NQA Overview

Introduction to NQA

Network Quality Analyzer (NQA) analyzes network performance, services and service quality through
sending test packets, and provides you with network performance and service quality parameters
such as delay jitter, TCP connection delay, FTP connection delay and file transfer rate.
With the NQA test results, you can:
1) Know network performance in time and then take corresponding measures.
2) Diagnose and locate network faults.

Features of NQA

Supporting multiple test types
Ping can use only the Internet Control Message Protocol (ICMP) to test the reachability of the
destination host and the round-trip time of a packet to the destination. As an enhancement to the Ping
tool, NQA provides multiple test types and more functions.
At present, NQA supports ten test types: ICMP echo, DHCP, DNS, FTP, HTTP, UDP jitter, SNMP, TCP,
UDP echo and DLSw.
In an NQA test, the client sends different types of test packets to the peer to detect the availability and
the response time of the peer, helping you know protocol availability and network performance based
on the test results.
