Quality of Service (QoS) guarantees for delay sensitive networked mul-timedia applications, such as teleoperation, must be application-to-application. We describe a set of services, a service kernel, required at the end points, for multimedia call establishment with QoS guarantees. These services provide: (1) Translation among diierent domain speciications (layer-to-layer translation) and domai...

Effective and efficient Quality of Service (QoS) management is critical for a service grid to meet the requirements of both grid users and service providers. We incorporate QoS management into Open Grid Services Architecture (OGSA) and provide a high-level middleware to build complex applications with QoS guarantees. We introduce a scalable framework of information service in which capabilities...

Web Services are the interoperable and loosely coupled components for simplifying business processes over the web and are popular model of distributed computing now a days. There are a very few datasets available regarding Quality of Service (QoS) for web services since web services datasets are difficult to create. The reason being that it requires more effort to collect service information fr...

4G Communication Networks provide heterogeneous wireless technologies to mobile subscribers through IP based networks and users can avail high speed access while roaming across multiple wireless channels; possible by an organized way to manage the Quality of Service (QoS) functionalities in these networks. This paper proposes the idea of developing a novel QoS optimization architecture that wil...

Enterprise systems should be assembled out of components and services according to an orchestration schema and taking into account not only functional requirements but also the resulting Quality of Service (QoS). In other words, QoS-aware composition of services and components must be performed. The problem is to find which components or services have to be employed that the resulting system wo...

Service composition is popular for composing a set of existing services to provide complex services. With the increasing number of services deployed in cloud computing environments, many service providers have started to offer candidate services with equivalent functionality but different Quality of Service (QoS) levels. Therefore, QoS-aware service composition has drawn extensive attention. Mo...

Determining the QoS (quality of service) of composite Web services is of high importance for both service providers and service consumers. Heterogeneity of service descriptions, however, often hinders the aggregation of QoS parameters. We propose ontology-based QoS aggregation that integrates the semantics of QoS parameters and their aggregation into the overall aggregation process. The contrib...

The majority of today’s Internet-based services are generally not concerned about the level of Quality of Service (QoS) presented to their users. For many such services, however, the QoS perceived by users is becoming a critical success factor. The main QoS attributes include those related to the service availability and timeliness. Ensuring them is essential to many services. In our opinion, t...

A novel and simple approach for defining end-to-end quality of service (QoS) in video-on-demand (VoD) services is presented. Using this approach, we derive a schedulable region for a video server which guarantees end-to-end QoS, where a specific QoS required in the video client translates into a QoS specification for the video server. Our methodology is based on a generic model for VoD services...

Today’s mobile data applications aspire to deliver services to a user anywhere anytime while fulfilling his Quality of Service (QoS) requirements. However, the success of the service delivery heavily relies on the QoS offered by the underlying networks. As the services operate in a heterogeneous networking environment, we argue that the generic information about the networks’ offered-QoS may en...
