dash

An MPEG/DASH client-server ns3 module for simulating rate adaptation algorithms over HTTP/TCP.

This module was built for generating the simulation results in the following papers:

Installation instructions

Install ns3 on you system, using the instructions like from here: https://www.nsnam.org/wiki/Installation#Installation.
Download the module into the contrib directory, with the following commands:
```
cd ns-3-dev/
cd contrib/
git clone https://github.com/djvergad/dash.git
```
A new directory named dash should be created in the src directory
Re-configure ns3 and enable examples. From the ns-3-dev directory, type:

For ns3 version 3.36 and above type
```
./ns3 configure --enable-examples
```
For versions 3.35 and below type:
```
./waf configure --enable-examples
```

Now the setup is complete. Validate by running an example:

For ns3 version 3.36 and above type

./ns3 run 'dash-example --users=3 --algorithms=ns3::FdashClient --linkRate=1000Kbps --bufferSpace=10000000'

For versions 3.35 and below type:

./waf --run 'contrib/dash/examples/dash-example --users=3 --algorithms="ns3::FdashClient" --linkRate=1000Kbps --bufferSpace=10000000'

There should be output similar to the following:
