Currently working on week 3 assignment

I started working on the week 3 assignment a short while ago. For the assignment, I need to interview the manager of a wide area network (WAN) or build a hypothetical WAN and analyze the network's functionality. Since it is usually challenging to get managers and companies to participate (and it is late anyway), I will build a hypothetical WAN.

I started reading & selecting resources (articles, books etc.)...

Some resources looked good, but I could not access/download the full paper. I hate when that happens!....
