How Segment Routing Simplifies Wide Area Networks

Lucas and Luna unpack Segment Routing (SR-MPLS), the technology that lets network operators define explicit paths through a wide area network without maintaining per-flow state on intermediate routers. They walk through the classic problem — traffic engineering on large MPLS networks requires hundreds of label-switched paths and constant signalling — and show how SR replaces that with a single source-routed instruction list carried in the packet header. Along the way they discuss real-world deployment at a Tier 1 European service provider that cut its LSP count by 94 percent, and examine how SRv6 extends the same idea into IPv6 for cloud and 5G backhaul. They also touch on the operational shift: operators move from troubleshooting per-tunnel state to designing segment lists, which changes the skill set required in the NOC.
