由于面向服务的体系结构(Service-Oriented Architecture,SOA)对高可靠服务的需求日益增加,服务级别协议越来越频繁地包含安全性、安全性、可用性、可靠性等非功能方面。当一个服务无法再提供所需的服务质量时,服务请求者需要在交换一系列消息后动态切换到具有足够服务参数的新服务。在本文中,我们首先使用服务中可靠的消息传递所需的参数来扩展核心的SOA元模型。然后,我们通过图转换规则为可靠消息传递的重配置建模。最后,结合图变换分析工具和带标签的变迁系统,对提出的规则集进行了形式化验证。
Due to the increasing need of highly dependable services in Service-Oriented Architectures (SOA), service-level agreements include more and more frequently such non-functional aspects as security, safety, availability, reliability, etc. Whenever a service can no longer be provided with the required QoS, the service requester needs to switch dynamically to a new service having adequate service parameters after exchanging a sequence of messages. In the current paper, we first extend the core SOA metamodel with parameters required for reliable messaging in services. Then we model reconfigurations for reliable message delivery by graph transformation rules. Finally, we carry out a formal verification of the proposed rule set by combining analysis tools for graph transformation and labeled transition systems.
