This section describes NQA background and NQA functions.

As value-added services develop, users and carriers demand higher quality of service (QoS). After voice over IP and video over IP services are carried out, carriers and users reach service level agreements (SLAs) to implement QoS guaranteed services.

To provide committed bandwidth for users, carriers configure devices to collect statistics on delay time, jitter time, and the packet loss ratio. The information helps them analyze network performance.

The NE40E provides NQA to meet the preceding requirements.

NQA measures the performance of each protocol running on a network and helps carriers collect network operation indicators, such as the delay time of a TCP connection, packet loss ratio, and path maximum transmission unit (MTU). Carriers provide users with differentiated services and charge users differently based on these indicators. NQA is also an effective tool to diagnose and locate faults in a network.
