Abstract


The information society, the government information technology is an important feature of modern government, a new model for the development of e-government, it is compatible with the information age government management. How to build use of advanced information technology and e-government, information technology, electronic means to raise the government's administrative efficiency and the accuracy of the level of administration and decision-making, resulting in more efficient, more scientific society, enterprises and public services, has become one of the more urgent work of governments at all levels. Improve the quality and efficiency of the work, to accelerate the transformation of government functions, the ability to enhance the emergency treatment of the government sector at all levels, and the ability of management decision-making ability as well as the ability of public services, promote social supervision, to achieve the development of information technology to stimulate industrialization strategy, the construction of e-government has a very important significance. This thesis is based on the actual situation in the Wuhou District, Chengdu, IP OVER SDH technology to build Wuhou electronic Zhengwuzhuanwang private network is divided into hierarchical design the core layer, convergence layer and access layer, combined Chengdu Railcom MAN status of the design and construction. The Wuhou the electronic Zhengwuzhuanwang engineering organizational implementation based on the results of this paper, the construction of the project. First, based on the SDH digital signal transmission characteristics and SDH optical network can achieve the transmission characteristics of multi-service analysis of IP OVER SDH technology and MAN. After the study found, and all kinds of private network construction in China's telecommunications network has become a mainstream technology, IP OVER SDH technology has broad application prospects quite good Ethernet compatibility, while the the Wuhou electronic Zhengwuzhuanwang The project is a case study in this technology. Second, the actual needs of the office of e-government to analyze, design and develop a electronic Zhengwuzhuanwang equivalent model. And combined with the actual situation, and develop a government Intranet and extranet design. Foundation and the basis of the entire e-government construction is the establishment of an equivalent model, so more conducive to the understanding of complex government management and running on the way, and thus provide a reference for the design and development of the construction program, and for the smooth transformation to e-government ideas. Third, based on the actual situation of the cable laying, and in close connection with the actual ground conditions geomorphology of the city, as a basis for the development of fiber optic cable path. Because the Wuhou electronic Zhengwuzhuanwang covering a larger area, it needs to Chengdu the Railcom MAN in each room and the cable distribution of resources to carry out a detailed analysis, thus as a dedicated network cabling design reference and basis for, and fully With Chengdu Railcom MAN advantages in resources, scientific and reasonable construction of the building. Fourth, from the perspective of the day-to-day maintenance, the types of faults in the network run statistics on a regular basis, and enumerate the actual maintenance work. To take through failure analysis and direction for future private network running smoothly and optimization.
