Plain-language definition
Designing so a single failure does not stop service.
Technical definition
HA uses redundant nodes, persistent state, redundant links and automatic failover; Guardivia platforms use active-active or active-standby pairs, VRRP and geo-redundancy where supported.
Why it matters
Messaging and signaling are real-time; HA is mandatory for carrier-grade service.
