NFV network element full-surrounding test method and device based on digital twin technology

Abstract

The invention relates to an NFV network element full-surrounding test method and device based on a digital twin technology. The device comprises an NFV service system module, an NFV network element surrounding test module and an intelligent scoring module, and the method comprises the following steps: firstly, constructing the network element surrounding test module, and establishing a virtual-real mapping relation between the service system module and the network element surrounding test module; secondly, carrying out network element simulation, service process customization and message simulation, constructing a dynamic telephone traffic model, carrying out index statistical analysis in a network element surrounding test module, and transmitting the statistical indexes to the intelligent scoring module; comprehensively evaluating the network element through an intelligent scoring module, obtaining a network element evaluation result, and feeding back the result to an NFV network element surrounding test module; and finally, applying the scoring data to the network element operation and maintenance of the existing network to help to complete the actual service operation and maintenance work. According to the invention, simulation of the operation environment of the existing network service can be completed in the test stage, and the tested service is verified by using real data.

Description

technical field [0001] The invention belongs to the field of new-generation information technology, specifically relates to technical fields such as information communication, NFV / SDN, digital twin, machine learning, etc., and is a method and device for fully enclosing testing of NFV network elements based on digital twin technology. Background technique [0002] NFV stands for Network Function Virtualization. By using general-purpose hardware such as x86 and virtualization technology, software processing of many functions is carried. Thereby reducing the expensive equipment cost of the network. Through software and hardware decoupling and functional abstraction, network device functions no longer depend on dedicated hardware, resources can be fully and flexibly shared, and rapid development and deployment of new services can be realized, and automatic deployment, elastic scaling, and fault isolation can be performed based on actual business needs and self-healing etc. ...

AI Technical Summary

Problems solved by technology

[0004] With the emergence of NFV / SDN technology and the evolution of 5G networks, the traditional mode of relying on proprietary hardware is gradually becoming software-based. Compared with traditional networks, the NFV network architecture is more complex. There is mutual cooperation and influence between unit modules, which further leads to the instability of the overall network element
