Problems solved by technology

[0004] (1) Unified scheduling of resources;
[0005] (2) Network planning cannot be adjusted quickly and flexibly;
[0007] (4) Difficulties in developing business capabilities;
[0009] The cloud environment and its virtual machines constitute the virtual infrastructure layer NFVI (NFV infrastructure) of VNF, which provides computing resource pools, storage resource pools, and network resource pools. However, the balanced distribution of device resources has not been achieved through virtualization technology. Resource utilization is still relatively low

Embodiment 2

[0061] Please refer to figure 2 , figure 2 Another flowchart of the virtual network function management method provided by this embodiment. The method provided in this embodiment is applicable to the processing of general and special VNF automatic migration in a virtualization scenario, and the processing steps specifically include:

[0062] S201. Enable the cloud environment host cluster VNF load balancing policy.

[0063] S202. Periodically collect load data of the VNF host.

[0064] S203, saving the load data.

[0065] S204. Calculate the average value of historical load data, specifically periodically calculate the average value of historical load data of each host as a key performance indicator, and trigger a migration preparation action when it exceeds a threshold defined in the load balancing policy.

[0066] S205, according to the key performance index information of each host, judge the condition in the load balancing migration policy information, if it does not...

Embodiment 3

[0089] Please refer to Figure 4 , Figure 4 It is a schematic structural diagram of a virtual network function management device provided in this embodiment. The virtual network function management device 4 includes: a decision-making module 41 and a management module 42, wherein:

[0090] The decision-making module 41 is used to obtain key performance indicators of each host in the host cluster, and generate a management policy according to the key performance indicators of each host and a preset load balancing strategy.

[0091] In this embodiment, the decision-making module 41 specifically obtains the key performance indicators of each host in the following manner:

[0092] During the detection period, the load data of each host in the host cluster is periodically obtained, and the key performance indicators of each host are calculated according to the acquired load data of each host. Specifically, the load data includes historical load data and current real-time load d...

Abstract

The embodiment of the invention provides a virtual network function management method and device and a network function virtualization system. The method comprises the steps of obtaining key performance indicators of each host in a host cluster; generating a management policy according to the key performance indicators of each host and a preset load balancing policy; and managing virtual network functions in each host according to the generated management policy. The network function virtualization resource balanced distribution is realized, the processing efficiency of business is prevented from being influenced due to excessive high operation load of partial hosts, a utilization rate of virtual network function resources is improved, and the network function virtualization high availability and stability are improved.

Description

technical field [0001] The present invention relates to the field of network function virtualization, in particular to a virtual network function (Virtual Network Functions, VNF) management method and device thereof, and a network function virtualization (Network Function Virtualization, NFV) system. Background technique [0002] At present, in the traditional telecom market, network elements of different manufacturers and services often run on different hardware devices and operating systems, and some even use some proprietary hardware. In different business fields and different time periods, the utilization rate of equipment is not the same. The configuration of these equipment needs to meet the peak load requirements of a single business, but most of the time these resources cannot be obtained due to the actual business needs. Good use, resulting in waste of equipment resources. [0003] In recent years, the rapid development of cloud computing and virtualization technol...
