Configuring the UDP jitter operation

CAUTION:
To ensure successful UDP jitter operations and avoid affecting existing services, do not perform the
operations on well-known ports from 1 to 1023.
Jitter means inter-packet delay variance. A UDP jitter operation measures unidirectional and
bidirectional jitters so that you can verify whether the network can carry jitter-sensitive services such as
real-time voice and video services.
The UDP jitter operation works as follows:
1. The NQA client sends UDP packets to the destination port at a regular interval.
2. The destination device takes a time stamp to each packet that it receives, and then sends the
packet back to the NQA client.
3. Upon receiving the responses, the NQA client calculates the jitter according to the time stamps.
The UDP jitter operation requires both the NQA server and the NQA client. Before you perform the UDP
jitter operation, configure the UDP listening service on the NQA server. For more information about UDP
listening service configuration, see
To configure a UDP jitter operation:
Step
1. Enter system view.
2. Create an NQA operation
and enter NQA operation
view.
3. Specify the UDP jitter type
and enter its view.
4. Specify the destination
address of UDP packets.

Remarks
N/A
By default, no NQA operation is
created.

The destination IP address must be
the same as that of the listening
service on the NQA server.
