The Design And Implementation Of Network Reform Of The Power Company Branch

This project comes from a construction project of LAN core transformation and metropolitan area network of a power branch company. The network structure must be planned again, along with the increase of the business application system on network and the launch of the new technology. How to design the network has become the focused problem of the power company.There are three large businesses for traditional metropolitan area network:user access supply, business transmit and content services. With the progress of the society, people’s demands have greatly improved. The basic businesses that provided by the traditional metropolitan area network cannot meet the demand of market, along with the increase in ISP. So, in the process of network design, adjust must be done according to the needs of users. Ensure that the existing advanced technology combined with the standards. Modular and extensible multilevel network architecture will be adopted to solve the challenges of LAN design.This program will be transformation of the core layer,convergence layer,access layer and data center.The overall requirements of network performance is achieved by:one core routing switch, one aggregation switch,9 institutions access switches with NE05 dilatation, 33 standing side access switches,1 set of network management system. According to the design of network management software, we conducted principle analysis by six aspects: from the development environment, running environment, system structure design, data acquisition, fault management to data processing. On the basis of the principles understanding, this paper realized the centralized monitoring and management to the network, using the designed network system. A set of user security authentication scheme was designed to provide network services to legitimate users. At the same time, the design scheme of the network management software is gradually improved.This project can meet all kinds of businesses that application system have, at the same time, it reflects the advanced nature of the network system.The network system will be a high stability and meet all kinds of new business needs.
