CSC00240-Data communication and Networks

Problem Context 

A private biomedical software development company has three branches spread over the Gold Coast region. The company’s local area network (LAN) is captured in the topology below:  

Head Quarter network has XYZ network devices including all computers, 10 printers, 3 servers, 1 router, 5 switches and other network devices. Branch A, B and C subsequently has XY, XZ and ZY network devices including 2 servers, 1 router, 2 switches in each branch. 

where XYZ are the last 3 digits of your student ID. If any of these three digits is Zero (0), replace them with the next non-zero number in your ID to estimate the size of each branch network. 

Recently, the company has been assigned with a new space of IP addressing and the whole network has to be re-addressed.

Task

There are two ways of presenting a network, the logical view and the physical view. Please read the CCNA chapter 3 in more resources folder which describes these two viewpoints. You will need make a logical diagram for the network shown above with the Four routers. This is your network diagram mentioned in the rubric below. 

You are contracted by the company to help with the IP address planning. The following is the new IP address space:

IPv4 network: 191.2.XY.0

IPv6 network: 2011:1245:ADBC: YX00::/56

See above for explanation of XY. 

• An IPv4 address plan for the LAN

• An IPv6 address plan for the LAN 

You are expected to provide an optimum address allocation solution with the following details:

1. IP address requirement for each sub-network

2. IP address allocation plan for each network/sub-network including network address, subnet mask, broadcast address, default gateway address and valid host address range.

3. IP address allocation plan for key network device and interfaces e.g., servers, printers, router interfaces, etc.
