SHReQ: A Framework for Coordinating Application Level QoS
نویسندگان
چکیده
We present SHReQ, a formal framework for specifying systems that handles abstract high-level QoS aspects which are becoming more and more important for service oriented computing. SHReQ combines Synchronised Hyperedge Replacement (SHR) with constraint-semirings. SHR is a (hyper)graph rewriting mechanism for modelling mobility and reconfiguration of systems. The novelty of the approach relies on the fact that constraint-semirings provide both the mathematics for multi-criteria QoS and the synchronisation policies underlying the SHR mechanism.

A Framework for QoS Guarantees for Multimedia Applications within an Endsystem
We describe a framework for providing quality-of-service guarantees within the endsystem for networked multimedia applications. Our framework integrates four components namely, QoS speciication, QoS mapping, QoS enforcement, and a protocol implementation model. The framework allows QoS speciications to be at a high level so that an application can easily specify its requirements using a small n...
متن کاملA Reflective QoS-enabled Load Management Framework for Component-Based Middleware
A new reflective QoS-enabled load management framework for component oriented middleware is presented. The proposed framework offers the possibility of automatically selecting the optimal load distribution algorithms and changing the used load metrics at runtime, according to workload time evolution. QoS service level agreements are being offered at application level, transparent to the managed...
متن کاملAggregated QoS Mapping Framework for Relative Service Differentiation-Aware Video Streaming
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 ...
متن کاملNovel Methods For Determining QoS Parameters and Thresholds in End User's Service Level Agreement
Service level agreement (SLA) is a powerful tool to formalize the negotiation and agreement between the service provider and service seeker with the scope of service quality characteristics, compensations and tariffs. The service quality description is the main part of a SLA which can be characterized by the use of suitable and feasible quality of service (QoS) parameters. Determining suitable ...
متن کاملA Cross-layer QoS-Supporting Framework for Multimedia Delivery over Wireless Internet
This paper presents a framework, which provides QoS (Quality of Service) support, for multimedia delivery over wireless Internet with cross-layer architecture. In this framework, we address the important issues for multiple media, such as audio, video, email, and web traffic, transmitted over wireless Internet. In order to have efficient QoS support for different types of media, we propose a cr...
