Application On CDN Technology In Shanghai Telecom Value-added Broadband Business

With the development and construction of broadband competition,broadband application becomes core of competition. The appearance ofstreaming media and broadband content delivery network technology offerstechnology support base for application of broadband network. The coretechnology of streaming media is streaming technology and highcompression, which enable multimedia provide with service as playingwhen downloading. In that case, the rigid content form of traditionalnetwork is totally changed. The video program with strong visual impactbecomes one of the major applications for people get into broadbandnetwork. The telecom operators want to consolidate the original networkcommunication market through the development of streaming mediatechnology and broadband network, as well as getting into the emergingnetwork media entertainment market. The traditional network operatorsdo not have radio and television transmission network. On the other hand,the broadband network and streaming media technology interactive and future development allow broadband operators see the opportunity andbright future of developing broadband interactive video. The streamingmedia changes the broadband industry, which becomes a consensus.Locally, in Shanghai, the construction of Shanghai telecom broadbandnetwork is matured. The number of broadband users is also increasedrapidly. It is conservatively estimated, local broadband users will bereached to1000000next year. So, it has been the top priority that tofurther expand based on CDN platform, fulfill network service, improveconcurrent user access capability and enhance the quality of service.Using software solution to establish CDN can realize all functions thatthe original hardware can realize, as well as seamless integration withhardware solution, to protect the operator’s investment. Using softwareprogram, can well solve the problems of high price of hardware, badcompatibility between equipments, high difficulty of a variety of device,and service quality during actual operations, which meets the operators’actual demand of CDN.I mainly take responsibility of CDN network subsystem. Thissubsystem includes load balancing, caching services, authentication and accounting gateway, content management services. As the underlyingresources, these equipments and service offers bottom support for uppermanagement system.
