1.1.1 Introduction to NQA
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
(network quality analyzer) is an enhanced Ping tool used for testing the performance of
protocols running on networks. Besides the Ping functions, NQA can provide the
following functions:
z
Detecting the availability and the response time of DHCP, FTP, HTTP, and SNMP
services.
z
Testing the delay jitter of the network.
z
Verifying the availability of TCP, UDP, and DLSw packets.
Different from Ping, NQA does not display the roundtrip time or time-out time of each
packet on the console terminal in a realtime way. In this case, you have to execute the
display nqa results
command to view NQA test results. In addition, NQA can help you
to set parameters for various tests and start these tests through the network
management system (NMS).
Note:
For the detailed description on TCP, UDP, Jitter, ICMP, HTTP, FTP, DHCP, DLSw and
SNMP, refer to the corresponding manuals.
