1. Chapter 1: Introduction
1.1 Project Background
Nowadays most business rely on computer and network infrastructure, therefore the
computer network’s speed and reliability are very important for the business to be successful
with efficient use of the resources available. For the network administrator, it means that he must
make sure that the network speed and the usage of the other networks are always on the same
level. To do this, monitoring the network is certainly important.
Computer networks are crucial part of an organization in this era of technology
advancement. Knowledge of designing a software tool is needed nowadays to troubleshoot an
organization’s computer or an office computer. Lan Monitoring System (LMS) is the system
which is scoped to organizations for network administrators to monitor the activities of the other
network and CPU in the organization. When an organization expands its business, the number of
network increases as well. Therefore, the speed of the network will be affected and the respond
time needed to display the Web Pages or streaming videos and etc; will be delayed. These
network problems can cause business to lose money due to time consuming by calling network
engineers to solve those problems and such problems must be resolved to eliminate loses.
Besides that, the most important thing is when lots of users are using the pc on the same
network and the number of pc in the LAN gets bigger and larger, it is difficult to know who
actually misusing the network .Problems will arise for an organization if a hacker gets into the
network. Every user’s information and data will be stolen and the computers might get attacked
by viruses that are sent by suspicious or unknown IP addresses which will damage the computers
health and performance. Moreover, the current ways of transferring files from a department to
another department is by sending it through a dispatch to the staffs.
This could consume a lots time where dispatch needs to wall all the way the next floor to
deliver a file. Besides that the usage of emails to transfer files are not reliable due to
unguaranteed security. Apart from that, the other problems faced by organizations are
communication problem within admin and staffs. Sending email of latest information updates
and pasting it on announcement boards could further consume time and energy.

2. 1.2 Problem Context
According to Edmund Wong (2010), the internet is getting hard to control and monitor as
the users are increasing. It does not have a standardized metric or monitoring tool to control it
nor even a researched being done or developed. Edmund Wong (2011) added that the only
solution to monitor the internet is by using the current public software’s and extending their
functionalities. However, there are few problems with this method. First of all, the public
software’s are not fully meant to monitor.
The only perform minimum monitoring activities because they eat up the network
capacity. Besides that, not many people are monitoring the internet since it is a difficult job.
Thus, it results in degrading of the internet performances as not many problems are being
reported and solved frequently. This phenomenon that is created due to the lack of monitoring is
called “gridlock”. Apart from that, Darragh Delaney (2011) stated that alerting about critical
infrastructure should be made to IT staffs during their working hours. Alerting is also useful to
alert specific server and application teams.
The researcher proposed this Lan Monitoring System after many researches done by
reading the journals and articles related to various network management systems. Those systems
have tested their performance on bandwidth monitoring and how to manage information of
network elements and monitor error on real-time. Therefore, the researcher will develop the
proposed system by taking related features of the proposed system, by combining several
functionality systems.

3. 1.3Objective of the Project
The Objective of this system is that it provides details of information and analysis of a
network that help office users to handle to maintain the networks performance stable and
efficient. By this way, the department or the company can save a lot of money and time for not
calling the technician to fix up the network problem.
Moreover, in the proposed system it consists of monitoring network bandwidth .When
this system starts running, it will monitor each and every packet that goes in and out from the
network. By monitoring the network traffic this system enables to check status for the every part
of the office network so that the administrator can know the whole situation and condition on
their company’s network.

4. 1.4Scope of the Project
LMS allows network administrators to monitor the current activities of the network and
the PC. It helps the administrators to troubleshoot problems relating to slow processors in
computer and networks. This system also includes File transfer Protocol where staffs would not
need to travel from one floor to another just for the sake of sending documents and files.
Furthermore, this system has the features of chatting which can send out information, office
news, and updates to the whole organization which is connected to this LMS system.

5. Chapter 2: Literature Review
2.1 Review of Current Situation
Network Monitoring in an organization is a very important IT function which is able to save
money in network performances and employee productivity. Internal network problems are
normally monitored by Network Monitoring Systems. It able to search and solve slow web page
downloads, lost emails and crashed servers. Therearemany software or mixture of hardware can
be used to monitor all kind of networks virtually including wireless and wired. Moreover,
devices such as cell phones, routers, and switches with different operating system can also be
monitored.
2.2 Review of Related Literature
Normally the areas that network monitoring system covers are the usage of bandwidth,
application performance and pc performance. Monitoring the traffic is an important duty. It
usually targets on resources which support the internal end users. Therefore, the network
monitoring system has developed to manage wide range of devices such as cell phones, servers,
routers and switches. Several network monitoring systems come with an automatic detection that
able those to record devices continuously when they are added, deleted or undergo configuration
changes.

6. 2.3 Comparisons of Previous System 1, 2, 3
System 1
Figure 1.0 Internet Monitoring System
The Figure 1.0above shows an Internet Monitoring System for a small organization.This
system includes few main functions such as Pinging Address Range, Trace Route, Network
Status and other minor functions such as IP Configuration, Routing table and Network
Calculator. The advantage of this system is that it consists of Alarms function that notifies the
network administrator if there is a suspicious packet or IP Address is detected.
This will save the administrator time for having to look at the system activities frequently for
the traces of any threats. Besides that, this system also has a help function which enables users to
understand about the function if they are confuse with the procedures and functions regarding the
system. However, this system does not have an attractive Graphical User Interface which will
make users bored using the system. In addition, this system lacks in security. It allows anyone to
access without any secure authorization into the system. This will lead to big problems such as
data lost or even data corruption due to cyber theft.

7. System 2
Figure 2.0Monitoring System
The Figure2.0 above shows a Monitoring System for a large organization. This system includes
functions such as Pinging Address Range, SNMP, Network Status and other minor functions
such as IP Configuration, Routing table and history logs. The advantage of this system is that it
consists of history logs which enable admin users to record or see the previous data. They can
also store old configuration and recover them if they accidently deleted. The disadvantages of
this system are network administrator will not be able to identify the function because it only
consists of icons without labels. This will be difficult for the administrator if they are in a hurry.
Besides that, the Graphical User Interface is too congested and complicated to look at.

8. System 3
Figure 3.0 Network Monitoring Analyzer
Figure 3.0 above shows a Network Monitoring Analyzer. This system monitors the upload and
downloads speed of the organization. It shows in detail about the speed of each activities being
run in the system. Moreover, there is an icon which can save the current statistics of bandwidth.
The disadvantage of this system is that it does not have many functions. Besides that, this system
is very light and doesn’t have enough functions on it.

9. 2.4 Previous SystemsvsLan Monitoring System
The researcher’s system consist of few core functions such as file transfer, upload and download
speed tracking, monitoring RAM and CPU usage and pinging each of the computers in a same
Lan network. Unlike other systems, the researcher’s system is not only able to monitor but it also
kills unwanted processes of otherpc. Besides that, the system is also secured with login a
password that allows only the network administrator to access it. This is one of the advantages of
the researcher’s system. Moreover, researches system is able to switch on and off a particular
user’s computer if the user is not using it or the user is misusing it. This way the organization’s
productivity and also the security of the system are being maintained. In addition, the
researcher’s system has a function similar to system 2 which is the log history where the
administrator user can record and recover monitored data.

10. Chapter 3: Methodology
3.1 System Development Methodology (SDM)
System development is also known as suggested compilation of techniques, procedures,
documentation, rules and tools for developing information system. The definition of stages or
processes in developing a system is obtained from system development methodologies.
Adding on, structuring, planning and controlling the processors in developing the software with
different strength, weakness and approach can be produced by this system development
methodology. Furthermore system development methodologies are formed to correct any form of
concerns in the project, which also lessens the possibility of project breakdown, where for an
example it makes sure that all project team members are operating in the same direction to avoid
any misunderstanding. The frequently considered methodology approaches such as iterative, plan
driven or agile approach are needed when the software engineer develops a system.
3.2 Benefits of SDM
 Provide performances, key deliverables and to evade confusion or misplaced duty.
 Simplifying tasks and reducing training are involved in the consistency of project
development.
 Making sure all members are striving for the same target.
 The efficiency in analysis and reporting will be helpful under the methodology.
 Reducing cost, increasing efficiency and a more solid management of project schedule can
decrease the chances of project failure.

11. 3.3 System Development Life Cycle (SDLC)
The common methodology in developing a system is called Information System Development
Life Cycle and as well identified as the system Development Life Cycle. The common approach
to develop software projects and also an influence to other methodology is the SDLC which is
the essential of various system development projects.Moreover, standard or typical system
analysis model are widely also known as the SDLC stages. Adding on, the majority of the
deviation will have the fundamental arrangement of creating a system, but recently the SDLC
has various alternatives increasingly. The SDLC has many variants over the years, but most of
the variants will have the basic structure of developing a system.
The table below shows the segments of the vital composition of the development processors in
the SDLC:
 Feasibility Study
 System Investigation
 System Analysis
 System Design
 Implementation
 Review and Maintained
The linear approach or structure in establishing a system is also categorized under the SDLC.
Basically, creating a system into series of phases and offering an approach as a principle in
software development is also a divided methodology process. In enhancing the aim of the project
that it should be well handled and the quality product is generated, the scheduling and usage of
documentation principles are underlined on the SDLC model.

Based on the all the research above, researcher will like to conclude that this system is a
very good system because lots of research has be done by the researcher on this system.
Researcher has also chosen three existing Network Monitoring System in the market and has
compared it with this Lan Monitoring System. Many weaknesses have been found out from the
previous system and lots of modifications of the previous system have been implemented in
researcher’s Lan Monitoring System. Besides that there are some development techniques to
follow to implement a good and reliable system for the users. Researcher will be using System
Development Life Cycle as a methodology. This methodology chosen is a good technique to be
followed because the stages and process in this method is very useful and easy for the developer
to develop the system.
Researcher has even collected lots of info on programming language to see which
programming language is really suitable to program this Lan Monitoring System. Researcher has
also compared with few other programming languages and decided to come up with a good
conclusion. Researcher chose C# as Programming Language to be implemented in this Lan
Monitoring System.
Last but not least, researcher has chosen Extensible Markup Language has a database of
LMS. More over for the Analysis section, researcher will program out a system based on the
questionnaire that users answered and based on user requirements. Furthermore, researcher used
UML modeling language to describe the system in different kind of diagram forms such as Use
Case Diagram, Activity Diagram and Sequential Diagram. Researcher also has sketched few
diagrams of Graphical User Interface of the Lan Monitoring System and on how probably the
system will look like.
As a conclusion, based on the documentation and all the research that researcher has
done, Researcher will create a very good system called LAN Monitoring System (LMS).
