NIT1104: Computer Networks ; Design an Ethernet LAN for a Given Floor

Design and configure the LAN to meet the design requirements.

The design document should include;

1.A network diagram of the LAN with detailed information to show the functionality of each network device in the diagram.

2.A site map that show the deployment location of each network device in the site

3.A detailed list of the network inventories including;

The network devices with detailed specification and amount of each type
Network cables and estimated amount of each cable type in meters,
Any other accessories such as connectors and tools.

4.An IP network addressing plan that specifies;

For each subnet, the network address, broadcast address, valid host address range that will be assigned to the PCs. Note that you need to spare 10% of the total addresses of each subnet for future development.
The IP address of each router interface.
Any unused address space

. The configuration document should include;

1.Detailed configuration commands for all routers and switches.

2.A Packet Tracer file implementing a simplified solution of the LAN.

On the Packet Tracer, include only 2 computers for each sub-network

3.Screenshots from the Packet Tracer showing that you can connect between sub-networks and the gateway (using ping to verify the connectivity).

Answer:

1. Network Diagram of the local area network

2. Site Map shows the deployment location

3. Detailed network inventory list
