The Scenario for Network Design Assessment Tasks

Your company in Australia specialises in designing networks for local and international clients. Your company has signed a contract with NTN private nursing school located in Sydney, Australia to design their network.

The main campus of NTN is located in Sydney and the satellite campuses are located in Darwin and Cairns. NTN has made agreements with three private hospitals in Sydney, Darwin and Cairns to provide the internship and training to the students of the nursing school. All three private hospitals have Wi-Fi access points that can provide a minimum of 100Mbps data rate to a user. The 2-storey buildings of main and satellite campuses are less than 200m away from the corresponding private hospitals. Each campus building is approximately 15m wide and 40m long.

Lecture, tutorial and laboratory classes are conducted in the campus in Sydney and they are live-video streamed to the satellite campuses forming a virtual classroom. The instructors and the students in the satellite campuses can directly communicate with the lecturer in the Sydney campus when a virtual class is in progress. At any time, there will be at most 200 students in the main campus and a maximum of 100 students in each satellite campus participating in a virtual class. However, these numbers are expected to double within the next couple of years.

NTN also plans to provide a telemedicine and healthcare service to the community in a radius of about 200km from each satellite campus by having a small mobile team of doctors and nursing students. The mobile team in Darwin as well as in Cairns provide consultations and services to the needy patients at their homes. The mobile teams travel around in a specially equipped vehicles called the home-care vehicles, however, unlike in the conventional ambulance services, they do not carry the emergency patients to the hospitals. The mobile team should be able to scan/photograph and send the reports of the patients immediately to the corresponding private hospital and communicate directly with the medical staff there via the network in the home-care vehicle.

Using the top-down network design methodology, you are to design the networks of the main campus, satellite campuses and the home-care vehicles.You are allowed to make assumptions in relation to business and technical goals if they are really required for undertaking your network design. Each step of your network design should clearly explain and justify how you satisfy the business and technical goals.
