A Comparative Model for Tradeoff Analysis of QoS Attributes in SOA

چکیده
It is inadequate to just assure the functional requirements. Quality of service (QoS) must also be satisfied. An important challenge for developing efficient Service Oriented Architecture (SOA) is to maintain the QoS attributes because of compositional and dynamical environment of SOA. It is significant to scrutinize how quality attributes are supported by SOA. However, implementation of SOA presents complex challenges to achieve preferred QoS objectives. Developing the efficient ways to integrate the quality of service attributes with system’s architecture offers a basis to take decision regarding trade-off. This paper proposes a comparative model to analyze the trade off among the QoS attributes in SOA. Our major goal is to trade off among the various QoS attributes to achieve an improved system as a whole because it is unrealistic to achieve the full set of QoS requirements in any particular domain.

Measuring the Efficiency of Financial Cloud Services in the Banking Industry Using the Modified Dynamic DEA with Network Structure: The Case of Iran E-Banking
Nowadays, the great benefits of cloud computing have dramatically increased the number of e-banking users. Hence, the competition in the banking industry has boosted and managers need to evaluate their branches on a regular basis. To this end, this study aims to evaluate cloud-based banking systems based on the Quality of Service (QoS) attributes using the Dynamic Network Data Envelopment Analy...
متن کاملAdvanced operations research techniques for multi-constraint QoS routing in internet
Internet Traffic has grown exponentially over last few years due to provision of multiple class services through Internet backbone. With the explosive use of Internet, contemporary Internet routers are susceptible to overloads and their services deteriorate drastically and often cause denial of services. In this paper, an analysis is made how forecasting technique, routing algorithm and Genetic...
متن کاملImproving Success Ratio in Multi-Constraint Quality of Service Routing
Multi-constraint quality-of-service routing will become increasingly important as the Internet evolves to support real-time services. It is well known however, that optimum multi-constraint QoS routing is computationally complex, and for this reason various heuristics have been proposed for routing in practical situations. Among these methods, those that use a single mixed metric are the mo...

The purpose of this paper is to present the possibility of replacing physical unit cost in transportation or distribution problems by an aggregate coefficient, getting qualitative and subjective considerations involved. The model for constructing aggregate cost is a two stage multiple attribute decision-making problems. In the first stage supply points, demand points and routes of transportatio...

In this paper we describe SOAROAD (SOA Related Ontology of Architectural Decisions), which was developed to support evaluation of architectures of information systems using SOA technologies. The main goal of the ontology is to provide constructs for documenting service-oriented architectures, however, it is designed to support future reasoning. Building the ontology we focused on the requiremen...
