Path diversity, spare capacity, power continuity and restoration planning.
Systems note: infrastructure classifications, standards and responsibilities vary by country and operator. Use current local requirements for real decisions.
Why this matters
Path diversity, spare capacity, power continuity and restoration planning.
Core system ideas
Network redundancy should consider physical route diversity as well as logical configuration.
Congestion can degrade service even when infrastructure has not fully failed.
Restoration depends on field access, spare equipment, power and provider coordination.
What to review
Useful reviews usually combine service criticality, dependencies, condition, capacity, maintenance, alternate arrangements, restoration time and clear ownership rather than relying on one isolated metric.
