Construction method and device of VNF template

Abstract

The invention relates to the field of communication, in particular to a construction method and device of a VNF template. The invention is used for effectively improving system performance and improving processing efficiency, and comprises the steps of determining configured IE information according to deployment planning of a system, constructing JSON templates corresponding to the IE informationby adopting a preset data organization form, then converting the JSON templates by adopting a format converter preset by the system, respectively obtaining corresponding communication templates, andfinally, constructing a VNF template based on each obtained JSON template and the corresponding communication template. Thus, the JSON template and the communication template can be adopted for information interaction, different scene requirements are met, the management efficiency of the system is improved, the practicability and readability of the VNF template are improved, meanwhile, the purposes of reducing the code development amount of the system, improving the data processing speed and shortening the data processing time of the system are achieved, the maintenance cost of the system iseffectively reduced, and the practicability and readability of the VNF template are improved. System performance is improved.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and device for constructing a VNF template. Background technique [0002] A virtual network function (Virtualize Network Function, VNF) is a traditional physical network element that is deployed on a virtual machine under Network Function Virtualization (NFV) technology. The network elements are consistent. NFV management and orchestration (NFV Management and Orchestration, MANO) includes network function virtualization orchestrator (NFV Orchestrator, NFVO), virtualized network function manager (VNF Manager, VNFM) and virtualization infrastructure management system (VirtualizeInfrastructure Management, VIM ). NFVO is responsible for the overall management of network services, VNFs and resources, and is the control core of the entire NFV architecture. VNFM is mainly responsible for VNF resource and life cycle related management, such as network element instantiation, ...

Problems solved by technology

Later, a graphical method appeared, and the VNFD template was built by dragging and filling in the information in the graph. However, the cost of realizing the graphical method is relatively high, and the software implementation of the customized graphical interface tool is relatively complicated. Although the graphical method is convenient and intuitive, it is efficient. It is relatively low, and the process is relatively lengthy. It takes many steps to complete the construction of a VNFD after dragging and dropping a large amount of information in the interface.

[0009] Existing solutions use templates in XML format. Templates in XML format can be used directly by management and orchestration programs. The use of HOT templates has certain limitations. It can only be used for simple virtual machine deployment in the OPENSTACK HEAT service. TOSCA templates It cannot be used directly, and the information needs to be parsed out, but there is no uniform regulation on the Information Element (IE) contained in it.

[0010] Templates in XML format are suitable for communication between machines, and complex templates are difficult for humans to write and read

Templates in YAML format are easy to read manually, but difficult to write

These two templates are not universal and cannot be used with each other in different management and orchestration systems

The goal of HOT template and TOSCA template is to be common in different management and arrangement systems, but it is very difficult to manually write and read
