With the rapid development of computer and network technologies in China, the information management level of enterprises and government is improving continuously; more and more government organizations have their own e-government systems based on the Internet. As the foundation of the Internet, WAN has got a big leap in recent years, as what can be seen, numerous information projects are under construction from the central authorities down to local authorities. This article gives a construction plan on WAN based on Golden-Finance Project.In this paper, I analyzed the demand fist, drawing up the goals and construction scales, then gave an overall design on this WAN. In the next, I proposed a network security plan, specifying the routing scheme and IP address allocating plan. At last, I offered a QoS solution which ensures good transfer quality and stabilization of network.This plan is based on the actual networking development level in China, having strong operability and advisability, it is a valuable reference for the system construction and optimization. |
