Homework 5 - network performance measurements (DRAFT)
In this homework, we'll use a set of tools for measuring, analyzing and reporting network performance. You will measure the pairwise round-trip time between 100 hosts: a total of 9900 pairs, on three different occasions, and analyze the results.
Prerequisites
- Register your host with Tomas. Send an email with subject "hw5 mac registration". In the body, type your netid, followed by a space, followed by the mac addresses (wired and wireless) of your computer.
- Create a planetlab account. Go to create account and fill in your details. I will approve it as soon as I get a chance.
- If you don't already have one, generate an ssh key. In your terminal, run "ssh-keygen".
- Once your account is enabled, log in to planet-lab.org and add your key (you'll find it in ~/.ssh/id_dsa.pub) to your account.
Tips
- Some servers will be down for maintenance, or have other problems. To have ssh give up after a short time, use a ConnectTimeout option "ssh -o ConnectTimeout=1 google.com".
