INSY 3303: Lab 6
This is an individual assignment. No late assignments will be accepted.
DUE: ON / BEFORE April 23
Computer Dynamics is a microcomputer software development company that has a 300computer network. The company is located in three adjacent five-story buildings in an office
park, with about 100 computers in each building. The LANs in each building are similar, but one
building has the data center on the second floor. There are no other office locations. The current
network is poorly designed for its current needs and must be completely replaced. Develop a
logical design for this enterprise campus that considers the seven network architecture
components. There are no other campuses, so you can omit WAN access. You will need to make
some assumptions, so be sure to document your assumptions and explain why you have designed
the network in this way.
Shown below is a good example of a typical configuration for a network of this type.
Building Block Network Design (Chapter 6) is an interactive process in which the designer
examines users’ needs, develops an initial set of technology designs, assesses their cost, and
then revisits the needs analysis until the final network design emerges.

Lab 6 Video Lecture (week 11)
Note: The LAN would typically be designed as a physical star topology connecting the
computers on each floor with UTP cabling to a switch. A wireless network is recommended in
each building in addition to the wired network. Based on the size of the buildings, number of
users, and the fact that a wired network is already in place, the company could get by with
802.11ac access points on odd numbered floors (3 per building). These would probably provide
enough wireless access to support the users.
The switch(es) on each floor would connect to the main switch on the first floor of each building,
which would then connect to a router in that building. The connections among the switches
would be fiber.
It is recommended to use multi-mode fiber optic cable to connect all three buildings to the
others. One of the three buildings would be designated as the main building, as it contains the
data center on the second floor. Each of the respective building LANs would connect into a
device like a data switch that had a fiber uplink port. At the main building, the other two
buildings would be terminated via the other end of the fiber into ports on the main campus data
Any needs for connectivity to the outside, for example the Internet, could be supported by
connecting the gateway router directly into a port on the main data switch. The router could
connect to a CSU which brought into the campus network a high-speed circuit. In this design
everyone on campus could have Internet connectivity and also connect to any server or printer
physically located at any of the other buildings.
The data center would contain the e-commerce edge. This would consist of at least the web
server that allows potential and existing customers to view their website.
