云数据中心基于负载权重的负载均衡调度算法

摘要

针对现有云数据中心的多维资源利用不均衡问题，提出基于资源负载权重的动态多资源负载均衡调度算法。算法结合服务器各维度资源动态负载情况，构造层次分析法(AHP)判断矩阵来处理多维资源对于负载均衡影响权重大小，在此基础上综合考虑任务资源需求，将任务放置到合适服务器来改善资源利用，实现资源间负载均衡。平台仿真显示新算法可有效提高利用率低的资源的利用效率，在提高整体资源利用率、降低资源间负载不均衡率方面有优势。%To solve the unbalance of multi-dimensional resource utilization in cloud data center, proposes a dynamic load balancing scheduling al-gorithm based on resource workload weight. By using Analytic Hierarchy Process (AHP) based on the dynamic resource utilization of servers to deal with multi-dimensional resources for load-balancing influence weights and consider the task resource requirements, places the right task to the appropriate server in order to improve resource utilization and implements the load-balancing between multi-dimensional resources. Platform emulation shows that the new algorithm can effectively improve the use efficiency especially for the resource which has a low utilization before, and has advantages in improving the overall resource utilization, reduces uneven rates for resource use.
