摘要
针对虚拟资源在共享模式下面临的安全性问题,本研究利用资源利用效率建立了一套排队理论模型,该模型考虑到共享模式中经典的三段式结构,搭建了用户、共享云系统和共享虚拟资源三者之间的系统结构和响应流程。通过建立共享模式下服务性能指标将虚拟资源共享系统分为了四个组成部分,结合用户请求到达率和资源输出在请求缓冲池中建立了排队等待系统模型。该模型实现了不同参数化输入到不同服务性能输出的转化,提高了复杂的虚拟资源共享利用率。
Aiming at the security problem faced by virtual resources in sharing mode,this study builds up a queuing theory model using resource utilization efficiency. This model takes into account the classic three-stage structure in shared mode,builds users,shares the cloud system and shares Virtual resources between the three system structure and response process. The virtual resource sharing system is divided into four parts by establishing the service performance index in the shared mode. The queuing system model is established in the request buffer pool according to the user request arrival rate and the resource output. The model realizes the conversion of different parameter input to different service performance output,and improves the utilization ratio of complex virtual resource sharing.
