Why is QoS important for telemetry networks across sites?

Why is QoS important for telemetry networks across sites?

• A. To encrypt data end-to-end.
• B. To ensure devices are authenticated.
• C. To prioritize critical telemetry traffic and meet latency bounds.
• D. To replace the need for secure VPNs.

Answer: (C)

Quality of Service focuses on guaranteeing predictable network performance for time-sensitive traffic. In telemetry networks that span multiple sites, data such as alarms, heartbeats, and real-time telemetry must arrive within strict time limits. By classifying telemetry as high-priority and applying appropriate queuing, scheduling, and resource allocation, the network minimizes delays and jitter and keeps latency within defined bounds even when links are congested. This ensures monitoring systems receive timely information and control decisions can be made promptly. Encryption, device authentication, and VPNs address security or secure connectivity, not the guaranteed delivery timing that telemetry often requires.
