Feasibility Study Report Of Large Bandwidth Cmnet

With the fast development of Chinese economy and the big advancement of information technology, people need much more information. The all IP and large broadband network structure, restructure the transmission network to the direction of high speed, high stability, and powerful supporting ability. Such as the GPON technology, the PTN technology and the OTN technology, there are some new kinds of transmission network technology emerge in this context.The article introduces the backgrounds, the characters and the network structures of three kinds of new mainstream technology (the GPON technology, the PTN technology, and the OTN technology) particularly, which are the good support to the transmission network, and analysis the facilitation of the new technology to the CMNET network specially.Based on the development of CMNET business and the current situation of the transmission network of the Brach Company in Hohhot of CMCC, the article analysis the strength of the transmission network and the bottleneck of developing the CMNET business deeply, to improve the necessity of building the GPON network, the PTN network, and the OTN network to the company.From the development of CMNET business and the current situation of the transmission network, the article analysis the support ability of the transmission network to the CMNET business particularly, and confirms the network construction scheme. At the same time, the article discusses the GPON technology, the PTN technology, and the OTN technology in details, and designs the network construction project. At the last, the article evaluates and summarizes the effect of the project, and makes an expectation of the development of the transmission network technology in the future.
