Load balancing control method and management node

Abstract

The embodiment of the invention discloses a management node of a load balancing control method. The management node and a plurality of physical hosts are contained in a trunking system, and each physical host comprises a hardware layer, a host machine running on the hardware layer and a virtual machine running on the host machine. The method comprises the steps that the current comprehensive load balancing value of the trunking system is calculated; when the comprehensive load balancing value is larger than a balance degree threshold value, candidate virtual machines to be transferred are selected from the virtual machines running on all the physical hosts in the trunking system to be added to a candidate virtual machine set based on computing resource dimensionality and network resource dimensionality respectively; a target virtual machine to be transferred in the candidate virtual machine set and a target physical host hosted by the target virtual machine are determined based on comprehensive dimensionality; the comprehensive dimensionality comprises the computing resource dimensionality and the network resource dimensionality; a source physical host hosted by the target virtual machine to be transferred is informed to transfer the target virtual machine to be transferred to the target physical host; the source host and the target physical host are both the physical hosts in the trunking system.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a load balancing control method and a management node. Background technique [0002] With the development of virtualization and cloud computing, cloud centers are increasingly used. The cloud center includes at least one cluster system, and each cluster system includes a management node and multiple computing nodes (or called physical hosts), and each physical host can run multiple virtual machines. [0003] In the prior art, it is often judged from the dimension of computing resources (such as CPU utilization, memory utilization) whether the cluster system is load-balanced, and if the judgment is unbalanced, the virtual machine that affects the load balance the most in the dimension of computing resources is selected for migration. . However, this load balancing control method only judges and adjusts based on the dimension of computing resources, and there is still room ...
