Design Of Network Orchestration Platform Of 5G Scenarios

The deployment of 5G networks in industrial Internet needs to be integrated with specific industrial scenery.The network-proof platform of existing telecom operators is targeted by the public business,and the industrial environment is facing different business scenarios.In order to meet the network-proof needs of the business scenes in industrial Internet,the existing telecom operators' 5G network arrangement platform needs Meet the capacity of network arrangement based on the scene in industrial Internet environment to achieve "vertical" deployment of OICT fusion in industrial Internet.To this end,this thesis is designed and implemented a network-proof platform for 5G scenes.The main work is as follows:(1)This thesis analyzes the relevant technologies of the existing telecom operators' scene orchestration platform,and designs the architecture of 5G network scene orchestration support platform based on the architecture of telecom operators' scene orchestration platform.The platform uses the "layered NFVO" structure in ETSI NFV,and the platform is connected to the top-level scenario platform,and the network-proof management platform provided by the Os-ma-nfvo interface is connected to the platform to make this platform to schedule global resources.The ability to design business templates according to specific scenes.(2)There is a large number of various levels of templates and objects adapted to different scenes in the support platform of 5G network scenes.To enhance the management of business templates,network slice templates,network service templates,virtual network function templates,and corresponding object instances.Fast search for templates and object instances,design template and instance management functions.The template and object instance files in the platform are described in YAML format.The file contains the basic information of the template and the object instance.The naming of the template and the object instance is designed with the hierarchical naming scheme.Designed the scenario support platform and The information interactive interface between the underlying MANO,and uses multiple keyword text search algorithms to achieve fast search findings for templates and instances.(3)According to the supporting platform architecture of 5G network scene arrangement,this thesis studies the 3GPP NMS network management protocol.The protocol processes,such as VNF template subscription process,VNF template information query process,VNF template acquisition process,VNF instantiation process,VNF automatic capacity expansion process,VNF instance termination process and NS deployment process,were redefined.(4)This thesis uses the OSM open source platform for software implementation schemes for 5G network scenario supporting platforms,and verifies the related functions.Platform implementations include platform scheme design,logical architecture,platform interface design,development architecture design,and platform function verification.Platform feature verification introduces the verification environment and demonstrates the verification process and results of the relevant functions through the interface.
