The growth of different types of applications in the Internet arises the need for supporting Quality of Service (QoS) for them. Differentiating services aims to differentiate among applications in order to provide their requirements based on the level of QoS they need and their characteristics. In this paper we introduce a dynamic QoS-Aware queuing algorithm to differentiate services in IP basednetworks,...
In this paper, the fuzzy logic-based decision algorithm is proposed for queue scheduling. This algorithm is employed to determine the optimal values for achieving fairness control for each queue-type serviced. It takes into account the dynamic nature of the internet traffic as regards to its time-varying packet arrival process that affects the network states and performance. In order that the fairness...
The influence of the uncertain or malicious service nodes on the Web service composition (WSC) performance is generally fatal in the Internet, so the problems of services selecting for WSC can not be completely solved by the perspective of performance. In the paper, the two-tier model of reputation computing, which describes the credibility evolution mechanism of the inter-entity relations in the...
With the development of the Grid computing, increased attention is paid to services and user personalization. How to search and schedule the most suitable service for an end user direct affects the popularization use of service oriented Grid. Inspired from the mode of web search engine, such as Yahoo, Google, this paper proposes an innovative service searching and scheduling algorithm (SPSE: Service...
The quality of services is one of the most important issues of today's internet. The programs and the different internet users' quality of services are different from one another. Varieties of methods have been presented in providing the internet's quality of services. The Proportional Differentiated services method is one of the newest ways of providing quality of services. In this essay, a proper...
Cloud computing has gained popularity in recent times. As a cloud must provide services to many users at the same time and different users have different QoS requirements, the scheduling strategy should be developed for multiple workflows with different QoS requirements. In this paper, we introduce a multiple QoS constrained scheduling strategy of multi-workflows (MQMW) to address this problem. The...
