Problems solved by technology

However, the current standard only defines the VDU information included in the VNF deployment specification. For the network connection in the VNF, the dependency relationship between VDUs, automatic scaling policies, life cycle events, and monitoring parameters are not defined. It will result in a lack of flexibility when VNFs are instantiated according to specified specifications

Embodiment Construction

[0101] In order to make the purpose, technical solution and advantages of the present invention more clear, the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined arbitrarily with each other.

[0102] The technical problem to be solved by the present invention is that when deploying VNF, users have performance requirements for VNF such as capacity and processing capability. In order to meet this requirement, VNFD is required to provide multiple optional VNF deployment specifications. In addition to providing the constituent VDUs, the VNF deployment specification also needs to provide customized options for connection points, dependencies between VDUs, virtual link VL attributes, automatic deployment strategies, parameter monitoring, and VNF lifecycle event script exe...

Abstract

The invention provides a method and device for realizing virtual network function deployment specification configuration. The method comprises the following steps: receiving an instantiation request of a virtual network function VNF, wherein the instantiation request carries a virtual network function identifier VNFD and a VNF deployment specification identifier; and carrying out instantiation processing of the VNF according to the VNFD corresponding to the VNFD identifier and a VNF deployment specification corresponding to the VNF deployment specification identifier, wherein the VNFD describes one or more VNF deployment specifications and one or more configuration description information for the selection of the VNF deployment specification, and the VNF deployment specification comprises one or more configuration description information. By adopting the method and device provided by the invention, the VNFD can provide a flexible mechanism, different formulation functions are provided for a VNF developer and a VNF deployer during the VNF deployment of multiple specifications, and artificial intervention and uncertain factors in the VNF deployment process are reduced.

Description

technical field [0001] The present invention relates to the technical field of network function virtualization, in particular to a method and a device for realizing virtual network function deployment specification configuration in an operator's network function virtualization environment. Background technique [0002] With the development of telecommunication network functions and services, more and more types of network elements are deployed in the network. The increase in the type and quantity of network elements has brought many problems, such as various types of hardware platforms and complex maintenance; hardware cannot be shared, resulting in waste of resources; new services require support from new hardware platforms, increasing service time to market (TTM), etc. [0003] In recent years, cloud computing technology has developed rapidly, and cloud computing technology can effectively reduce construction and operation and maintenance costs. Cloud computing hardware p...
