The Design And Implementation Of NFV-Oriented Operation And Maintenance System

There are too many types of hardware devices used by network operators to build networks.They often need to add new devices because of the development of new services.This increases the cost and the complexity of hardware-based devices is greatly increased.And it is extremely difficult for design,integration and operation,so NFV(Network Function Virtualization),which can decouple hardware and software,has emerged.With the advent of the 5G era,the company has new requirements for NFV technology.The operation and maintenance systems and manual operation and maintenance methods used in the past have been unable to meet the requirements.Therefore,Huawei has developed a NFV-oriented operation and maintenance system to reduce the cost of operation and maintenance,improve operation and maintenance efficiency,accurately locate problems when faults occur,and realize visualization and control of network maintenance information.This paper expounds the research background and significance of the NFV-oriented operation and maintenance system of Huawei Technologies Co.,Ltd.It summarizes the current situation and measures of the intelligent operation and maintenance system,and combines the internal health monitoring framework of the company to explore a new construction plan of the NFV-oriented operation and maintenance system.Based on the research,this paper carries out the following work around the design and implementation of NFV-oriented operation and maintenance system:1.Analysis and research on existing intelligent operation and maintenance systems and frameworksAnalysis and research of intelligent operation and maintenance systems at home and abroad,including open source operation and maintenance tools Nagios,Ali’s Hawkeye system,Huawei’s internal intelligent operation and maintenance system e Service,and data center network analyzer Fabric Insight,etc.2.System analysis and design based on Huawei intelligent operation and maintenance frameworkBased on the research above,combined with the existing intelligent operation and maintenance framework within the company,the system is divided into five modules:system management module,data acquisition module,data analysis module,data management module,and interface visualization module.And it was analyzed and designed the application situation and specific business requirements of NFV.3.Specific implementation of some modules of NFV-oriented operation and maintenance systemBased on the requirements analysis and design,the specific implementation of the data acquisition module,data distribution module,and data management module is mainly described in detail,and detailed codes are attached for explanation.The operation results show that the system can be used effectively.
