The capacity of a connectivity system to maintain acceptable service levels when components fail, links degrade, or conditions change unexpectedly. Resilient architectures use redundancy, failover paths, and graceful degradation to keep operations running when ideal conditions cannot be guaranteed.

Holdover Timing Holdover Timing is the ability of a system to continue providing acceptable timing when its external reference is temporarily unavailable. It maintains timing during reference loss. Operations Horizon Masking Horizon Masking is the obstruction or loss of visibility near the horizon caused by the Earth, terrain, or vessel geometry. It blocks low-angle paths and prevents RF signals from reaching… Concept/Framework Hub And Spoke Hub And Spoke is a topology or operating model in which multiple endpoints connect through a central hub rather than directly to each other. Concept/Framework Hub And Spoke Architecture Hub And Spoke Architecture is a network design in which endpoints connect through a central hub rather than directly to one another. It simplifies interconnection but centralizes dependency. Concept/Framework Hybrid Network Hybrid Network is a network architecture that combines different transport, access, or ownership models within one operational environment.
