The Transformation Of Jinan Broadband Metropolitan Area Network

Economic globalization and the emergence of knowledgeeconomy, promoting the rapid development of telecommunications .The rapiddevelopment of information and network technology with an unprecedenteddepth and breadth of change in all aspects of human life. Internet is to meet thegrowing demand for telecommunication, use advanced switching ,transmission ,xDSL and other high-speed access technologies to provide voice,data, image and other multimedia platform.Currently,China Netcom Company's IP (not include VoIP) business bearingby China169 and CNCnet. But the two sets of network is overlapping , theresources is not only effective use , but also cause a lot of interconnection costs,so the group established the IP network biplane development strategies, namely :the future of the IP backbone network consists of two plane, China169 businessnetwork as a backbone network will unify all bearing ordinary Internet business,CNCnet as MPLS backbone network . MAN backbone network as two of thelocal extension of the business, is the platform of the access and retention.:ailMPLS VPN QoS requirements of business customers and specific businessCNCnet backbone network will be carrying.and the provincial network ? MANas a local extension of the backbone network, the QoS building, operating,maintaining, bearing network can be managed more business to fit in with itsbusiness . Jinan, as the capital city of Shandong Province, is at thecenter of telecommunications network facilities in the province. Jinan CNC'sbroadband IP network quality is not only related to the developmentof local city , but also equally to the entire scientific network of ShandongProvince. Jinan is one of the pilot cities of China Netcom IPTV business. Inorder to adapt to new business, Jinan Netcom effort will be required to buildand develop ICT infrastructure and to enhance capabilities and the technicallevel, built a leading digital city in information and telecommunicationsnetwork, to create a "digital Jinan", and to provide advanced, safe,stability of the information and communication service network platform.This paper based on the development status of Jinan broadband business ,through the environmental analysis and development survey , explained themain problems. According to relevant technical information, in-depth study ofthe development trend of the future broadband business, determine the futureof the deployment process. According to business development and deploymentprocess, defined the guiding ideology of Jinan broadband MAN.According to the guiding ideology, determine the current transformation ofthe broadband network design ideas, including the characteristics of the currentMAN, evolution of the ideas and programs. According to its design ideas,principles and methods for determining the deployment of equipment.Meanwhile, analysis and rehabilitation the programs, and facilities underconstruction program to determine the size and configuration requirements,routing and address planning.Based on the Jinan MAN transformation program, depth verificate QoSimplementation and the realization of the operational mode. And analysis andverificate to network security, management, user authentication and supportfor the next generation network.
