This paper proposes a novel framework providing a declarative interface to access real-time process scheduling services available in an operating system kernel. The main idea is to let applications declare their temporal requirements or characteristics without knowing exactly which underlying scheduling algorithms are offered by the system. The proposed framework can adequately handle such a set of heterogeneous requirements configuring the platform and partitioning the requests among the available multitude of cores, so to exploit the various scheduling disciplines that are available in the kernel, matching application requirements in the best possible way. The framework is realized with a modular architecture in which different plugins handle independently certain real-time scheduling features. The architecture is designed to make its behavior customization easier and enhance the support for other operating systems by introducing and configuring additional plugins.

本文提出了一个提供声明式接口的新框架访问操作系统内核中可用的实时进程调度服务。主要思想是让应用程序在不确切知道系统提供哪些底层调度算法的情况下声明它们的时间要求或特征。所提出的框架可以充分处理这样一组异构需求，配置平台并在可用的多个内核之间划分请求，以便利用内核中可用的各种调度规则，以最佳方式匹配应用程序需求。该框架采用模块化架构实现，其中不同的插件独立处理某些实时调度功能。
