CSC00240 Assignment 3 S3/2020 CSC00240 – Data Communications and Networks Assignment 3 Network Design for a Modern Software development company Due Date: 1st February 2021 11:00 PM Due Date: 40 % of total unit marks Objectives: By completing this assignment, students will be demonstrating their knowledge and skills learnt from week 1-12 that includes: Logical network design for a typical SME IP address planning Background: A private software company, called Soft.com, is opening its new offices in Brisbane and Gold coast, Australia to sell healthcare products. Their main product is system (software) that provides a variety of health services. The managing director has asked for a "software development company of the future, using the latest technologies with a network which can accommodate the load now and for another five years and leaves room for further expansion". The company's headquarter (HQ) will be located in two adjacent three-story buildings (Buildings A and B) in Brisbane. The distance between the buildings is 20m. The organization has five departments, as given in Table 1: Department Hosts Software Development (100+XY) workstations, (5+Z) printers Production (20+YZ) workstations, (1+Y) printers Marketing (10+X) workstations, (3+X) printers Accounting and Finance (5+Y) workstations, (3+Z) printers Administration (5+X) workstations, (2+Y) printers Table 1: Hosts Information Table Where XYZ are the last three digits of your student ID. If any of these three digits is Zero (0), you replace them with the next non-zero number in your ID to estimate each department's host size. Software Development and Marketing will be in Building A with the other three departments are in Building B. All the workstations, printers, and other devices will be connected through the wired network. There will be support for Bring Your Own Device (BYOD). The server farm (3 or more servers) can be located in Building A. There must be a direct connection between the two buildings. The edge router (the router that will be connected to the Internet and provide internet access to the organization) will be located in Building B. CSC00240 Assignment 3 S3/2020 Future Future aspiration is to change the culture of the workplace. The employees and management particularly want to enable working from home for the software development team. In this regard, it is expected that all software developers will be issued with Laptops/MacBook Pro, which they can take home. The company will also need to increase their resources to support the new online services. The production process will also be updated. The production team will need 50 new computers to control the 3D printers. The administration department will be adding 7 more workstations and 2 printers to handle the extra workload. The company also wants to be more open and allow BYOD, but it does not want to compromise security. The company also needs to connect with a WAN at a branch office (Gold Coast), located approximately 100 km from the HQ of the company. The Gold Coast branch has only two departments: software development (25 hosts) and marketing (6 hosts). They need to be linked to the software development company's HQ network. Important objectives of the Network: The main objectives for the proposed solution are: • A modern network for the company • More accessibility without compromising on security • Support for online services • To ensure that this company has video conferencing between the main office and its branch. The network is proposed to achieve the above objectives considering the company's following business and technical goals. Business goals: • Improved communications, wireless, videoconferencing, etc. • Spare no expense, • Protect company information, • The company of the future will have at least a 30% increase in staff in two years, • Be excellent in technology. Technical goals: • The current network, computer rooms are to be upgraded to a modern network (campus design) to meet developers and employee's needs, • Scalability – remember they want to expand for the next five years, • Availability – Wireless network access is available in all employees as well as some outdoor areas for software developers and employees, • Employees have access to company resources from both company and home (different servers), • Performance – network performance must be high, • Reliability – no single point of failure, • Security – protection of company information and other IT assets, You are required to design a recommended network for the Company's HQ (main branch) LAN based on the current and future user network requirements and the WAN link to the Branch office. CSC00240 Assignment 3 S3/2020 What you need to do You are required to design the network you would recommend. Remember, the goal of building a new network is that it will support the company's needs for the next five years. Your recommendations are to be submitted as a formal report containing your analysis of the present situation and your recommended network solution. You are free to make any further assumptions you wish. In your report, you are required to: i. Analyse user network requirements. ii. Suggest a type of network architecture that is suitable for the organisation. You will need to identify all the media (circuits), network hardware necessary to build the network(s) you are proposing and to justify your choice, i.e., you will need to explain the function of the hardware and network choice in your solution and to justify your choice by value for Money, Quality of Service (QoS), security, etc. iii. Each department should have a separate wired LAN. This is for security reasons. The departments should still be able to communicate with each other. iv. All department LANs need to support voice, video, and data communication. They all also need access to printer(s). v. There also needs to be wireless access throughout the floor for all the workers to connect their own devices. The wireless LAN should be secured, so no person from outside the organization uses it. vi. Explain IP address plan for the proposed network. vii. Explain logical network design with diagram(s) for the proposed network. viii. Draw physical network(s) diagram that shows how you connect the hardware you have chosen in (ii). ix. Designing/selecting a WAN connection to provide fast, reliable but inexpensive and secure Internet access. x. There should include an application for video chat for the workers as well as email. xi. The network design needs to leave room for 30% expansion both in terms of bandwidth (data rate) and the number of users. The company was assigned the following IP address range to use for their networks: IP: 1XZ.1Z.1XY.0/20 XYZ is the last two digits of your student ID. You are expected to provide an optimum address allocation solution with the following details: IP address required for each sub-network. IP address allocation plan for each network/sub-network, including network address, subnet mask, broadcast address, default gateway address, and valid host address range. IP address allocation plan for key network devices and interfaces, e.g., servers, printers, router interfaces, etc. As part of your report, you are required to write an executive summary explaining why your design meets the business and technical goals. Presentation and referencing are important. Remember that it is a company, and access to the Internet will need to be controlled and some sites blocked. Your report must include explanations justifying the design decisions you have made. To help with these assumptions, the following information is available: IT Platform: Windows Server 2019 Switches/routers (Cisco/Huawei) CSC00240 Assignment 3 S3/2020 Encryption and security services are provided by another company, and you do not need to worry about them. The provision of other applications outside of email and video chat is the responsibility of another company. You only have to worry about these two applications. As the HQ needs to be connected to the branch office, you will need to show how the HQ is connected to the branch office. 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 networks. These are your network diagrams mentioned in the rubric below. WAN Internet Connection Everyone at the office requires Internet access. The choice of the Internet connection must keep in mind the requirements of each of the LANs and any other uses of the Internet. You can assume that Network Address Translation (NAT) comes pre-configured in the router that comes with the Internet connection you select. You can also assume that Public IPv4 addresses come with an Internet connection. Application Design You need to select the applications to fulfill the requirements for email and video conferencing. You will also need to select the model(s) of how the applications are utilized and how they fit in the overall network design.

However, the report should be well presented in a standard report format. Due to the system setting constraint, the report length was set with 2000-3000 words in the unit UIG. You are advised that there is no formal word limit for the report. However, a good report is expected to be somewhere in the vicinity of 2,000 - 3,000 words from Introduction to Conclusion. Note that this is a very rough estimate, and there will be no penalties imposed based on the number of words (no real ceiling if the content is precise and relevant!) Submission format There are two links provided for assessment 2 submission: 1) Turnitin link, 2) Assignment Submission link. You have to submit the same report to both links. If they are not the same or you do not submit in both links, you automatically receive a Fail. The Turnitin submission will be used to check for academic misconduct, while the Assignment Submission link will be used for marking purposes. Please make sure you review the report generated by the Turnitin system and make changes (if necessary!) to minimise the issues of improper citation or potential plagiarism. When you have completed the assignment, you are required to submit your assignment in the DOC format. You can follow the following convention in naming your file: filename = FirstInitialYourLastName_CSC00240_A3_S3_2020.doc (i.e. Gsorwar_CSC00240_A3_S3_2020.doc) 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 the 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 may 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. Retain duplicate copy Before submitting the assignment, you are advised to retain electronic copies of the original work. In the event of any uncertainty regarding the submission of assessment items, you may be requested to reproduce a final copy. CSC00240 Assignment 3 S3/2020 School extension policy In general, you will NOT be granted an 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/studentadministration/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 where there are exceptional circumstances – this will be at the 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 a 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. Please make sure that you submit your assessment well ahead of the deadline as issues such as internet connectivity may cause last-minute hiccups. No extensions will be provided unless applied through special consideration with proof of genuine reason for delay attached. 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.
