NQA configuration

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 proper actions.

NQA features

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 1 1 test types: ICMP echo, DHCP, DNS, FTP, HTTP, UDP jitter, SNMP, TCP, UDP echo, voice,
and DLSw.
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 threshold monitoring
NQA supports threshold monitoring for performance parameters such as average delay jitter and packet
round-trip time. The performance parameters to be monitored are monitored elements. NQA monitors
threshold violations for a monitored element, and reacts to certain measurement conditions (for example,
sending trap messages to the network management server). This helps network administrators
understand the network service quality and network performance.

Table 1 describes the monitored elements and the NQA test types in which the elements can be
monitored.
