| description | Low quality connection is a situation when the level of availability of
system resources is not able to provide QoS requirements of Internet application.
These conditions in turn affect the quality of access services received by users.
Many efforts to resolve the Internet access problem by focusing on the objective
QoS to improve the performance of the systems/network have been initiated then.
In fact, the approach with the objective QoS is still not able to resolve the problem
of Internet access in the low quality connection as most Internet applications are
developed with an assumption that all systems already have high-speed
connection. The problem appears as when the system could not fulfill the needs of
QoS application, the application will decide to fail the operation without leaving
the users any options. As a result, it is extremely difficult to execute a complete
access operation in a low-quality Internet connection. This situation discourages
people from harnessing the potential of Internet as a communication medium or a
giant information repository.
One approach to solve the problem is by providing the users more flexibility
in controlling access behavior. It is then becoming necessary to replace the fixed
default behavior with configurable settings representing dynamic behavior. For
this reason, the paradigm or perspective used in this study differs from existing
researches. While in the previous studies, the reviews were taken from the
perspective of Objective QoS, this research is focused on subjective QoS as the
basis for the fulfillment of user QoS. The determination of subjective QoS is for
the fulfillment of user in accessing preferences on low quality connection.
This research is concerned with the study of mechanism for the provision of
QoS guarantees for Internet access in low-quality connection. It describes the
design and implementation of QoS framework, a QoS architecture for user�s QoS
specification and service enforcement that is designed to solve the limited Internet
access in unreliable Internet connection. The framework supports a dynamic
access model that provides users more flexibility in controlling access behavior.
The most essential part of this research is how to turn the pattern of default access
into the more dynamic one leading the users to have flexibility in controlling the
access pattern based on preference and provision. Responding this point, a
mechanism for the users to express the preference of subjective QoS and
mechanism that can change the pattern of access application based on the
specification of the users of provision of resource are needed. Hence there is a
need to develop the framework of the user-oriented QoS that supports the model
of dynamic access and provides flexibility for the users in controlling the access
behavior.
The framework of the user-oriented QoS in addition provides an option for
user in doing an access if resource availability of the system is limited. The users
are given opportunity to specify their subjective preferences and determine the
parameter for each chosen application. The system will check the resource
availability and then compares it to the user preferences. The system in the case
where resource availability is lower than user preferences can provide other
options for access according to the access specification determined by the users.
This research also presents a prototype implementation of the QoS
framework and the use of QoS framework in several application scenarios running
in low-quality connection environment. Implementation of QoS framework on
Internet applications and a series of tests show that the mechanism of specification
and determination of user access services allow the application behavior to be
controlled according to conditions of low-quality connection and subjective QoS
requirements of users. |
