Research On The Optimization Of SDH Optical Transmission Network In Binzhou Unicom

Now the world has already entered the information age.The need for higher efficient production and activity makes people place more and more importance on time, and also urges the SDH optical transmission system to develop to a higher level both technically and theoretically.Nowadays,SDH optical transmission system has already become a modern communications network widespread use of the base transmission network system.As a basis for supporting the optical transmission network,after the phase of the project's construction,the optical transmission network has formed the basis of platform. However,due to tight time limit,the investment is limited to the construction of transmission network for mobile communications in the position of supporting services, transmission and network construction at the opening of the primary objectives,lack of sustainable development as the goal of the overall plan.With the network G,C and data scalability,capacity tension and the other issues,have become increasingly prominent. Transmission network optimization technology is not only the result of the development, but also the actual demand of various network operators in the operation and maintenance,because the merits of the quality of transmission network has also decided to a large extent,the competition among the operators of the results.So the network optimization work is imperative.Based on the reasons referenced above,firstly I made a brief introduction to the characteristics of SDH optical transmission system in my dissertation,mainly about the performances and the key technologies in SDH optical transmission system optimizing, and then combined with the actual network in Binzhou,such as SDH optical transmission network of China Unicom in Binzhou existing for data collection and analysis of assessment,through in-depth analysis of network status and business model, bearing type of business and traffic patterns and bandwidth allocation,utilization of network resources,network security,fiber channel resources and risk maintaining fault analysis,and so on,to optimize the rectification and reform program and implementation.The following objectives are predicated to achieve:improving network resource utilization,carrying more rich for the business;improving network security; maintaining system efficiency;lowering maintenance costs;obtaining the more convenient management and improvement.
