Grid computing provides a robust paradigm to aggregate disparate resources in a secure and controlled environment. Grid architectures require an underpinning Quality of Service (QoS) support in order to manage complex data and computation intensive applications. However, QoS guarantees in the Grid context have not been given the attention they merit. In order to enhance the functionality offere...

In an open and dynamic cloud computing environment, the randomness of cloud services with unreliable quality leads to low accuracy in service composition. To address the above problem, this paper proposes a global trust service composition approach based on random QoS and trust evaluation, considering the multi-criteria assessment of service quality. Firstly, statistical test is employed to rem...

Quality of service (QoS) support that provides customized service qualities to multiple classes of client requests can effectively utilize available system resources. This paper presents the design and implementation of a flexible and efficient QoS framework for cluster-based network services. This framework achieves four objectives. First, the framework provides a flexible mechanism for servic...

In this paper we present a detailed review on the Trader’s Quality of Service (QoS) Specifications and the Effects on System Performance for Video-on-Demand Multimedia (MM) Applications, based on server-fault initiated session switch. Enhanced Trader lists the resources necessary to support the application’s QoS requirements and makes them available for the Session Manager, which co-ordinates t...

This research investigates the Quality of Service (QoS) interaction at the edge of differentiated service (DiffServ) domain, denoted by video gateway (VG). VG is responsible for coordinating the QoS mapping between video applications and DiffServ enabled network. To accomplish the goal of achieving economical and high-quality end-to-end video streaming, which utilizes its awareness of relative ...

The wireless networks are experiencing higher delay, higher error rate, and lower bandwidth compared to wired networks. The customers not only need mobility but also quality. It is a great challenge for the service providers to offer Quality of Service (QoS). The QoS parameters are divided into two categories such as Qualitative QoS parameters (reliability, security, etc.) and Quantitative QoS ...

Quality of Service (QoS) provisioning is one of critical issues in the wireless and mobile network. However, the existing works for QoS guarantee focused on only the wireless network characteristics. In this paper, we proposed an end-to-end QoS provisioning architecture in the diverse mobility situations. This architecture consists the Differentiated Service (DiffServ) model and Integrated Serv...

Due to the increasing growth of Web Services, Quality of Service (QoS) is becoming a key issue in web services community. Providers and clients need to use QoS-aware architectures to get/ensure end-to-end QoS. The QoS delivery to clients is highly affected by the web service performance itself, by the hosting platform (e.g., Application Server) and by the underlying network (e.g., Internet). Th...
