I. Network Design

A. Network Topology

Technical Requirements

In this section, you will assess UMUC’s technical requirements. Use the information provided in the scenario to analyze the need for network topology, cables and connectors, networking and internetworking devices, wide area networking design, and computer systems. If you need more information, feel free to ask your instructor or make some assumptions. If you make assumptions, be sure to list them. This section should be used to describe the technical requirements of the task at hand. That is, you will be making explicit the requirements as you understand them, which will lead to the next section (your proposed solution).

Example ( Note: The paragraph that follows is an example. It is expected that students will use this as a reference only. Remember to include references and cite your work according to IEEE-style format.)

Secure Network Contractors believes that students and faculty health, well­being, and morale have a significant impact on the learning experience and productivity of the academic institution. Secure Network Contractors understands the following technical requirements. The university has invested in a new building that will bestow an academic ambience while providing students and faculty a world class research and learning environment. The university has hundreds of Faculty that teach and perform research within the new academic building. Faculty should be able to seamlessly transition between the newly leased building, and other buildings on the UMUC campus. Students will be required to have a similar experience as classes take place in multiple buildings across campus each day. Faculty and students will be required to print regardless of location, and therefore needs shared printing resources. All computers should be able to communicate, but the human resources department should operate on a separate network due to the sensitive and personally identifiable information they handle. We understand that the newly leased building will need to wirelessly communicate with other buildings on campus, and we will address this in the Wide Area Network (WAN) section that follows. Etc. (students should continue to explain the technical requirements).

Proposed Topology

Select one or more topologies to use for this design (i.e., star, bus, mesh, ring, and please note that the star topology is the most commonly used). This section should be used to provide the details of your proposed solution. Be specific and include the model, manufacturer, features, and cost of devices where appropriate. Students should include a visual representation of the topology selected. Topologies can be created using Microsoft Visio, or you can create a free account at draw.io (https://www.draw.io) and create diagrams. Be sure to review the types of topologies and highlight the benefits and drawbacks for each.

Example ( Note: The paragraph that follows is an example. It is expected that students will use this as a reference only. Remember to include references and cite your work according to IEEE-style format.)

Secure Network Contractors believes that from a comparison of all the types available a ring topology is the best solution based on the requirements described by the University of Maryland University College (UMUC). We believe a ring topology satisfies the requirements of forming a single, continuous pathway for data to be transmitted through each node. A ring network topology in where each node connects to exactly two other nodes. A node on a network can be considered a computer, laptop, printer, or mobile device. Each node has a unique network address, which is referred to as the Media Access Control (MAC) address. The MAC address provides… Etc. (students should continue to explain their proposal).

Justification

This section should be used to justify your proposed solution based on the requirement(s). That is, you are explaining why you proposed the solution in the aforementioned paragraph, based on the technical requirement you made explicit in aforementioned paragraph.

Example ( Note: The paragraph that follows is an example. It is expected that students will use this as a reference only. Remember to include references and cite your work according to IEEE-style format.)

Secure Network Contractors believes that a ring topology is the best solution based on the requirements described by the University of Maryland University College (UMUC). Specifically, the requirement that data flows in one direction, reducing the chance of packet collisions. The ring topology reduce the need for network servers because they are not needed to control network connectivity between each workstation. Etc. (students should continue to explain their proposal).

II. Network Addressing and Security

A. Subnetting

Overview

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 192.168.3.0. 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 192. This octet falls in between 192 and 223.

Class Octet Decimal Range
A 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 Format
A 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.

Technical Requirements

UMUC has not decided how they will use all of the physical space within the newly leased building, but the diagrams below convey the proposed end state. However, they have decided to use some of the space in the short term. In doing so, we will proceed with the proposed plan. Initially, the building will house 5 classrooms, 1 student computer lab, 1 library, and 1 office .

· In the below building diagrams, we will use Office 5 (Admissions) on the first floor. Each office will have 1 computer for staff use, with the exception of the admissions office, which will have 5 computers.

· The classrooms are labeled Classroom #1, Classroom #2, and Classroom #4 on the first floor and Classroom #1 and Classroom #5 on the second floor; each classroom will have a closet. Each classroom will have 25 devices: 23 student computers, 1 instructor computer, and 1 server in the closet, for instructional use.

· Students should consider high traffic areas for Wi-Fi, such as the sitting areas and not the classrooms. The Wi-Fi network should be segregated from the wired network and implemented on a separate Class C network. What will the network address, range, and broadcast address for this separate Class C wireless address be?

 

· In addition, there will be a student computer lab that will provide computer access to students to do their homework. The student computer lab is located on the second floor. There will be 24 computers in this lab and 1 server in the closet.

· To allow students access to library resources, the library will also have 10 computers for the general public to use and 5 computers for library staff.

· There will be two server rooms, one on the first floor and one on the second floor.

To be clear, the diagram below conveys the proposed end state. Per the aforementioned details, students must subnet based on what is needed now.

Given the aforementioned scenario, we are going to use the 192.168.3.0 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.
