NETWORK VIRTUALIZATION SYSTEM, VIRTUAL RESOURCE MANAGEMENT DEVICE, VIRTUAL RESOURCE MANAGEMENT METHOD AND PROGRAM

Abstract

Upon receiving a virtual network function (VNF) creation request including location information, a VNF manager (VNFM) of a network virtualization system (1000) transmits the VNF creation request to a VNF orchestrator (NFVO) . Using the location information included in the VNF creation request, the NFVO extracts a virtual infrastructure manager (VIM) that satisfies the requirement of the location information with reference to the VIM information, and selects, from among the extracted VIMs, the VIM that satisfies a creation requirement other than the location information with reference to physical device/virtual resource information.

Description

Claims

A network virtualization system that creates a virtual network function (VNF) on a virtual resource, the network virtualization system comprising: an NFV infrastructure (NFVI) that provides a virtual infrastructure by allocating the virtual resource on a plurality of physical devices; a virtualized infrastructure manager (VIM) that controls the physical device and the virtual resource of the NFVI; an NFV orchestrator (NFVO) that selects a VIM that controls an NFVI that deploys a virtual resource that creates the VNF, from among a plurality of sets of the NFVI and the VIM deployed at any same position; and a VNF manager (VNFM) that requests a selected VIM to allocate the virtual resource, whereinthe VNFM includes a VNF information management unit including one or more processors, configured to, upon receiving a VNF creation request including location information in a creation requirement of the VNF, transmit the VNF creation request to the NFVO, andthe NFVO includes: a storage medium configured to store VIM information in which setting information regarding a VIM including location information regarding a deployment position of the VIM itself is stored and physical device/virtual resource information in which state information of the physical device and the virtual resource of each NFVI is stored; anda VIM selection unit including one or more processors, configured to, by using the location information included in the VNF creation request, extract a VIM that satisfies a requirement of the location information with reference to the VIM information, and select, from among the extracted VIMs, a VIM that satisfies a creation requirement other than the location information with reference to the physical device/virtual resource information.

2. A virtual resource management device of a network virtualization system that creates a VNF on a virtual resource, wherein the network virtualization system includes: a NFVI that provides a virtual infrastructure by allocating the virtual resource on a plurality of physical devices; a VIM that controls the physical device and the virtual resource of the NFVI; the virtual resource management device as an NFVO that selects a VIM that controls an NFVI that deploys a virtual resource that creates the VNF, from among a plurality of sets of the NFVI and the VIM deployed at any same position; and a VNFM that requests a selected VIM to allocate the virtual resource, andthe virtual resource management device includes: a storage medium configured to store VIM information in which setting information regarding a VIM including location information regarding a deployment position of the VIM itself is stored and physical device/virtual resource information in which state information of the physical device and the virtual resource of each NFVI is stored; anda VIM selection unit including one or more processors, configured to, upon acquiring a VNF creation request including location information in a creation requirement of the VNF, extract a VIM that satisfies a requirement of the location information with reference to the VIM information, and select, from among the extracted VIMs, a VIM that satisfies a creation requirement other than the location information with reference to the physical device/virtual resource information.

3. The virtual resource management device according to claim 2, wherein the location information is identification information indicating an area where a set of the NFVI and the VIM is deployed, andthe VIM selection unit is configured to extract a VIM located in a same area as an area indicated by location information included in the VNF creation request with reference to the VIM information.

4. The virtual resource management device according to claim 2, wherein the location information is information indicating latitude/longitude where a set of the NFVI and the VIM is deployed, andthe VIM selection unit is configured to extract a VIM located within a predetermined distance from a position indicated by latitude/longitude that is location information included in the VNF creation request with reference to the VIM information.

5. The virtual resource management device according to claim 2, wherein the location information is weight information indicating a distance between a reference VIM and each VIM itself, andthe VIM selection unit is configured to extract a VIM in which a value within a value indicated by weight information that is location information included in the VNF creation request is set with reference to the VIM information.

6. A virtual resource management method by a virtual resource management device of a network virtualization system that creates a VNF on a virtual resource, wherein the network virtualization system includes: a NFVI that provides a virtual infrastructure by allocating the virtual resource on a plurality of physical devices; a VIM that controls the physical device and the virtual resource of the NFVI; the virtual resource management device as an NFVO that selects a VIM that controls an NFVI that deploys a virtual resource that creates the VNF, from among a plurality of sets of the NFVI and the VIM deployed at any same position; and a VNFM that requests a selected VIM to allocate the virtual resource,the virtual resource management device includes a storage medium configured to store VIM information in which setting information regarding a VIM including location information regarding a deployment position of the VIM itself is stored and physical device/virtual resource information in which state information of the physical device and the virtual resource of each NFVI is stored, andthe virtual resource management method executes: acquiring a VNF creation request including location information in a creation requirement of the VNF; andextracting a VIM that satisfies a requirement of the location information with reference to the VIM information and selecting, from among the extracted VIMs, a VIM that satisfies a creation requirement other than the location information with reference to the physical device/virtual resource information.

7. (canceled)

8. The virtual resource management method according to claim 6, wherein the location information is identification information indicating an area where a set of the NFVI and the VIM is deployed, andthe virtual resource management method comprises: extracting a VIM located in a same area as an area indicated by location information included in the VNF creation request with reference to the VIM information.

9. The virtual resource management method according to claim 6, wherein the location information is information indicating latitude/longitude where a set of the NFVI and the VIM is deployed, andthe virtual resource management method comprises: extracting a VIM located within a predetermined distance from a position indicated by latitude/longitude that is location information included in the VNF creation request with reference to the VIM information.

10. The virtual resource management method according to claim 6, wherein the location information is weight information indicating a distance between a reference VIM and each VIM itself, andthe virtual resource management method comprises: extracting a VIM in which a value within a value indicated by weight information that is location information included in the VNF creation request is set with reference to the VIM information.
