Assignment

Background:

Your small business received a contract award to upgrade the network. Right now, each department has its own network with its own DSL connection. Students and faculty members have to access each department through the Internet to access resources. Also, each department has added computers by using switches and repeaters.

Some of the major problems of the networks are:
High administrative cost due to a lack of centralized network management
Lack of data backup on servers
High rate of collisions
Slow speed due to a large broadcast domain
Lack of backup WAN connectivity
Inadequate network security
Use of manually assigned IP addresses
Here is a breakdown of your assignment (the paper should be no more than three pages, excluding diagrams):

Building dimensions:
Length: 240 Feet
Width: 95 Feet
Height: 30 Feet

The 40-year-old two-story building has the following existing layout:

There will be six computer labs that will be used for instruction. Each of these labs will have 21 computers (20 student computers and 1 instructor computer). Each of these labs will also have a server in the closet located inside the lab.

In addition to the six computer labs, there will also be a Student Computer Lab that will provide computer access to students to do their homework. There will be 30 computers in this lab and a server in the closet.

The library will also have some computers to allow students access to the library resources. There will be 10 computers for student's use in the library, and 5 computers for Library staff.

There are four lecture classrooms in the building. Each of this room will have a computer for instructor's use.

Finally, there are various offices in the building. Each of these offices will have one computer for the staff use, with the exception of the Admission office that will have 5 computers for staff use.

Equipment Inventory

Workstation Placement	Number of Workstations	Users	Total WS
6 Instructional Computer labs	21 WS	Student and Instructor	126 WS (based on 20 WS for students and 1 WS for instructor on each lab * 6 labs)
Student Computer Lab	30 WS	Student	30 WS
6 Various Offices	1 WS	Staff	6 WS
1 Admission office	5 WS	Staff	5 WS
Library	10 WS	Student	10 WS
Library	5 WS	Staff	5 WS
4 Instructional Classrooms	1 WS	Instructor	4 WS Total
Server	?	Staff	To be determined by students
Network Connecting Devices	?	IT Staff	To be determined by students
Printers	?	Staff	To be determined by student
Printers	?	Instructional	To be determined by student

Two server rooms have been allocated, one on the first floor and one on the second floor.

Your task is to design the network for this new building with the following criteria:

Student-accessed computers should be on separate network from the staff-accessed computers. There should be at least 3 separate networks: Administrative, Instructional, and Public. All staff-accessed computers will be on the Administrative network. The computers in the instructional computer labs and classrooms that will be used for classes should be on the Instructional network. The wifi and the computers in the student lobby should be in the Public network.

The whole building will share one Internet access connection (T-1 link from Telekom). This connection will come into the Server Room on the first floor. The Public IP address for the router here is 191.1.15.1

Security is very important for UMUC as we have to protect students and employees data as well as any intellectual property that UMUC has on the servers and computers.

The network has been assigned the 10.15.0.0 network address for all computers and devices.
The network should use physical cable (not wireless), but do provide wireless access in the Student Lobby area.

Submission should include (in no more than three pages, excluding diagrams and references):

Network Addressing:

Define the subnet (based on: rooms, floor, department, or other criteria).

For each subnet, explain which devices/groups/users/rooms will be on this subnet, define the network address, subnet mask, and available IP addresses to be used by computers or devices.

Physical Network Design:

Define the topology that will be used.
Select the appropriate network media to use.
Select the appropriate network connecting devices to use.
Physical layout of the computers on the floor plan.
List of additional servers or network devices needed to implement the network.
Justifications for your network design (number 1 - 5 above)

Network Diagram:

The diagram can use the supplied floor diagrams to depict your layout of equipment within the facility.

You can also choose to create a ‘blueprint' or layout of just the equipment referring back to the room layouts of the supplied diagram and show network addressing and physical layout.

The diagram does not count against the maximum number of pages.

Logistics:

Two to three double-spaced, typed, fully justified (font size 12; font face Times, Arial or Verdana), with 1 inch margins all around, pages consisting of sentences and paragraphs to describe your fictitious company and your proposed network design requirements
One additional page to use/provide a diagram of your proposed network design

For each element in your proposed network design, you must explain why you made the choice in at least 1-2 sentences

The paper must be grammatically correct and use APA styles refer to (Maryland APA website https://www.umuc.edu/library/libhow/apa_examples.cfm) for help in meeting APA style and creating references

You will be evaluated on your ability to

Implement appropriate IP addressing scheme

Select and justify appropriate cable media that includes the length of each cable segment and number of nodes on each segment
Select and justify appropriate topology such as star, bus, or ring for your network
Select and justify of your selected network equipment
Select and justify appropriate network services to meet network requirements
Select and justify security implementation for the network
Use proper grammar, formatting, network terminology, and reference citations

Feel free to use any drawings or attachments, and assume any number of computers or users (not when provided here). You will be graded on the basis of right media, topology and knowledge of network concepts.
