Assignment 01

General Guidelines
1. A Cover page or title page – You should always attach a title page to your assignment. Use
previous page as your cover sheet and make sure all the details are accurately filled.
2. Attach this brief as the first section of your assignment.
3. All the assignments should be prepared using a word processing software.
4. All the assignments should be printed on A4 sized papers. Use single side printing.
5. Allow 1” for top, bottom , right margins and 1.25” for the left margin of each page.

Word Processing Rules

1. The font size should be 12 point, and should be in the style of Time New Roman.
2. Use 1.5 line spacing. Left justify all paragraphs.
3. Ensure that all the headings are consistent in terms of the font size and font style.
4. Use footer function in the word processor to insert Your Name, Subject, Assignment No, and
Page Number on each page. This is useful if individual sheets become detached for any reason.
5. Use word processing application spell check and grammar check function to help editing your
assignment.

Important Points:

1. It is strictly prohibited to use textboxes to add texts in the assignments, except for the
compulsory information. eg: Figures, tables of comparison etc. Adding text boxes in the body
except for the before mentioned compulsory information will result in rejection of your work.
2. Avoid using page borders in your assignment body.
3. Carefully check the hand in date and the instructions given in the assignment. Late submissions
will not be accepted.
4. Ensure that you give yourself enough time to complete the assignment by the due date.
5. Excuses of any nature will not be accepted for failure to hand in the work on time.
6. You must take responsibility for managing your own time effectively.
7. If you are unable to hand in your assignment on time and have valid reasons such as illness, you
may apply (in writing) for an extension.
8. Failure to achieve at least PASS criteria will result in a REFERRAL grade .
9. Non-submission of work without valid reasons will lead to an automatic RE FERRAL. You will
then be asked to complete an alternative assignment.
10. If you use other people’s work or ideas in your assignment, reference them properly using
HARVARD referencing system to avoid plagiarism. You have to provide both in-text citation and
a reference list.
11. If you are proven to be guilty of plagiarism or any academic misconduct, your grade could be
reduced to A REFERRAL or at worst you could be expelled from the course

Assignment Brief and Guidance:

Scenario

Alliance Health is a technology-enabled solutions company that optimizes the revenue cycle of the US
healthcare industry where its global delivery center is located in Colombo. The company is planning to
expand their business operations with their latest branch at Matara and wants it to be one of the
state-of-the-art companies in Matara with the latest facilities.

Assume you have been appointed as the new network consultant of Alliance Health to plan, design
and restructure the existing network. Prepare a network architectural design and implement it with
your suggestions and recommendations to meet the company requirements.
The floor plan of the head office in Colombo is as follows:
Floor 1:
 Reception area
 Sales & Marketing Department (10 employees)
 Customer Services Area – with Wi-Fi facilities

Floor 2:
 Administration Department (30 Employees)
 HR Department (20 employees)
 Accounting & Finance Department (15 employees)
 Audit Department (5 employees)
 Business Development Department (5 employees)

Floor 3
 Video conferencing room
 IT Department (60 employees)
 The Server Room
The floor plan of the branch in Matara is as follows:
Floor 1:
 Reception area
 Customer Services Area– with Wi-Fi facilities

Floor 2:
 Administration Department (10 Employees)
 HR Department (7 employees)
 Accounting & Finance Department (8 employees)
 IT Department (50 employees)

Following requirements are given by the Management.

 All the departments must be separated with unique subnet .

 The conferencing room of the head office and Customer Services Areas of each
branch are to be equipped with Wi-Fi connections .

 Connectivity between two branches (Head Office and Matara) which would allow
the intra branch connectivity between departments. (Use of VPN is not compulsory)

 The necessary IP address classes and ranges must be decided by the network
designer and should be used for all the departments except the server room .

 Number of servers required for the Server room need to be decided by the
Network designer and should be assigned with 10.254.10.0/24 subnet. (Uses static
IPs )

 Sales and Marketing Team also needs to access Network resources using WIFI
connectivity.

(Note: Clearly state your assumptions. You are allowed to design the network according to your
assumptions, but main requirements should not be violated)
Activity 01
 Discuss the benefits and constraints of different network system types that can be
implemented in the Matara branch and the main IEEE Ethernet standards that can
be used in above LAN and WLAN design.

 Discuss the importance and impact of network topologies and assess the main
network protocol suites that are used in network design using examples.
Recommend suitable network topologies and network protocols for above scenario
and evaluate your answer with valid points.

Activity 02
 Discuss the operating principles of network devices (Ex: Router, Switch, Etc.) and
server types that can be used for above scenario while exploring different servers
that are available in today’s market with their specifications and recommend
server/servers for the above scenario and justify your selection with valid points.

 Discuss the inter-dependence of workstation hardware and networking software

and provide examples for networking software that can be used in above network
design.

Activity 03
 Prepare a written network design plan to meet the above-mentioned user
requirements including a blueprint drawn using a modeling tool (Ex: Microsoft Visio,
EdrawMax) and test and evaluate the proposed design by analyzing user feedback
with the aim of optimizing your design and improving efficiency.

(Support your answer by providing the VLAN and IP subnetting scheme for the above
scenario and the list of devices, network components and software used to design the
network for above scenario and while justifying your selections.)
 Install and configure Network services, devices and applications (Ex: VLAN,WiFi,
DNS,Proxy, Web, Etc.) according to the proposed design to accomplish the user
requirements and design a detailed Maintenance schedule for above Network.

*Note: - Screen shots of Configuration scripts should be presented.

Activity 04
 Implement a networked system based on your prepared design with valid evidences.

 Develop test cases and conduct verification (Ex: Ping, extended ping, trace route,
telnet, SSH, etc.) to test the above Network and analyse the test results against the
expected results.

 Recommend potential future enhancements for the networked system with valid
justifications and critically reflect on the implemented network, including the plan,
design, configurations, tests and the decisions made to enhance the system.
