Research Of Network Optimizational Scheme Of Backbone Transmission Network By Henan Unicom

With the telecommunications industry resforming and 3G licences issued in 2008, the domestic telecommunication business direction of development is changing from vioce-oriented to data-oriented. Exchange technology is also accordingly changed from traditional circuit switching technology step by step to data exchange and broadband exchange of group domain, so as to adapt to the next generation network based on IP comprehensive features of the soft exchange business development. Henan unicom's transmission backbone carrying each company business, at the same time, is also evolving to the direction of optical networks, IP melt, intelligentification.Firstly,It reviewed the development of optical transmission network and deeply researched each transmission technology of henan unicom diaphysis transmission network in this paper. Secondly,It expounded three-level reflect of henan unicom transmission lines and introduced the network structure and the present situation of the main transmission network.Through the investigation and research, it analyzed henan unicom main transmission business requirements in 2010. Then, through integratining the resources of the two networks and optimizing network configuration.We have formulated optimizational scheme of henan unicom transmission network. It includes former netcom e-government private network optimization expansion 40 x huawei Gb/s 2.5 40 x d system, huawei lOGb/s wavelength systems; The original unicom zte 40 x 2.5 G/10Gb/s wavelength system, optimize the expansion of the original netcom huawei SDH transmission MESH, and in the original unicom zte wavelength platform 10Gb/s new SDH network. In the end of the paper,through summing up the work, we have a prospecting for the next step in network optimization.Through this network optimization plan implementation of trunk transit network in henan, promoted two nets fusion, and greatly improved each office points' network security and tolerant ability, and also boosted long-distance transmission network gradually turning to high capacity, intelligence, multi- business bearing, and operational intelligent optical networks in henan province. Also provided a powerful guarantee for the informationation development and launching abundant information application in all social circles.
