Context: Nowadays one of the most beneficial business in IT area is web services with huge amount of users. The key ofsuccess in these type of services is flexibility in terms of providing same quality of services (QoS) and ability of fasttroubleshooting when number of users increase rapidly. To achieve these targets, evaluation of the user satisfaction is highlyessential. Moreover it is required to link user dissatisfaction to QoS parameters in terms of troubleshooting. Objectives: The main aim the research is to find an intelligent method for evaluation of the user satisfaction. The method i

Abstract:
The focus of this thesis has been on Quality of Service (QoS) and Qualityof Experience (QoE) dimensions of adaptive video streaming. By carryingout a literature study reviewing the state of the art on QoS andQoE we have proposed several quality metrics applicable to adaptivevideo streaming, amongst them: initial buffering time, mean duration of arebuffering event, rebuffering frequency, quality transitions and bitrate. Perhapscounterintuitively, other research has found that a higher bitratedoes not always lead to a higher degree of QoE. If one look at bitrate inrelation to quality transitions

Abstract:
Smartphones have become crucial enablers for users to exploit online services such as learning, leisure, communicating, and socializing. The user-perceived quality of applications and services is an important factor to consider, in order to achieve lean resource management, to prevent user churn and revenue depletion of service or network providers. This is often studied within the scope of Quality of Experience (QoE), which has attracted researchers both in academia and industry. The objective of this thesis is to study the most important factors influencing QoE on smartphones and synthesize

Abstract:
With the development of mobile web services, it is important to know for a service provider how Quality of Service (QoS) is related with the Quality of Experience (QoE) for the mobile users. Any change in the QoS could be reflected on the QoE. However, good QoS does not always provide good QoE. Thus, a proper combination of QoS and QoE results in a good user experience. Good understanding of QoS and QoE is necessary in order to achieve that. In addition, identifying the proper relationship between network level QoS and user-end QoE is extremely challenging task which requires the highest level

Abstract:
Networked Control Systems (NCS) are distributed control systems where the sensor signals to the controllers and the control data to the actuators are enclosed in messages and sent over a communication network. On the one hand, the design of an NCS requires ensuring the stability of the control system and achieving system response that is as close as possible to that of an ideal system which demands network resources. On the other hand, these resources are limited and have to be allocated efficiently to accommodate for future system extensions as well as applications other than control purpose.

La navigation Web est l'un des principaux services de l’Internet où un large éventail d'acteurs est impliqué et évolue de manière constante. Les nouveaux protocoles de l’Internet, les réseaux de diffusion de contenu (CDN) ou encore les évolutions des différents navigateurs Web sont destinés à améliorer les temps de chargement des pages. Pour mieux comprendre la Qualité d'Expérience (QoE) perçue par les utilisateurs, il est donc essentiel d’identifier comment le contenu des pages est constitué et délivré et de fournir une métrique de QoE pertinente.

Abstract:
The constantly increasing amount of video traffic is a challenge for service providers that need to maximize Quality of Experience (QoE) while optimizing the cost of their infrastructure. In this thesis, we address the problem of routing multiple HTTP-based Adaptive Streaming (HAS) sessions to maximize QoE. We first design a model linking the Quality of Service (QoS) Metrics to a single QoE score. This QoS-QoE model incorporates different QoE metrics and is able to learn online network variations and predict their impact on representative classes of adaptation logic, video motion and client re

Abstract:
In the Internet of today there is a demand for both high bandwidth and low delays. Bandwidth-heavy applications such as large downloads or video streaming compete with more delay-sensitive applications; web-browsing, VoIP and video games. These applications represent a growing share of Internet traffic. Buffers are an essential part of network equipment. They prevent packet loss and help maintain hight throughput. As bandwidths have increased so have the buffer sizes. In some cases way to much. This, and the fact that Active Queue Management (AQM) is seldom implemented, has given rise to a phe

Cette thèse présente un ensemble de solutions qui contribuent à la proposition et la réalisation d’une telle approche.

Abstract:
Voice over Internet Protocol (VoIP) has become a key technology of communication. Our work has been a practical implemenation of different scenarios to show that VoIP voice quality can be improved by adopting certain Quality of Service(QoS) measures such as classification, marking or queuing. It has been discussed that different QoS metrics like delay, packet loss and jitter could affect the voice quality of VoIP. To reduce the negative affects, one option is to implement certain QoS mechanisms with some set of configurations. For this purpose, Cisco IP phones have been configured in our topol

Ever since the excavation of the Shuihudi (in Chinese 睡虎地), we now know in Qin, there was the Rule Book of Implementation 《行書》律(about the laws on documentation systems). Unfortunately, there was no correspondence for cross examination. Not until the excavation of the Liye (里耶) site in 2002 were we able to identify the format of the correspondence between the central government, provinces and towns.

Bluetooth is a low cost, short-range radio technology that enables electronic devices to communicate wirelessly via ad-hoc networks. Different kinds of applications may run over these networks, some of these applications with particular Quality of Service (QoS) requirements. One such application could for instance be an Audio application which need data frames to be delivered at regular interval to work properly. The communication over Bluetooth links is totally controlled by one of the participating nodes. Since this node controls the traffic and thereby controls the QoS within the network it
