摘　　要：针对教育云资源共享中任务调度时优先级不同带来的挑战,提出了一种基于任务优先级的最优调度算法优化教育服务质量。文章首先分析了各种任务的服务质量需求,对任务进行优先级分类,设计了一种基于优先级的队列调度核心算法。然后,分析了所设计调度算法的实施过程和具体步骤。仿真结果验证了优先级队列任务调度算法能够降低系统的处理时延,从而有效提高用户的使用体验。The priority of the task scheduling has brought challenges for education cloud resources.An optimal scheduling algorithm based on task priority to optimize the quality of education service was proposed.Firstly,the quality of service requirements of various tasks was analyzed,and the priority of tasks was classified;a core algorithm of queue scheduling based on priority was designed;then the implementation process and specific steps of the designed scheduling algorithm can analyzed.The simulation results show that the priority queue task scheduling algorithm can reduce the processing delay of the system,so as to effectively improve the user experience.
