NQA Overview

NQA Overview


The Network Quality Analysis (NQA) technology measures network performance and collects statistics on the delay, jitter, and packet loss ratio. NQA monitors network quality of service (QoS) in real time and locates and diagnoses network faults.


To visualize the quality of network services and allow users to check whether the quality of network services meets requirements, the following measures must be taken:

  • Collect data on network devices to describe the quality of network services.

  • Deploy probe devices to monitor the quality of network services.

The preceding measures require devices to provide statistical parameters such as the delay, jitter, and packet loss ratio and require dedicated probe devices. These requirements increase investments on devices.

NQA can precisely test the network operating status and output statistics without using dedicated probe devices, effectively saving costs.
