KOREN 6.0: Korea rebuilds its national research network as an AI-first, autonomous backbone

The Korea Research Network 6.0 upgrade retires the "gigabit + quantum test" era. It targets 1.6 Tbps backbones, agentic autonomous operations and dedicated AI data-center segments - construction from 2028, completion 2031.

The fact

MSIT and the National Information Society Agency (NIA) have unveiled the strategy for KOREN 6.0, the next-generation Korea Research Network. The upgrade lifts backbone and AI-datacenter internal networks to 1.6 Tbps, regional networks to 400 Gbps, and subscriber networks to 100 Gbps. Strategy work completes in 2026, construction starts 2028, target completion 2031 - an approximately ₩50 billion program over four years per ETNews. The stated design intent is "TM Forum Level-5" autonomous network operations built on agentic AI, and a clean split between the research network (universities, AI startups) and the test network (equipment, optics).

Our read

Two shifts stand out. First, KOREN 6.0 stops treating the AI data center as a customer and starts treating it as an internal segment of the research fabric - the AI-DC LAN is inside the backbone plan, not bolted on. Second, "Level-5 autonomous" is a bet that the network layer itself is the next AI application: closed-loop control agents doing what NOC engineers do today. That's a very concrete industrial thesis, not a research paper.

What to watch

Whether the 1.6 Tbps figure survives contact with optical vendor lead times - the industry is short on 800G ZR+ transceivers, let alone 1.6T. And whether the AIDC Alliance (publication #1719) uses KOREN 6.0 as its physical layer, which would tie the demand/supply/foundation policy to a specific fiber footprint.
