NQA Overview

Network Quality Analyzer (NQA) can perform various types of tests and collect network performance

and service quality parameters such as delay jitter, time for establishing a TCP connection, time for

establishing an FTP connection, and file transfer rate.

With the NQA test results, you can diagnose and locate network faults, know network performance in

time and take corresponding measures.

Benefits 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. As an enhancement to Ping, NQA provides more test types and

functions.

NQA supports ten test types: ICMP echo, DHCP, DNS, FTP, HTTP, UDP jitter, SNMP, TCP, UDP echo,

and voice.

NQA enables the client to send probe packets of different test types to detect the protocol availability

and response time of the peer. The test result helps you understand network performance.

Supporting the collaboration function

Collaboration is implemented by establishing reaction entries to monitor the detection results of NQA

probes. If the number of consecutive probe failures reaches a certain limit, NQA informs the track
