Description

Technical Field

[0001] The present invention relates to the field of communication technology, and in particular to a method, device and storage medium for determining energy consumption of a virtual network element. Background Art

[0002] Currently, the energy efficiency calculation method defined by 3GPP for 5G networks uses the ratio of DV to EC, where DV represents data throughput and EC represents energy consumption. Estimating the energy consumption of 5G core network (5GC) network elements is an essential measurement for 5G network energy efficiency analysis. With the widespread use of NFV (Network Function Virtualization) in 5GC, different entities of the same type of network element, and entities of different types of network elements, may include one or more VNFs (Virtualized Network Functions). A VNF can be composed of one or more VNF components (VNFCs). These VNFCs are deployed on the Network Function Virtualization Infrastructure (NFVI), sharing the same physical resource pool.

[0003] Shared physical resources include computing, storage, internal I / O bandwidth, external I / O bandwidth, etc. In order to evaluate the energy efficiency of 5GC, it is necessary to measure the energy consumption of these VNFs. In NVFI, the energy consumption of the entire NFVI can only be measured as a whole. Figure 1 As shown in Figure 2, the relationship between VNFC and NFVI may include: multiple VNFCs constituting a VNF may be deployed on multiple NFVIs; multiple VNFCs can run simultaneously on a single NFVI. Therefore, energy measurements for NFVI cannot be directly mapped to VNFs and NFs. Therefore, a method for calculating VNFC energy consumption is needed. Summary of the Invention

[0037] The present disclosure is described more fully below with reference to the accompanying drawings, which illustrate exemplary embodiments of the present disclosure. The technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present disclosure.

[0038] Figure 2 FIG. 1 is a flow chart of an embodiment of a method for determining energy consumption of a virtual network element according to the present disclosure, as shown in FIG. Figure 2 As shown:

[0039] Step 201: Obtain computing resource occupancy information based on computing resources allocated to the VNFC instance; attributes of the computing resources include CPU (Central Processing Unit) clock frequency and number of CPU cores.

[0040] Step 202: Based on the occupancy information of the computing resources corresponding to the VNFC instance, the total occupancy of the computing resources corresponding to the NFVI is obtained; the VNFC instance is deployed on the NFVI.

[0041] Step 203: Obtain EC information of the VNFC instance to be tested based on the computing resource usage of the VNFC instance to be tested, the total CPU resource consumption information of all VNFC instances of the NFVI, and the total energy consumption information of the NFVI; the EC (Energy Consumption) information is energy consumption information.

[0042] Step 204: Calculate the EC information of the VNF instance to be tested based on the EC information of the VNFC instance.

[0043] Step 205: Obtain the EC information of the NF (Network Function) instance to be tested based on the EC information of each VNF instance to be tested.

[0044] The virtual network element energy consumption determination method disclosed in the present invention calculates the network element (NF) energy consumption based on the computing resource occupancy. For the computing resources (Compute Resource) allocated to the VNFC instance, the computing resource occupancy (vCPU Resource Usage) can be obtained by the following two methods, and its unit is MegaHertz (MHz).

[0045] Figure 3 FIG. 1 is a flow chart of obtaining computing resource occupancy information in an embodiment of a method for determining virtual network element energy consumption according to the present disclosure, as shown in FIG. Figure 3 As shown:

[0046] Step 301: Obtain the processor utilization of the VNFC instance. Existing methods can be used to obtain processor utilization. Processor utilization is a reported value of a measurement quantity that quantifies the ratio of the total time spent by one or more computing resources (determined based on the required measurement range) executing instructions corresponding to a specific context during a measurement period to the measurement period, expressed as a percentage.

[0047] Step 302: Obtain computing resource occupancy information based on processor utilization, CPU clock frequency, and number of CPU cores.

[0048] In one embodiment, the computing resource usage information is obtained based on the average ProcessorUtilization of the VNFC instance within a given time range:

[0049] vCPU Resource Usage=ProcessorUtilization*vCpuClockSpeed*

[0050] vCpuCores(1-1);

[0051] ProcessorUtilization is the processor utilization, vCpuClockSpeed ​​is the CPU clock frequency of the computing resource, and vCpuCores is the number of CPU cores included in the computing resource.

[0052] vCpuClockSpeed ​​is the CPU clock speed of the compute resource, and vCpuCores is the number of CPU cores in the compute resource. Processor Utilization is defined in Section 6.6 of ETSI GS NFV-TST008. The value of Processor Utilization for a VNFC instance is equal to the ratio of the time it takes to execute instructions within a specific scope (e.g., the process containing the VNFC instance) on one or more compute resources to the duration of the measurement interval.

[0053] Figure 4 FIG. 1 is a flow chart of obtaining computing resource occupancy information in another embodiment of the method for determining virtual network element energy consumption according to the present disclosure, as shown in FIG. Figure 4 As shown:

[0054] Step 401: Obtain the average processor usage of the VNFC instance. Existing methods can be used to obtain the average processor usage. The average processor usage is the average value of processor usage; processor usage is a reported value of a measurement quantity that quantifies the total time spent by one or more computing resources (determined based on the required measurement range) executing instructions corresponding to a specific context during a measurement period.

[0055] Step 402: Obtain computing resource occupancy information based on the average processor usage, CPU clock frequency, and number of CPU cores.

[0056] In one embodiment, for fully virtualized computing resources, the occupancy information of the computing resources can also be calculated based on the vCpuUsageMean (recorded in cf. ETSI GSNFV IFA 027 clause 7.1.2) provided by the VIM (Virtualized Infrastructure Manager).

[0057] vCPU Resource Usage=vCpuUsageMean*vCpuClockSpeed*vCpuCores (1-2);

[0058] vCpuUsageMean is the average processor usage time, vCpuClockSpeed ​​is the CPU clock frequency of the vCPU, and vCpuCores is the number of CPU cores of the vCPU.

[0059] In one embodiment, the total computing resource usage is calculated by summing the computing resource usage information corresponding to all VNFC instances. For example, based on the results of formulas (1-1) and (1-2), for a VNFC instance to be tested deployed on a certain NFVI, the total vCPU Resource Usage on this NFVI can be further calculated using the following formula (1-3):

[0060] R VNFC,CPU =∑ ComputeResource {vCPU Resource Usage} (1-3);

[0061] ComputeResource is all computing resources on the NFVI where the VNFC instance to be tested is deployed. For example, for each vCPU on the NFVI, the EC estimate of the VNFC instance to be tested is further calculated:

[0062]

[0063] The numerator is the CPU Resource Consumption of the current VNFC instance to be tested, and the denominator is the sum of the CPU Resource Consumption of all VNFC instances (including the current VNFC instance to be tested) deployed on the NFVI where the current VNFC instance to be tested is deployed, that is, R VNFC,CPU is the CPU resource usage of the VNFC instance to be tested, ∑ VNFC R VNFC,CPU The total CPU resource consumption of all VNFC instances, EC NFVI It is the total energy consumption information of NFVI.

[0064] In one embodiment, the EC information of each VNFC instance constituting the VNF instance to be tested is summed to obtain the EC information of the VNF instance to be tested. The EC information of each VNF instance constituting the NF instance to be tested is summed to obtain the EC information of the NF instance to be tested.

[0065] In formula 1-4, EC NVFI The total energy consumption of the NFVI platform is measured by the instrument on the NFVI, in joules. The EC of the VNF instance under test is calculated by summing the EC of each VNFC instance that constitutes the VNF instance under test:

[0066] EC VNF =∑ VNFCs EC VNFC (1-5);

[0067] Furthermore, the EC of the NF instance to be tested is calculated by accumulating the ECs of the VNF instances that make up the NF instance to be tested:

[0068] EC NF =∑ VNFs EC VNF (1-6).

[0069] The virtual network element energy consumption determination method disclosed in the present invention uses the number of CPU cores and clock rate as necessary parts to measure CPU usage. The number of CPU cores and CPU clock frequency information contained in the computing resources are strongly correlated with the processing time required for the computing resources to process the same number of instructions. Due to the virtualization of resources, different VNFC instances that constitute NF instances / VNF instances can be deployed simultaneously on NFVIs with different computing resource attributes (for example, multiple NFVIs with different hardware resource configurations); on the same NVFI, the mapping relationship between different virtual computing resources and physical computing resources can also be independently configured (for example, exclusive use of a core, or sharing of several cores).

[0070] Existing CPU usage calculation methods, such as Processor Utilization or vCpuUsageMean, only consider the instruction processing time and time ratio, and do not reflect factors related to computing resources and computing power (number of cores and clock frequency). When using existing computing resource measurements for calculations, the CPU usage of different virtual computing resources can only be accumulated if the virtual computing resource attributes occupied by NF / VNF instances are exactly the same.

[0071] The disclosed method for determining virtual network element energy consumption uses duration and the computing power of virtual resources (number of cores and clock frequency) as inputs to calculate computing resource usage. This method does not require that NF instances or VNF instances occupy identical virtual computing resources, making it more universal and accurate, making it more suitable for network resource virtualization scenarios. The energy consumption (in joules) of a VNFC instance can be directly estimated using its CPU resource usage, allowing for direct estimation of the computing power consumption of the core network and virtualized network elements.

[0072] In one embodiment, Figure 5 As shown, the present disclosure provides a virtual network element energy consumption determination device 50, including: a resource occupancy determination module 51, a total resource determination module 52, a first EC information acquisition module 53, a second EC information acquisition module 54 and a third EC information acquisition module 55.

[0073] The resource occupancy determination module 51 obtains computing resource occupancy information based on the computing resources allocated to the VNFC instance. The computing resource attributes include CPU clock frequency and number of CPU cores. The total resource amount determination module 52 obtains the total amount of computing resource occupancy corresponding to the NFVI based on the computing resource occupancy information corresponding to the VNFC instance. The VNFC instance is deployed on the NFVI.

[0074] The first EC information acquisition module 53 obtains the EC information of the VNFC instance to be tested based on the CPU resource usage of the VNFC instance to be tested, the total CPU resource consumption of all VNFC instances, and the total energy consumption of the NFVI. The second EC information acquisition module 54 calculates the EC information of the VNF instance to be tested based on the EC information of the VNFC instance. The third EC information acquisition module 55 obtains the EC information of the NF instance to be tested based on the EC information of each VNF instance to be tested.

[0075] In one embodiment, the resource occupancy determination module 51 obtains the processor utilization of the VNFC instance and obtains computing resource occupancy information based on the processor utilization, CPU clock frequency, and number of CPU cores. Alternatively, the resource occupancy determination module 51 obtains the average processor usage of the VNFC instance and obtains computing resource occupancy information based on the average processor usage, CPU clock frequency, and number of CPU cores.

[0076] The total resource amount determination module 52 calculates the sum of the computing resource occupancy information corresponding to all VNFC instances to obtain the total computing resource occupancy. The second EC information acquisition module 54 calculates the sum of the EC information of each VNFC instance that constitutes the VNF instance to be tested to obtain the EC information of the VNF instance to be tested. The third EC information acquisition module 55 calculates the sum of the EC information of each VNF instance that constitutes the NF instance to be tested to obtain the EC information of the NF instance to be tested.
