Apparatus of performance measurement data subscription for nfv performance management

A computer-readable medium storing executable instructions that, in response to execution, cause one or more processors of a network manager (NM), to perform operations comprising:

• outputting a network manager (NM) subscription request generated at the NM, to an element manager (EM) in a network function virtualization (NFV) network having one or more virtual network function (VNF) instances associated therewith, wherein the NM subscription request comprises a request to subscribe to a notification associated with a virtualization resources (VR) performance measurement (PM) data of a VNF instance of the one or more VNF instances, wherein the VNF instance implements a network function associated with an evolved packet core (EPC) network;
• and
• processing an EM subscription response received from the EM, in response to the NM subscription request, wherein the EM subscription response comprises information on a result of the subscription.

A computer-readable medium storing executable instructions that, in response to execution, cause one or more processors of an element manager (EM), to perform operations comprising:

• outputting an EM subscription request generated at the EM, to a virtualized network function manager (VNFM) in a network function virtualization (NFV) network having one or more virtual network function (VNF) instances associated therewith, wherein the EM subscription request comprises a request to subscribe to a notification associated with a virtualization resources (VR) performance measurement (PM) data of a VNF instance of the one or more VNF instances, wherein the VNF instance implements a network function associated with an evolved packet core (EPC) network;
• and
• processing a VNFM subscription response received from the VNFM, in response to the EM subscription request, wherein the VNFM subscription response comprises information on the subscription.

A computer-readable medium storing executable instructions that, in response to execution, cause one or more processors of a virtualized infrastructure manager (VIM), to perform operations comprising:

• processing a virtualized network function manager (VNFM) subscription request received from a VNFM in a network function virtualization (NFV) network having one or more virtual network function (VNF) instances associated therewith, wherein the VNFM subscription request comprises a request to subscribe to a notification associated with a virtualization resources (VR) performance measurement (PM) data of a VNF instance of the one or more VNF instances wherein the VNF instance implements a network function associated with an evolved packet core (EPC) network;
• and
• outputting a VIM subscription response to the VNFM, in response to the VNFM subscription request, wherein the VIM subscription response comprises information on the subscription.
