How does Link 16 support resilience against node failure?

• A. Rely on a single, hardened main node with rapid data fusion.
• B. Deploy disjoint networks that do not share data.
• C. By enabling redundancy, multi-node operation, and alternative paths to maintain net integrity.
• D. By compressing data to reduce transmission load.

Answer: (C)

Resilience against node failure comes from redundancy and multiple pathways. In Link 16, the network is built with several nodes that can all participate in relaying and distributing data. If one node goes down, others continue to forward messages and data can be routed through alternative paths, so the overall network stays connected and maintains situational awareness. This multi-node operation and availability of alternative routes prevent a single point of failure from crippling the net. Relying on a single hardened main node creates a vulnerable single point of failure. Deploying disjoint networks that don’t share data defeats the goal of a unified picture, and simply compressing data reduces overhead but doesn’t improve the network’s ability to survive node losses.
