Research On Access Network's Layout And Optimization Method And Its Application

With several years' development, the technology of access network has been improved greatly. In general, DSL is still the first choice for companies of Broad Band in the world, and the wireless access network has become the essential technology to the establishment of the network. As the investment of access network increasing , new and higher requirements for the layout, optimization and engineer design has been put out.Firstly, this paper introduces the researching background and current situation of access network layout, and gives the summary of the key technology. Secondly, this paper gives a new model of analyzing the telecommunication companies in certain areas . This analyzing model has been applied practically; the model has great referencing significance to the analysis of network layout environment in different areas of our country. Thirdly, this paper also gives the analyzing-evaluating system of the access network's value engineer. Some contradict problems between technology, economy and demand existed in the layout of network has been solved comparatively perfectly. Finally, this paper gives some new idea in the access network traffic prediction. According to a certain city's access network's construction status and traffic requirement, four possible access network backup layouts have been given .In the paper, more research has been made on the problems existed in the practical project application of environment analyzing and value engineering, and the further research aspect has been brought forward.
