Research And Development Of Automatic Operation System For SDWAN Network

In recent years,with the rapid development of the SDN technology,applications relying on SDN technology emerges rapidly.Equipment manufacturers launch new devices to support the SDN.In the wide area network more and more operators reform and optimize their network based on SDWAN technology.The new network architecture represented by SDWAN has been applied in more and more fields.However,the rapid development of SDWAN network has introduced new problems,including how to break the bottleneck of operation and maintenance efficiency.In this paper an operation automation system for SDWAN was proposed to solve this problem.Firstly,through introducing the status quo of operation automation system,the advantages and the shortcomings of the mainstream architectures of operation systems and their corresponding technologies were analyzed,which provided a valueable reference for the design of SDWAN operation automation system.Secondly,according to the requirements of the SDWAN operation,four key technologies were researched in depth:(1)the structure of operation automation system;(2)the configuration and management automation technology;(3)the network monitoring technology based on active measurement;(4)the SDWAN log monitoring technology.Thirdly,with the system design and combined with the requirements analysis,the proposed SDWAN operation automation system was divided into four modules:the automated configuration management module,the monitoring module,the log module and the database module.The design and development of each module were also introduced in detail.Finally,the stability and efficiency of the SDWAN operation automation system were verified by extensive testing.
