Part A (85 marks)

About FunElectronics: • FunElectronics (FE) has two offices, one in Toowoomba and one in Brisbane. • There are four teams of employees: o Design – 100 employees, working in Toowoomba office o Finance – 40 employees, working in Toowoomba office o Management – 10 employees, working in Brisbane office o Sales – 200 employees, working in Brisbane office • All 4 teams will be accessing 20 servers located in the Brisbane office. • No wireless connection is required in both offices. • For simplicity, consider the gateways of the two offices are linked directly without involving any extra intermediate / external device. • Internet connection is not expected for both offices for this proposal. However, the FE network will eventually connect to the Internet. Basic requirements of your design: • Design an address scheme for FE: o Consider the use of private and global IPv4 addresses.

CSC8510 Assessment 3o State the use of which address(es) you have to pay for. o List the (range of) addresses used by the four teams, the servers and the gateway(s) o Keep in mind that the network will eventually connect to the Internet. • Use static routes between the gateways. • State how PCs in Toowoomba can connect to servers in Brisbane. o List the devices a packet traverses from Toowoomba to a server in Brisbane. o List the source and destination IP addresses, Mac addresses of a packet travelling from a PC in Toowoomba office to a server in Brisbane office and back to the source PC.

CSC8510 Assessment 3 ▪ Assume that the packet can travel directly between the gateways in Toowoomba and Brisbane without going through any intermediate device. ▪ Assign a MAC address to the source PC, the destination server, and each of the intermediate device traversed. ▪ List the source and destination IP addresses, source and destination Mac addresses when a packet travels from a PC in Toowoomba to a server in Brisbane and back to the source PC.

CSC8510 Assessment 3 • Your design (PDF file) submitted should be less than 10 pages (Font size at least 10). • Provide a report on your design less than 10 pages, in pdf format and including at least: o The requirements of the network o Details of your design for the FE network o List your design considerations, your reasonings and your conclusions and how your design can match each of the requirements ▪ What are the alternatives?

CSC8510 Assessment 3▪ Which one is your preferred choice and why? ▪ Example: o router 1 G0/0 using IPv4 20.10.10.1/30 connects to router 2 G0/0 using IPv4 20.10.10.2/30 o IPv4 20.10.10.1 and 20.10.10.2 are globally routable (ITN Module11 slide 13) o /30 reduce the IP address wastage as it allows 2 hosts only. (ITN Module11 slide 25) • Provide a Packet Tracer file to demonstrate your design: o You must use Packet Tracer version 8.0.1. Other versions may not be compatible, and we may not be able to open your file(s). o Use 2 PCs to represent a network / subnet etc. o Connect PCs to switch(es) using UTP cables o Connect switch(es) to router(s) using UTP cables o Connect gateway to gateway (such as routers between Toowoomba and Brisbane) using Serial (WAN) cables Submit your work as PartA.pdf e.g. U123456PartA.pdf and PartA.pkt e.g. U123456PartA.pkt
