METHOD OF CONTROLLING VIRTUAL NETWORK FUNCTION, VIRTUAL NETWORK FUNCTION MANAGEMENT DEVICE, AND VIRTUAL NETWORK PROVIDING SYSTEM

摘要

The invention optimizes a VM (virtual machine) that configures a virtual network function. A virtual network function management apparatus obtains information related to performance of a physical machine allocated to the virtual network function. The virtual network function management apparatus transmits information related to the performance of the physical machine allocated to the virtual network function to a virtual machine that configures the virtual network function. The virtual network function management apparatus causes the virtual machine that configures the virtual network function to change a congestion determination threshold that is set to the virtual machine based on the performance of the physical machine.
