Abstract

This paper presents a robust scheduling framework for service processes with end-to-end deadlines. Service processes are admitted using capacity-based admission control, which assigns intermediate deadlines for individual services. At run-time, the system can respond to intermediate deadline faults by adjusting the deadlines assigned and reevaluate the system's schedulability. Intermediate deadline adjustment algorithms are proposed to efficiently adjust a subset of the overrunning process. Experimental results show that the proposed intermediate deadline adjustment algorithms can effectively reduce the end-to-end deadline miss ratio by up to 30%, compared to the original system.
具有中间期限超限管理的实时服务进程调度
本文提出了一个具有端到端截止日期的服务过程鲁棒调度框架。使用基于容量的许可控制允许服务流程,该控制为单个服务分配中间截止日期。在运行时,系统可以通过调整分配的截止日期来响应中间截止日期错误,并重新评估系统的可调度性。提出了中间期限调整算法,以有效地调整溢出过程的子集。实验结果表明,与原系统相比,本文提出的中间截止日期调整算法可以有效地将端到端截止日期遗漏率降低30%。
