Based On The Hierarchical Education Network Design And Implementation

Today with the rapid development of network and communication technology.The style and content of the people's learning also considerably varied. Now realize using computer to tackle with information is an urgent business. Going along the information searching and collection designing a convenient WAN has great importance. Following are the topic, discussing in this essay.1 The choice of the network topologic design. There has a lot limit with the plain topologic design in extensive, monitoring and management, so it's only adaptive to small local network design. The topic of this essay is about WAN, so we choice the layer structure design. There are three layers: center layer, assemble layer and accessing layer. The function of the center layer is mainly to realize the transportation between the backbone network, so when we design this layer, we should put our eyes on the rebound dependence and high speed transportation. The main function of the assemble layer is to connect the center layer and accessing layer. To the equipment of the assemble layer must burden all of the throughout of the center layer and accessing layer. The equipment of the accessing layer is advised to use common equipment, so this can make our system have the character of plug in plug out, this can make the system much more to maintenance and extend. When we design the accessing layer, the most important problem is extensive. This is a module design, so it can complete the network extensive, management and problem detection. Moreover it can produce good economic profit. In a word, it a advanced network design.2 Today, more and more computer and network have connection with the Internet, which can get the convenient to serf on line, but also bring in more and more unsafe problem. This essay bring out some opinion about the network security design, and also choice some to complete the network design. The most important security system we use in our system is intelligence IPS system based on the data mergence, which not only can detective the network attack, but can actively hold back the network attack., because of having used the data mergence and intelligence technology, it can detective the whole network activity on the same time, then use the intelligence technology to get the more acute result, so which can greatly guard the...
