Method and system for elastically expanding and contracting smart collaborative network group

The invention provides a method and a system for elastically expanding and contracting a smart collaborative network group. The method is used for realizing on-demand elastic expansion of network groups. The method comprises the following steps: periodically monitoring the resource utilization rate condition of each virtual component of a cluster, calling a threshold decision according to the monitored resource utilization rate condition, allowing to trigger an expansion mechanism when the network capacity is overloaded, and dynamically increasing the resources allocated to the network under the condition that the network service is not interrupted, thereby ensuring the user experience; and meanwhile, when the network resource utilization rate is too low, dynamically reducing the resourcesallocated to the network, and then improving the resource utilization rate of the computing network. 本发明提供了一种智慧协同网络族群弹性伸缩的方法和系统，用于实现网络族群按需弹性伸缩，周期性监控族群的各个虚拟组件的资源利用率情况，通过监测到的资源利用率情况调用阈值决策，允许在网络容量过载时，触发扩容机制，在网络服务不中断的情况下，动态地增加分配
