Applicable Environment
Jitter time refers to the interval for receiving two consecutive packets minus the interval for
sending these two packets.
The process of the ICMP jitter test is as follows:
l
l
l
The maximum, minimum, and average jitter time and the maximum unidirectional delay of the
packets from the source to the destination and from the destination to the source are calculated
according to the information received on the source. Based on these data, the network status is
clearly presented.
In the jitter test, you can set the number of packets to be sent consecutively in each test instance.
Through this setting, the actual traffic of a kind of packet during a time period can be simulated.
If the server is a non-Huawei device, you can test the jitter of the network by configuring an
ICMP jitter test instance.
Pre-configuration Tasks
Before configuring an ICMP jitter test, configure a reachable route between the NQA client and
the server.
Data Preparation
To configure a jitter test, you need the following data.

6.18.2 Configuring Parameters for the ICMP Jitter Test

This part describes how to set ICMP jitter test parameters.
Context
Do as follows on the NQA client:
Issue 01 (2011-10-26)
The source sends packets to the destination at a set interval.
After receiving a packet, the destination adds a timestamp to the packet and sends it back
to the source.
After receiving the returned packets, the source obtains the jitter time by subtracting the
interval for sending the packets from the interval for receiving the packets.
Data
Administrator of the NQA test instance and name of the test instance
Destination IP address
(Optional) Name of a VPN instance, source IP address ,number of test probes sent
each time, number of test packets sent each time, interval for sending test packets,
ratio of the failed NQA tests, and version number of jitter packets
Start mode and end mode
