex per-flow state of RSVP-TE with simple segment lists encoded in the packet header, reducing network complexity and enabling faster convergence. He references a case where a major European ISP cut backbone latency by 18% after deploying SR, and Luna asks about the operational trade-offs: control-plane simplification versus the loss of per-flow visibility. The conversation also touches on SRv6 and why the industry isn't rushing to adopt it.
