本文提出了一个分布式嵌入式应用的通用建模框架。应用程序被分解为服务并映射到一组分布式节点上，而每个节点承载一个或多个服务。每个服务由四个接口描述：实时输入/输出、配置和规划（CP）以及诊断和管理（DM）接口。整个应用程序由集群配置描述来描述，该描述指定了节点内和节点间的服务交互。应用需求、节点的服务属性、服务之间的交互以及应用映射都用XML描述进行了形式化描述。XML格式允许接口的语言中立和可扩展的语义描述，支持用于建模、调度、监控、仿真和验证的上下文感知工具的实现。该模型的核心概念是接口文件系统（IFS），它充当分布式共享内存，并透明地实现从其他节点到服务的接口。原则上，更新IFS数据中的数据的通信系统不受特定实现的约束，只要它满足给定的定时要求即可。所提出的概念应用在一个案例研究中，使用时间触发的现场总线协议TTP/A的一个小型传感器融合应用的实施
This paper presents a framework for generic modeling of distributed embedded applications. An application is decomposed into services and mapped on a set of distributed nodes, whereas each node hosts one or more services. Each service is described by four interfaces: a real-time input/output, a configuration and planning (CP), and a diagnostic and management (DM) interface. The overall application is described by a cluster configuration description that specifies the interaction of services within and across nodes. The application requirements, the service properties of a node, and the interaction of the services as well as the application mapping are described formally with XML descriptions. The XML format allows a language-neutral and extensible semantic description of interfaces supporting the implementation of context-aware tools for modeling, scheduling, monitoring, simulation, and validation. A central concept of the model is the interface file system (IFS) that acts as a distributed shared memory and transparently implements the interfaces to services from other nodes. In principle, the communication system that updates the data in the IFS data is not bound to a specific implementation as long as it fulfills the given timing requirements. The presented concepts are applied in a case study that uses the time-triggered fieldbus protocol TTP/A for the implementation of a small sensor fusion application
