MANAGEMENT SYSTEM, VIRTUAL COMMUNICATION-FUNCTION MANAGEMENT NODE, AND MANAGEMENT METHOD

摘要

Leakage of detailed information for implementing a virtual server to execute a communication process on virtualization resources is prevented. There is provided a management system (10) included in a mobile communication system (1) configured to include an NFVI (60) which is virtualization resources including a physical server generated by a VNF (70) to execute a communication process, and the system includes a VNFM (30) for managing the VNF (70), a VIM (40) for managing the virtualization resources of the NFVI (60), an orchestrator (20) for managing all the virtualization resources of the NFVI (60), wherein the VNFM (30) includes a retention section (31) configured to retain detailed information for implementing the VNF (70) and a virtual server generation request section (32) configured to request the VIM (40) to generate the VNF (70) using the detailed information.

1. A management system which is included in a communication system configured to include virtualization resources including a physical server in which a virtual server for executing a communication process is generated and which includes a virtual communication-function management node for managing a function of executing the communication process provided in the virtual server, a virtualization resource management node for managing the virtualization resources, and an overall management node for managing all the virtualization resources,
wherein the virtualization resource management node includes circuitry configured to: monitor a use state of the virtualization resources; perform reservation by receiving a request of the reservation of necessary resources for generation of the virtual server among the virtualization resources; and generate the virtual server by receiving a request for generating the virtual server on the necessary resources for the generation of the virtual server reserved, wherein the overall management node includes circuitry configured to: receive a request related to a function of the communication process accompanied by the generation of the virtual server in the physical server, wherein the management system includes circuitry configured to: calculate the necessary resources for the generation of the virtual server on the basis of the request received and the use state of the virtualization resources monitored and request the virtualization resource management node to perform the reservation, and wherein the virtual communication-function management node includes circuitry configured to: retain detailed information for implementing the virtual server on the virtualization resources; and generate the request for generating the virtual server on the necessary resources reserved using the detailed information retained for the virtualization resource management node.
