Building dimensions: length: 240 feet, width: 95 feet, height: 30 feet

The building will house six computer labs that will be used for instruction. In the building diagrams above, the labs are labeled Classroom #1, Classroom #2, and Classroom #4 on the first floor and Classroom #1, Classroom #2, and Classroom #5 on the second floor; each computer lab will have a closet. Each lab will have 25 computers: 23 student computers, one instructor computer, and one server in the closet for instructional use.

To allow students access to library resources, the library will also have 20 computers for the general public to use and five computers for library staff.

Finally, there are 7 offices in the building. Each of these offices will have one computer for staff use, with the exception of the admissions office, which will have five computers. There will be two server rooms, one on the first floor and one on the second floor.


 Provide a detailed network design proposal. Your task is to design the network for this new building with the following criteria:

•  Each Classroom Computer Lab will be on a separate network (i.e., subnet). The Library Computer Lab will be on a separate network, and the Office / Admissions computers will also be on a separate network. Finally, the open-WiFi network should be on a separate network, but can use a private IP address range (i.e.,

•  There must be a minimum of 40 Mbps Internet connection, with a backup line capable of at least 20 Mbps. Cable, DSL, or FIOS should not be used for primary Internet service.

•  The network has been assigned the network address for all computers and devices.

Your proposal will be submitted in three major parts:


1.  Physical Network Design

2.  Network Addressing

3.  Network Services Design


Physical Network Design


In this section, address each of the following.

Define the topology that will be used.

Select the appropriate network media.

Select the appropriate network connecting devices, including network security devices.

Select the appropriate computer systems to use to support the network design.

Determine a physical layout of the computers on the floor plan, along with the network wires (network wiring diagram).

Provide justifications for each element of your network design (numbers 1–4 above).

Physical Network Design: 1. Define the topology that will be used. It will be an extended star (tree) topology. 2. Select the appropriate network media to use. The best network media to use would be CAT6 STP. 3. Select the appropriate network connecting devices to use. This will be a fully routed network so all subnets will have to be connected to 2 routers All computers, servers and devices will be connected to switches. Switches will be located at each room. Routers will be located at the library (first floor) and the student computer lab (second floor) There will a wireless access point in the Student Lobby area. One Internet Firewall on the first floor’s server room for internet access connected to the T1 modem. One firewall to block unauthorized access from students and staff to the server (creating a DMZ for the servers). 4. Physical layout of the computers on the floor plan. 5. List of additional servers or network devices needed to implement the network. The ideal scenario would consist of a pair of Access Control Servers (like MS Domain Controllers or Samba Domain Controllers for example) to control access to resources with user accounts. A database server (SQL or Oracle for ...
