Configuring NQA

This chapter provides an overview of NQA configuration.

Overview

Network quality analyzer (NQA) allows you to monitor link status, measure network performance,
verify the service levels for IP services and applications, and troubleshoot network problems. NQA
provides the following types of operations.
•
ICMP echo
•
DHCP
•
DNS
•
FTP
•
HTTP
•
UDP jitter
•
SNMP
•
TCP
•
UDP echo
•
Voice
•
Data Link Switching (DLSw)
As shown in
device by simulating IP services and applications to measure network performance. The obtained
performance metrics include the one-way latency, jitter, packet loss, voice quality, application
performance, and server response time.
All the types of NQA operations require the NQA client, but only the TCP, UDP echo, UDP jitter, and
voice operations require the NQA server. The NQA operations for services that are already provided
by the destination device such as FTP do not need the NQA server.
You can configure the NQA server to listen and respond on specific ports to satisfy various test
needs.

Collaboration

NQA can collaborate with the Track module to notify application modules of state or performance
changes so that the application modules can take predefined actions. For more information about
collaboration, see High Availability Configuration Guide.
