38 Chapter 1: Design Overview
network applications. Freddy, director of sales, recommends the hierarchical model. He says
that this model will solve just about any problem. Megg thinks the team should take a closer
look at the business requirements before making a technical recommendation. Millie
recommends that the network have lots of bandwidth to satisfy the users' desktop application
requirements.

Scenario 2
WSOL has just purchased four other radio stations to create a regional radio conglomerate
called Radio 1000:
WSOL headquarters, New York
Satellite branch, Manhattan
Satellite branch, Queens
WLAN (purchase 1), Boston
WNET (purchase 2), Baltimore
WCAP (purchase 3), Washington
WGAS (purchase 4), Atlanta
WSOL wants to establish full connectivity between all sites. WSOL would like one site to be
able to back up the main site in the event of equipment failure. WSOL requires that the
submitted design be scalable, because it expects to purchase additional stations in the future as
soon as Congress passes an amendment to the Telecommunications Act. WSOL also wants the
network to be cost-effective, to ensure that the investment will yield a good return to its
investors.
Freddy Forklift, Director of Sales at RouteitRight, has proposed a full-mesh solution for
WSOL. He says this solution will provide the redundancy and scalability that WSOL has
requested. Figure 1-15 depicts the full-mesh design.
As you will see in chapters that follow, RouteitRight is an unconventional group. In this
instance, the Director of Sales does not recommend the model because he believes it to be
technically sound. He simply wants to sell the hierarchical model because sales of the
hierarchical model will mean big money for the sales team.
