The Network Design And Implementation Of Upgrading Of Hanxing Metallurgical Mine Administration

With the rapid improvements of computer and communication technologies,the applications of computer networks have an unprecedented development.The computer networks have become a necessary part and play a key role of people's daily lives, especially in the enterprises' maintenances.Only a solid infrastructure of computer networks can be trusted to support the rapid development of information,to encourage the reform of enterprises,also to enhance the core competitiveness of enterprises.Making an examples with the network upgrade of the Minmetals Hanxing Metallurgical Mine Administration(hereinafter refers as Hanxing Mine Admin),this dissertation discusses the related problems in the process of network upgrade and the pragmatic solutions according to the actual situations.The information construction of Hanxing Mine Admin started in the year of 2002. In 2005,Hanxing Mine Admin completed the intranet construction with the co-existence of the ADSL broadband line and the data line(mainly ADSL broadband line) and formed the SDH data line and the IPSec VPN networks of Hanxing Mine Admin.However,due to the instability of the ADSL broadband,the outmoded and low configuration of the network devices,unreasonable frameworks of the network and the shortage of effective method of maintenance and management,the network could not meet the requirements of the enterprise multinational and information development. Also it could not fit the requirements of the information strategies and plannings of Minmetals headquarters and the requirement of Project V5 promotion.In 2007,with the help of the Information Administration Division of Minmetals Corporation,Hanxing Mine Admin upgraded the corporate network.After the network upgrade,the computer network system of Hanxing Mine Admin becomes more safe, stable,highly efficient and expandable.It can meet the requirement of corporate information development,the promotion of the use of Project V5 in Hanxing Mine Admin.Just after the completion and stabilization running of the network system, Hanxing Mine Admin installed the HR module of SAP ERP system.In 2008,we managed the AutoCAD software implementation of genuine inside Hanxing Mine Admin with a small scale if online versions by the new intranet.And we succeeded the medical insurance system networking project inside the whole company. The aboved metioned two managed to save nearly 3 million RMB for Hanxing Mine Admin.In the future,based on the upgraded computer network system,Hanxing Mine Admin will focus on the promotion and construction of application system around the management and production operations of its own to improve the corporate core competitiveness...
