The Application Of The Modern Network Communications Technology In The Info Intelligence Community

The model based on intranet of the network system of informative intellectual community is established and the overall project of the system is presented in the paper, involving the specific application of multiple network technologies and the brand-new thought applied in the future community's network technologies.. Basic theoretical analysis are done for many network technologies, such as QOS, COS, difference service , layers commutation, VLAN and high-speed respite store technologies, and so on . The practical target of application, pattern and position of these technologies are illustrated in the paper .The basic characteristic parameters of various network equipments applied in the system practically are then introduced. Finally, it stresses on the most principal problem after the network has constructed and begins to run-the security of the network., the designing method of network security and the services and the protection mechanism with relation to the network security are advanced .It is a emphasis the analysis of lire prevention wall technology of the network security and the practical application of this technology in the system .
