Network resilience is no longer just a hardware concern. Start with a design that assumes every site, branch, and home office needs intelligent routing with observability built in.
Adopt SD-WAN platforms that can steer traffic based on application priority. Combine this with QoS profiles that protect collaboration workloads without starving line-of-business applications.
Finally, establish a closed-loop process with carriers. Share telemetry on jitter, latency, and packet loss so that provider obligations are enforced and chronic issues are escalated rapidly.
