I. Physical Network Design
A. Network Topology
In this section, you will assess the business needs of the company. Use the information provided in the scenario to analyze the need for infrastructure or equipment. If you need more information, feel free to ask your instructor or make some assumptions. If you make some assumptions, be sure to list them. This section is not about the actual infrastructure or equipment, but it should discuss the business needs of the company.
Example
ABS Enterprises believes that employees’ health, wellbeing, and morale have a significant impact on the productivity of the employees and thus the overall results or output of the company. The company wants to invest in a facility that will provide the most return on investment while still providing a facility that employees will use. The company has 20 employees and wants needs one or more servers and two printers. All computers should be able to communicate, but the HR staff of 5 needs to be on a separate network due to the sensitive information on their PC’s.
Proposed Topology
Select one or more topologies to use for this design (star, bus, mesh, ring- Please note that the star topology is the most commonly used). This section should be used to provide details of the selected infrastructure or equipment. Include the model, manufacturer, features, and cost. Below is an example topology. Topologies can be created using Microsoft Visio, or you can create a free account at gliffy.com and create diagrams.
B. Network Media
Note: (Choose wired or wireless)
Business Needs
Assess the business needs.
Proposed Network Media (include network wiring diagrams)
Select one or more network media to use for this design.
Justification
Justify your determination that the selected media will meet the business needs.
C. Network Devices
Business Needs
Assess the business needs.
Proposed Network Devices
Select network devices to use to implement the design. Include setup and location information for the devices. Provide a comprehensive list of devices, including the quantity of each device needed.
Justification
Justify your determination that the selected network devices will meet the business needs.
Example: I selected a Cisco 2621 Router in order to connect the HR users to the rest of the company’s employees
D. Network Security Devices
Business Needs
Assess the business needs.
Proposed Network Security Devices
Select network security devices to use to secure the network. Include setup and location information for the devices. Provide a comprehensive list of devices, including the quantity of each device needed.
Justification
Justify your determination that the selected network security devices will meet the business needs.
Example: I selected a Cisco ASA 5510 Firewall in order to protect the company’s network.
E. Computer Systems
Business Needs
Assess the business needs.
Proposed Computer Systems
Select computer systems (servers) to use to implement the network design. Include setup and location information for the devices. Provide a comprehensive list of devices, including the quantity of each system needed.
Justification
Justify your determination that the selected systems will meet the business needs.
Example: I selected Windows 10 Professional for the operating system, because it is the newest, most secure, and stable version of Windows for end users.
II. Network Addresses Design (in its entirety)
A. Subnetting
Subnetting is a process of breaking a large network into small networks known as subnets. Subnetting happens when we extend the default boundary of the subnet mask. Basically we borrow host bits to create networks (i.e., subnets).
We have been assigned the network address 199.1.2.0. Based on the chart below, we know this is a Class C address. This is determined by observing the first octet of the IP address, which is 199. This octet falls in between 192 and 223.
Class / Octet Decimal RangeA / 1 - 126
B / 128 - 191
C / 192 - 223
Each class has a predefined default subnet mask that tells us the octets, which are already part of the network portion, as well as how many bits we have available to work with.
Class / Subnet Mask / FormatA / 255.0.0.0 / Network.Host.Host.Host
B / 255.255.0.0 / Network.Network.Host.Host
C / 255.255.255.0 / Network.Network.Network.Host
CIDR (Classless Inter Domain Routing)
CIDR is a slash notation of the subnet mask. CIDR tells us the number of on bits in a network address.
●Class A has default subnet mask 255.0.0.0. that means first octet of the subnet mask has all on bits. In slash notation it would be written as /8, means address has 8 bits on.
●Class B has default subnet mask 255.255.0.0. that means first two octets of the subnet mask have all on bits. In slash notation it would be written as /16, means address has 16 bits on.
●Class C has default subnet mask 255.255.255.0. that means first three octets of the subnet mask have all on bits. In slash notation it would be written as /24, means address has 24 bits on.
Scenario
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.
Methodology
Given the aforementioned scenario, we are going to use the 199.1.2.0 network and create a total of 8 subnets, with 25 hosts on each subnet. The chart below describes structures the scenario to include each subnet and required hosts.
Subnet Description / Required HostsClassroom 1 Computer Lab / 25 Computers
Classroom 2 Computer Lab / 25 Computers
Classroom 3 Computer Lab / 25 Computers
Classroom 4 Computer Lab / 25 Computers
Classroom 5 Computer Lab / 25 Computers
Classroom 6 Computer Lab / 25 Computers
Library Computer Lab / 25 Computers
Office / Admissions Network / 14 Computers
Using the How to Subnet a Network Video provided in CMIT 265 LEO - Content - UMUC Network Design Proposal, complete the following chart.
Subnet / Network Address / Host Address Range / Broadcast AddressSubnet Mask: 255.255.255._____

III. Network Services Design
A. Network Services
Business Needs
Assess the business needs
Proposed Network Services
Determine and list the network services needed to implement the design. Provide setup and licensing information (as necessary).
Justification
Justify your determination that the network services are needed and will meet the business needs
Example: There needs to be a DHCP, DNS, File, and Active Directory Server on the network. Please example why these servers are needed and what role they will play.
.
B. Network Security Measures
Business Needs
Assess the business needs
Proposed Network Security Measures
Outline network security measures needed in the design. This includes training, monitoring, and maintenance procedures. Provide implementation details of these measures.
Justification
Justify your determination that the network security measures are needed and will meet the business needs.
Example: Discuss Patching. How will the systems in this company’s network be updates? Discuss Firewall rules, for example all traffic will be allowed out or just 80 and 443 traffic will be allowed out. What version of Anti-Virus should be used on machines?
