Zhengzhou Transmission Network Technology Development And Application Of MSTP Technology

Along with the diversification of the business layer,the net project based on SDH appeared in the optical transport network,Its basic way of thinking is to establish an unify Multi-Service TransportPlatform(MSTP), to content different customer increases increasingly high to take the request of the breadth,many business.So-called MSTP,it is a kind of optical transport network node equipment that various business characteristics proceeding handles.It has primarily below some characteristics:Have a batch of connects based on the requests of SDH system,include to multiplexing,pointer,cross,mapping..etc.The MSTP can not only realizes the TDM business connect into,but also join at the same time the ATM,IP..etc.Business connects into with handles;the whole platform is placed in the united network management system management under. MSTP be evloved by traditional SDH.The basic thinking of one platform loading many business was gradually approved by the large telecommunications services and equipment manufactories,there have been more and more the products and solutions of MSTP gradually applied in the developments of metropolitan area network and local communications network. The new generation MSTP node based on SDH can support all the functions of traditional SDH equipments,intergration level is higher,the cross ability is stronger and the network management system function is more perfect. Therefore,the MSTP inherites and develops nicely the aspects of network application,supports more complicated toplolgical graph to adjust business is more vivid.At the same time,because of a many business for having loading ability,the especially abundant data business loads the ability,MSTP makes its network application present a series of new characteristics again.These put forward a new lesson how to design and peograme the MSTP local communications network engineering based on SDH. This thesis synthesizes the related design norms and profession standards,the basis is the actual experience to design and development native network engineering in recent years,combining the MSTP engineering applied in the domestic mobile phone operator local communications network that was provided by Fiberhome Telecommunication Technologies Co.Ltd.,expatiates the MSTP design thoughts and principle based on SDH in native transport engineering.
