Application instances reside on the Client and Server

Client side can invoke/control both Upload and Download

Single server instance can support request from multiple clients

Key Parameters:

Transmission

Packet Length

Test Duration

Server Destination

The Three types of Test that WINDS can perform are:

UDP Test

FTP Test

Ping Test


1. WINDS - CONFIGURATION

Winds comes packaged with an installer, and must be installed on every laptop/client that is intended to operate WINDS on as well as the server to which these client will communicate

Install the Package and make the appropriate choice to use application run as a Wireless Terminal. This can always be changed by the settings: Configure-- adapter

The next step is to configure the adapter: Select Configure-- adapter. The following screen will appear

Click on New and assign a name to each adapter to be used for testing


The final step is to configure the logging options. Select Configure---Logging The following screen will appear

IPERF


Background

IPERF is commonly used network testing tool that can create UDP and TCP data streams and measure the Throughput of a network of a network that is carrying them

It has a Client and Server functionality, and can measure the Throughput between the two ends either unidirectional or bi-directional

It is open source software and runs on various platforms including Linux, Unix and Windows

When used for testing UDP capacity, Iperf allows the user to specify the datagram, size and provides results for the datagram Throughput and the Packet Loss

Typical Iperf output contains a timestamped report of the amount of data transferred and the Throughput measured

iperf reports bandwidth, delay, jitter, datagram loss

Make sure iperf program is install on your PC and Server

Execute iperf from where the program resided


Iperf Set up

Here is a diagram where Iperf is installed on a Linux and Microsoft Windows machine.

Linux is used as the Iperf client and Windows as the Iperf server. Of course, it is

also possible to use two Linux boxes.


Iperf execution command

Measurement Report

f #[kmKM] show the result by kbits, mbits, Kbytes and Mbytes respectively

i [n] seconds between periodic bandwidth reports

t test duration (default 10 sec)

n #[KM] number of bytes to transmit (instead of -t)

Dual test

d Do a bidirectional test simultaneously

l [KM] length of buffer to read or write (tcp:default 8kb udp:1470bytes)

P [n] connection restriction number


Iperf arguments

Downlink

At the server, execute the following (Transfer Command)

$iperf c -u b 60M t240 l1400

At the client, execute the following (Listen Command)

C:\iperf s u
