Jinan Metro Optical Transport Network Planning And Design

Through the trasportation network large scale builds of the mobile company over the past few years, backbone network, MAN begin to take shape already. Upper great quantity applies of DWDM and 10 Gbit/sSDH in backbone network, problem of system capacity has already got fairly good solved. Think that the 3G starts construction soon at the same time, it should shift to an earlier date being in progress of the supporting trasportation construction for 3G.Therefore, the build priority is MAN.At present MAN transfer main part voice business such as base stand and line for special use cut-over, the data business such as CMNET/GPRS VPN cut-over as representative increase prompt, compared with the traditional voice service , data business rate of flow, flow direction are more complicated, the request to bandwidth, security is also varied. NGN network is under rapid development, and 3G mobile communication supporting data transaction will be introduced very soon, all of which require MAN should be a uniform platform, and it can transfer vairous transaction enficiently and in secure. Thus it is demanded that MAN product can support multiple data interface, and enhance transferring enficiency, while guaranteeing voice service supportable.These years the replacement of fixed phone with mobile phone is becoming more and more obvious, and mobile servie still in rocketing, its network is getting huger, and it requires bigger and bigger capacity of MAN. Therefore, JinanMobile MAN optical transfering networking is establishing their networking based on the fact that voice service is the main profit source of mobile bissiness, as well as considering the rapidly developing data transaction, choosing apropriate net solutions, and establishing MAN optical transportation network suitable for mobile business development.The paper has discussed the concept of MAN, structure and several kinds group net technology first, introduced the technology of SDH, WDM, MSTP. By analysing the business type of the MAN, it introduced the development plans of JinanMobile's every business net (voice, data and customer of Corp. cut-over) and provides the need of transferring passage to MAN. It also discussed the group net structure and principle of MAN under construction. Based on JinanMobile's current situation of MAN and business development the paper forecast the need of transferring passage, having ascertained JinanMobile's MAN Optical Transportation Network construction scheme for 2006 (network structure and scale). The construction scheme have already part be put into effect. It brought the important effect on the fleetness develops of various company business (voice, data) and have reached purpose and effect of guiding network construction. The paper also having carried out a summary of the accomplishing construction's tune measures result.
