The enterprise campus network design and implementation
Abstract: With the rapid development of computer network technology, especially the application of the Internet is becoming more and more widely, in has brought the unprecedented huge amounts of information at the same time, the network of openness and freedom also had private information and data are destroyed or infringe upon the possibility of network information security is becoming increasingly important, has been paid great attention in the areas of information society. In the network era of rapid development, the network to the development of enterprises has become the essential. There are something been discussed briefly in the enterprise network designing, relating to the network technology, the way of designing procedures, the network function and applying analysis and so on, is that the network plan of enterprise, which provide a reference on the technology and application , to make it have higher function in building or planning campus network. Through to analyzing to the network, in order to satisfy the requirement of the area network from the value and performance, then carriry on to configure the enterprise area network including piding VLAN, establishing management territory and so on, optimizing the enterprise the network unceasingly, thus make the enterprise access network resources speedily and safely.
