 Network Design Paper
UMUC has recently acquired a building in Frederick, Maryland. This new building will house some administrative offices, lecture rooms, library, and computer labs.

 

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 five 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.

 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 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 Verizon). 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:
1. Define the subnet (based on: rooms, floor, department, or other criteria).
2. 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:
1. Define the topology that will be used.
2. Select the appropriate network media to use.
3. Select the appropriate network connecting devices to use.
4. Physical layout of the computers on the floor plan.
5. List of additional servers or network devices needed to implement the network.
6. Justifications for your network design (number 1 – 5 above)

 You will be evaluated on your ability to

o Implement appropriate IP addressing scheme
o select and justify appropriate cable media that includes the length of each cable segment and number of nodes on each segment
o select and justify appropriate topology such as star, bus, or ring for your network
o select and justify of your selected network equipments
o select and justify appropriate network services to meet network requirements
o select and justify security implementation for the network
o 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.

 
 

Virtual Business in Global Marketing

  1. Read content resources. Above you developed a Code of Virtuous Leadership, but this is really the first step to virtuous decision-making. Sometimes the ethical situations confronting the leader are clearly black and white and application of the Code is easy to accomplish. However, sometimes the ethical pitfalls are much more convoluted and obscured. In these situations, it is appropriate for the leader to employ a systematic analysis approach. Click on the link below to Paine’s Moral Compass which is such an approach. Paine Manager’s Compass for decision-making | Profolus  Review the decision-making lens and your Code of Virtuous Leadership and respond to the Key Questions below
  2. Write an initial response to the following key question(s) or prompt(s):
    1. In which of Dr. Paine’s lenses are elements of your Code most likely to be beneficial and why?
    2. Should your Code of Virtuous Leadership and a decision-making protocol such as Paine’s be included in you PBL team’s report to your company’s Board of Directors and why?
    3. What might be points of resistance by your company’s leadership in application of your Code and/or a protocol for ethical decision-making?
  3. Support your statements with evidence from the required studies and your research. Cite and reference your sources in APA style.

4. The purpose of ethics is to ensure that people are treated right and fairly, and that business decisions are in the interest of employees and customers alike. Ethics is about acting with fairness, integrity and respect for the rights of others. It is about valuing people and treating them in the right way at all times, so that they trust you and want to do business with you. People don’t feel cheated or dissatisfied when a leader acts in an ethical manner and gives his or her employees the opportunities that they deserve and want. When leader behave ethically, they’ll naturally be a great leader (Alshehri & Elsaied, 2022).
