چکیده
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 computationand data-intensive applications. However, QoS guarantees in the Grid context have not been given the importance they merit. In order to enhance the functionality offered by computational Grids, we overlay the Grid framework with an advanced QoS architecture, called G-QoSM. The G-QoSM framework provides a new service-oriented QoS management model that leverages from the Open Grid Service Architecture (OGSA) and has a number of interesting features: 1) Grid service discovery based on QoS attributes, 2) policy-based admission control for advance reservation support, and 3) Grid service execution with QoS constraints. This paper discusses the different components of the G-QoSM framework and presents an initial prototype implementation.

متن کاملApplying the reflective middleware approach in Grid computing
Significant progress has been made in the design and development of objectbased distributed systems and, more recently, in component-based reflective middleware platforms—i.e., middleware platforms that, through reflection, can be flexibly configured, and run-time adapted/ reconfigured—especially in terms of non-functional properties like quality of service (QoS). In this paper we consider how ...
متن کاملAn Experience Report on Designing and Building OGSA-DQP: A Service Based Distributed Query Processor for the Grid
OGSA-DQP is a distributed query processor exposed to users as an OGSA-compliant Grid service. This service supports the compilation and evaluation of queries that combine data obtained from multiple services on the Grid, including Grid Database Services (GDSs) provided by OGSA-DAI project. Not only does OGSA-DQP support integrated access to multiple Grid services, it is itself implemented as a ...
متن کاملMG-QoS: QoS-Based Resource Discovery in Manufacturing Grid
The emerging of the Open Grid Service Architecture (OGSA) andGT3 provides a solution to Network ManufacturingManufacturing Grid (MG). We apply GT3 to manufacturing by developing a MG Quality of Service (MG-QoS) management system. The main focus of this framework is to provide a means for the users to search for services based on QoS criteria in Manufacturing Grid, to provide QoS guarantees for ...
متن کاملTowards a Market-Centric OGSA-Compliant Architecture Model
The Open Grid Services Architecture (OGSA) provides a high-level framework for service-oriented grid architecture, mostly based on web service standards. The vision of a worldwide computing grid evokes the scenario of electronic markets for grid services. The object of our investigation is a serviceoriented grid architecture model that is compliant with the OGSA specification. We address the pr...
