Description

VNF registration method, device, medium and equipment

Technical Field

The present invention relates to the field of Network Function Virtualization (NFV), and in particular, to a Virtualized Network Function (VNF) registration method, apparatus, medium, and device.

Background

By means of general hardware such as x86 and the like and virtualization technology, the NFV network decouples software and hardware and abstracts functions, so that functions of network equipment do not depend on special hardware any more, flexible sharing of infrastructure resources is realized, rapid development and deployment of new services can be realized, and automatic deployment, elastic expansion, self-healing and the like can be performed based on actual service requirements.

During the lifecycle management of a Network Service (NS) or VNF instance, dynamic adjustment of the virtual network may be achieved through policy control, such as adaptive adjustment of the virtual network size according to traffic load.

At present, in most systems adopting Network Function Virtualization (NFV) technology, a separate data collection module and a policy module may be abstracted, where the data collection module is responsible for collecting data such as system alarm/performance during operation, and the policy module is responsible for maintenance, distribution and operation of policies. The policy rules are usually predefined, or defined in the service template in the design state, and then imported into the policy module of the operating state system, and the operating state policy module may match the policy imported in advance according to the received data, and adopt corresponding policy control, for example, when some system abnormality is detected, a virtual downtime or VNF performance data exceeds an expected threshold, the matching policy performs a virtual machine restart or VNF capacity expansion.

In the existing VNF implementation, a design state needs to design and upload a policy, and the policy is distributed to a policy module for policy control in an operating state, and data collection is completed by a data collection module in the operating state, and some system operating state data collection modules further have a data subscription process before data collection to subscribe to a type of data desired to be received. However, the definition of the policy is actually closely related to specific data or events, and in the existing implementation scheme, two related steps are split into a design state and an operating state, so that the effectiveness of policy control is difficult to guarantee.

Example one

An embodiment of the present invention provides a VNF registration method, where a flow of steps of the method may be as shown in fig. 1, and the method includes:

step 101, receiving a VNF packet.

In this step, a VNF package may be received, where the VNF package includes a VNF registration file, and the VNF registration file includes a data definition part and a policy part.

It can be understood that this embodiment provides a new-format VNF registration file including a data definition part and a policy part, and the VNF registration file may be carried by a VNF package.

The data that the VNF described in the data definition section may generate may be understood to include, but is not limited to including, performance data and/or alarm events.

A summary (schema) description of the VNF registration file may be as shown in table 1 below:

TABLE 1

/>

An example of a VNF registry file based on the schema definition shown in table 1 may be shown in table 2 below:

TABLE 2

And 102, analyzing the VNF registration file.

In this step, after receiving the VNF package, the VNF registry file in the VNF package may be parsed to obtain the data definition part and the policy part in the VNF registry file.

It should be noted that, the path of the VNF registration file in the VNF package may be described by using an extended event registration (eventreistration) field in a network function module descriptor (VNFD).

The eventreistration field definition can be as shown in table 3 below:

TABLE 3

It is understood that the VNF registration file is defined in the VNFD and then uploaded to the service design application (VNF registration apparatus) in the design state through the VNF package uploading process.

At this time, the step may be understood as including: and analyzing the path of the VNF registration file described by the eventreistration field in the VNFD in the VNF package, thereby realizing the analysis of the VNF registration file in the VNF package.

Step 103, distributing data and policies.

In this step, the data definition part in the VNF registration file obtained through analysis may be distributed to a data collection module in an operating state, so that the data collection module performs data collection according to the data definition part, and the policy part in the VNF registration file obtained through analysis is distributed to a policy module in the operating state, so that the policy module performs policy control according to the policy part.

It should be noted that the data possibly generated by the VNF described in the data definition part may also be understood as a data format including the data possibly generated by the VNF, so that after the parsed data definition part is sent to the data collection module, the data collection module may also perform data format verification according to the data format of the data possibly generated by the VNF described in the data definition part.

It should be further noted that, in a possible implementation manner, before distributing the policy part in the VNF registry file obtained by parsing to the policy module in the running state, the method may further include step 103':

step 103', policy optimization.

In this step, the policy part in the VNF registration file obtained by the analysis may be optimized. Policy optimizations may include, but are not limited to: and modifying a threshold value, combining strategies and other strategy optimization modes. If step 103' is performed, the optimized policy portion may be distributed to the policy modules in the run state in step 103.

In a possible implementation manner, before performing policy optimization, step 103 ″ may be further included:

step 103", determine if policy optimization is required.

If it is determined that policy optimization is required, step 103' may be performed, otherwise, step 103 may be performed directly.

The inventor of the present invention finds that, in an NFV scenario, a data provider is usually a VNF vendor, and besides knowing data that the VNF of the VNF can generate, the VNF vendor is also very familiar with how to adopt a policy when some data exception or exception alarm occurs. If the policy control is executed based on the data provided by the VNF vendor and the corresponding policy, the network control and the network adjustment can be better performed.

Therefore, in the solution proposed in this embodiment, a new VNF registry file format is proposed, which includes a data definition part and a policy part, and a distribution process of the content of the design-state VNF registry file to the run-state VNF can be implemented, so that the run-state data collection module can collect data according to the data definition part, and the run-state policy module can perform policy control according to the policy part. In addition, a description of the design-state VNF registry may be introduced in the eventreistration field in the VNFD model.

In this embodiment, by adding a design-state VNF data registration function, both data registration and policy import are completed in a design state, so that an operation-state data subscription process and a design-state policy import process are simplified. And the VNF data registration function combines the VNF data and the proposed policies, making the policy definition more accurate. And the data definition part in the VNF registration file is distributed to a data collection module in operation, and the data collection module can also check the data format in operation according to the data definition part.
