OTN Network And Research Of Application In Huhhot Telecom

The bandwidth of data service, the base station return network and access network demands to promote the rapid growth of traffic in communication network, to gradually occupy the dominant large particle data representative of GE/10GE, put forward higher request rates, capacity and reliability of the transmission network.The limitation of traditional network in scheduling, protection, management and so on, such as SDH,MSTP,WDM technology, can not fulfill the demand of transmission network in future. Optical transmission network (OTN) is a new generation of ITU-T recommendations optical transmission system, and fully integrate the light field and the electric field processing advantage, which can provide transmission capacity, huge completely transparent end-to-end wavelength/sub wavelength connection and protection of telecom level OTN is the transmission of wideband large particles business technology optimization the current transmission network, and is also the hotspot of research and application.The thesis of OTN in Hohhot telecommunication network planning and security technology research. Firstly, the paper sketches information of OTN, such as the background, basic principle and main technology.The paper also introduces the architecture of OTN, and elaborates the hierarchical structure, the standard framework, the methods of mapping and multiplexing step by step. Then, considering the network model and service access mode feature of the OTN network technology, the paper analyzes and gives a scheme of Hohhot Telecom OTN. The paper has also studied the OTN technology of network security, including protection, synchronization and network management etc., on the basis of theoretical analysis combined with the practical engineering Hohhot Telecommunication is given the specific design scheme.
