Abstract
An orchestrating apparatus, comprising: a receiving part that receives virtual resource information attached to a VNF (Virtualized Network Function) from a VNFM (Virtualized Network Function Manager) that generated the VNF; a storage part that stores the virtual resource information in correspondence with the VNF; and a synchronizing part that transmits the virtual resource information corresponding to a designated VNF to a VNFM that has lost correspondence between the VNF and the virtual resource information, and causes the VNFM to restore the virtual resource information assigned to the VNF.
Claims15
An orchestrating apparatus, comprising:
- a memory configured to store instructions, and
- a processor configured to execute the instructions,
- the instructions comprising:
- receiving virtual resource information from a VNFM (Virtualized Network Function Manager) that generated a VNF (Virtualized Network Function), the virtual resource information uniquely identifying virtual resources assigned to the VNF;
- storing the virtual resource information in correspondence with the VNF;
- and
- transmitting the virtual resource information corresponding to a designated VNF to a VNFM that has lost correspondence between the VNF and the virtual resource information, and causing the VNFM to restore the virtual resource information assigned to the VNF,
- wherein the transmitting is performed by transmitting a synchronizing confirmation request designating the VNF to the VNFM, and causing the VNFM to check whether or not the correspondence between the VNF and the virtual resource information has been lost.
A managing method of VNF (Virtualized Network Function) information, comprising:
- receiving virtual resource information assigned to a VNF from a VNFM (Virtualized Network Function Manager) that has generated the VNF, wherein the virtual resource information uniquely identifies virtual resources assigned to the VNF;
- storing the VNF and the virtual resource information in correspondence each other;
- transmitting the virtual resource information corresponding to a designated VNF to a VNFM that has lost correspondence between the VNF and the virtual resource information;
- and
- causing the VNFM to restore the virtual resource information assigned to the VNF,
- wherein the transmitting is performed by transmitting a synchronizing confirmation request designating the VNF to the VNFM, and causing the VNFM to check whether or not the correspondence between the VNF and the virtual resource information has been lost.
A computer-readable recording medium storing a program for causing a computer, to execute:
- a process of receiving a virtual resource information assigned to a VNF (Virtualized Network Function) from a VNFM (Virtual Network Function Manager) that generates the VNF, wherein the virtual resource information uniquely identifies virtual resources assigned to the VNF;
- a process of storing a correspondence between the VNF and the virtual resource information;
- a process of transmitting the virtual resource information corresponding to a designated VNF to a VNFM that has lost correspondence between the VNF and the virtual resource information;
- a process of causing the VNFM to restore the virtual resource information assigned to the VNF, and
- a process of transmitting a synchronizing confirmation request designating the VNF to the VNFM, and a process of causing the VNFM to check whether or not the correspondence between the VNF and the virtual resource information has been lost.
