The NQA function measures the performance of various protocols running on networks to ensure that administrators can collect various network running indicators.
With the improving requirements regarding the QoS, especially after traditional IP networks bear voice and video services, Service Level Agreements (SLAs) are commonly signed between broadband service providers and their subscribers. To ensure the committed bandwidth stated in the SLA, broadband service providers require statistics on various network parameters, such as delay, jitter, and packet loss ratio and learn about the performance status of the network in time. The NAQ function delivered by the FW fulfills the requirements.
NQA measures the performance of various protocols running on networks to ensure that broadband service providers can collect various network parameters in real time, for example, the measurement of total HTTP latency, TCP latency, file transmission rate, and FTP latency. Through network management based on these parameters, broadband service providers provide users with services of different levels at different costs.
