Network Design Proposal (Parts 1-3)
Overview
-
You will provide detailed network design proposal. 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. In addition, computers for public use should be on a separate network. The open-wifi network should also be on a separate network.
There must be a minimum of 40 Mbps Internet connection, with a backup line capable of at least 20Mbps. Cable, DSL, or FIOS should not be used for primary Internet service.
The network has been assigned the 10.13.0.0/16 network address for all computers and devices.
Your proposal will be submitted in three major parts:
Physical Network Design

Building Details
-
The 50-year-old, two-story building has the following layout:
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 26 computers: 24 student computers, 1 instructor computer, and 1 server in the closet for instructional use.
In addition, there will be a Student Computer Lab that will provide computer access to students to do their homework. There will be 25 computers in this lab and a 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.
Finally, there are various 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.

Business Needs
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, well-being, and morale have a significant impact on the productivity of the employees and thus the overall results or output of the company. They want to invest in a facility that will provide the most return on investment while still providing a facility that employees will use.
Proposed Topology
Select one or more topologies to use for this design. This section should be used to provide details of the selected infrastructure or equipment. Include the model, manufacturer, features, and cost.
Example
We are proposing the construction of a basketball court at our campus. This can be constructed behind our main building where the current overflow parking lot is located. The court will be a full regulation-size basketball court [1]. The typical measurements of a regulation-size basketball court are as follows:

3-point line distance from the basket
23.75 ft
Key (shaded lane or restricted area) width
16 ft
Free-throw line distance from point on the floor directly below the backboard
15 ft
The court will cost approximately $20,000 and will include such features as the company logo, a state-of-the-art lighting system, and a net structure around the court.
Justification
Justify your determination that the selected topologies will meet the business needs. Use the information provided in the scenario to make the appropriate assumptions (make sure to list those assumptions). Be sure to also provide an analysis of the justification for the infrastructure or equipment.
Example
Last month, the Human Resources department conducted a survey asking all current employees which facility they would be more likely to use: basketball court, volleyball court, or tennis court. Based on the survey, 70% of our employees selected basketball, 40% selected a tennis court,and 20% percent chose volleyball court.

Explanation / Answer
Data Types. The types of data served by the network will be reports, bulletins, accounting information, personnel profiles, and web pages. The majority of the data will be text (ASCII and non-ASCII), but there will be some still graphics and possibly a small amount of voice and video (primarily for PC-based teleconferencing).
Data Sources. Data will be created and used at all end stations on the network. The data will be produced by software applications in Windows 2000, primarily Dream Weaver and Office 2000 Professional (Word, Excel, Access, PowerPoint, and Outlook). Other data sources to be supported on at least a limited basis will Windows 2000 Accessories (Paint, Notepad, etc.), NetMeeting, Media Player, and PhotoShop. Note that the network will be not be accessible from outside…
Numbers of Users and Priority Levels. At the state level, the users will be administrators, secretaries, and members of four departments. At the district levels, the users will be administrators, secretaries, and members of three departments. The maximum estimated number of users on the network at any given time is 100: 33 regular users in the State Office, 30 regular users in the North District Office, 30 regular users in the South District Office, and seven otherwise unanticipated users.
Three priority levels will be supported: management (top priority), user (medium priority), and background (low priority). Note that these designations do not correspond to administrative levels in the Maryland public education system; rather, they are network service levels. Network management processes will receive top-priority service; most network processes will receive medium-priority service; a few processes (e.g., e-mail transfers, backup, etc.) will be given low-priority service. It should be noted that network management will usually consume a small amount of the available bandwidth; this means that management and user processes will usually enjoy identical support. Background processes will also usually receive more than adequate service, but they will be delayed as needed to maintain support for management and user services.
Transmission Speed Requirements. The network is to be transparent to the users. Thus, remotely executed applications, file transfers, and so forth should ideally appear to operate as quickly as processes executed within an end-station. Interviews with users to ascertain their needs and expectations indicate that an average throughput of 20 mbps per user within each LAN and 10 mbps per user between LANs will more than support the needed performance in most cases (teleconferencing being the possible exception).
Load Variation Estimates. Interviews with users and observation of LAN use at the three locations yielded data on hourly average and peak loads from January to March, 2001. The data are tabulated in the appendix. The data indicate that the highest average traffic volume will occur from 8:00 a.m. to 6:00 p.m., Monday through Friday. The peak network traffic volume is expected at two times during the day: 8:00 a.m. to 12:00 noon and 3:00 p.m. to 5:00 p.m. At night and on weekends the network traffic is minimal except for the daily backups of the PCs to the LAN servers in the districts and several batch data transfers anticipated from the districts to the State Office. The data indicate the following network design parameters:
· The average required throughput on any LAN during work hours (7:00 a.m. to 6:00 p.m.) will be only about 0.2 mbps.
· The average required throughput on the WAN during work hours (7:00 a.m. to 6:00 p.m.) will be only 0.04 mbps.
· The peak expected traffic load on any LAN will be about 10.4 mbps.
· The peak expected traffic load on the WAN will be about 6.4 mbps.
Of course, to avoid user complaints, the network is designed for the peak traffic loads, not the average throughput.
Storage Requirements. Storage requirements need to be large enough to store all student, teacher, and state data (note: student data are data about students, not data generated by students). Interviews and observations of users’ present and anticipated storage requirements indicate that each user will need an average of 100 MB of server space (in addition to secondary storage on local PCs); the maximum estimated server-side storage requirement per user is about 1 GB. Additionally, the network operating system will occupy about 500 MB on each LAN server. Taking price-performance issues into account, each PC will have a minimum storage capacity of 10 GB, each LAN server will have a minimum storage capacity of 20 GB. A main data server in the State Office will have a 36 GB capacity.
Reliability Requirements. In keeping with user expectations and industry standards, both the LANs and the WAN are expected to operate at 99.9% uptime and an undiscovered error rate of .001%.
Security Requirements. A firewall will be used so unauthorized users will be restricted. Part of the security will be Users accounts and passwords that will give limited access. There will be different access capabilities for network managers and users.
Existing Network. There is no existing network.
