ABSTRACT<br />

In this borderless world, it is important to have a responsive environment for<br />

retrieving data or information as it is a key component of the information system<br />

infrastructure of modern research projects. Due to the rapid growth of the global<br />

Internet, researchers are demanding an improvement of traditional techniques for data<br />

storage in order to get desired information in a convenient fashion and at a higher<br />

speed. Malaysian Research and Education Network (MyREN) is introduced to<br />

interconnect educational and research institutions in Malaysia. With its high-speed<br />

broadband network, researchers would be able to carry out their research projects that<br />

involve data-intensive applications as well as sharing resources across the network.<br />

Furthermore, the network is more economical compared to other commercial<br />

networks that will not guarantee for higher performance network. This project<br />

presents a deployment platform for web servers to link to the MyREN network. The<br />

server would be able to cater any applications such as bioinformatics and industrial<br />

databases that can be shared among MyREN's members.<br />

1.0 Background<br />

CHAPTER 1<br />

INTRODUCTION<br />

National Research and Education Network (NREN) is a dedicated Internet<br />

service provider that supports the needs of the research and education communities<br />

within a country. Thus, academia and researchers will get networks with high<br />

bandwidth and low latency which are important for collaboration works and resource<br />

sharing among institutions. To date, there are more than 70 NRENs around the world.<br />

Malaysian Research and Education Network or better known as MyREN was<br />

launched on 28 March 2005. The purpose of introducing MyREN is to interconnect<br />

educational and research institutions. Currently MyREN connects fourteen<br />

universities and research institutions throughout Malaysia via a nationwide Internet<br />

Protocol (IP) backbone at 45Mbps capacity. MyREN's high bandwidth capacity<br />

allows data-intensive applications such as bio-modeling and computation as well as<br />

sharing of resources to be conducted more efficiently where high computing assets<br />

can be shared across organizations [1], The backbone covers eight states in the West<br />

and East of Malaysia. Members are connected to MyREN via their respective access<br />

link, which can either be a fibre link or microwave link. The access connection varies<br />

according to the user's requirements. MyREN connectivity is centralized at MyREN<br />

Network Operation Centre (NOC) which is located in Cybeijaya.<br />

After more than three years, the MyREN link utilization is still low where<br />

some universities have the utilization below 1%. Ministry of Higher Education<br />

(MOHE) has reported that the usage of MyREN is extremely low compared to the<br />

amount of money that the government has spent. In Universiti Teknologi MARA<br />

(<strong>UiTM</strong>), there is no activity has been done on MyREN. Due to that reason, this<br />

project will focus on developing a platform for web applications and resources to be<br />

shared among MyREN members from <strong>UiTM</strong>'s server.<br />

1.1 Research Objectives<br />

The objectives of this project are:<br />

1.2 Scope of Work<br />

• To develop a web server host for remote access to MyREN.<br />

• To built links from <strong>UiTM</strong> to other MyREN's members.<br />

This project provides a platform for web server that can link <strong>UiTM</strong> to<br />

MyREN's members. The server would be able to cater any applications such as<br />

ioinformatics and industrial databases that can be shared among MyREN's members.<br />

The project work is carried out in four different stages as listed below.<br />

• Literature review<br />

o Literature review on existing National Research and Education<br />

Network (NREN) around the world and web server development,<br />

o Related works on web server development over NREN are reviewed,<br />

o Study and understand the network topology and operation of MyREN.<br />

o Study the MyREN topology in <strong>UiTM</strong>.<br />

• Web server development<br />

o The process of designing the web server system is divided into four<br />

activities:<br />

• MyREN configuration<br />

1. Development of Virtual Server and Client-Server<br />

2. Development of Database.<br />

3. Development of Website.<br />

4. Deployment of Web Server.<br />

o Get the fixed IP address for MyREN from Centre for Integrated<br />

Information System (CIIS), <strong>UiTM</strong>.<br />

o Install the web server at the MyREN infrastructure in CIIS, <strong>UiTM</strong>.<br />

o Apply Domain Name Server (DNS) from MyREN Network Operation<br />

Centre (NOC). The server IP address is then mapped to the DNS. The<br />

server is then configured so that it is accessible by MyREN members<br />

only.<br />

• Functionality test and performance evaluation<br />

1.3 Report Structure<br />

o Test the functionality of the whole system, i.e. get another MyREN<br />

member to access the database.<br />

This report comprises of five chapters. The first chapter briefly describes the<br />

overview of MyREN, research objectives and the scope of this project. Chapter 2<br />

focuses on the literature review that would discuss about NREN, MyREN in depth<br />

and other related works that have been done by other researchers.<br />

Chapter 3 outlines the process of developing the web server system. The<br />

process consists of the development of virtual server, client server, database, website<br />

and web server. MyREN configuration and the installation of the web server at the<br />

MyREN infrastructure are also described thoroughly in this. The configuration<br />

process is carried out with the help from the personnel at CIIS in <strong>UiTM</strong> and MyREN<br />

NOC at Cybeijaya. Once it is configured, the web server is then installed at the <strong>UiTM</strong><br />

MyREN infrastructure at CIIS. The IP address is then mapped to the DNS.<br />

COPYRIGHT@<strong>UiTM</strong><br />

Chapter 4 focuses on the functionality test results. The functionally test is<br />

performed from the server site and client site.<br />

Finally, the whole report is concluded in Chapter 5. It gives the detailed<br />

discussions of the project and possible research that can be done in future.<br />

2.0 Overview<br />

CHAPTER 2<br />

LITERATURE REVIEW<br />

A National Research and Education Network (NREN) is a dedicated network<br />

that supports the needs of the research and education communities within a country. It<br />

is usually offer a high-speed backbone network and dedicated channels for research<br />

that will not be interrupted by other background traffic.<br />

Malaysian Research and Education Network or better known as MyREN<br />

connects several universities and research institutions throughout Malaysia via a<br />

nationwide IP backbone at 45Mbps capacity. MyREN's high bandwidth capacity<br />

allows data-intensive applications and sharing of resources to be conducted more<br />

efficiently.<br />

This chapter focuses on the review on NRENs and particularly on MyREN.<br />

Related works in developing web server over the NRENs are also outlined in this<br />

chapter.<br />

2.1 National Research and Education Network (NREN)<br />

NREN is a dedicated Internet service provider that supports the requirements<br />

of the research and education communities within a country. It is usually supported by<br />

a high-speed backbone network that normally offers dedicated channels for individual<br />

research projects. Consequently, researchers and educators will be provisioned with a<br />

higher bandwidth network with no interruption from the background traffics.<br />

Furthermore, if NRENs are properly implemented, it could demonstrate how a<br />

broadband network can be used in future as well as working as a test-bed for new<br />

technologies, applications and governing policies that will lead to the larger national<br />

network [2],<br />

2.2 Malaysian Research and Education Network (MyREN)<br />

MyREN is a National Research and Education Network in Malaysia that is<br />

used by the researchers in Malaysia for collaborative research. With the high-speed<br />

broadband network, researchers would be able to carry out their research project that<br />

involved data-intensive applications as well as sharing resources across the network.<br />

Furthermore, the network is more economical compared to other commercial<br />

networks that will not guarantee for higher performance network. On top of that, the<br />

network can also be used as a platform for the researchers to test their findings prior<br />

to the deployment in the market without jeopardizing the main network in their<br />

respective institutions.<br />

To date, MyREN connects sixteen members which consist of universities and<br />

research institutions in Malaysia via a nationwide IP backbone at 45Mbps capacity as<br />

depicted in Figure 2.1. The backbone covers eight states in the West and East of<br />

Malaysia and centralized at MyREN Network Operation Centre in Cybeijaya.<br />

Members are connected to MyREN via their respective access link, which can either<br />

be a fiber link or a microwave link depending on their requirements. With more<br />

bandwidth intensive applications and greater user demand, it is envisaged that<br />

MyREN will evolve to a larger scale network in the following phase. MyREN<br />

backbone is versatile to support all types of traffic such as video conferencing, digital<br />

video transport system (DVTS), data computing, visualization/image modeling and e-<br />

learning [1].<br />
