title: How to calculate maximum, minimum and average RTT of ping in python?
body: <p>It's one question of our assignment.<br>
  I have calculated RTT using
  <code>time.clock()-InitialTime</code> in python, but I got stuck when it comes to max, min, avr RTTs.<br>
  What should I do? I'm thinking it has to do with some packet size?</p>
