Optimization Design Based On The SDH Network Performance

With the rapid development of the telecommunications industry, moderncommunication system have the main characteristics of large capacity, digital and distance,source and reliability, security, etc. Network scale is expanded rapidly, optical fibercommunication has the advantages of large capacity, domestic network often contains fromearly PDH technology to mature SDH technology until now the most advancedWDM/DWDM and other new technology, with the data service and telecom business ofbooming development, formed many manufacturers and transmission system coexist complexsituation. Also not afraid of electromagnetic interference, how to maximize, the mostcomprehensive make full use of this new type of transmission network resources, allcommunications company network bandwidth resources especially local backbone networkbandwidth resources nervous. Play to maximize its biggest function, thus the operationmanagement cost reduction, let the service quality and service quality have been improvedsignificantly, this has become the network construction emphatically the factors considered.So, optimization of the transmission network is getting more and more important.Based on the analysis of the existing transmission network technology, performance isbeing perfected, as well as to Z to communication company existing local backbonetransmission network structure research, improve the network resource utilization. Find theproblems existing in the network, all countries in the world have been widely used in opticalfiber communication, and find out the influence of network quality reason, as NGN and otheremerging business of the commercial and gradually popularization, expounds the companylocal backbone for the necessity of network optimization, The Atlantic, the Pacific Oceanbottom cable has been opened to use, particularly in SDH respectively and the networkconstruction scheme for the DWDM technology are analyzed． Optimization of localcommunication company currently use or have local SDH transmission network. In thecompany existing SDH optical transmission network, based on the acquisition data base, andcarries on the evaluation and analysis. This paper also will be through the network status andbusiness model in-depth discussion and analysis, analysis from several aspects, such asnetwork security, maintenance trouble analysis and so on, based on comprehensive analysis toput forward a optimization countermeasures to the complete solution, in test can be afterimplementation and overall implementation. The main purpose of this paper is through theoptimization of the network performance and resource, in order to improve cyber sourceutilization and safety to do some analysis and discussion, and provide some reference for themaintenance efficiency of cyber source system.
