Chapter 6 Data Testing
Speed Check testing (optional)
The Speed Check test is used to check downstream and upstream throughput via Ethernet
test interfaces. Its Download/ Upload rate is up to 1 Gbps for Ethernet. SpeedCheck uses any
IP interface, including IPv4 and IPv6, that you established for testing. Once there is data over
WiFi, it will also work over WiFi. This is an optional feature.
The ONX uses HTTP to perform a Speed Check test and requires access to an HTTP server.
This server is a generic HTTP server with minor configuration changes to support high speed
throughput. The server needs to be placed in the network in a way that will allow it to deliver
very high data rate traffic to the ONX for downstream and upstream throughput testing. VIAVI
recommends the Apache HTTP server (v 2.4) that is readily available from Apache and supports
multiple operating systems.
Apache server setup
Follow the Apache server installation instructions. To enhance the server’s ability to support
high bandwidth SpeedCheck tests, the following changes should be made to the server
configuration file.
y
File – C:\Apache24\conf\httpd.conf
y
Modification
y
EnableSendfile off {default} – Change the EnableSendfile setting to OFF
y
SendBufferSize 1000000 buffer – Add a line creating a 1000000 byte send
These changes to the configuration file are similar regardless of the operating system that
Apache is being run on, but the location of the file may change.
Once the server is configured, a very large file needs to be placed on the server that the
ONX will download during the Speed Check test. VIAVI Solutions recommends a throughput
file of at least 2 GB. The name of this file is configurable in the ONX instrument. This file is
typically located in the Apache htdocs directory.
