Overview of NQA

Overview of NQA


Network Quality Analysis (NQA) measures network performance and collects statistics on 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.

To carry out the preceding measures, devices must provide statistical parameters such as delay, jitter, and packet loss ratio. This requires dedicated probe devices, which increases operation costs.

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