What it is
WAN redundancy uses an independent secondary path—ideally with a different carrier, route or access medium—to reduce single points of failure.
Connectivity · Technical Overview
WAN Link Redundancy
Secondary connectivity engineered to keep a site online when the primary WAN circuit becomes unavailable or degraded.
← Back to solutionsWhy it matters
A backup circuit only creates resilience when failover behavior, routing, capacity and operational procedures are designed and tested.
NARDIN delivery scope
We identify failure domains, select an independent backup medium, configure routing or SD-WAN failover, define health checks and perform controlled failover/failback testing.
Customer deliverables
A tested primary/secondary connectivity design with documented failover logic and known service limitations.
Typical use cases
Business-critical offices, payment environments, contact centers, remote facilities and any site where WAN downtime stops operations.
Delivery lifecycle
01Requirements discovery and current-state assessment.
02Architecture, dependencies and implementation planning.
03Technical specification, configuration baseline and delivery preparation.
04Implementation, integration, testing and controlled commissioning.
05As-built documentation, operational handover and managed support where required.
