Study On Enterprises LAN Construction Strategy

Nowadays, along with the rapid development of computer network, all kinds of network products emerge in endlessly, the frequency of products updates increasingly day by day, enterprises'dependence on network has transited to the needs of enterprise LAN construction strategies ,capability to provide high-efficiency, stable, and unblocked network environment, meeting all requirement of the enterprise daily work, from originally choice of network model equipment Therefore, due to the computerization of global information and the rapid development of the network, it is an urgent task for the enterprises to establish the internal LAN out of the developing tendency and the interests of the enterprises themselves. And how to build up a safe and efficient, reasonable and expandable LAN is a hot issue worthy of studying.The paper firstly introduces the current situation of the construction of the enterprise LAN, the key technology, and the developing trends of it. The second part focus on several strategies of the construction of enterprise LAN and designs a model of modern enterprise LAN strategy using "dual core" structure, which meets the demand of the enterprises of a high reliability, a high efficiency, and a expansibility of the LAN. This part puts forward different construction strategies of enterprise LAN according to the number of information points and the amount of investment capital, by studying several common construction strategies of enterprise LAN. The model is a scientific, effective and reasonable construction strategy for enterprises, which fits for their scale and meets their business needs of daily office LAN, and it is reliable.The paper analyzes relevant routers, switches and other network equipment of both the domestic and the international enterprise network, pointing out their advantages and weaknesses. As for high reliability, efficiency and expansibility, it adopts some key technologies such as VTP, STP and HSRP. Finally, it designs a new system of construction strategies. Meanwhile, it has carried on the detailed design and coding of the common strategies. It is obvious that the construction strategies suggested in this paper contribute a lot to enterprise LAN construction, which is helpful to increase the security, expansibility and efficiency of the office network, which meets the current demand of the enterprises of their internal LAN and which improves the working environment and increases the utilization of the computer equipment.
