CHAPTER III: RESEARCH METHODOLOGYAND ANALYSIS OF
MULTIMEDIA SERVICES
III.1 Introduction
A methodology is a series of choices such us choices about
what information and data to gather, Choices about how to analyze the
information and data that you gather and other methodological choices. In This
project the choice made is the one that helped to analyze the network by making
comparison and it is called a comparative research methodology.
Comparative methodology is the act of comparing two or more
things with a view to discovering something about one or all of the things
being compared. This technique often utilizes multiple disciplines in one
study.
When it comes to method, the majority agreement is that there
is no methodology peculiar to comparative research. The multidisciplinary
approach is good for the flexibility it offers, yet comparative programs do
have a case to answer against the call that their research lacks a
«seamless whole». 23In this case the comparison was done
between traditional streaming and IP packet charging models in a network.
III.2 Section approach
This section presents a methodology evaluation framework
within which the methodology comparison is conducted. This framework consists
of a series of questions used to identify and quantify a methodology's support
for a specific development process. The framework employed considers four major
areas ofeach methodology:
· Concepts
· Notations
· Process
· Pragmatics

III.2.1 Concepts
This section cites from the particular method and then
contrasts support for terms within each method under scrutiny i.e. this section
is the theoretical concepts that have been used in this work.
III.2.2 Notations
Many methods require the creating of abstract descriptions,
or graphical models, of the system under analysis and/or design. In this study,
the system under analysis are traditional streaming and IP packet charging
model for multimedia services i.e. result that has been found by testing the
network performance and quick relay of both traditional streaming and IP packet
charging model for multimedia services have been compared in order to get the
advantages and disadvantages of the above systems
III.2.3 Process
The process component of this comparison is used to
characterize within what development contexts the method is appropriate, how
much of the systems analysis is covered by the methodology used.
III.2.4 Pragmatics
This section considers the pragmatics ofthe methodology. A
methodology's pragmatics consists of:
· Resources
· Required Expertise
· Accessibility
· Domain Applicability
III.3 Live media model Analysis
This part of the project focuses on making comparison between
traditional live streaming and packets charging model for multimedia services.
When comparing both traditional live streaming and packets charging model for
multimedia services, there are some factors that will be take in consideration
such as bandwidth, latency, jitter and so on.
After doing comparison, the comparison table between
traditional live streaming and packets charging model will e needed in order to
show the differences between them according their behavior inside the
network.
