Quality of Service (QoS) is one of the most important and active research topics within Grid technology. But the emerging transformation from a product oriented economy to a service oriented economy establishes a new scenario where actual QoS mechanisms need to be enforced and new QoS mechanisms needed. Service Level Agreements (SLAs) are considered the cornerstone born to fulfill those require...

A lot of attention has been given to network quality of service and efforts to make layers on top of the network also QoS-aware increase noticeably. This paper explores QoS-aware service provisioning at a level close to end-user’s perception. It shows how end-user oriented QoS requirements have been elaborated in a high level design onto QoS support of a distributed service platform and how rea...

Recently, quality-of-service routing in dynamic, wireless multi-hop ad hoc networks becomes a hot research topic, and various QoS protocols are proposed Even so, popular QoS routing protocols rarely provide multiple routes. Once links break due to node mobility, establishment of new routes leads to large control overhead and more end-to-end delay. In MANETs to support multimedia applications su...

Service integrated communication systems need to serve concurrently a variety of applications, probably each of them with diierent service requirements. Therefore, an integrated Quality-of-Service (QoS) management is needed. Within this paper, a exible approach of QoS management in high performance networks is presented. QoS management functions can be conngured in order to build a service-tail...

Current Internet is not able to deploy advanced end-to-end services to support new applications, like interactive multimedia. The best effort service, supported by the Internet, does not offer Quality of Service (QoS) performance guarantees to these applications. Although technology for providing QoS-based services inside domains (networks) is available, the challenge is how domains should inte...

Web service technology offers facilities for business process automation. However, Business Process Management Systems (BPMSs) demand additional facilities. For instance, there is no Quality of Service (QoS) management support in the current Web service model. The goal of this paper is to propose a policy-based Web service infrastructure, which offers autonomic service integration using QoS att...

Forthcoming applications, especially distributed multimedia and interactive applications, have stringent requirements on the quality of the communication service. Therefore, an integrated Quality-of-Service (QoS) management is needed including all involved components to guarantee a communication service from application to application. One promising approach to guarantee a certain level of serv...

Quality of Service (QoS) has become an increasingly important concept in wide-area distributed systems. The overall QoS characteristics of a wide-area distributed system are influenced by the QoS of the individual hosts involved and the QoS of the communication subsystem connecting these hosts. In this paper, we include a general presentation of wide-area computing and Quality of Service concep...

-------------------------------------------------------ABSTRACT------------------------------------------------------------In this era of Cloud Computing and Service Architecture, it is expected that web services will proliferate the current market and business will expose their web service’s as B2B, C2B, E2E and C2C service componets, many web services offer the similar services, and the clien...

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...
