Session 8: Route tracing, collision avoidance and scene setting

In this session you will be looking at a way of tracing the route used by an IP packet. You will also look at the method used in Wi-Fi for distributing access to the radio channel among users. Finally, as scene-setting for the next eight sessions, you’ll briefly look at some of the ways networking in large enterprises differs from networking in homes and small businesses.

By the end of this session, you will be able to:

• use traceroute and interpret traceroute responses
• understand the principles of multiple access and collision avoidance in Wi-Fi
• understand how enterprise-scale networking differs from home networking.
