Attributes 3, 4 & 5 Weight 25% of overall unit assessment Suggestion This assignment is developmental and cumulative. You are strongly

advised to start doing this assignment from study Week-7 in your study. Leaving your starting date to the week before the due date is a very poor strategy for success in the unit.

1 Problem Context uSoft.com is a private biomedical software development company. It has two branches spread over the Gold Coast region. The company’s local area network (LAN) is captured in the topology below:

SCHOOL OF BUSINESS AND TOURIMS

CSC00240 – Data communication and Networks S3/2018

The company has expanded, and it has decided to redevelop its HQ’s existing LAN (see the above diagram) to achieve the company’s following business and technical goals.

 The Business goals:

 Improved communications, wireless, VoIP, etc.  Protect company information

 Technical goals:

• Scalability – company plans to increase employee by 15% in next 12 months; • Remote Access- employees have access to company resources from both company and

home (different servers); • Performance – network performance must be high • Security – protection of company information and other IT assets • Flexibility- network should be flexible enough to create logical grouping as required. • Availability – wireless network access is available in all employees as well as some outdoor

areas for software developers and employees

You are free to make as many assumptions you wish regarding the existing organizational structure including management hierarchy, business requirement, etc. which will need to be documented in the appropriate sections of your report.

You are contracted by the company to help with the network redevelopment.

2 The company HQ Structure The company HQ has 6 departments: Software Development, Solution Design, Customer Support, Sales, Finance and Human Resource detailed as follow:

Software Development Number of employee 10X Each employee has 01 PC + 01 IP Phone The department has 3 servers Solution Design Number of employee 9X Each employee has 01 PC + 01 IP Phone The department has 2 servers Customer Support Number of employee 6X Each employee has 01 PC + 01 IP Phone The department has 1 server Sales Number of employee 5X Each employee has 01 PC + 01 IP Phone The department has 1 server Finance

Number of employee 3X Each employee has 01 PC + 01 IP Phone The department has 1 server Human Resource Number of employee 2X Each employee has 01 PC + 01 IP Phone The department has 1 server

X is the first digit of your student ID

The uSoft HQ is located in a 6-stories building with the floor plan as pictured below (you are welcome to redesign the floor plan if you wish). In HQ, the company plans to put each department on a separate floor. However, there is also an option to have the software and solution design developments to occupy two floors while other departments will share the other four. The network is therefore should be flexible enough to meet both options.

3 The Task Your task in this assignment is to propose and document

 Requirement engineering (The analysis of user requirements for the company HQ’s local area network (LAN))

 A logical design for the HQ LAN  An IP address plan for the HQ LAN according to the proposed design  Network diagrams

Ass 2 is a basis of your design. The three routers form the core in what is known as a campus design. Ass 3 now takes you to a standard industry design which uses this campus design. We add (in the right place) network devices such as firewalls to protect the network. WiFi is a necessary part of a modern network. As the HQ is connected to the branch offices, you will need to show how the HQ is connected to the branch offices. Your textbook has this information shown as Best Practice Design for LAN (campus). There are two ways of presenting a network, the logical view and the physical view. Please read the CCNA chapter 3 in Resources which describes these two viewpoints. You will need to make both a logical and a physical diagram of the HQ network based on the network shown above with the three routers. This is your network diagrams mentioned in the rubric below.

The company was assigned the following IP address range to use for their HQ networks:

IP: 172.16.1XY.0/22

XY is the first 2 digits of your student ID

4 Format and Presentation You are recommended to present the assignment in a standard report format with the title page that details your name, student-id, unit, course and date/time information. There is no report template to be used in this assignment, so you can make your own template or refer to online resources. However, the report should be well presented with clear headings, titles, subtitles, etc.

5 Submission Format When you have completed the assignment, you are required to submit your assignment in the PDF/DOC format. You can follow the following convention in naming your file:

filename = FirstInitialYourLastName_CSC00240_A3_S3_2018.pdf (i.e. Gsorwar_CSC00240_A3_S3_2018.pdf)

6 Original Work It is a University requirement that a student’s work complies with the Academic Integrity Policy. It is a student’s responsibility to be familiar with the Policy.

Failure to comply with the Policy can have severe consequences in the form of University sanctions. For information on this Policy please refer to Student Academic Integrity policy at the following website:

http://policies.scu.edu.au/view.current.php?id=00141

As part of a University initiative to support the development of academic integrity, assessments should be checked for plagiarism, including through an electronic system, either internally or by a plagiarism checking service (e.g., Turnitin), and be held for future checking and matching purposes.

7 Retain Duplicate Copy Before submitting the assignment, you are advised to retain electronic copies of original work. In the event of any uncertainty regarding the submission of assessment items, you may be requested to reproduce a final copy.

8 School Extension Policy In general, you will NOT be granted extension unless where there are exceptional circumstances. Students wanting an extension must make a request at least 24 hours before the assessment item is due and the request must be received in writing by the unit assessor or designated academic through student service (please visit https://www.scu.edu.au/current-students/student- administration/special-consideration/ for details). Extensions within 24 hours of submission or following the submission deadline will not be granted (unless supported by a doctor’s certificate or

SCHOOL OF BUSINESS AND TOURIMS

CSC00240 – Data communication and Networks S3/2018

where there are exceptional circumstances – this will be at unit assessor’s discretion and will be considered on a case by case basis). Extensions will be for a maximum of 48 hours (longer extensions supported by a doctor’s certificate or alike to be considered on a case by case basis).

A penalty of 5% of the total available grade will accrue for each calendar day (24-hour period) if an assessment item is submitted late without prior extension granted. Therefore, an assessment item worth 20 marks will have 1 mark deducted for every 24-hour period and at the end of 20 days will receive 0 marks.

Students who fail to submit following the guidelines in this Unit Information Guide will be deemed to have not submitted the assessment item and the above penalty will be applied until the specified submission guidelines are followed.

9 Marks and Feedback All assessment materials submitted during the semester will normally be marked and returned within two weeks of the required date of submission (provided that the assessment materials have been submitted by the due date).

Marks will be made available to each student via the MySCU Grade book.
