Abstract

The paper focuses on the problem of providing efficient run time support for different applications running on a real time system. The goal of our research is to develop a scheduling algorithm to allow independent applications to coexist on the same system. In order to meet the requested QoS, we assign each application a minimum bandwidth and guarantee that it never demands more. This algorithm does not require the exact knowledge of the execution times and interarrival times of the application tasks: hence, it is especially suited for soft real time and multimedia applications.

多应用系统的带宽预留算法
本文主要研究如何为运行在实时系统上的不同应用程序提供有效的运行时支持。我们的研究目标是开发一种调度算法,允许独立的应用程序在同一系统上共存。为了满足所要求的QoS,我们为每个应用程序分配了最小带宽,并保证它永远不会需要更多带宽。该算法不需要知道应用程序任务的执行时间和到达间隔时间,因此,它特别适合于软实时和多媒体应用程序。
