摘要
针对云计算下数据冗余较为严重,框架节点负载不均衡及节点负载调度响应速度慢的问题,设计了一种可靠性高的高弹性云构架框架.通过对云框架下网络中拥塞过程建模,确定云数据真实负载需求,减少冗余数据对路径的占用,并使用弹性约束参数计算云框架下的弹性约束信息.利用蚁群算法获得最大弹性约束下云空间内的均衡最优节点,计算需求弹性,降低对云框架负载影响.结果表明:常规云计算网络下,设计的云构架节点负载调度响应速度快,且节点分布均匀,负载率高,表明设计的云构架计算效率较高.
In order to solve the problems of serious data redundancy,unbalanced load of framework nodes and slow response speed of node load scheduling under cloud computing,a reliable cloud framework with high elasticity was designed.By modeling the congestion process in the network under cloud framework,the real load demand of cloud data was determined,and the path occupation by redundant data was reduced.Elastic constraint parameters were used to compute elastic constraint information under cloud framework.An ant colony algorithm was used to obtain the equilibrium optimal nodes in the cloud space under the maximum elastic constraint,and the demanded elasticity was calculated to reduce its effect on the load of cloud framework.The results show that the response speed of node load scheduling of designed cloud framework is fast,the node distribution is uniform and the load rate is high,indicating that the designed cloud framework has high computing efficiency.
