Abstract: There is provided an apparatus comprising: a unit that receives, from a sender, a registration request of an execution condition of a lifecycle of a virtual function under a virtual environment and registers the execution condition of the lifecycle in a storage unit; a unit that secures in advance one or more resources necessary for execution of the lifecycle in the virtual function; a unit that determines whether or not the execution condition of the lifecycle registered in the storage unit is satisfied; a unit that instructs the execution of the lifecycle when the execution condition of the lifecycle is satisfied; and a unit that notifies the lifecycle execution result to the sender of the registration request of the execution condition of the lifecycle.

Abstract: 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.

Abstract: A virtual network function management apparatus includes: a physical machine candidate query part configured to query, when creating a virtual network function, about a physical machine candidate in which a virtual machine configuring a virtual network function can be deployed, with respect to a virtual infrastructure management apparatus that manages a virtual infrastructure configured by using 2 or more types of physical machine; a physical machine selection part configured to select a physical machine that can satisfy performance required by the virtual network function, from among physical machine candidates received from the virtual infrastructure management apparatus; and a virtual machine creation instruction part configured to instruct the virtual infrastructure management apparatus to specify the selected physical machine and create a virtual machine configuring the virtual network function.
