Network Performance Monitoring and Optimization
- Deploy end-to-end monitoring using synthetic probes and real user monitoring (RUM) to detect degradation.
- Establish baselines for latency, jitter, packet loss, and throughput across critical applications.
- Correlate network telemetry with application performance data to isolate root cause.
- Configure NetFlow, sFlow, or IPFIX collection for traffic analysis and capacity planning.
- Use packet capture strategically to diagnose intermittent issues without violating privacy policies.
- Optimize QoS policies to prioritize business-critical applications over best-effort traffic.
- Identify performance bottlenecks at Layer 2 vs. Layer 3 and coordinate with infrastructure teams.
- Balance monitoring granularity with storage, processing, and compliance constraints.
Network Automation and Configuration Management
- Develop idempotent configuration templates using infrastructure-as-code (IaC) tools (e.g., Ansible, Terraform).
