Towards a QoS Modeling and Modularization Framework for Component-based Systems

Sumant Tambe, Akshay Dabholkar, Aniruddha Gokhale, Amogh Kavimandan
2008 2008 12th Enterprise Distributed Object Computing Conference Workshops  
Current domain-specific modeling (DSM) frameworks for designing component-based systems provide modeling support for system's structural as well as non-functional or quality of service (QoS) concerns.  ...  This paper describes Component QoS Modeling Language (CQML), which is a reusable, extensible, and platform-independent QoS modeling language that provides strong separation between the structural and nonfunctional  ...  OMG has also adopted a more general profile for modeling QoS [13] . This UML profile provides a way to specify the QoS ontology with QoS characteristics.  ...

QoS-Based Service Provision Schemes and Plan Durability in Service Composition [chapter]

Koramit Pichanaharee, Twittie Senivongse
2008 Lecture Notes in Computer Science  
service gives a special class of QoS when they operate in the same plan.  ...  We also address that it is desirable for service planning to result in a plan that is durable and reusable since change in the plan, e.g. by deviation of the actual QoS, would incur overheads.  ...  The work in [11] introduces a model-driven methodology for building QoS-optimised composite services and uses UML profile for QoS to model QoS requirements.  ...

2005 Lecture Notes in Computer Science  
In this work, we define a profile for reliability analysis by extending the UML 2.0 specification to support reliability prediction based on scenario specifications.  ...  Recently, the UML Profile for Modeling Quality of Service has defined a set of UML extensions to represent dependability concerns (including reliability) and other non-functional requirements in early  ...  Vittorio Cortellessa provided several valuable comments that improved our understanding of reliability modeling in UML and the state of current efforts with relevant UML profiles.  ...

Reliability Support for the Model Driven Architecture [chapter]

Genaína Nunes Rodrigues, Graham Roberts, Wolfgang Emmerich
2004 Lecture Notes in Computer Science  
The novel contribution of this paper is to provide a means to support reliability design following the principles of the Model Driven Architecture(MDA).  ...  Quantifying dependability in terms of reliability can be carried out by measuring the continuous delivery of a correct service or, equivalently, the mean time to failure.  ...  Acknowledgment We would like to thank Rami Bahsoon and Licia Capra for assisting in the review of this document.  ...

A Study on the Effect of Application and Resource Characteristics on the QoS in Service Provisioning Environments

Theodora Varvarigou, Konstantinos Tserpes, Dimosthenis Kyriazis, Fabrizio Silvestri, Nikolaos Psimogiannos
2010 International Journal of Distributed Systems and Technologies  
Thus, we create a simple modeling scheme for describing in a unique way the resource and the application characteristics with regards to the QoS.  ...  For example, in a 3D rendering application service, a service provider would have to ensure that the processor that will undertake the task to render 100 frames will be able to do so in 3 seconds because  ...  In the first step, a resource demand estimation scheme is implemented through a profiling process. Profiling creates detailed resource profiles of each component in the application.  ...
