Abstract

An approach towards a framework that enables the static composition of real-time applications from existing ubiquitous services is presented. This framework allows to announce services (specifying their QoS requirements in terms of real-time parameters, such as worst case execution time, WCET), to discover services that perform a certain functionality and to select the set of those discovered services that will be part of the application to be created. Such service set selection is based on the fulfillment of the QoS requirements of the application. The composition is static, i.e., all services required to create an application have to be discovered before launching the whole application. We describe the composition model of the framework and its implementation on top of Jini.
基于服务的实时应用程序的静态组合
提出了一种实现框架的方法,该框架允许从现有的泛在服务中静态组合实时应用程序。这个框架允许宣布服务(根据实时参数指定它们的QoS需求,如最坏情况执行时间,WCET),发现执行特定功能的服务,并选择这些被发现的服务的集合,这些服务将成为要创建的应用程序的一部分。这种服务集的选择是基于应用程序的QoS需求的实现。这种组合是静态的,也就是说,在启动整个应用程序之前,必须发现创建应用程序所需的所有服务。我们描述了框架的组合模型及其在Jini之上的实现。
