Question

Design a network using the 10.20.0.0/16 network address for all computers and devices. The public Internet address is 140.1.1.1. Student-accessed computers should be on a separate network from the staff-accessed computers. The network should use physical cable (not wireless), but provide wireless access in the areas listed in the table below.

Define the subnet (based on: rooms, floor, department, or other criteria).

For each subnet, explain which devices/groups/users/rooms will be on this subnet, define the network address, subnet mask, and available IP addresses to be used by computers or devices.

Network Design:

1. Define the topology that will be used.

2. Select the appropriate network media to use.

3. Select the appropriate network connecting devices to use.

4. List of additional servers, network devices, or network services needed to implement the network.

5. Justifications for your network design (number 1 – 4 above)

Explanation / Answer

Star Topology will be used. As, In star topology all nodes are individually connected to a central connection point, like a hub or a switch. A star takes more cable than e.g. a bus, but the benefit is that if a cable fails, only one node will be brought down. Fiber Optic cable is a best medium to use. As,cable containing one or more optical fibers that are used to carry light. The optical fiber elements are typically individually coated with plastic layers and contained in a protective tube suitable for the environment where the cable will be deployed. for example long distance telecommunication, or providing a high-speed data connection between different parts of a building. Bridge is appropriate network connecting device will use. As, Operates in both the PHYSICAL and the data link layer.• PHYSICAL layer device, it regenerates the signal it receives.A data link layer device, the bridge can check the PHYSICAL/MAC addresses (source and destination) contained in the frame.A bridge has a table used in filtering decisions.It can check the destination address of a frame and decide if the frame should be forwarded or dropped.If the frame is to be forwarded, the decision must specify the port.A bridge has a table that maps address to ports.Limit or filter traffic keeping local traffic local yet allow connectivity to other parts (segments). bridge connecting two LANsA bridge does not change the physical (MAC) addresses in a frame. Hub networking device and client server model needed to implement the network.
