Design And Optimization Of Nanchang Radio&Television IP Man

As the process of integration for Broadcasting TV net(BTN),Telecommunication net and Internet Continuously pushing forward at present,Broadcasting TV industry works actively in network integration,and have already started to develop the China's Next Generation Broadcasting Network(NGB)since2008.NGB includes three parts which are national backbone network,MAN(metropolitan area network)and access network.Among them,MAN of various Broadcasting TV operators are connected by national backbone network after integration and constitute part of the NGB.The research work of the thesis is based on the above background.The thesis includes the following content:1.Based on the analysis the status of the Nanchang Broadcasting TV MAN,we research the relevant technology of IP MAN construction according to NGB general technical framework.In the same time,we meet the business requirements of Nanchang Broadcasting TV MAN and identify the basic principles and construction ideas of Broadcasting TV IP MAN.At last,we put forward the solutions for the construction of Nanchang Broadcasting TV IP MAN after researching and analyzing IP MAN Networking mode,device configuration,and network design and planning.2.We have implemented Nanchang Broadcasting TV IP MAN upgrading project according to its network construction.In the project,we adopt the most advanced Cluster-based router technology,OTN transmission network technology,EPON access network technology and Dual Hot-backup and centralized authentication technology for upgrading and improving backbone network,access network and transmission network of metropolitan.Finally,a new Nanchang Broadcasting TV IP MAN has been built.Through our research and practice,we successfully complete the Nanchang Broadcasting TV IP MAN upgrading project and pointedly solve the existing bottleneck problem of MAN.The upgraded Nanchang Broadcasting TV IP MAN is broadband communication,IP based,total exchange and T-stage transmission,which conforms to NGB general technical framework and meets the trend of "triple-play".It would be some useful reference of present IP MAN construction for Broadcasting TV carrier operators in other regions.
