摘要: 针对密码服务系统虚拟化结构复杂导致性能建模难度大的问题,提出了一种基于交互随机子模型(Interactive Stochastic Sub-Models, ISSMs)的性能建模方法,将任务执行过程划分为主机预处理和运算单元执行两个阶段,并基于排队论分别建立了两个子模型在此基础上对密码服务系统虚拟化性能模型的有效性进行了验证。结果表明,所建模型能够定量分析任务的到达速率、主机配置与密码卡配置对系统性能的影响,该模型同时也有助于指导云计算环境下密码服务系统虚拟化部署方案的设计。

Abstract: The complicated architecture of cryptographic service system virtualization raised the difficulty of performance modeling. A performance modeling approach based on ISSMs was proposed. The approach divided the execution process into two stages, host preprocessing and arithmetic-module calculating, and built two sub-models based on queuing theory. On this basis, the effectiveness of this approach was verified. The results show that this method can analyze the impacts on system performance caused by task arrival rates, host and cryptographic card configurations quantitatively, and also be helpful for providing reasonable solutions to deploy virtualized cryptographic service system on cloud computing platforms.
