ABSTRAK

Kebanyakkan institusi termasuk institusi pendidikan amat bergantung kepada

rangkaian untuk menyebarkan maklurnat serta menyiapkan kerja. Politeknik Tuanku

Syed Sirajuddin (PTSS) merupakan institusi pendidikan yang menggunakan

rangkaian untuk tujuan pendidikan serta operasi institusi dapat dilaksanakan dengan

efektif. Walaubagaimanapun, operasi yang efektif di PTSS terjejas disebabkan oleh

prestasi rangkaian yang semakin lemah. Untuk mengekalkan kadar yang efektif,

adalah penting untuk mengawasi bagaimana sistem rangkaian berfungsi dan

digunakan oleh pengguna. Tinjauan awal mendapati masalah yang mungkin memberi

impak kepada jalur lebar rangkaian ialah sikap buruk pengguna. Untuk menangani

masalah tersebut, alat pengawasan rangkaian Cymphonix telah digunakan dalam

kajian ini untuk mengawasi rangkaian. Kajian ini hanya fokus kepada rangkaian

VLAN 20. Pengawasan dilaksanakan sepanjang lima hari bekerja dalam tempoh

semester pembelajaran pada masa waktu bekerja. Data utama yang diambil dari alat

pengawasan dalam kajian ini ialah trafik Internet, jalur lebar aplikasi serta jenis-jenis

aplikasi yang wujud. Data-data tersebut dianalisis untuk mengenalpasti jenis-jenis

aplikasi Internet dan kaitkannya dengan tabiat pengguna rangkaian. Hasil daripada

kajian mendapati trafik aplikasi Internet di rangkaian VLAN 20 adalah sentiasa

berubah-ubah pada setiap hari. Kebanyakkan trafik adalah dari aplikasi HTTP.

Aktiviti utama pengguna dalam VLAN 20 ialah melayari web dan memuat turun fail.

Malah, trafik dari aplikasi yang boleh menyebabkan penggunaan rangkaian menjadi

lemah seperti P2P dan media streaming tidak menunjukkan kadar pengguaan jalur

lebar yang banyak. Ini menunjukkan bahawa tabiat pengguna dalam rangkaian

VLAN 20 bukan merupakan faktor utama yang menyebabkan penggunaan rangkaian

di PTSS menjadi lemah. Walaubagaimanapun, kajian lanjut perlu dilaksanakan untuk

mengenalpasti penyebab utama yang menyumbang kepada masalah rangkaian di

PTSS seperti menggunakan alat pengawasan yang boleh membaca semua jenis

traffik yang tidak dikenali serta melaksanakan kajian ke atas rangkaian VLAN yang

lain di PTSS untuk menilai samaada pengguna dalam rangkaian VLAN tersebut

memberi kesan negatif kepada penggunaan rangkaian di PTSS.

ABSTRACT

Most of the institutions included education institutions heavily rely on networks to

distribute information and to get job done. Polytechnic Tuanku Syed Sirajuddin

(PTSS) is one of the educational institution that used network for educational and for

effectiveness of institution operational. However, the effectiveness of PTSS

operational was disturbed due to the network performance become slowly. To

maintain the effectiveness, it is important to monitor how the network system

working and used by users. The early observation found that, one of the possible

problems impacts the network performance is users bad behavior. To overcome the

problems, Cymphonix network monitoring tool used in this study to monitor the

network. This study only focuses on network VLAN 20. Monitoring was done during

five working days in semester study within office working hours. The main data

capture from monitoring tool used in this study are total Internet traffic, application

bandwidth and types of application that appear in the network VLAN 20. The data

captured were analyzed to identify the Internet application types and relate it to the

behavior of the network users. Result from the study indicates that Internet

application traffic in network VLAN 20 is fluctuating for every day. Most of the

traffic is from HTTP application. Main activities of users in network VLAN 20 is

only web browsing and download files. Moreover, the traffic of application that can

causes of network performance become slow such as P2P and streaming media are

not much consume the range of bandwidth. This is shows that behavior of the users

in network VLAN 20 is not main factors that cause network performance in PTSS

slow. However, there are some further studies required to identify main causes that

contribute to the network problems in PTSS such as used other type of tool that

enable to capture all the uncategorized traffic and study on other VLAN network in

PTSS to evaluate whether users in that VLAN network causes negative impact to the

performance of network in PTSS.

ACKNOWLEDGEMENT

I am heartily thankhl to my project supervisor, Dr. Massudi Bin Mahmuddin for his

guidance, valuable suggestions, kindness and promptness in reviewing my final

project. His guidance helped me in all the time to study and writing of this report.

I would also like to thank and highly appreciate to Mr. Muhammad Hafiz Bin Razi,

Head of Unit of Information Technology & Communication (UITC) in PTSS for his

help, suggestion and guidance for me to complete this study. I thank to the

coordinators for the post-graduates studies at the Information Technology Faculty of

Universiti Utara Malaysia for their continuous help. My sincere thanks also go to my

colleagues in PTSS for their encouragement and help.

I am deeply and forever indebted to my family and my fiance for their love, support,

encouragement and understanding.

Lastly, I offer my regards and blessings to all of those who supported me in any

respect during the completion of this project.

CHAPTER ONE

INTRODUCTION

1.0 Introduction

Polytechnic Tuanku Syed Sirajuddin (PTSS) is an education institution having about

4,5 13 students and 367 staffs. PTSS building construct into several buildings include

administrator buildings and eight main academic department buildings which every

department have provided with computer labs, classrooms and department main

office. Most of the students and staff live on campus and majority of them have at

least network devices such as personal computer or laptop. Students and staffs owned

computers, along with approximately 3,000 network devices in the form of office

and lab computers and servers. Due to the increased of numbers of users and network

devices, the campus network has experiences tremendous growth in the volume of

traffic and put heavy demand on bandwidth.

Altogether, PTSS has approximately 26 Mbps of Internet bandwidth which is

combination of three bandwidth packages include MyRen 10 Mbps, TMNet Direct 4

Mbps and Streamyx Line 12 Mbps. All of the Internet bandwidth packages are

purchased from one ISP. The bandwidth packages purchased from the provider is not

equal and used to combine altogether in one pipe link as a load balancer. The overall

network consists of nineteenth VLAN network segments connected by router and

switch. VLAN network are created for each separate department for better control of

resources and to minimize the broadcast domain for a certain network segment.

However, there are some numbers of VLAN network builded to covers two or more

departments or Units such as VLAN 20 is builded to covers two departments which
