Design And Implementation Of NFV-based Virtualized CPE Template Recommendation Deployment System

Existing Virtualized Client Equipment(CPE)based on Network Function Virtualization(NFV)environment can replace existing physical CPE,thereby reducing deployment costs,and researching its recommended deployment system can further improve the efficiency of virtualized CPE template configuration..Therefore,researching the NFV-based virtualized CPE template recommendation deployment system is of great significance for practical applications.There are two main problems in the research of existing virtualized CPE templates.On the one hand,most of the existing template configurations are manually configured,and the configuration efficiency is low;on the other hand,most of the previous researches have focused on the study of a functional template or a specific scenario of a virtualized CPE virtualized network function(VNF)template,which lacks versatility.Aiming at the above problems,this paper proposes a general virtualization CPE template recommendation algorithm based on NFV technology.Further,based on the above algorithm,the template deployment system is designed and implemented.The system can automatically identify the topology information of the devices connected to the network,the usage of the device,and the network information,and automatically generate a recommendation template based on the information and deploy the template according to the selected template.The specific research contents of this topic are as follows:Firstly,a VNF function template recommendation algorithm based on fuzzy comprehensive evaluation method of analytic hierarchy process is proposed.The parameters of each VNF function template are aggregated,the weights are calculated,and the value of each template parameter is recommended and saved as a template.Secondly,based on the above proposed algorithm,this paper designs and implements a NFV-based template recommendation deployment system.The system determines the network topology and device status according to the connection relationship and access status of the relevant access device.At the same time,the system invokes the template generated by the recommendation algorithm,implements the visual editing configuration template,and delivers the deployment template.The experimental results show that the recommended algorithm can effectively improve the low efficiency of manual configuration of templates,generate recommended templates quickly and efficiently,and the recommended algorithm can support multiple VNF function templates,and the versatility is significantly improved.The recommended deployment system designed and implemented in this paper can effectively improve the efficiency of the overall template configuration.It is convenient for management personnel to manage and maintain more devices,and can deploy templates with different parameters according to different conditions of the device to complete the deployment function.
