Streaming Media System Design And Implement For Telecom Operation Layer

The advance of world communication technology, comes through the stages as the invention of communication technology, telephone network, analog communication, as well as digital communication. Recently, the contradiction between modern communication and tradition telecom is becoming increasingly acute. For the applications of EMAIL and P2P dialog software that is based on network for MSN and QQ, there are characteristics of both universality and convenience, which has taken a great party of service distributary to tradition telecom. With the state of increasing service but not increasing profit in fixed-line telephones for a long period, telecom operators has to search for a new service increasing approach of rich value-added services to attract customers since 2000. Consequently, the content services are becoming the "blue sea" for the telecom operator advance. The video service is one of favorable value-added services for customer. For this reason, the streaming media system design and implement is profound in the paper.In general, the construction and operation of streaming media system is divided as two types, one is a mini-system that is invested and operated by ISP, the other is a large network that is invested and operated by telecom operator.From the source provider, the source layers of streaming media system consist in application layer, foundation layer, network processing layer as well as source storage layer. The primary protocols are RTP/RTCP,RTCP,etc. The key technologies are soft-tactical content distribution, optimization load balance algorithms , second certification, content share, as well as interface technology.With network merge is a forever topic for net advance in future, communication network is advancing in multi-network merge to provide various rich business for customer. As a result, streaming media system is the advance of value-added service for operator.Fujian network communication Co. Ltd that is a new telecom operator, design and implement a distribution streaming media system to meet the increasing customer and business expend. Two nodes of the system have been constructed both in Fuzhou and Xiamen.The key of a technology succession is in its business function and operation mode. In this paper, system business function such as management, support and process, has been explained in the implement of Fujian network communication streaming media system, which is also analyzed for system operation with value chain.During the implementation process of the Fujian Unicom streaming media system, I took part in the system performance, business functions, the analysis of the operation mode and the system.
