6.12 Configuring the Jitter Test

This section describes how to configure a jitter test to check jitter on the network. You can
perform a jitter test only when both the client and the server are Huawei devices.

6.12.1 Establishing the Configuration Task

Before configuring a jitter test, familiarize yourself with the applicable environment, complete
the pre-configuration tasks, and obtain the required data. This can help you complete the
configuration task quickly and accurately.
Applicable Environment
The jitter time refers to the interval for sending two adjacent packets minus the interval for
receiving the two packets.
The process of a Jitter test is as follows:
1.
2.
3.
The maximum, minimum, and average jitter time calculated based on the information received
on the source can clearly show the network status.

Run the display nqa results [ test-instance admin-name test-name ] command to view the
test results on the NQA client.
Run the display nqa-server command to view the information about the NQA server.
The test is finished
Send operation times: 3
Completion:success

Disconnect operation number:0
System busy operation number:0
Operation sequence errors number:0
Destination ip address:10.2.1.2
Min/Max/Average Completion Time: 32/109/67
Sum/Square-Sum Completion Time: 203/16749
Last Good Probe Time: 2006-8-5 16:9:21.6
Lost packet ratio: 0 %
The source sends a packet to the destination at a specified interval.
After receiving the packet, the destination adds a timestamp to the packet and returns them
to the source.
After receiving the returned packets, the source subtracts the interval for the source to send
two adjacent packets from the interval for the destination to receive the two packets and
then obtains the jitter time.
