MPLS

Alcatel Submarine Networks (ASN) has declared force majeure on the Persian Gulf segment of Meta’s 2Africa Pearls extension, indefinitely halting work on one of the most critical subsea cable projects connecting the Middle East to global internet infrastructure. The cable-laying vessel Ile De Batz sits stranded off Dammam, Saudi Arabia, unable to complete connections to onshore landing stations — and this is just the beginning of what SP engineers need to worry about. ...

CCIE Service Provider is not a dead track — it’s an undervalued one. Fewer candidates sitting the exam means less competition for high-paying SP roles, while 5G backhaul deployment, Segment Routing adoption, and the stubborn persistence of MPLS in every major network keep demand strong. According to Stratistics MRC, the global 5G network infrastructure market is projected to reach $122.37 billion by 2034 at a 26.9% CAGR — and every one of those networks needs transport engineers who understand the protocols that CCIE SP tests. ...

CCIE Service Provider holders earn a median salary of $157,000 in 2026, with top earners in major metros clearing $200,000 or more. According to ZipRecruiter (March 2026), the national salary range for CCIE-certified professionals spans $135,000 to $250,000, and SP track holders with segment routing expertise command a clear premium as 5G backhaul demand surges. Key Takeaway: Despite the “SP is dying” narrative, the job market tells a different story — 483 CCIE SP jobs on LinkedIn, 60+ segment routing roles on ZipRecruiter, and median pay that’s competitive with every other CCIE track. ...

Segment Routing Traffic Engineering (SR-TE) replaces RSVP-TE’s hop-by-hop signaling with a source-routed model where the headend router encodes the entire path as a SID list — eliminating per-LSP state from every transit router in your SP backbone. For CCIE SP candidates, understanding both technologies and their tradeoffs is now essential: the v6 lab tests SR-TE policies, TI-LFA, and Flex-Algo alongside legacy RSVP-TE tunnels. Key Takeaway: SR-TE is rapidly replacing RSVP-TE in production SP networks because it eliminates control-plane state from the core, scales better, and integrates natively with SDN controllers — but RSVP-TE’s built-in bandwidth reservation still matters for specific use cases, and both appear on the CCIE SP lab. ...
