ACKNOWLEDGEMENT

We would like to express our deep gratitude to all those who gave us the possibility to

complete this assignment. We are deeply indebted to our teacher Mr. Udesh Amarasinghe

whose help, stimulating suggestions and encouragement helped us in the completion of this

assignment

We would like to thank Asia Pacific Institute for Information Technology (APIIT) for

providing us with library and computer laboratory facilities as well as the other necessary

facilities which was required for the completion of this assignment.

Especially, we would like to give our special thanks to our parents whose patient love and

support enabled us to complete this work.

1.0 Introduction

The networking project scenario requires us to create a network for the APIIT Law School,

which will consist of four buildings each separated by 10 meters. The CEO of APIIT Lanka

wishes to offer the law degree in newly purchased four buildings which are situated closer to

each other. All four buildings which will make up the entire Law School are 250 meters away

from the current APIIT building.

The CEO wants the new APIIT Law School to function independently, where it would have

all departments such as Academic, Accounts, HR, IT, Business within the building. The CEO

also requires the new APIIT Law Schools IT system to have a relationship with the current

system of APIIT Lanka. Therefore a secure network should be established in order for the

Law School to connect with the main building, this network should provide security of

confidential data, accessibility of resources, e-mail facilities, back-up plans, etc. The network

also should be able to have high speed access to the internet.

As the network consultants of this proposal, we have prepared a network plan to fulfill the

requirements mentioned.

2.0 Perceived Assumptions

y For this network plan to APIIT Law School we dont deem the expenses.

3.0 Perceived Limitations

y PSTN network is not established on our Network Plan to APIIT campus.

4.0 Network Plan

4.1Main Plan

Figure 1: Main Network Plan

Internet Connectivity

In Sri Lanka there are three main internet connections available to Local Area Network.

y Leased linesy WI-MAXy ADSL

After comparing the security options,ease of management and the accuracy of data in those

three connections we decided to use leased line connection. Leased line connections give a

constant bandwidth connection. We decided to take one leased line from Dialog and two

leased lines from Sri Lanka Telecom. The reasons to take the LAN connection from different

dealers are to keep the internet connection in the APIIT law school constant even though if

one of those dealers connections get corrupted.


9/40

In order to provide and better service to the users without and bandwidth dilemma we

decided to use 512 Mbps. After integrating the those three lines with a load balancer it is used

for servers and for the users to browse and to connect to the internet.

Firewalls

Bradley Mitchell (n. d) stated that:

A network firewall protects a computer network from unauthorized access. Network firewalls

may be hardware devices, software programs, or a combination of the two. Network firewalls

guard an internal computer network against malicious access from the outside. Firewalls mayalso be configured to limit access to the outside from internal users.

In this network proposal we have used dual-firewall architecture to protect the internal

network more effectively than single-firewall architecture. The dual-firewall architecture has

two firewalls, the external firewall and internal firewall. The external firewall is used to.

Network traffic is permitted into the DMZ (Demilitarized Zone) from both the internal andexternal network, but however no traffic from the external network can directly access the

internal network.

So therefore the external firewall will be configured to grant access to and from the DMZ and

external network, while the internal firewall allows access to and from the DMZ and internal

network. This will increase security of the internal network as there is no direct access from

the external networks.

E-mail Server

The e-mail server is used by APIIT to provide e-mail facilities to staff and students. So sincethis server would be accessed by students and lectures when they are not within APIIT

premises, the e-mail server is placed in the DMZ area. Placing it in the DMZ will allow usersfrom external networks like students and lecturers to access their e-mails.

Backup Server

This is the way to keep the essential files into one single compressed encrypted file so that

they can be used in an tragedy. If the system faced up with a corruption those data can be

restored and get the system in to normal condition easily.

The backup server is connected layer 3 backbone switch which is updated every time when

there is a change in the system. The backbone switch is protected by an inner firewall so thatin any situation backup server is truly protected


10/40

DHCP/ DNS server

DHCP stands for Dynamic Host Configuration Protocol and is used to assign IP addresses tohosts in the network automatically. This also can be done manually but as that is a time

taking and inefficient that DHCP is taken as the best method to assign Ip addresses to hosts. It

gives IP addresses for number of hosts at a given time. But if the user doesnt use the IP

address for specific time the DHCP server has the ability to assign that IP address to anotherhost. Every time when there is a change in the DHCP is should update the DNS server.

DNS stands for Domain Name Service and this used to store large number of IP addresses

and also used to cover human readable names of hosts to IP addresses. DHCP and DNS

severs are protected by an inner firewall so that in any situation DHCP and DNS severs are

truly protected

In our network plan to APIIT Law School we assigned many wireless access points so rather

than assigning IP address manually to the users every time they log to the WIFI we areplanning to use DHCP so that it can assign IP addresses automatically. Also a DNS server

along with that to store the IP addresses.

(The Computer Technology Documentation Project. n. d)

Print server

When a user requests for a print this should assign the job to vacant printer. This is managing

the printing requests from the clients. So that let the client to user any printer whenever he or

she logs to any computer in those labs. Print server is protected by an inner firewall so that in

any situation print server is truly protected.

Database server

This is the main database for both students and the staff stores their details. This has the

ability to be accessed by any computer. Rather than storing the data in every unconnected

computer this sharing method is more efficient. Database server is protected by an inner

firewall so that in any situation database server is truly protected.


11/40


11

VPN server

We are planning to use a VPN server to link APIIT and 1 st building and also to link the four

building so that data can transfer mainly through the VPN. Another purpose of the VPN

server is to supervise and validate the users who connect in and out through the VPN.

Proxy server

According to our network we will planning to use windows based server called ISA server. In

our network this is mainly use for internet security, packet filtering, user authentication,

cachingstorage devices and act as a firewall.

Web server / Application server (www.apiit.lk)

In our network system this web server will run for the internet applications. Mainly we willuse this server because of the web application of the APIIT law school. Here we use Apache

Linux based software as our web server. Its use because it gets more security and morereliable to the server.

File server

This contains only the storage and authentications of the users. Course materials lectures

files and students files stored in this server. It will be easy to both students and lectures.

yNetwork - Attached Storage

This is a use of file storage device in the network. This NAS will be configured fromthe file server. Its useful to file sharing, sharing printers and media streamer in our

network.

(CBS Interactive 2010)

Learning Management System (LMS)

Learning Management System is used for students teaching support material, studentssupport materials, online registrations, online students chatting for academic purposes,

online classes, online assignment submissions and online questioners in our network. The

LMA software that we are planning to use is Moodle.

This is a main building in the APIIT Law School. It has two floors. Hall the building containswith Layer 2 and Layer 3 network switches. Difference between the Layer 2 and Layer 3

switch is Layer 2 switch is not a manageable switch and Layer 3 switch is a manageable

switch. Also Layer 2 switch is use just for broad casting purposes. Layer 3 switch is nearlysame as routers and inside of that it includes operating systems.

4.2.1 Ground Floor

Floor Plan

According to main network diagram this floor will contains four departments and

receptionist. Departments such as Accounts department, Human resources department,

Information department and Business department.

Network Plan

Figure 2: Building 1 Ground floor

These departments computers, receptionist computer and wireless access point connected

with Layer 2, 24 port switch. From that switch all the cables will connected to the backbone

switch of the 2nd floor server room.

4.3 Building 2

4.3.1 Ground floor

Floor plan

The second building ground floor consists of two counselor rooms, six syndicate rooms and

one Staffordshire office.

Network plan


As seen in the above diagram this floor consists of a few devices such as a wireless device,

computers, patch panel and a Layer 2 switch. The wireless device is a wireless router set with

a secure username and password, so that an outsider will be restricted from logging into the

network. An Access point is set up in the middle of the floor so that any student, lecturer or

employee within APIIT can get better access to the WI-FI connection.

The Layer 2 switch used in the ground floor will have an eight port switch considering the

few number of computers used in this floor. All the computers will be connected to the patch

panel and then to the Layer 2 switch.


16/40


16

4.3.2 First floor

Floor plan

The first floor consists of the library, a study room and four syndicate rooms.

Network plan

Figure 6: Building 2 First floor

In the above network plan of the floor there are three computers, patch panel and a wireless

access point. These devices are connected to a patch panel which in turn is connected using

an eight port Layer 2 switch, common to all other floors in all four buildings. The wireless

access point is once again set in the middle of the floor to give user of the WI-FI connection

better access.


17/40


17

4.3.3 Second floor

Floor plan

The second floor consists of the Cafeteria and Game Zone.

Network plan


As shown in the diagram there is only a wireless access point, a patch panel and a Layer 2

switch used on this on this floor. The WI-FI connection is the main thing that any user in the

second floor make used of.


18/40


18

4.4 Building 3

4.4.1 Ground floor

Floor Plan

Ground floor of this building is going to be used as examination hall which is consists of

small exam halls.

Network Plan

As shown below this floor consists of a wireless access point which is connected to a layer 2

switch and that will be used as the main switch of each floor in this building.


For the ground floor main switch eight port layer 2 switch is used. Wireless connection will

be secured from a password so that the connection will be protected from non APIIT people.Wireless access point is connected to a Patch Panel and it is connecting to the layer 2 switch.

When any device which is connected to the switch went out of order that should be removed

from the switch. When we are doing that there is a high chance of getting the cable or the

switch damaged. So the purposes of the patch panel are to protect the switch and the cable

and to avoid unwanted expenses.


19/40


19

4.4.2 First Floor

Floor Plan

This floor is going to be use to have class rooms. There will be 13 class rooms in this floor.

Every class room will have an individual computer for the lecturer.

Network Plan

As shown in the above diagram, this floor consists of 13 computers, wireless access point and

a layer 2 switch. Computers and the wireless access point will connected to the layer 2 switch


For the first floor we are going to use 16 ports Layer 2 .Wireless access point and the

computers will be connect to a patch panel and that will be connected to the switch.


20/40


20

4.4.3 Second Floor

Floor Plan

This area must be leaved for future enhancements. So we left this area to be a free area.

Network Plan


As shown above, this floor only has a layer 2 switch.

This floor should be a free undecided area for any purposes. So we are planned to fix a 64

port layer 2 switch so that we can fix large number of devices to that easily in the future.


21/40


21

4.5 Building 4

4.5.1 Ground floor

Floor Plan

Ground floor of this building is planned to be used as examination hall and the floor will be

partitioned into five exam halls.

Network Plan


As revealed in the above figure this floor consists of a wireless access point which is

connected to a layer 2 switch .Layer 2 switch will be the main switch in an every floor in the

entire building

As for the ground floor main switch will be an eight port layer 2 switch is going to be used..Wireless access point is connected to a Patch Panel and it is connecting to the layer 2 switch.

When any device which is fixed to the switch go doesnt work that should be removed from

the switch.. If either the cable or the switch get damaged when we are removing the cable

from the switch that will cost a lot of money as they cost a lot. The purpose of the patch panel

is to protect the switch and the cable by connecting the both switch and the cable to that and

make the connection of them inside the patch panel.


22/40


22

4.5.2 First Floor

Floor Plan

This floor is going to be use to have six classrooms, three syndicate rooms and two court

rooms.

Network Plan

As shown below this floor will have six computers, wireless access point and a layer 2

switch. Computers and the wireless access point is going to be connected to the switch


We are going to use 16 ports Layer 2 switch .Wireless access point and the computers will be

connect to a patch panel and that will be connected to the switch.


23/40


23

4.5.3 Second Floor

Floor Plan

This is to be leaved for future enhancements

Network Plan


As shown above this floor only has a layer 2 switch.

This floor should be a free area which supposed to be decided later by the APIIT Law School

authority. So we are planned to fix 64 ports, layer 2 switch so that we can fix large number of

devices to that easily in the future.

4.6 Network Cabling

In our proposed network plan to APIIT law school we are requesting to use the be law cables.

1. CAT 5e cables

2. CAT 6e cables

3. Fiber Optics Cables

CAT 5e cables

This is the developed version of CAT 5 cables. There are four pairs of copper twisted cables

inside this cable. This has a speed of 100oMbps and carry signals for 100m.Benifit of this

cable is it has a lesser chance of meddling with another cable which is also running in the

same track. This is preferred to travel data for short distances. So in our proposed network

system we are planning to use this cable to connect devices to the patch panel and connect the

switch and the patch panel as the distance between them is lesser. After consideration the cost

of the cable and ease of the fixing we decided to use this for above purposes.

(CableOrganizer.com. 2002)

25

CAT 6e cables

This cable also much more similar to the CAT 5 /CAT 5 e cable the only main difference

which make CAT 6e better than them is a one structural difference which is called as

longitudinal separator. Longitudinal separator. This separator isolates the four pairs of twisted

cables which will reduces crosstalk, allows for faster data transfer and also has a higherbandwidth comparing to the CAT 5e cables. So we are planning to use that to connect the

Layer 2 switches to patch panel and Layer 3 switches to the panel in order to connect layer 2

and layer 3 switches. This also again uses to connect layer 3 switches in an every building to

the backbone layer 3 main switch. All the cables are always dont connect to the devices

directly they are connecting to each other with the use of the patch panel.


Fiber Optics Cables

Fiber optics is one of the latest methods of transferring data. The reasons for been so famous

among those copper is the low cost, high data carrying capacity and also as there is no fear of

any danger such as fire as there is no electricity. The other advantages of fiber optics are that

they have a highest bandwidth and also the signal loss is totally reduced in fiber optics.

So because of these reasons we planned to use fiber optics to connect the four Law School

Buildings and the APIIT main building.

4.7 Wireless Connectivity

According to network diagram in each and every building floor will have a wireless access point. When we want to connect to a wireless connection we should connect the wired

equivalent privacy key. Because if not hackers or crackers can easily enter the network.

In every floor wireless access point is in the middle of the floor. It covers 360 degrees. Ifwired access points signal strength not enough to floor then use the wireless extenders for

alternative Wi-Fi solutions.

(About.com 2010)

(Internet.com 2010)

Wireless Network Standards

Wireless network standards are created by Institute of Electrical and Electronics Engineers

(IEEE). It founded in 1884. Here are some IEEE standards.

y 802.11y 802.11ay 802.11by 802.11g

In our networking diagram we are planning to use IEEE standards of 802.11 and 802.11a

802.11

This standard is develops for wireless LANs standards. These wireless LANs gets 1 or 2transmissions in the 2.4 GHz band. Also this has been expended in 802.11d standard version.

802.11a

This wireless LAN provides up to 54 Mbps in the 5 GHz. These products of standards areconsidered as Wi-Fi certified.

5.0 Linking the APIIT city campus and the APIIT law school

Figure 15: Linking between the two campuses

This is a very important part of the applied network proposal. As the users of one building

should be able to connect and communicate with the other buildings, as well as share

resources we have to consider a type of connection. The network consultants in our group

proposed to use a VPN after considering a possible use of point-to-point and remote access.

Research has been conducted on the types of connections mentioned above, the reason for

choosing VPN over the other two types of connections has been explained below:

y Point-to-Point (Wireless access)y VPN (Virtual Private Network - wired)


28/40


28

Point-to-Point

Point-to-Point access is a lot cheaper compared to VPN; this is implemented by using a

wireless bridge each placed on the respective buildings and are linked to the network using

radio frequency. Aside from the low cost, this connection has a few issues which include

exposure of radio signals to places outside the internal network. When radio signals are

exposed, people in the external environment (outside the internal network) will be able to

hack into the system, therefore this leads to a serious security issue where all APIITs

confidential data will be exposed to outside parties. Another disadvantage of point-to-point

would be that the weather is likely to affect the transmission of data.

VPN (Virtual Private Network)

A virtual private network (VPN) is a network that uses a dedicated private line which is

virtually private to provide connections between offices, remote workers and the Internet.

(Annabel Z. Dodd. 2005)

This can also be described as a dedicated and secure path provided by the ISP (Internet

Service Provider) to connect between LAN networks. In our network proposal we have

decided to use leased lines from SLT and dialog, these are used for internet access. So with a

VPN when we go online or try to communicate with the other buildings network the data

that is transferred will be encrypted, therefore making it harder for external networks to gain

access to the VPN. This method is reliable and secure, but the main disadvantage is the cost

of purchasing the required leased lines. However compared to Point-to-Point access this, a

VPN is far more efficient.

6.0 Backup plans

Using RAID systems

Mainly there are two types of RAID systems. They are hardware arid systems and software

raid systems. The purpose of using RAID systems are speed of the hard drives and the

automatically backup data.

In here we are using RAID 1 system for our network. It called as Mirror technique or

Duplexing technique. Its a fault tolerance system. According to mirror system this has two

hard drives for same data. If one hard drive fails nothing will happens same thing happens

from the other hard drive.

(Charles M. Kozierok 2001)

(Western Digital2010)

Source: http://www.raids.co.uk/raid_0+1.htm

Dual Backbone Implementation

According to this network plan building one 2nd

floor has the server room. It uses Layer 3,

3com backbone switch. If there will be any emergency and the backbone switch will bebroken down hole network will be disaster. Because of that we use an alternative backbone

switch for our network.

(Elsevier B.V. 2010)

(IEEE 2010)


30/40


30

Remote backup

If physically network will be damaged easy to have a backup server in a remote distance area.This backup will be sending online from the internet and physically stores in the remote

place.

(Online Holdings 2010)

Backup Cables

We have used backup cables in our network proposal, so if there is damage occurred to a

cable it would still have backup cables to replace it.


31/40

7.0 Conclusion

After discussing and researching on the types of networks and connectivity options, we

decided to connect all four buildings of the APIIT Law School using Fiber Optic cables and

also we used Fiber optic cables to connect the Law School to the main APIIT Campus

Building.

Aside from the cabling we have decided to link the two Campuses using a Virtual Private

Network (VPN) connection, because a VPN is more secure and reliable than other types of

connections such as Point-to-Point access.

Backup Plans have been implemented by using backup cables such as CAT5e cables, etc; so

that in the event that a cable is not working it will be replaced by the backup cables. RAID

system is used to back-up data, as well as Remote back-ups and Dual-backbone

implementation.

Overall researching about types of networks, connections, cables and other equipment had

both been a challenging and an educational experience.
