Configure the operation type 

operation { get | post } 

Optional 

By default, the operation type 
for the HTTP is get, that is, 
obtaining data from the HTTP 
server. 

Configure the website that an 
HTTP test visits

Required 

Configure the HTTP version 
used in the HTTP test 

http-version v1.0 

Optional 

By default, HTTP 1.0 is used in 
an HTTP test. 

Configure common optional

Optional 

 

The TCP port number for the HTTP server must be 80 in an HTTP test. Otherwise, the test will fail. 

 

 

It is recommended not to perform an NQA UDP jitter test on known ports, namely, ports from 1 to 1023. 

Otherwise, the NQA test will fail or the corresponding services of this port will be unavailable. 

 

Real-time services such as voice and video have high requirements on delay jitters. With the UDP jitter 

test, uni/bi-directional delay jitters can be obtained to judge whether a network can carry real-time 

services. 

Delay jitter refers to the difference between the interval of receiving two packets consecutively and the 

interval of sending these two packets. The procedure of a UDP jitter test is as follows: 

z 

The source sends packets at regular intervals to the destination port. 

z 

The destination affixes a time stamp to each packet that it receives and then sends it back to the 

source. 

z 

Upon receiving the packet, the source calculates the delay jitter, and the network status can be 

analyzed. 

Configuration prerequisites 

A UDP jitter test requires cooperation between the NQA server and the NQA client. Before the UDP jitter 

test, make sure that the UDP listening function is configured on the NQA server. For the configuration of 

the UDP listening function, refer to
