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 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.
Supporting multiple test types
Ping can use only the Internet Control Message Protocol (ICMP) to test the
reachability of the destination host and the roundtrip time of a packet to the
destination. NQA is an enhanced Ping tool used for testing the performance of
protocols running on networks.
At present, NQA supports nine test types: ICMP-echo, DHCP, 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.
