Diagnosing Ping, Jitter, and Packet Loss in Networks
Introduction
Network performance is measured by latency (ping), jitter, and packet loss. Understanding these metrics helps troubleshoot connectivity issues.
Ping
Represents the time a packet takes from source to destination and back. High ping means noticeable lag.
Jitter
Measures variation in packet arrival times. High jitter causes unstable connections and call/video quality issues.
Packet Loss
Reflects the percentage of data packets that never reach their target, causing service disruptions.
Practical Tips
Use ping, traceroute, or mtr to identify bottlenecks.
Persistent packet loss may indicate hardware faults or overloaded nodes.
Conclusion
Regularly monitoring these metrics helps keep your network stable, responsive, and reliable.
Tip: Small, reversible changes compound into big wins. Keep rollbacks easy.
