What steps would you take to troubleshoot and resolve a network latency issue?

Steps to Troubleshoot and Resolve Network Latency Issue

1. Begin by gathering data such as network diagrams, traffic patterns, and recent changes.
2. Use network monitoring tools to identify the source of the latency, such as high traffic volume or packet loss.
3. Check for any network misconfigurations or bottlenecks that could be causing the latency.
4. Analyse the latency issue by testing connectivity and response times between different network components.
5. Implement Quality of Service (QoS) policies to prioritize critical network traffic and reduce latency for important applications.
6. Consider upgrading network hardware or increasing bandwidth if necessary to improve network performance.
7. Document all findings, solutions, and changes made to resolve the network latency issue for future reference.

By following these steps, a NOC engineer can effectively troubleshoot and resolve network latency issues to improve network performance and user experience.
