6.19 Configuring an ICMP Jitter Test

This section describes how to configure an ICMP jitter test to measure jitter on IP networks.

6.19.1 Establishing the Configuration Task

Before configuring an ICMP 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
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.
The devices at the two ends of the tested link can be both Huawei devices or not.
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.

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
