The QoS (quality of service) of a service product perceived by the end-user depends on the performance achieved by the components that constitute that product as well as performance of the network and service resources on which those components run. These resources may be spread over many domains and owned by different network and service providers. In this scenario, the end-toend QoS will depe...

Describing service quality from the end-users' point of view is fulfilled by using Quality of Experience (QoE) metrics. In a networking environment QoE metrics are very close to Quality of Service (QoS), but – because of the subjective nature of QoE – they could not be derived directly from QoS. Collection and analysis of QoS and SLS (Service Level Specification) properties of networking servic...

For applications relying on the transfer of multimedia, and in particular continuous media, it is essential that quality of service (QoS) is guaranteed system-wide, including end-systems, communications systems and networks. Although researchers have addressed many isolated areas of QoS provision, little attention has so far been paid to the definition of an integrated and coherent framework th...

In the early service transactions, quality of service (QoS) information was published by service provider which was not always true and credible. For better verification the trust of the QoS information was provided by the Web service. In this paper, the factual QoS running data are collected by our WS-QoS measurement tool; based on these objectivity data, an algorithm compares the difference o...

An Ad-hoc network has a Provision of Quality of Service (QoS) to support many applications like digital and multimedia applications. However, one of the challenging tasks in Ad-hoc Network (MANET &VANET) is Quality of Service (QoS) which is determined by numerous parameters such as bandwidth and delay constraints, varying channel conditions, power limitations, node mobility, dynamic topology, p...

Abstract: This paper presents an QoS (quality of service) based control system of teleoperation via the Internet. Quality of service on the Internet refers to a set of quality requirements on the performance of the data transmission necessary to achieve the required functionality of an application. The quality of data transmission via the Internet is measured or reflected by a set of QoS parame...

An Ad-hoc network has a Provision of Quality of Service(QoS) to support multimedia applications. One of the most challenging tasks in Ad-hoc Network(MANET &VANET) is Quality of Service (QoS) which is determined by numerous parameters such as bandwidth and delay constraints, varying channel conditions, power limitations, node mobility,dynamic topology, packet delivery ratio, end-to-end delay and...

User perception of a networking service is usually very different from the operators’ understanding of service usability. Quality of Experience (QoE) metrics are supposed to describe the service from the end-users’ point of view – although QoE is hard to measure for mass services. Collection and analysis of QoS and SLS (Service Level Specification) properties of networking services are daily ta...

In wireless environment, the periodic moments of wireless networks may cause the fluctuation of available bandwidth by varying with time and location. The periodic fluctuation disturbs the resource distribution and Quality of Service (QoS). Qos design is the fundamental functionality of the networking router to enable differentiated delivery and to guarantee the delivery quality for different s...
