Research On Evolution Scheme Of 5G-oriented PTN Metropolitan Transport Network

With the emergence of 5G network technology,the combination of metropolitan area transport network and 5G technology has become a research focus.According to the administrative region structure of "Six Districts and Three Counties" in Nanchang City,this dissertation proposes a 5G-oriented Packet Transport Network(PTN)metropolitan area transport network evolution plan based on the current status of Nanchang Education City Metropolitan Area Network.With the design of network topology,5G network technology and PTN Technology,the evolution plan of the 5G-oriented PTN Nanchang Education City Metropolitan Area Transport Network is suggested.First of all,the concept and technology feature of metropolitan area transport network?5G?PTN are overviewed in the text,which provide theoretical basis and technical means for the 5G-oriented PTN metropolitan area transport network evolution plan.And it furtherly analyze the feasibility and necessity of PTN metropolitan area transport network configuration through the introduction of 5G network technology requirements including large broadband,ultra-low latency,logical slicing,flexible connection,time synchronization,and unified management of SDN,which combined the requirements of the network architecture for the bearer,including the requirements for the bearer of wireless network services,home services and enterprise businesses.Then,the configuration information of specific device is proposed and the relay distance and cable information are described detailly based on the current status of Nanchang Education City Metropolitan Area Network and the network problem analysis.It propose the evolution plan of the PTN metropolitan area transport network through the network topology study,and also test and analyze the network and equipment performance.Finally,a network transformation plan is proposed for the next network expansion and upgrade,and the executable evolution plan for 5G-oriented PTN metropolitan area transport network is further determined.
