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 to design the network for OZ Dispatch, a home delivery service located in Parramatta, NSW, Australia.

In the Parramatta office of OZ Dispatch, there are the managing director who is also the owner, a data analyst, a sales & marketing executive and an accountant. The data analyst will need to deal with large volumes of customer, sales and product information.

Customers should be able to place their delivery orders containing one or more items and pay either using the web interface of OZ Dispatch or the phone. The orders are collated by the system and separate purchase orders for each item in the collated list are created and placed with the supply companies. The delivery staff of OZ Dispatch then collect the ordered items from the suppliers and bring them to the 20 collection and distribution centres (CDCs) of OZ Dispatch that are located at various places in NSW. When the order of a customer is ready, a delivery staff member currently at the closest CDC is prompted by the system. Then, that delivery staff member selects the items of the customer’s order and delivers them to the customer.

Except the 20 delivery staff and the manager, there are no other staff working at any distribution centre. Each delivery staff member and the manager should be provided with a smartphone containing the necessary apps. Each distribution centre should have Wi-Fi and an Internet connection.

All servers should be located in the Parramatta office and the managing director does not support a cloud-based solution. For the protection of customer and business information, a highly secure network should be designed.

Using the top-down network design methodology, you are to design the networks of the Parramatta office and the CDCs. 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.
