In this project, you will design a network for a middle$-$size company. Connection to the internet will

be provided by an ISP. The company is occupying $3$ floors in a building. Floor$1$ contains the

administration offices of the company.

Here are the requirements for floor$1$:

$$ The network in this building should service at least $10$ employees.

$$ Each employee should have at least one wired and $2$ wireless connections.

$$ This floor is the administration part of the company, and clients will not be accessing it$.$

However, the company would like to make $10$ additional wireless connections available for

visitors that might be present in this floor.

$$ There are two printers in this floor.

$$ This floor also contains the servers of the company as well as the router receiving the

connection from the ISP and the main switch that will service the switches of the three

floors.

Floor$2$ and floor$3$ are the main service floors of the company.

The following are the requirements for floor$2$:

$$ The network in this floor should service $15$ employees. Each employee should have at least

one wired and $2$ wireless connections.

$$ This floor will service many clients, and the company wants to ensure that they have a

wireless connection. The connection should support as many clients as employees at any

time.

$$ The floor contains one printer.

The following are the requirements for floor$3$:

$$ The network in this floor should service $10$ employees. Each employee should have at least

one wired and $2$ wireless connections.

$$ As in the case of floor$2$ in this building, this floor will service many clients, and the

company wants to ensure that they have a wireless connection. The connection should

support as many clients as employees at any time.

$$ The floor contains two printers.

The following are the general requirements for the network:

$$ The company requires the networks for the three different floors to be different subnets. The

connection between these $3$ subnets is wired.

$$ Each floor requires only one wireless access point.

$$ Wireless devices could be smartphones, tablets or laptops.

$$ The company would like to have its own email domain and service.

$$ The company would like the addressing of the devices to be dynamic.

$$ The company would like to have its website hosted on a server that it owns.

In order to carry out this design project, you are required to answer the following questions:

$$ What is the IP address class required to meet all the above$-$mentioned requirements? Justify

your decision.

$$ Suggest an address from the class you suggested previously along with a mask. This would

be the address the company is getting from the ISP.

$$ What are the masks required to meet the subnetting requirements of the network and each

subnetwork for each floor? Justify your decisions.

$$ What are the specifications of the switches in this network? The network requires $4$

switches: one main switch and one switch per floor. Justify your decisions.

$$ What are the specifications of the wireless access points in each floor? Justify your

decisions.

$$ What are the servers that the company must have?

$$ Draw a network diagram of your design, including the router, the wired connections, the

switches, the wireless access points and the servers.

$$ Describe how you would protect the network from intrusion attacks.
