Submission format: This assignment has two parts. Part 1 is writing a technical report (worth 60%) and Part 2 consists of network design, CORE implementation and a video presentation (worth 40%). Before the due date, a soft copy of your technical report (a PDF file) with the standard assignment format, CORE network design file (imn file) and a 10-minute (max) video that shows the operation of the network design must be submitted to Moodle via the submission link provided under Assessments section on the Moodle as individual files. Zero marks will be awarded for part 2 of the assignment if the video is not provided. You can use any freely available PDF converter. Your report will be checked using Turnitin for Plagiarism. When you submit the assignment in Moodle, please make sure to submit your work properly. No submissions should be left in the draft mode. Before the expiry of the deadline, make sure to hit the Submit button to complete your submission. If the submission is in draft mode, your submission will NOT be considered for marking. Late submissions: By submitting a special consideration form Without an approved special consideration request, you lose 10% of your mark per day that you submit late. Plagiarism: This is an individual assignment. Group work is not allowed. It is an academic requirement that your submitted work be original. Zero marks will be awarded for the whole submission if there is any evidence of copying, collaboration, pasting from websites, or copying from textbooks. When you are asked to use Internet resources to answer a question, this does not mean copying and pasting text from websites. Write answers in your own words such that your understanding of the answer is evident. Interview: Your tutors may conduct an interview in special circumstances (Collusion, Plagiarism etc.) to assess your work. If you cannot explain your work or what you have written in your report, we need to report you to the academic Integrity committee for further action, and your marks will be either reduced or given 0. If you need extra help: This assignment is an independent learning and assessment exercise. You may utilise the Ed Discussion Forum to ask questions and obtain clarification. Additionally, you can join any of the scheduled consultation sessions to seek support, however, you may not share any details or designs in your implementation with other students, nor may you show working to the teaching team prior to the submission. This is an assessment task: tutors and lecturers are not permitted to help you to check errors in your assignment work (you are expected to check the correctness or troubleshoot your CORE network design), but can help with more general queries, such as queries related to syntax, concepts and troubleshooting tips. You may make use of online references with appropriate citation in accordance with academic integrity policies, however, your work must be your own. 2022, Faculty of IT, Monash University Part 1 Report (60%): The Technical Report should look professional (assume this report will be submitted to your manager), which means you need to pay attention to spelling, punctuation, grammar. It is important that your report has a clear structure. Write a report with a maximum of 8 pages, with a font size of at least 12pt with 2cm margins. The page limit doesnt include images, tables, references etc. Any text beyond the page limit will not be assessed. You may use a FIT standard report format. Please note NO handwritten work or hand drawn diagrams will be accepted for your submission. Note: Later part of the report should include a few details related to part 2 of the assignment (this section will not be included in the page count). You can find great tips on how to prepare a report on Monashs web pages. Here is the link to get started: Language and Learning and Online website: https://www.monash.edu/learnhq Software tools for drawing sitemaps: any drawing tool should work, for example LucidChart, Visio, online tools or even presentation tools such as PowerPoint, Keynote or Google Slides. Scans of hand-drawn maps are acceptable if they are neat and readable. Part 2 CORE network design and a 10 minutes (max) video (40%): You are required to design the network using CORE according to the given specifications. Then a video of maximum 10 minutes long (any video longer than 10 minutes will not be assessed. Its okay to have a video shorter than 10 minutes. i.e., 5 or 6 mins). 2022, Faculty of IT, Monash University Part 1 - An Enterprise Network Design (60%) A Request for Proposal (RFP) to Design Wired LANs, Wireless LANs, Distribution network / support Backbone Wide Area Network (WAN) 1.1 Description Objective A public financing company requires its office buildings to be connected over a wired LAN, Wireless LAN (WLAN), and WAN connections (building to building). You have been asked to respond to prepare an RFP for this scenario. Scope of the Work The company has 150 employees and expects to expand their business by hiring more employees. To match with the requirements, they are acquiring two new 4 storey buildings located opposite the main road to the existing building. Due to the expansions, the company is expecting to hire 260 new employees. Each new employee will be provided with an office space or a cubicle with a multimedia desktop having a wired network LAN connection. (See Figure 1 for Building-A, and Figure 2 for Building-B). Two newly acquired buildings will be used to accommodate all the new staff members as follows: (i) Building A: 160 new staff members (ii) Building B: 100 new staff members. For each building, new staff will be equally distributed among each floor. The new buildings have NOT been wired for network connections. Each floor has a wiring closet where necessary horizontal and vertical structured cabling can be installed. Each wiring closet is in the Lift and Service wells area as shown in the figure 1 & figure 2. The service wells also have vertical risers where fiber optic cables can run through floor to floor to a dedicated server room on the ground floor. Both the new buildings require horizontal and vertical cabling. The networks in the two new buildings should be connected to the main existing building across the road via a distribution network. The width of the road is 100 meters. 2022, Faculty of IT, Monash University The networks that will be implemented must provide both wired and wireless connectivity for the staff members. Each staff member will receive a staff PC and they also can use their own device too. A high-resolution video conferencing software (VoIP), business applications and other usual packages such as web, email and regular office software will be installed in both staff and personal devices. Therefore, anticipated average network traffic generated by each active user is estimated to be around 15-20 Mbps. The Wired LAN infrastructure needs to be designed to support the maximum peak traffic. In addition to the wired traffic, wireless traffic also should be accounted for. Wireless traffic can be considered as 20% of wired traffic. Wireless Access Points (APs) should be connected to the wired infrastructure. Capacity of the network in the existing building (which is located across the road) will also be improved to accommodate the increased traffic owing to the services that will be given to the new staff members. You are NOT required to consider improvement plans for the existing network. Employees are expected to access the main office network and its resources frequently. So, from the business perspective, it is important that the WAN connectivity is maintained with a higher reliability all the time. Loss of connectivity is not an option here. Your proposed solution must be realistic and design tradeoffs should be considered (i.e metrics such as implementation cost). 2022, Faculty of IT, Monash University 1.2 Requirements Submissions for this assignment should be in the form of a technical report with explanatory figures and other requirements for reporting. The assignment specifications are in the form of a request for proposal (RFP) to potential suppliers. An RFP is a solicitation often made through a bidding process by any company interested in the design and procurement of installation contract services. This assignment provides an opportunity for you to work individually and apply Data Communications and Computer Networking concepts to a practical network design. You are required to design the network, provide recommendations based on the RFP requirements and present your solutions in a formal report. In the RFP, the company expects you to give them enough arguments in support of your network design to convince them, with respect to benefits of the proposed network and new technologies you have proposed. You may need to do small research to find differences between technologies. Give detailed explanation of the proposed technologies that would be integrated in the network design. You must include the following information in response to the RFP: a) Executive Summary: b) Introduction: c) Project Requirements: A requirement brief is usually a detailed list of the required tasks to be completed and proposed equipment derived from the Objectives and Scope of Work section of the RFP. d) LAN, WLAN, Distribution / Backbone, and WAN Design, Assumptions, and Justifications: i. Explain LAN, WLAN, Backbone, and WAN design logic including the choices of equipment (e.g., switches, routers, APs etc.) and structured cabling. You must propose specific devices from a particular vendor (i.e. CISCO, Juniper ,etc). Explain methods used to estimate the required performance of devices and links (i.e. max network traffic per floor, per building etc.). Report all the assumptions made in your network design. ii. Justify switch and wireless AP locations, horizontal and vertical cable paths and lengths between the floors. Explain the routers, switches, and APs functional specifications. Assume the floor to ceiling height as 3 meters approximately including the false ceiling. iii. Propose an IPv4 address plan for the new buildings with proper subnetting and minimal unused addresses. e) Recommendations and Justification: A summary of your recommendations with a statement of justification. f) Conclusion Note: List of equipment, their specifications, technical data, and device related cabling specifications etc. should be included in the Appendix. 2022, Faculty of IT, Monash University The technical report should contain the following important diagrams to support your proposal: a) A conceptual high-level diagram showing the complete network design including LAN, WLAN, Backbone, and WAN connectivity to the main office. b) Typical floor plans (only one floor would be sufficient for each new building) showing computer desktop layout, network topology, WLAN AP, and structured cabling. c) Backbone connection diagrams (using schematic diagrams of cross-section of a building showing switches, routers, and servers etc.). d) WAN connectivity for the two new buildings connecting with the head office (main) building. Reporting Instructions Writing reports is an essential skill of any IT career. You are expected to deliver reports that are accurate and factual, that provide evidence for your findings, and must look professional. Before you start Before starting to write, think about your audience, i.e., who is reading the report? Dont write for your tutors. Write for your customer (Transport Company). Sources and referencing Any claims or recommendations that you make should be substantiated with supporting references. That means that you cannot just claim that A is better than B, you must argue why that is the case and point to external sources that can serve as evidence. You can use the units recommended textbooks and other standard literature as sources, but you will also need to use additional documentation to find technical information and commercial details for this report. Whenever you use material from an external source, make sure to include them in your list of references and cite them properly in your document. You also need to assess the quality and reliability of any source. Always use credible sources such as, journal and peer reviewed conference papers, books, technical reports and avoid less credible sources such as blogs. References should be listed correctly. You may lose marks for poor referencing. You should use the APA referencing style, which is explained in detail here: [https://guides.lib.monash.edu/citing-referencing/apa7th]. 2022, Faculty of IT, Monash University Part 2 A network design implemented using CORE and a video that explains the operation of the network (40%) 2.1 Providing IP plans and designing the network using CORE. Here you are required to implement a network using CORE with the following specifications.
