Study On Flattening Transformation Scheme Of Tieling Tietong Metropolitan Area Network

Flat network is based on the volume of business, breaking the network carriersconducted in the early administrative division, to achieve inter-regional convergence andreduce the level of aggregation and nodes in the interior of the core node, tandem node andedge node has overlapping node to a next level. Meanwhile according to network traffic, alledge nodes can be directly connected to the core nodes, sink nodes are directly connectedacross the region. Flattening of the network is the inevitable trend of development of thetelecommunications network, the entire network construction mode from the early levels ofthe professional network to transition, but also the next generation network requirements.Flat network architecture, in theory, can effectively improve the telecommunicationsoperator’s network operational efficiency, optimize network structure purposes.The topic for the Tieling Tietong MAN construction situation, and the idea of flatteningthe network, in-depth analysis of Tieling Tietong MAN core network structuretransformation of the former status quo, business development needs MAN, MAN problemsin the current network determined on the basis of this flattening transformation MAN TielingTietong principles and purposes, and Tieling Tietong MAN flattening transformation of theoverall planning ideas. Tieling also completed the transformation program Tieling Tietongflat MAN, MAN detailed on the core layer, convergence layer and access layertransformation are discussed. Meanwhile MAN existing VLAN ID for limited problem,VLAN classification, IP address carried out a detailed plan, as well as ensure thetransformation MAN service quality, especially for the quality of service (QoS) assurancemeasures in detail expositions and business is divided into six levels, to ensure that users ofthe service quality of all kinds of requirements.In order to protect MAN flat smooth implementation of the program to develop aflattening transformation Tieling Tietong MAN embodiment, this embodiment on short-term,medium-term and long-term planning of the combination of step by step implementation ofthe smooth evolution to ensure Tieling Tietong investment returns. This program is dividedinto four stages of renovation work on the implementation of the first three stages of thehierarchical structure based primarily on the metro, on the metro core layer, convergencelayer and access layer, layer by layer transformation, mainly to complete the fourth stageMAN data configuration and optimization, to achieve business support. The program notonly for the implementation of the program was discussed in detail, and the expected effectof the implementation of the program was evaluated, so better highlight the program isreasonable.The CRC developed Tieling MAN flat renovation program has easy to maintain, easymanagement, high reliability, flexible scalability, high security features. Tieling Tietongupgrading MAN provides a reference to the idea from the implementation of the program isbound to be able to Tietong MAN network architecture, network performance, network capacity increased to a new high ground, to enhance the Tieling Tietong the corecompetitiveness of the telecommunications market.Tieling developed this flattening transformation scheme of CRC have a maintainable,manageable, high ductility, high reliability, flexible security features. Tieling Tietongmetropolitan area network provides for reference of the thinking of upgrading,implementation of this programmed will be able to structure of the railway network of CRC,network performance, network capacity to a new vantage point, lifting Tieling Tietong corecompetition in telecommunications markets.
