CDN-Perf

A project for a course titled "Measuring Internet Performance". The focus is on comparing the performance characteristics of websites such as YouTube to that of the servers which deliver their actual content.

Requirements

Ubuntu

sudo apt-get build-essential traceroute tcpdump python3-dev python3-pip
pip install -r requirements.txt (virtual environment suggested: link)
Ensure that tcpdump has permissions to access network device: instructions (N.B. requires reboot after the steps are complete)
Ensure traceroute has permissions to send ICMP packets: sudo chmod u+s `which traceroute` and similarly for ping if necessary.

Windows

WinDump installed or in the current directory
[Python 3] (https://www.python.org/downloads/)
pip install -r requirements.txt (virtual environment suggested: link)

Python modules

The tests were run with the following version of each module (should the tests need to be replicated):

psutil==4.3.0
requests==2.11.1
youtube-dl==2016.8.13

To run

source <path_to_virtual_environment>/bin/activate if using a virtual environment
Ensure all the URLs of the videos you want to test are in a text file (see urls.txt for an example)
python cdn_perf.py <path_to_urls_file>

Output

A file data-<timestamp>.csv will be created which contains all test results.
