【摘要】：云计算下服务器的异构性,由于在于云计算环境下服务器的设计规则较多,无法建立统一的标准的抗毁性评估标准。传统的方法以固定参数描述抗毁性权值,但是,固定权值缺少对不同规则服务器抗毁性描述的灵活性,弊端明显降低了估计的准确性。提出基于服务器容量的云计算下的服务器抗毁性估计方法。根据服务器的容量与权重的关系建立服务器的非线性负载容量模型;在进行服务器抗毁性估计的过程中,考虑到服务器不同容量和节点不同密度对抗毁性的影响,得到准确的抗毁性估计结果;根据服务器抗毁性的估计结果,通过调节服务器容量的方法能够使服务器的抗毁性保持最优。仿真结果表明,改进算法能够提高云计算下服务器抗毁性估计准确性。
[Abstract]:The heterogeneity of servers in cloud computing environment is because there are many rules of server design in cloud computing environment, so it is impossible to establish a unified standard of survivability evaluation standard. The traditional method uses fixed parameters to describe the invulnerability weights, but the fixed weights lack the flexibility to describe the invulnerability of different rule servers, which obviously reduces the accuracy of estimation. This paper proposes a method for estimating the survivability of servers in cloud computing based on server capacity. According to the relationship between the capacity and the weight of the server, the nonlinear load capacity model of the server is established, and in the process of estimating the survivability of the server, the influence of the different capacity of the server and the different density of the node on the survivability of the server is considered. According to the estimation results of server survivability, the server survivability can be optimized by adjusting the server capacity. Simulation results show that the improved algorithm can improve the accuracy of server survivability estimation in cloud computing.
