基于模拟谐振子算法的服务调度技术

Service scheduling technique based on simulated harmonic oscillator algorithm

为解决服务频繁调度的异常问题,采用谐振子理论方法,在分析云滴概念基础上,提出云滴WEB服务节点距离的定义,并以此为基础,构建一种服务调度距离模型,抽象出一种应用服务调用的实现框架.采用基于排列的方法和串行服务进度生成机制,结合多服务的任务列表,可以保证所得调度方案满足服务优先关系约束,协同完成云计算应用服务的调度工作.仿真试验表明,耗费时间较少.

According to the service frequent scheduling anoma- lies, the definition of cloud droplet WEB service node distance is put forward, adopting simulated harmonic oscillator method based on analyzing the cloud droplets concept. From the per- spective of cloud computing, a service scheduling distance model is hereby constructed on basis of the aforesaid, and an imple- mentation framework using service scheduling is abstracted. Combining with method based on order and serial schedule gen- eration schemes and multi-service task list, the obtained schedu- ling scheme can meet the service schedule constraints of preced- ence relations for the coordination completion of the cloud com- puting application service combination task. The experiment and simulation indicate that the time consumed is less.
