Description

A VNF registration method, apparatus, medium and device

technical field

The present invention relates to the technical field of network function virtualization (NFV), and in particular, to a virtualized network function (VNF) registration method, apparatus, medium and device.

Background technique

NFV network relies on general hardware such as x86 and virtualization technology, through software and hardware decoupling and functional abstraction, so that network device functions no longer depend on dedicated hardware, and realizes flexible sharing of infrastructure resources, thus enabling rapid development of new services. and deployment, and can perform automatic deployment, elastic scaling, self-healing, etc. based on actual business needs.

During the life cycle management of a network service (NS) or VNF instance, the dynamic adjustment of the virtual network can be realized through policy control, for example, the virtual network scale can be adaptively adjusted according to the service load.

At present, in most of the systems using Network Function Virtualization (NFV) technology, a separate data collection module and policy module can be abstracted. The data collection module is responsible for data collection such as system alarms/performance at runtime, and the policy module is responsible for policy maintenance. , distribute and run. Policy rules are usually pre-defined, or defined in the service template during the design state, and then imported into the policy module of the running state system. The running state policy module can match the pre-imported policy according to the received data. Take corresponding policy control. For example, when certain system exceptions are detected, the virtual machine is down, or the VNF performance data exceeds the expected threshold, the policy is matched to restart the virtual machine or expand the VNF.

In the existing VNF implementation scheme, the design state needs to design and upload the policy, and distribute it to the policy module for policy control in the running state, while the data collection is completed by the data collection module in the running state, and some systems run state data. The collection module will also have a data subscription process before data collection to subscribe to the types of data that you want to receive. However, in fact, the definition of a strategy is actually closely related to specific data or events. In the existing implementation scheme, the two associated steps are split into a design state and a running state, which makes it difficult to guarantee the effectiveness of policy control.

Example 1

Embodiment 1 of the present invention provides a VNF registration method. The step flow of the method may be as shown in FIG. 1 , including:

Step 101: Receive a VNF packet.

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

The data definition part is used to describe the data that may be generated by the VNF, and the policy part is used to describe the corresponding strategy to be taken when the data that the VNF may generate is abnormal or meets a set threshold condition.

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

The data that may be generated by the VNF described in the data definition part may be understood to include, but not limited to, performance data and/or alarm events.

The schema description of the VNF registration file can be shown in Table 1 below:

Table 1

An example of a VNF registration file defined based on the schema shown in Table 1 can be shown in Table 2 below:

Table 2

Step 102: Parse the VNF registration file.

In this step, after receiving the VNF package, the VNF registration file in the VNF package may be parsed to obtain the data definition part and the policy part in the VNF registration 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 (eventRegistration) field in the network function module descriptor (VNFD).

The eventRegistration field definition can be shown in Table 3 below:

table 3

It can be understood that after the VNF registration file is defined in the VNFD, it is uploaded to the service design application (VNF registration device) in the design state through the VNF package upload process.

At this time, this step can be understood as including: parsing the path of the VNF registration file in the VNF package described by the eventRegistration field in the VNFD, so as to implement parsing of the VNF registration file in the VNF package.

Step 103: Distribute data and policies.

In this step, the data definition part in the VNF registration file obtained by parsing can be distributed to the data collection module in the running state, so that the data collection module can collect data according to the data definition part, and analyze the obtained data The policy part in the VNF registration file is distributed to the policy module in the running state, so that the policy module performs policy control according to the policy part.

It should be noted that the data that may be generated by the VNF described in the data definition part can also be understood to include the data format of the data that the VNF may generate. The data collection module may also perform data format verification according to the data format of the data that may be generated by the VNF described in the data definition part.

It should be further explained that, in a possible implementation manner, before distributing the policy part in the VNF registration file obtained by parsing to the policy module in the running state, step 103' may also be included:

Step 103', strategy optimization.

In this step, the policy part in the VNF registration file obtained by parsing may be optimized. Policy optimization may include, but is not limited to: modifying thresholds, policy merging and other policy optimization methods. If step 103' is executed, in step 103, the optimized strategy part may be distributed to the strategy module in the running state.

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

Step 103", determine whether strategy 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 this case found that in the NFV scenario, the data provider is usually a VNF manufacturer. In addition to knowing the data that can be generated by their own VNF, the VNF manufacturer is also very familiar with how to adopt strategies when certain data abnormalities or abnormal alarms occur. If the policy control is performed based on the data provided by the VNF vendor and the corresponding policy, network control and network adjustment can be better performed.

Therefore, in the solution proposed in this embodiment, a new VNF registration file format including a data definition part and a policy part is proposed, and can realize the distribution process of the content of the VNF registration file in the design state to the running state, so that the data collection module in the running state can be implemented. Data collection can be carried out according to the data definition part, and the running state policy module can carry out policy control according to the policy part. In addition, the description of the design state VNF registration file can be introduced in the eventRegistration field in the VNFD model.

In this embodiment, by adding a VNF data registration function in the design state, data registration and policy import are completed in the design state, which simplifies the data subscription process in the running state and the policy import process in the design state. And the VNF data registration function combines VNF data and suggested policies to make policy definition more accurate. And the data definition part in the VNF registration file is distributed to the runtime data collection module, and the data collection module can also perform runtime data format verification accordingly.
