Overview

Students use a new version of the Internet Simulator configured with simulated IP addresses and routers to explore the benefits (and potential security concerns) associated with routing traffic across the Internet. Students should see that messages go through many different routers, may not always take the same path to reach a destination, and all the traffic is publicly viewable!
