(Solved)
Imagine you are a consultant being asked to provide advice on the design of a new network. A
company is moving onto a new industrial estate and will be taking over the use of three buildings (A,
B and C). The buildings are only 40 metres apart and the company is aware that a network of
underground cable ducts exists linking the three buildings. All the buildings only have one floor and
each measure about 50 metres by 20 metres. The company will be operating several web servers
which are intended to be accessible from external locations by customers.
Building A contains the company's main computer room which holds the web servers and also
contains several database and fileservers used by the company's staff. The building also contains
the offices of some development staff who have very high performance desktop computers. Their
computers interactively exchange large amounts of data with some of the servers.
Building B contains the office of the clerical staff. They have relatively low performance desktop
computers and their desks are in fixed locations. The workers only exchange a small amount of data
with the servers.
Building C contains the staff cafe and a lounge area. There are also areas used to welcome
customers. Much of the building is open plan and the furniture is regularly moved around.
A. What type of networking should be installed in building A and what equipment or other
facilities would you need?
B. What type of networking should be installed in building B and what equipment or other
facilities would you need?
C. What type of networking should be installed in building C and what equipment or other
facilities would you need? How will you try to provide internet access for visiting customers
without compromising the safety of the company's own computers?
D. What type of networking and equipment should be used to link together the three buildings
and how will overall Internet access be provided for the company?
