Study Of Expansion And Optimization For Guangdong Tietong Transmission Networks

This paper mainly introduces the project of expansion and optimization about theGuangdong TieTong transmission network.After the reorganization of the telecommunications industry in2009, part of thetransmission network and optical cable resources allocable to the Ministry of Railways. In thiscase, the rapid development of business has brought great pressure to the Guangdong TieTongtransmission network, and also exposed many problems. As the telecommunication operationenterprise, basic transmission network is the lifeline of the enterprise, it decides the operationcost and the quality of network service and other core issues, but it is also the important basicconditions to improve the comprehensive competitiveness of enterprises. After many years ofbusiness development and system operation, part of the transmission network exposed someproblems, the network has been unable to fully meet the demand, and limited the developmentof telecommunication business. So the transmission network evaluation and optimization iscrucial.Firstly, this paper introduces the situation about a comprehensive self-examination andassessment analysis for the Guangdong transmission network, put forward the existingproblems about the network. It includes some node opened business inconvenience, becauseof the south central SDH system allocated to the railway, like zhuhai and zhongshan. And thesource tension in the East, West SDH system and the local interconnect ring, part nodes tendsto saturation; the north DWDM system is a no protection chain, which is a hidden trouble,leading the internet business security problems, this business is form shaoguan,qingyuan toguangzhou.Then according to the prediction of Guangdong TieTong customer business development,have a estimation of the business needs, and analy the existing network whether meet. andaccording to the network problems, business needs, different equipment manufacturers aswell as the comparison of existing resources and investment circumstance, design theGuangdong transmission network expansion optimization scheme.it includes building somenew systems, the Guangzhu DWDM system, the Guangzhan DWDM system, and the SDHsystem from guangzhou to Shantou, Shaoguan, Qingyuan, and the ring networktransformation about the local interconnect.Finally, after the implementation, the project results are analyzed; The project is verysignificant effect, the problem about the resource issues of the whole network have beenalleviated, the resource in the East SDH system and the West SDH system has been released; the business security from Guangzhou to Qingyuan, Shaoguan has improved; at the same time,the overall network capacity has been expanded, which can meet the growing business needsin recent years, it is the basic guarantee for company’s development.
