摘要: 分布式实时系统具有动态性、分布性等特征,为了使其具有较好的执行效率,需要一种有效的调度算法来进行任务的调度。本文在采用多队列调度策略的基础上,对一些有安全级别限制的系统,设计一种支持队列公平和安全策略的多队列调度算法。最后,给出该算法在网格模拟器上的测试结果,并与一些算法进行比较。结果表明,本算法在大任务量情况下,满足安全性要求,较好地实现队列公平。

Abstract: Distributed real-time system has characteristics such as dynamic, distributed and so on. In order to make it a better execution efficiency, an efficient scheduling algorithm to carry out the task scheduling is needed. This paper designs an algorithm on multi-queue scheduling supporting fairness of queues and security policy for some distributed real-time systems with security restrictions.Finally, the test results of this algorithm in the grid simulator are given.And it also compared with some other scheduling algorithm. The results show that this algorithm in the case of large tasks meets the security requirements, and realizes the fairness of queues preferably.

Key words: distributed real-time system, fairness of queues, security policy, mapping mechanism
