[0020] The present disclosure will now be described with reference to the attached drawing figures, wherein like reference numerals are used to refer to like elements throughout, and wherein the illustrated structures and devices are not necessarily drawn to scale. As utilized herein, terms "component," "system," "interface," and the like are intended to refer to a computer-related entity, hardware, software (e.g., in execution), and/or firmware. For example, a component can be a processor (e.g., a microprocessor, a controller, or other processing device), a process running on a processor, a controller, an object, an executable, a program, a storage device, a computer, a tablet PC and/or a user equipment (e.g., mobile phone, etc.) with a processing device. By way of illustration, an application running on a server and the server can also be a component. One or more components can reside within a process, and a component can be localized on one computer and/or distributed between two or more computers. A set of elements or a set of other components can be described herein, in which the term "set" can be interpreted as "one or more."

[0021] Further, these components can execute from various computer readable storage media having various data structures stored thereon such as with a module, for example. The components can communicate via local and/or remote processes such as in accordance with a signal having one or more data packets (e.g., data from one component interacting with another component in a local system, distributed system, and/or across a network, such as, the Internet, a local area network, a wide area network, or similar network with other systems via the signal).

[0022] As another example, a component can be an apparatus with specific functionality provided by mechanical parts operated by electric or electronic circuitry, in which the electric or electronic circuitry can be operated by a software application or a firmware application executed by one or more processors. The one or more processors can be internal or external to the apparatus and can execute at least a part of the software or firmware application. As yet another example, a component can be an apparatus that provides specific functionality through electronic components without mechanical parts; the electronic components can include one or more processors therein to execute software and/or firmware that confer(s), at least in part, the functionality of the electronic components. [0023] Use of the word exemplary is intended to present concepts in a concrete fashion. As used in this application, the term "or" is intended to mean an inclusive "or" rather than an exclusive "or". That is, unless specified otherwise, or clear from context, "X employs A or B" is intended to mean any of the natural inclusive permutations. That is, if X employs A; X employs B; or X employs both A and B, then "X employs A or B" is satisfied under any of the foregoing instances. In addition, the articles "a" and "an" as used in this application and the appended claims should generally be construed to mean "one or more" unless specified otherwise or clear from context to be directed to a singular form. Furthermore, to the extent that the terms "including", "includes", "having", "has", "with", or variants thereof are used in either the detailed description and the claims, such terms are intended to be inclusive in a manner similar to the term

"comprising."

[0024] As used herein, the term "circuitry" may refer to, be part of, or include an Application Specific Integrated Circuit (ASIC), an electronic circuit, a processor (shared, dedicated, or group), and/or memory (shared, dedicated, or group) that execute one or more software or firmware programs, a combinational logic circuit, and/or other suitable hardware components that provide the described functionality. In some embodiments, the circuitry may be implemented in, or functions associated with the circuitry may be implemented by, one or more software or firmware modules. In some embodiments, circuitry may include logic, at least partially operable in hardware.

[0025] Embodiments described herein may be implemented into a system using any suitably configured hardware and/or software. FIG. 3a illustrates components of a network in accordance with some embodiments. In various aspects, part(s) or all of one or more of the components illustrated in connection with FIG. 3a and network functions associated therewith, can be implemented as virtual network functions (VNFs) or VNF instances in connection with various aspects described herein. An Evolved Packet Core (EPC) network 380 is shown to include a Home Subscriber Server (HSS) 383, a Mobility Management Entity (MME) 384, a Serving GateWay (SGW) 385, a Packet Data

Network (PDN) GateWay (PGW) 386, a Policy and Charging Rules Function (PCRF) 387.

[0026] The HSS 383 comprises one or more databases for network users, including subscription-related information to support the network entities' handling of

communication sessions. For example, the HSS 383 may provide support for routing/roaming, authentication, authorization, naming/addressing resolution, location dependencies, etc. The EPC network 380 may comprise one or several HSSs 383, depending on the number of mobile subscribers, on the capacity of the equipment, on the organization of the network, etc.

[0027] The MME 384 is similar in function to the control plane of legacy Serving General packet radio service (GPRS) Support Nodes (SGSN). The MMEs 384 manage mobility aspects in access such as gateway selection and tracking area list

management. The EPC network 380 may comprise one or several MMEs 384

[0028] The SGW 385 terminates the interface toward an Evolved UMTS (Universal Mobile Telecommunications System) Terrestrial Radio Access Network (E-UTRAN), and routes data packets between the E-UTRAN and the EPC network 380. In addition, the SGW 385 may be a local mobility anchor point for inter-eNodeB handovers and also may provide an anchor for inter-3GPP mobility. Other responsibilities may include lawful intercept, charging, and some policy enforcement.

[0029] The PGW 386 terminates an SGi interface toward the PDN. The PGW 386 routes data packets between the EPC network 380 and external networks, and may be a node for policy enforcement and charging data collection. The PCRF 387 is the policy and charging control element of the EPC network 380. In a non-roaming scenario, there may be a single PCRF in the Home Public Land Mobile Network (HPLMN) associated with a User Equipment's (UE) Internet Protocol Connectivity Access Network (IP-CAN) session. In a roaming scenario with local breakout of traffic, there may be two PCRFs associated with a UE's IP-CAN session: a Home PCRF (H-PCRF) within a HPLMN and a Visited PCRF (V-PCRF) within a Visited Public Land Mobile Network (VPLMN). The PCRF 387 may be communicatively coupled to an application server (alternatively referred to as application function (AF)). Generally, the application server is an element offering applications that use Internet Protocol (IP) bearer resources with the core network (e.g., UMTS Packet Services (PS) domain, Long Term Evolution (LTE) PS data services, etc.). The application server may signal the PCRF 387 to indicate a new service flow and selecting the appropriate Quality of Service (QoS) and charging parameters. The PCRF 387 may provision this rule into a Policy and Charging

Enforcement Function (PCEF) (not shown) with the appropriate traffic flow template (TFT) and QoS class of identifier (QCI), which commences the QoS and charging as specified by the application server. [0030] The components of the EPC 380 may be implemented in one physical node or separate physical nodes. In some embodiments, Network Functions Virtualization (NFV) is utilized to virtualize any or all of the above described network node functions via executable instructions stored in one or more computer readable storage mediums (described in further detail below). A logical instantiation of the EPC network 380 may be referred to as a network slice 381 . A logical instantiation of a portion of the EPC network 380 may be referred to as a network sub-slice 382 (e.g., the network sub-slice 382 is shown to include the PGW 386 and the PCRF 387).

[0031] Fig. 3b is a block diagram illustrating components, according to some example embodiments, able to read instructions from a machine-readable or computer- readable medium (e.g., a machine-readable storage medium) and perform any one or more of the methodologies discussed herein. Specifically, FIG. 3b shows a

diagrammatic representation of hardware resources 300 including one or more processors (or processor cores) 310, one or more memory/storage devices 320, and one or more communication resources 330, each of which are communicatively coupled via a bus 340. For embodiments where node virtualization (e.g., NFV) is utilized, a hypervisor 302 may be executed to provide an execution environment for one or more network slices/sub-slices to utilize the hardware resources 300.

[0032] The processors 310 (e.g., a central processing unit (CPU), a reduced instruction set computing (RISC) processor, a complex instruction set computing (CISC) processor, a graphics processing unit (GPU), a digital signal processor (DSP) such as a baseband processor, an application specific integrated circuit (ASIC), a radio-frequency integrated circuit (RFIC), another processor, or any suitable combination thereof) may include, for example, a processor 312 and a processor 314. The memory/storage devices 320 may include main memory, disk storage, or any suitable combination thereof.

[0033] The communication resources 330 may include interconnection and/or network interface components or other suitable devices to communicate with one or more peripheral devices 304 and/or one or more databases 306 via a network 308. For example, the communication resources 330 may include wired communication components (e.g., for coupling via a Universal Serial Bus (USB)), cellular

communication components, Near Field Communication (NFC) components, Bluetooth® components (e.g., Bluetooth® Low Energy), Wi-Fi® components, and other communication components.

[0034] Instructions 350 may comprise software, a program, an application, an applet, an app, or other executable code for causing at least any of the processors 310 to perform any one or more of the methodologies discussed herein. The instructions 350 may reside, completely or partially, within at least one of the processors 310 (e.g., within the processor's cache memory), the memory/storage devices 320, or any suitable combination thereof. Furthermore, any portion of the instructions 350 may be transferred to the hardware resources 300 from any combination of the peripheral devices 304 and/or the databases 306. Accordingly, the memory of processors 31 0, the memory/storage devices 320, the peripheral devices 304, and the databases 306 are examples of computer-readable and machine-readable media.

[0035] Various embodiments described herein can facilitate to perform performance measurement job operations associated with performance measurement (PM) jobs configured to collect virtualized resources (VR) performance measurement (PM) data associated with Virtualized Network Functions (VNFs) deployed in a network function virtualization infrastructure (NFVI) of an NFV network.

[0036] The performance of an application software is tightly coupled to the hardware resource on which the application software is running. For example, this can be when a web application is running so slowly that it may take minutes to display the web page that contains multimedia content, such as pictures, video, audio, text, etc. When this happens, a common response is to launch a task manager to see how the computer hardware is performing. The task manager can display the statistics of CPU, memory, disc, and network (i.e. WiFi, or Ethernet) usages.

[0037] The following are a few example scenarios that can be found from the task manager: (1 ) CPU 100%, memory 100%, network 70%, which may indicate that the computer is using all its resources to process the multimedia content; (2) CPU 10%, memory 40%, network 10%, which may indicate that the application server is too busy to provide the content on time; or (3) CPU 5%, memory 85%, network 30%, which may indicate that the application is pending on the availability of certain resources (e.g., memory) that have been exhausted due to unknown reasons.

[0038] These different scenarios can result from different circumstances, each of which can be analogous to scenarios that can occur in connection with Network Function Virtualization (NFV). To insure that the VNFs deployed on the NFV

infrastructure (NFVI) is able to deliver a consistent and acceptable service quality to end users, as well as to isolate and correct failure conditions at the most timely manner, the virtualized resource performance measurements are required. These performance measurements need to reflect the way VNFs are impacted by the NFVI services, and the inherent nature of the services being offered by the NFVI, for example, CPU, Virtual Machines, memory, and Virtual Networks.

[0039] In various embodiments, techniques described herein can be employed to perform performance measurement job operations associated with PM jobs configured to collect virtualized resources (VR) performance measurement (PM) data (e.g., CPU usage, memory usage etc.) associated with Virtualized Network Functions (VNFs) deployed in a network function virtualization infrastructure (NFVI). In particular, in this disclosure, an apparatus and a method to perform PM job operations that include PM job creation, PM job deletion, PM job suspension, PM job resume, PM job listing and PM availability notification are proposed.

[0040] Referring to FIG. 1 , illustrated is a diagram of a network function virtualization (NFV) system/network 100 that facilitates to perform performance measurement (PM) job operations in connection with various aspects described herein. The system illustrated in FIG. 1 comprises a Network Manager (NM) 102, Network Function

Virtualization (NFV) Orchestrator (NFVO) 104, Element Manager (EM) 106, a set of Virtualized Network Functions (VNFs) or VNF instances, for example VNF1 108a and VNF2 108b virtualized by Virtualization Resources (VRs) of a NFV Infrastructure (NFVI) 108, a VNF Manager (VNFM) 1 10, and a Virtualized Infrastructure Manager (VIM) 1 12. The solid lines between these entities indicate the various reference points that facilitate data exchange between these entities, while the dashed and dotted lines indicate the flow of VR PM data.

[0041] For example, the reference point Ve-Vnfm-Em 109 between the EM 106 and the VNFM 1 10 facilitates a signal/data flow between the EM 1 06 and the VNFM 1 10, the reference point Itf-N 103 between the NM 102 and the EM 106 facilitates a signal/data flow between the NM 1 02 and the EM 1 06, the reference point Vi-Vnfm 1 1 1 between the VNFM 1 10 and the VIM 1 12 facilitates a signal/data flow between the VNFM 1 10 and the VIM 1 12, and the reference point Nf-Vi 107 between the VIM 1 12 and the NFVI 108 facilitates a signal/data flow between the VIM 1 12 and the NFVI 108. In some embodiments, the NFV network 100 enables to perform various PM job operations that include PM job creation, PM job deletion, PM job suspension, PM job resume, PM job listing and PM availability notification. In some embodiments. In some embodiments, the various reference points, for example, Ve-Vnfm-Em 109, Itf-N 103, Vi-Vnfm 1 1 1 , Nf- Vi 107 etc. support a capability to perform a signal/data flow associated with the various PM job operations.

[0042] For example, in one embodiment, in order to collect VR PM data associated with the VNFs (e.g., 108a, 108b) deployed on the NFVI 108, a PM job can be created. In such embodiments, the NM can create a PM job at the EM by sending request to the EM that contains the measurement types, and the periods for which the collection of the VR PM data is to be performed. Similarly, the EM can create a VR PM job at the VNFM by sending a request that contains the same information as received from the NM. Further, the VNFM can create a VR PM job at the VIM by sending a request that contains the same information as received from the EM. The VIM can request the NFVI to collect the VR PM data based on a schedule and time period defined in the VR PM job. In some embodiments, the VR PM data collected by the NFVI 108 are stored in data repositories, for example, repository 1 1 2a, repository 1 1 0a or repository 106a. In other embodiments, other PM job operations, for example, PM job deletion, PM job suspension etc. can also be performed. The signal flow associated with the different PM job operations are described in detail in subsequent embodiments below.

[0043] Fig. 2 illustrates an example flow diagram that depicts the signal flow between the various entities in a network function virtualization (NFV) network 200 that facilitates to perform PM job operations according to various aspects described herein. The NFV network 200 comprises a network manager (NM) 202, an element manager (EM) 204, a virtualized network function manager (VNFM) 206 and a virtualized infrastructure manager (VIM) 208. In some embodiments, the NFV network 200 further comprises an NFV infrastructure (NFVI) with virtualized network functions (VNFs) deployed using the virtualized resources of the NFVI (not shown). In some embodiments, the NFV network 200 is similar to the NFV network 100 described above with respect to Fig. 1 . In some embodiments, in order to perform a PM job operation associated with PM jobs, the NM 202 within the NFV network 200 is configured to initiate a signal flow associated therewith. The PM job operations include PM job creation, PM job deletion, PM job suspension, PM job resume and PM job listing. [0044] For example, in some embodiments, the NM 202 initiates a PM job operation by outputting/sending an NM request 210 comprising a request associated with one or more performance measurement (PM) jobs to the EM 204. In some embodiments, the NM request 210 comprises a request to create a PM job, a request to stop/delete a PM job, a request to suspend a PM job, a request to resume a PM job or a request to list PM jobs. Upon receiving the NM request 210, the EM 204 is configured to output an EM request 212 comprising a request associated with the one or more PM jobs to a virtualized network function manager (VNFM) 206. In some embodiments, the EM request 212 is generated at the EM 204, based on the received NM request 21 0. Upon receiving the EM request 21 2, the VNFM 206 is configured to output a VNFM request 214 comprising a request associated with the one or more PM jobs to a virtualized infrastructure manager (VIM) 208. In some embodiments, the VNFM request 214 is generated at the VNFM 206, based on the received EM request 212.

[0045] Upon processing the VNFM request 214, the VIM 208 is configured to output a VIM response 216 to the VNFM 206, in response to the VNFM request 214. In some embodiments, the VIM response 21 6 comprises information on identifiers that identifies the one or more PM jobs. Upon receiving the VIM response 216, the VNFM 206 is configured to output a VNFM response 218 to the EM 204, based on the received VIM response 218. In some embodiments, the VNFM response 218 comprises information on identifiers that identify the one or more PM jobs. Upon receiving the VNFM response 21 8, the EM 204 is configured to output an EM response 220 to the NM 202. In some embodiments, the EM response 220 is generated at the EM 204, based on the received VNFM response 218 and the EM response 220 comprises a parameter indicating a result of the respective PM jobs.

[0046] In one embodiment, where the PM job operation comprises a PM job creation, the NM request 210 comprises a request to create a PM job. In such embodiments, the NM request 210 includes job information parameters, for example, an object instance identifier, for example, a VNF instance identifier, iOCInstanceList and/or a VNF class identifier, iOCName, that identifies the VNF instance for which the PM job is to be created. In some embodiments, the NM request 210 further include parameters that identify the measurement types to be collected (e.g., measurementCategoryList), reporting period, start time of PM job operation, stop time of PM job operation, granularity period, schedule of the PM job operation, priority of the PM job etc.

Similarly, for PM job creation, the EM request 21 2 comprises an object instance identifier (e.g., sourceSeiector) that identify the VNF instances for which the PM job is to be created and parameters that identify the measurement types to be collected (e.g., performanceMetric and performanceMetricGroup). In addition, the EM request 212 comprises parameters including, a collection period for the respective VNFM (e.g., VNFM 206), a reporting period for the VNFM, reportingBoundary that identifies a stop time for reporting etc. Further, the VNFM request 214 comprises an object instance identifier (e.g., resourceSeiector) that identify the VNF instances for which the PM job is to be created, and parameters that identify the measurement types to be collected (e.g.,

performanceMetric and performanceMetricGroup). In addition, the VNFM request 214 comprises parameters including a collection period for the respective VIM (e.g., VIM 208), a reporting period for the VIM, reportingBoundary that identifies a stop time for reporting etc.

[0047] Furthermore, upon successful creation of a PM job, the VIM response 216 comprises a PM job identifier, for example, pmJobId, that identifies the PM job created. Similarly, the VNFM response 218 comprises a PM job identifier, for example, pmJobId, that identifies the PM job created. In addition, the EM response 220 comprises a parameter, status, indicating a result of the PM job creation and a PM job identifier, for example, jobld, that identifies the PM job created, when the PM job is successfully created. In some embodiments, the PM job identifier, jobld and the PM job identifier, pmJobId are the same, or there is one on one mapping between the PM job identifiers, jobld and pmJobId. In some embodiments, the EM response 220 further comprises a parameter, for example, unsupportedList, that identifies one or more reasons for an unsuccessful or a partially successful creation of the PM job, when the PM job is not successfully created.

[0048] The Table 1 below indicate an example use case of a PM job creation, according to one embodiment of the disclosure. Table 1 : Use Case of PM job creation

[0049] Similarly, Table 2 below indicate an example use case of a PM job creation, according to another embodiment of the disclosure. Table 2: Use Case of PM job creation

[0050] In one embodiment, where the PM job operation comprises a PM job deletion, the NM request 210 comprises a request to stop/delete a PM job. In such embodiments, it is assumed that the PM job to be deleted already exists or is created. In such embodiments, the NM request 210 includes a PM job identifier, for example, Jobld, that identifies the PM job that is to be deleted/stopped.
