INTRODUCTION
1.1
Project Background
As to klfill the requirements for Projek Sarjanu Muda 1, all third year students
of Computer Science majoring in Networking have to choose either to develop system,
carrying out a research (case study) or do analysis on protocols. As for this project, a
research will be carried out and for that, an organization has to be selected in order to
be the client for this research. The organization can be a company, a university, a
college, a factory or a government department. So, to carry out this network analysis
and design project, Universiti Teknologi Mara (UiTM) Melaka has been selected as the
organization to do the research.
UiTM Melaka is an educational institute which provides higher level
educational services to it students. At this moment, the administration of UiTM,
especially the staffs from Department of Information Technology is not very satisfied
with the network performance there since it is not very stable, slow and can easily be
attacked by viruses. So, the network design need to be analyzed in order to identify the
source of the problems and try to solve the problem of the existing network by coming
out with a new network design for UiTM Melaka. Besides, there were also only wired
network install there and no wireless network had ever been implemented. A
simulation using OPNET Modeler will be used to present the result of the analysis so
that the administration can understand it well and better.
1.2
Problem Statements
There are some problems that have been identified to exist in the existing
network design of UiTM Melaka and they are:
The cable used is not suitable with the organization needs.
J
The cables that are being used are UTP cable category 5 (cat5). Cat 5
provides performance of only up to 100 MHz and this is not fast
enough to support multiple usage of internet and to support multiple
applications used.
The networks there can easily being attacked by viruses.
J
This happens since the network protection there is directly controlled
by the main campus at Shah Alam. There is no firewall or proxy being
implemented there in order to overcome attacks from viruses.
According to Mr. Farid who is the information technology assistant
manager there, they only rely on the antivirus software to protect their
network.
The network performance is slow and not stable.
J
This happens because the network there, especially access to the
internet is being directly controlled by the main campus at Shah
Alam. For example, if students want to access the internet, their
requests firstly will have to go through the server room at UiTM
Melaka and then the requests will be sent to server room at UiTM
Shah Alam and then, from Shah Alam the requests to the internet will
be processed and students can use the internet then.
The existing network does not have the capability to support multiple
applications such as file sharing and network printing to be run synchronize.
The existing network does not have the capability to cater with multiple
major network requirements.
1.3
Objective
The objectives that would like to be achieved upon completing this project are:
To demonstrate the benefits of using OPNET Modeler in analyzing and
simulating network design of UiTM Melaka.
J
Before any implementation can be made, the simulation on the current
and new network design need to be done. The simulation will help on
the implementation of the new network for UiTM Melaka. The data
which is needed for the simulation is the probability of any problem
that can occur during the implementation and the performance of the
network. This is important as the data will show the possibility of
problem and the performance of network
Enhancement to UiTM Melaka existing network.
J
Enhancement of the existing network is needed in order to improve
the network performance, to increase the quality of service provided
and to overcome the problems that arose in the existing network
design.
To configure the servers with proper applications using OPNET Modeler in
order to facilitate the administration in managing the network utilization and
security. This is done to improve the quality of network service at UiTM
Melaka.
To suggest the administration of UiTM Melaka a way on how to improve the
service provided by their network such as fast access time to the internet.
1.4
Scope
The scope of this project can be divided into two main categories which are:
J
Scope of user.
J
Scope of project.
1.4.1 Scope of user
Scope of user consists of three, which are the UiTM Melaka students, UiTM
Melaka staffs and also the UiTM Melaka administration itself.
8
UiTM students.
J
They will surf the internet in order to search for information and
completing assignment given by their lecturers.
UiTM staffs.
J
They will use the internet to finish up the jobs assigned to them.
UiTM administration.
J
They will be responsible for monitoring the network performance and
provide user with the desired application.
1.4.2 Scope of project
In order to improve the quality of network service at UiTM Melaka, a new
network configuration and network design will be implemented for the whole campus
area. The scope of this project can be stated as:
Configured servers.
J
The servers used by UiTM Melaka are being configured for a better
security performance and to increase the network load.
Whole floor network transmission medium.
J
In this project, all current networks cabling used by UiTM Melaka is
being analyzed in order to know the problems which arose from it. As
a result, certain areas will be equipped with new cabling.
Designed a new network in order to improve network performance of the
existing network.
J
In this project, analysis on the existing network is being carried out in
order to gain more information and more knowledge about the current
network environment of UiTM Melaka. The analysis on the existing
network will help and facilitate the task of developing a new network
for UiTM Melaka.
Developed a network simulation using OPNET Modeler.
J
A network simulation for the existing network design and the propose
network design (new design) will be developed in order to give
clearer view and better understanding about the project being done.
The type of software that will be used for implementing those designs
is OPNET Modeler.
1.5
Project Significance
This project is important because it can help to find ways and solutions in
overcoming all the problems that are reported to occur in the current network design of
UiTM Melaka. Upon completing the task of analyzing the network design of UiTM
Melaka, a new network design and report will be produced which are aimed to help to
improve the network performance there and to overcome all the problems and
weaknesses which happen to occur in the current network design. The most important
and significant aspect of this project is improving the quality of network performance
at UiTM Melaka. The new network design is also aimed to facilitate the administration
of UiTM Melaka in monitoring and managing their network.
1.6
Expected Output
The expected output that are going to obtained upon completing this project is a
new network design which can replace the existing or current network design of UiTM
Melaka. The new design is aimed to overcome all the problems which are reported to
occur or happens in the current design. The new design will come out in both designs
which are logical and physical design. From the problems that have been stated earlier,
the following solutions are proposed in order to solve it and they are:
Changing the type of cable used with the one which are capable for
supporting the organization needs and used.
Securing the network there by enabling firewall and proxy protection
from within the place and not directly from main campus at Shah Alam.
Increasing the bandwidth of internet provided at UiTM so that surfing
the internet can be faster and more efficient.
1.7
Conclusion
This project is done in order to analyze network design at UiTM Melaka and
then implements it using OPNET modeler. The purpose of doing this project is to
improve network performance at UiTM Melaka and then to come out with a new
network design which can replace the existing design. A new network design is needed
because there have been problem arose in the existing network design such as low and
slow connectivity to the internet.
This chapter is written mainly to give clearer understanding about the project
which is going to be developed. Besides, it also will briefly describe about the
current situation faced by UiTM Melaka regarding the network performance there.
By viewing this chapter, one then can understand and know a little bit about the
background of this project, the problems of using the existing network, the objectives
that would like to be achieved upon completing this project and also the scope of this
project. At the mean time, the importance of doing this project is also explained in
the topic entitled project significance.
The next chapter, which is chapter I1 will describe about the literature review
and the methodology that are going to be used to develop this project. This chapter
required students to understand, knew their topic well and understand the
requirements needed for their project. And to complete this chapter, some researches
need to be camed out in order to collect the required information. Research can be
done through the website, journals and so on. Examples of output that are going to be
gained from this chapter are project schedule and milestones.

CHAPTER I
INTRODUCTION
1.1
Project Background
As to klfill the requirements for Projek Sarjanu Muda 1, all third year students
of Computer Science majoring in Networking have to choose either to develop system,
carrying out a research (case study) or do analysis on protocols. As for this project, a
research will be carried out and for that, an organization has to be selected in order to
be the client for this research. The organization can be a company, a university, a
college, a factory or a government department. So, to carry out this network analysis
and design project, Universiti Teknologi Mara (UiTM) Melaka has been selected as the
organization to do the research.
UiTM Melaka is an educational institute which provides higher level
educational services to it students. At this moment, the administration of UiTM,
especially the staffs from Department of Information Technology is not very satisfied
with the network performance there since it is not very stable, slow and can easily be
attacked by viruses. So, the network design need to be analyzed in order to identify the
source of the problems and try to solve the problem of the existing network by coming
out with a new network design for UiTM Melaka. Besides, there were also only wired
network install there and no wireless network had ever been implemented. A
simulation using OPNET Modeler will be used to present the result of the analysis so
that the administration can understand it well and better.
1.2
Problem Statements
There are some problems that have been identified to exist in the existing
network design of UiTM Melaka and they are:
The cable used is not suitable with the organization needs.
J
The cables that are being used are UTP cable category 5 (cat5). Cat 5
provides performance of only up to 100 MHz and this is not fast
enough to support multiple usage of internet and to support multiple
applications used.
The networks there can easily being attacked by viruses.
J
This happens since the network protection there is directly controlled
by the main campus at Shah Alam. There is no firewall or proxy being
implemented there in order to overcome attacks from viruses.
According to Mr. Farid who is the information technology assistant
manager there, they only rely on the antivirus software to protect their
network.
The network performance is slow and not stable.
J
This happens because the network there, especially access to the
internet is being directly controlled by the main campus at Shah
Alam. For example, if students want to access the internet, their
requests firstly will have to go through the server room at UiTM
Melaka and then the requests will be sent to server room at UiTM
Shah Alam and then, from Shah Alam the requests to the internet will
be processed and students can use the internet then.
The existing network does not have the capability to support multiple
applications such as file sharing and network printing to be run synchronize.
The existing network does not have the capability to cater with multiple
major network requirements.
1.3
Objective
The objectives that would like to be achieved upon completing this project are:
To demonstrate the benefits of using OPNET Modeler in analyzing and
simulating network design of UiTM Melaka.
J
Before any implementation can be made, the simulation on the current
and new network design need to be done. The simulation will help on
the implementation of the new network for UiTM Melaka. The data
which is needed for the simulation is the probability of any problem
that can occur during the implementation and the performance of the
network. This is important as the data will show the possibility of
problem and the performance of network
Enhancement to UiTM Melaka existing network.
J
Enhancement of the existing network is needed in order to improve
the network performance, to increase the quality of service provided
and to overcome the problems that arose in the existing network
design.
To configure the servers with proper applications using OPNET Modeler in
order to facilitate the administration in managing the network utilization and
security. This is done to improve the quality of network service at UiTM
Melaka.
To suggest the administration of UiTM Melaka a way on how to improve the
service provided by their network such as fast access time to the internet.
1.4
Scope
The scope of this project can be divided into two main categories which are:
J
Scope of user.
J
Scope of project.
1.4.1 Scope of user
Scope of user consists of three, which are the UiTM Melaka students, UiTM
Melaka staffs and also the UiTM Melaka administration itself.
8
UiTM students.
J
They will surf the internet in order to search for information and
completing assignment given by their lecturers.
UiTM staffs.
J
They will use the internet to finish up the jobs assigned to them.
UiTM administration.
J
They will be responsible for monitoring the network performance and
provide user with the desired application.
1.4.2 Scope of project
In order to improve the quality of network service at UiTM Melaka, a new
network configuration and network design will be implemented for the whole campus
area. The scope of this project can be stated as:
Configured servers.
J
The servers used by UiTM Melaka are being configured for a better
security performance and to increase the network load.
Whole floor network transmission medium.
J
In this project, all current networks cabling used by UiTM Melaka is
being analyzed in order to know the problems which arose from it. As
a result, certain areas will be equipped with new cabling.
Designed a new network in order to improve network performance of the
existing network.
J
In this project, analysis on the existing network is being carried out in
order to gain more information and more knowledge about the current
network environment of UiTM Melaka. The analysis on the existing
network will help and facilitate the task of developing a new network
for UiTM Melaka.
Developed a network simulation using OPNET Modeler.
J
A network simulation for the existing network design and the propose
network design (new design) will be developed in order to give
clearer view and better understanding about the project being done.
The type of software that will be used for implementing those designs
is OPNET Modeler.
1.5
Project Significance
This project is important because it can help to find ways and solutions in
overcoming all the problems that are reported to occur in the current network design of
UiTM Melaka. Upon completing the task of analyzing the network design of UiTM
Melaka, a new network design and report will be produced which are aimed to help to
improve the network performance there and to overcome all the problems and
weaknesses which happen to occur in the current network design. The most important
and significant aspect of this project is improving the quality of network performance
at UiTM Melaka. The new network design is also aimed to facilitate the administration
of UiTM Melaka in monitoring and managing their network.
1.6
Expected Output
The expected output that are going to obtained upon completing this project is a
new network design which can replace the existing or current network design of UiTM
Melaka. The new design is aimed to overcome all the problems which are reported to
occur or happens in the current design. The new design will come out in both designs
which are logical and physical design. From the problems that have been stated earlier,
the following solutions are proposed in order to solve it and they are:
Changing the type of cable used with the one which are capable for
supporting the organization needs and used.
Securing the network there by enabling firewall and proxy protection
from within the place and not directly from main campus at Shah Alam.
Increasing the bandwidth of internet provided at UiTM so that surfing
the internet can be faster and more efficient.
1.7
Conclusion
This project is done in order to analyze network design at UiTM Melaka and
then implements it using OPNET modeler. The purpose of doing this project is to
improve network performance at UiTM Melaka and then to come out with a new
network design which can replace the existing design. A new network design is needed
because there have been problem arose in the existing network design such as low and
slow connectivity to the internet.
