In this paper, the authors develop a comprehensive framework for QoS management based on soft probabilistic contracts. The authors approach also encompasses general QoS parameters, with “response time” as a particular case. In addition, the authors support composite QoS parameters, for example, combining timing aspects with “quality of data” or security level. They also study contract compositi...

this research has studied and ranked the service quality and its relation with customers' satisfaction in a bank in iran. in the theoretical principles section, the concepts and denitions related to services, satisfaction, banking and research background have been studied. the statistical community of the study was all the bank customers that have referred to the bankand have had interest...

Research reported in this paper deals with a communication architecture with guaranteed end-to-end Quality of Service (QoS) in an IPv6 environment providing differentiated services within a single Diff-Serv domain. The page successively presents the design principles and services of the proposed architecture, their implementation and finally experimental measurements evaluating the QoS availabl...

Quality of Service (Qos) plays a key role in web services. In an open and volatile environment, services may not deliver the Qos they declared. Hence, it is important to provide a Qos assessment model to select the most appropriate service for the user. Although many researches have been done to develop models and techniques to assist users in Qos assessment, most of them ignore various Qos req...

This paper presents a dynamic hybrid Service Overlay Network (SON) for service composition for multimedia delivery in mobile networks. The overlay considers the nomadic nature of mobile nodes in the decision for node placement within the overlay as well as the types of services provided and expected Quality of Service (QoS) levels. Dynamic re-organization of the overlay reflects changes in stab...

We extend the service abstraction in the Open Grid Services Architecture[12] for Quality of Service (QoS) properties. The realization of QoS often requires mechanisms such as advance or on-demand reservation of resources, varying in type and implementation, and independently controlled and monitored. Foster et al. propose the GARA [10] architecture. The GARA library provides a restricted repres...

Quality of service (QoS) is playing a vital role in communications system in emerging technologies. QoS means providing consistent and predictable data delivery service. QoS is dealt with providing real-time as well as non-real-time services. In this paper swarm based handover approach is proposed in UMTS /WLAN technologies. The proposed approach is used to evaluate the QoS Characteristics. The...

In this work the Service abstraction is extended to support Quality of Service (QoS) attributes – and implemented in the Grid QoS Management (G-QoSM) framework. The framework supports three main functions: (1) providing mechanisms for establishing QoS guarantees via Service Level Agreements (SLAs), (2) enabling QoS management on allocated QoS-aware services, and (3) supporting discovery of serv...
