“…A number of fault tolerance strategies for Web services have been proposed in the recent literature (Chan et al 2007;Foster et al 2003;Salatge and Fabre 2007;Zheng and Lyu 2009). The major approaches can be divided into two types: 1) sequential strategies, where a primary service is invoked to process the request and some backup services are invoked only when the primary service fails.…”

Service-Oriented Architecture (SOA) is widely adopted for building mission-critical systems, ranging from on-line stores to complex airline management systems. How to build reliable SOA systems becomes a big challenge due to the compositional nature of Web services. This paper proposes an adaptive QoS-aware fault tolerance strategy for Web services. Based on a user-collaborated QoS-aware middleware, SOA systems can dynamically adjust their optimal fault tolerance configurations to achieve optimal service reliability as well as good overall performance. Both the subjective user requirements and the objective system performance of the Web services are considered in our adaptive fault tolerance strategy. Experiments are conducted to illustrate the advantages of the proposed adaptive fault tolerance strategy. Performance and effectiveness comparisons of the proposed adaptive fault tolerance strategy and various traditional fault tolerance strategies are also provided.

“…In literature (Zheng and Lyu, 2009;Zheng and Lyu, 2008;Tan, Chen, Andre, Sun, Liu and Dong, 2014), the replication strategy, also known as the redundant international trade, is applied to ensure the reliable execution of the combined international trade. Trade mediation is an effective way to achieve highly reliable international trade.…”

In view of the low efficiency of the traditional international trade vector model based on gravity field theory in the integrated Internet environment, this paper has proposed a fast and reliable international trade vector model based on gravity field theory. The method first applies the gravity analysis to evaluate the international trade friction; and then adopt the multi-attribute decision-making theory to conduct trade mediation on the long-term conflicts in the international trade; finally, through the improved particle swarm optimization algorithm, to make compensation for the long-term conflicts in the international trade. The experimental results based the real data set show that, the proposed method is superior to other methods in the aspect of friction elimination rate, friction treatment time and the combined optimal degree.

“…However, it can provide some of the required building blocks as outlined above [7]. A key challenge in SOA, in particular for service composition infrastructures, is to develop mechanisms to achieve socalled self-adaptive and dependable service compositions [8], [9]. A self-adaptive and dependable composite service is capable of reacting to changes in the environment [10] and has the ability to deliver services that can justifiably be trusted [11].…”

Abstract-We propose a domain-specific service selection mechanism and system implementation to address the issue of runtime adaptation of composite services that implement mission-critical business processes. To this end, we leverage quality of service (QoS) as a means to specify rigid dependability requirements. QoS does not include only common attributes such as availability or response time but also attributes specific to certain business domains and processes. Therefore, we combine both domain-agnostic and domainspecific QoS attributes in an adaptive QoS model. For specifying the service selection strategy, we propose a domain-specific language called VieDASSL to specify so-called selectors. This language can be used to specify selector implementations based on the available QoS attributes. Both the QoS model implementation and the selectors can be adapted at runtime to deal with changing business and QoS requirements. Our approach is implemented on top of an existing WS-BPEL engine. We demonstrate its feasibility by implementing a case study from the telecommunication domain.
