Threading the Ocean: Mapping Digital Routes Across Submarine Cables using Calypso#

Caleb Wang et al. (Northwestern, U. Oregon)

Why: Submarine cables are the physical WAN backbone with real security/economic exposure; mapping traffic to cables is genuine DC/WAN-interconnect infrastructure work.

What: A framework mapping traceroutes to the submarine cables they traverse, plus "Route Stress," a metric estimating cable criticality.

How: Infers traceroute-to-cable mappings despite industry opacity and validates with case studies on SCN vulnerability.

Where applicable: Global connectivity/resilience analysis; research framework.
