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.

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).

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 explana 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.

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? Don't 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 unit's 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].
