PROBLEM
For this assessment, you need to complete two main tasks:
Part 1) Design the LANs of the case study.
Part 2) Design the IPv4 and IPv6 addressing scheme for the case study. Let us look at each task in a little more detail:
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$.
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.
Case Study: Designing a Small Network
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.
