Design And Practice Of Ganzhou Unicom Local Transmission Network Optimization

The competition in the telecommunication market has become more and more fierce, which cause a result that the service provider pay more attention to the quality and the security of the network. The transmission network is the foundation of the whole communication network, but due to the mass construction earlier, the shortcomings are getting more and clearer, and the network optimization is the only way to solve the problem.This article analyzed the originally existed data transmission network in Ganzhou Unicom. The network structure, operation, and network problems are analyzed theoretically and technically.Based on the Synchronous Digital Hierarchy (SDH) and Dense Wavelength Division Multiplexing (DWDM) technology, this article proposed an improvement strategy and plan.Currently, SDH and DWDM are widely used optical transmission technology.They have been used in many type of communications networks. This article summarized the current applications and developments of the optical transmission networks and also the characteristics and functions of SDH as well as DWDM.Combined with the Ganzhou Unicom data transmission network optimization project, we proposed a improved design for the transmission network in Ganzhou.The original data transmission network of Ganzhou Unicom had many flaws, such as low capacity, few types of services, unstable hardware and so on.Based on the analysis on the network structure, operation, and network problems of the original network,we studied the Ganzhou Unicorn’s transmission network optimization strategy and implementation plan. We proposed a new improved plan.In this paper, the major work done by the author is:From the capacity, security, business needs, network node, topology, and other aspects, analysis the transmission network status and development trends;On the basis of theoretical analysis, existing transmission network data acquisition, research and analysis the problems of the transmission network;In view of the analysis result, in accordance with the transmission network own characteristics and actual situation, design a variety of optimization programs;Using these optimization design program in Ganzhou Unicom local transmission network optimization work.Through transmission network optimization, transmission capacity, quality, reliability, resource utilization, and so have been substantially higher. Proved that the design optimization program is feasible and effective.
