Configuring Udp Jitter Tests - H3C S3100V2-52TP Configuration Manual

To do...
Configure the HTTP version used in
HTTP tests
Configure optional parameters
NOTE:
The TCP port must be port 80 on the HTTP server for NQA HTTP tests.

Configuring UDP jitter tests

NOTE:
Do not perform NQA UDP jitter tests on known ports, ports from 1 to 1023. Otherwise, UDP jitter tests
might fail or the corresponding services of this port might be unavailable.
Real-time services such as voice and video have high requirements on delay jitters. UDP jitter tests of an
NQA test group obtain uni/bi-directional delay jitters. The test results help you verify whether a network
can carry real-time services.
A UDP jitter test performs the following procedure:
The source sends packets to the destination port at regular intervals.
1.
The destination affixes a time stamp to each packet that it receives, and then sends the packet back

to the source.
Upon receiving the response, the source calculates the delay jitter, which reflects network

performance. Delay refers to the amount of time it takes a packet to be transmitted from source to
destination or from destination to source. Delay jitter is the delay variation over time.
Configuration prerequisites
UDP jitter tests require cooperation between the NQA server and the NQA client. Before you start UDP
jitter tests, configure UDP listening services on the NQA server. For more information about UDP listening
service configuration, see
Configuring UDP jitter tests
Follow these steps to configure UDP jitter tests:
To do...
Enter system view
Enter NQA test group view
Configure the test type as UDP
jitter, and enter test type view
Use the command...
http-version v1.0
See "Configuring optional
parameters for an NQA
test group"
