I need to design the LANs of the case study and design the IPv4 and IPv6 addressing scheme for the case study.
Ammar Zafar S1, 2020 Southern Cross University CSC00240 Data Communications and Networks Case Study: Designing a Small Network This case study will be utilized for both Assessment 2 and Assessment 3. I. SCENARIO AND TASK A small news organization is opening new offices in Sydney Australia. For their office space, they have rented a whole floor in an office building in the Sydney CBD. The rented office space is 40 m long, 35 m wide and 3.2 m high. There will be four departments based at the office space: editorial department, video department, print department and administration department. You are tasked with designing the network for their offices and ensuring internet connectivity to the office. You have to provide a networking plan which keeps cost down and satisfies the organisation’s demands. II. REQUIREMENTS The requirements for the network are: 1) Each department should have a separate wired LAN. This is for security reasons. The departments should still be able to communicate with each other. 2) All four department LANs need to support voice, video and data communication. The all also need access to a printer. 3) 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. 4) There should be ‘fast’ internet access for all the LANS and the WLAN. 5) The network should support both IPv4 and IPv6. 6) There should an application for video chat for the workers as well as email. 7) The network design needs to leave room for 30% expansion both in terms of bandwidth (data rate) and number of users. III. ADDITIONAL INFORMATION 1) The number of hosts for each department are given by Table I. 2) Encryption and security services are provided by another company and you don’t need to worry about them. 3) The network design should reflect the expected usage of the various departments and associated networks. Department Hosts Administration 10 Editorial 30 Video 17 Print 75 TABLE I: Hosts Information Table 1 Ammar Zafar S1, 2020 4) The provision of other applications outside of email and the video chat are the responsibility of another company as well. You only have to worry about these two applications. 5) You are allowed to look at ‘cloud’ solutions. 6) Not everything has been precisely laid out in the problem and requirements. You should and will need to make ‘sensible’ assumptions to design your solutions. 2 Scenario and Task Requirements Additional Information Ammar Zafar S1, 2020 Southern Cross University CSC00240 Data Communications and Networks Assessment 2 Please refer to the case study document for this assessment. I. SUBMISSION DATE The submission date is 17th April, 2020 at 11:00 pm. Late submission will incur a 5% marks penalty per day. Submissions at 11:01 pm on 17th April, 2020 will be considered late. 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. II. PROBLEM For this assessment, you need to complete two main tasks: 1) Design the LANs of the case study. 2) Design the IPv4 and IPv6 addressing scheme for the case study. Let us look at each task in a little more detail: A. LANs’ Design The complete network consists of multiple subnetworks (in this case LANs) each of which has their own design according to usage. As we have learnt (or will learn depending on when you read this) in-class there are many design decisions involved in designing LANs. You need to design each component of the LANs with good justification for your design decisions. Your LAN design should fulfil the requirements laid out in the case study document. You will need to do some research on requirements for some of the functionalities the LANs need to perform and their solutions. For example, as stated in the document all the LANs should support video chats. You may also need to make some reasonable assumptions for your design. You should justify these assumptions. You will also provide costing for your solutions. All costings should be in AUD$. B. IP Subnetting Design We have seen (or will see in-class) that subnetworks and the devices in them need to be addressed. You will need to select a suitable starting address and subnet mask for IPv4 subnetting. The last two digits of your student ID should appear consecutively and in the same order as in your ID, in the starting address. For example, if your ID is 123456, then you can choose an address of the form xxx.x56.xxx.xxx. For the IPv6, please use the starting address: 2001 : DB8 : Θ :: /48 where Θ is the last four digits of your student ID expressed in hexa-decimal. The IP addressing should be provided in the form of tables (one for IPv4, one for IPv6) and contain the information noted down in the case study requirements. The starting addresses should be clearly stated before the beginning of the table. 1 Ammar Zafar S1, 2020 III. SUBMISSION GUIDELINE You will submit both these designs in the form of a report which thoroughly details the reasons for decisions made, as well as the actual decisions made. The report should follow a logical structure and be easy to follow. Jargon-laden and difficult to follow reports will not be looked upon favourably. The total length of the report is 1000 words. In addition you should include a Title Page, Contents Page and a page listing all references. These additional pages are not to be included in this word count. Be sure to number all pages in your report. DO NOT INCLUDE APPENDICIES. The Title Page should have the following information: • Unit code • Unit name • Case Study Title (You can choose any appropriate title you desire.) • Word count • Student name • Student ID An Executive Summary is also required, and should be no more than 200 words. This is in addition to the 1000 word report. All information sources must be appropriately acknowledged and a full bibliography is required. References should follow the IEEE 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 don’t 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. The report should be submitted as a Microsoft Word document through the Turnitin link. The word document should be named named ‘[Your last name] [Your student ID].docx’(quotations marks not included). For example, if I submitted the file it would be named Zafar 123456.docx. IV. ADVICE It is perfectly normal to feel a little nervous when you are doing something for the first time particularly if it is something you will be judged upon. Just look back at your experiences, most probably when you did something for the first time there were some difficulties but after you had put effort in and done it multiple times, it became easier and took less time. The same principle applies here. As this is your first assessment of this kind, you will need time to process and solve it. You will/might difficulties and some tasks might frustrate you. That is absolutely fine. We all get things wrong when we attempt something new. The important thing is to learn from them and correct them. Being wrong and/or making mistakes are not the problem, not putting effort in and/or not learning from mistakes are. You have the required knowledge and reasoning skills to solve this assignment. Use your common sense to guide you. For example, how would you go about buying a PC/MAC? You would probably look at the cost and the technical specifications and find a balance between them while satisfying your requirements. You would also not just look at one PC/MAC, and one retailer. You would most probably look at several options and then make your decision. Similar logic applies for this assessment. 2 https://ieee-dataport.org/sites/default/files/analysis/27/IEEE%20Citation%20Guidelines.pdf Ammar Zafar S1, 2020 You are encouraged to discuss the assessment with your fellow students and teachers. But you must develop your own solution and write your own report. V. MARKING A marking rubric is provided with the assessment. We will mark the assessment holistically. What this means is that overall your solution should make sense and effectively solves the problem. Individual parts of the solution might be good on their own but overall make not work together, hence, making the solution ineffective. We want you to be able to effectively solve the problem. You should not look at each criteria in isolation. Almost all criteria depend on each other. To take an example, you may have the best report presentation but if everything in it is wrong, it does not matter and you will not gain any marks. This reflects the real-world where solutions should work. The layout of the rubric cannot capture this effect but you need to be aware that it is there. Your grade for the assessment will reflect how your overall solution tackles the given problems for this assessment. 3 Submission Date Problem LANs' Design IP Subnetting Design Submission Guideline Advice Marking Ammar Zafar S1, 2020 Southern Cross University CSC00240 Data Communications and Networks Case Study: Designing a Small Network This case study will be utilized for both Assessment 2 and Assessment 3.
