Design And Implementation Of Mobile Metropolitan Area Network OTN Network

The demand for today's communication networks is constantly changing,carrying large volumes and diversity of services,and further increasing the security and flexibility requirements of the network.The limitations of SDH(Synchronous Digital Hierarchy)and WDM(Wavelength Division Multiplexing)networks are increasing.OTN(Optical Transport Network)optical network transmission technology can meet the needs of large bandwidth and high-speed services,flexible scheduling,combine the advantages of WDM and SDH technologies,and have more advanced management capabilities.Therefore,OTN technology is currently available.used widely.In the mobile metropolitan transport network,the OTN technology is mainly applied to the core layer and the convergence layer of the metropolitan transport network.The paper analyzes the existing OTN network of mobile metropolitan area network,and puts forward the problem of metropolitan area network OTN one-plane network,highlighting the necessity of constructing the second-plane network of metropolitan area network OTN.The functions and technical requirements of the mobile metropolitan area network OTN network are introduced.The mobile metropolitan area network(OTN)network design was developed from the aspects of network capacity planning,site type planning,optical cable resource determination,network topology planning,network management planning,protection planning,channel planning,and system parameter planning.In order to verify the feasibility and effectiveness of the design scheme,the design scheme was planned and implemented in the Kashgar area.After the implementation of the second-plane network design scheme of the OTN of the Kashgar metropolitan area network,the functions and technical indicators of the system were verified and tested.The technical indicators have passed the test,and the service bearer function and network security function have been realized.The support and support capability of the Kashgar metropolitan transport network at the core convergence layer has been improved,and the OTN network of the Kashgar metropolitan area network is more secure,reliable and sturdy.The verified scheme is feasible and effective.The mobile metropolitan area network OTN network design solution can meet the business development of the metropolitan area network and the service security requirements.It can optimize the network structure and improve the robustness of the network.The local metropolitan area network OTN can be designed and built with reference to the mobile metropolitan area network OTN network.Two-plane network.
