Quality of Experience (QoE)

Quality of Experience (QoE) ###########################

Monitoring communications quality is necessary to detect performance issues and understand if the overall quality matches with the user expectations.

Quality of Experience (QoE) measures how satisfied users are with a network service based on their subjective perception. Unlike Quality of Service (QoS), which focuses on technical metrics (e.g., latency, jitter, packet loss), QoE evaluates the actual end-user experience—such as video streaming smoothness, call clarity, or web browsing responsiveness. QoE is important from various points of view including:

• User Satisfaction: Even if network metrics appear good, poor QoE leads to frustration (e.g., buffering videos or choppy VoIP calls).
• Business Impact: Bad QoE can result in lost customers, reduced productivity, or negative reviews.
• Proactive Troubleshooting: Identifying QoE issues early helps prevent major service disruptions.

.. note::

QoE is available only from Enterprise L license, whereas less capable versions include only basic traffic indicators (e.g. TCP retransmissions) instead of a comprehensive QoE value.
