CS 244 '15: Reproducing Mosh Paper Results
Team:
Kevin McKenzie (kmckenzi)
Patrick Harvey (p1harvey)
Setting up the test server on EC2:
Create an EC2 instance following the intstructions listed here:
http://web.stanford.edu/class/cs244/ec2setup.html
Select the AMI CS244-Spr15-Mininet or ami-cba48cfb on us-west-2
Select the c3.large instance type
Configure the security group to allow SSH access
Log into your EC2 instance and verify mininet by running:
sudo mn --link tc,bw=10 --test iperf
For more detailed instructions, see the link above.
Setup:
git clone https://github.com/kjtmckenzie/mosh_test.git
cd mosh_test
sudo ./setup.sh
Running the setup.sh script will install all the relevant packages
needed for the Mosh experiment. It may ask you for a "y" or "yes"
to confirm the package installation.
Run the experiment:
sudo ./run.sh
This will take roughly 2 hours, and it will generate 5 graphs in the
mosh_test directory: 3G.png, 3G_FLAKY.png, 4G_LTE.png, 4G_LTE_FLAKY.png
and WIFI.png. These show the same results of the Mosh paper for
various mobile technologies. The original Mosh-paper only included
results for 3G, so the 3G and 3G_FLAKY results are the most
representative of the results were are trying to emulate.
We used the following statistics gathered from real-world data
by using the FCC Speed Test app at various locations around Escondido
Village.
Note: DELAY measures 1/2 of the RTT. JITTER is the amount any
one link's bandwidth can change. A JITTER_FACTOR of .5 means
a link could go from .5x bandwidth to 1.5x bandwidth. Bandwidth
and delay are in milliseconds.
