Project Overview

This documentation is a proposal for LAN network design for an IT college that has recently leased a building in the Melbourne city for offering IT courses. The IT College which contains two buildings named building 1 and building 2. The distance between the buildings is 500 meters. The estimated number of users in the college is about 400, 300 users in the building one while 100 users in building 2.Each building has a lobby where Wi-Fi access points are fixed to provide wireless internet to the students. The IT College requires highly secured network to be implemented and used in the school. Building one is divided into four computers labs while building two is divided into three labs. Each computer lab is expected to a have a server for data storage and IP phones for making calls [1].

This project aims at designing a network for the IT a college that is located in Melbourne city. The college is expecting a well-designed network that is highly secured and scalable that will be used by students in their studies. The college that has two buildings and each building having a lobby provided with secured wireless access point. 35 computers working stations will be set up in each computers lab. All of the 35 computers will connected to the internet .Servers in each computer will highly secured and backup to enhance high security of data [2]. The aim of the project is to come up with scalable network design that will be implemented in the IT College.

The type of component that are used in any given network depend on the organization requirement and the type of topology to be used in any given network [3]. Type of data that will be used in the network will also determine the network plan to be used. Datatype used in this network will include reports, internet activities including websites. This makes the network to be implemented in the college to have the following devices [4].

• Servers –This will be used for data storage.
• Computers-will be used as end devices in the network.
• Ethernet cables-for connection of network components together e,g switch and computers.
• Fiber cables- used in connecting the server and switches.

Others include:-Other devices that were implemented in the network in network include:

• Switches

Devices such UPS will be used to control the shutting down process of electrical components when there is power loss [5].

 The following tables show the device that were used in the network.

Total cost					$60000o

The cost estimated for implementation was about & 600 000.

Different type operating system will run in the network .Both windows 7 and 8 will be used in the network. Windows 8 will be used in client computers while windows 7 will run from the server side. The server side will serve information to other computers [5]. Heavy applications will accessed from the server side. The website of the college will run from the server accessed by clients over the internet. Other applications that are important to the institution will also run from the server side. Other application like Microsoft word a will be installed in the client side.

Types of Devices Used in the Network

Computers in the labs will have one or more account. Users of the network will have limited access to network than the admins.The admin will have access to all areas with the network while the users will only have access to few areas in then network. The network is expected to serve around 400 users in the college [6]. Wi-Fi network will be secured to prevent unauthorized users from accessing the network.

The network will be secured in the following ways. Anti-viruses will be installed in lab computers to prevent malicious soft wares from accessing causing arm or fetching information from the network. Firewalls will be installed at various sections of the of the network especially server areas in order to prevent viruses from causing harm to users in the network or collecting information which is not allowed from the network [6]. Each computer will have a password .This means no door will be left open for unauthorized users. On the other hand Wi-Fi wireless networks will have strong and encrypted passwords to prevent attackers from accessing it. AES algorithm will be used for password encryption in this category since is more secure and hard to crack.

The network will have a data backup plan where all servers will be connected to a secondary server that will be in cloud. The data backup plan will be stored will use windows to automatically update data in the cloud [7]. Data will automatically be updated in the cloudy and the end of every day. Other recovery plans in the operating system will be activated to recover data in case there is any data loss.

The following shows how the network will be designed in the IT College

The above is the design of the IT college network for the two building. The sub-networks from the two building are linked together through a router. Each building has its own main switch. The main switch then connects to 48 port switches that are found in each room. Since building 1 has four rooms, each room will have its own switch. The switch in each room will be connected to 35 computers and IP phones. Server in each room will also be connected to the switch so that computers can read data from it. IP phones are used for calling. The wireless access point and router is connected to the main switch of the of the building to serve users with wireless network. In building two which is 500 meters away from building 2 and has three rooms the case is the same. In building 1 the main switch connects to the three switches found in the in each room. Each switch in each room connects 35 computers, IP phones and the server together. The above method of designing the network will make it faster since  star network topology will be implemented .Star topology does not cause  collision of packets in the network this makes it a suitable topology  to be implemented in any network.

Different devices were configured in different ways. The IP addresses that were used in the network were private [8]. Computers were allocated with IP addresses from 172.161.1.1 to 172.161.1.125. Other computers were allocated with IP addresses from 192.168. 1.1 to 192.168.1.125.

The following shows how servers were configured from computer lab 1 to lab 7.

Device	interface	IP address	Subnet mask	Default Gateway	Switch port
Router	Ga0/0	192.168.1.1	255.255.255.0	n/a	n/a
	S0/0/0	10.1.1.2	255.255.255.0	n/a	ga/0
Server  1	Fa0/1	192.168.1.2	255.255.255.0	n/a	ga0
Server 2	Fa00/2	192.168.1.3	255.255.255.0	192.168.1.1	Fa3
Server 3	Fa0 4	192.168.1.4	255.255.255.0	192.167.1.1	ga 03
Server4	fao	192.168.1.5	255.255.255.0
Server 5	fao	192.168.1.6	255.255.255.0
Server 6	fao	192.168.1.7	255.255.255.0
Server 7	fao	192.168.1.8	255.255.255.0
