The Design Of Ethern Network Of Enterprise And Research Of Enterprise Information Network

With the continuous development and popularization of computer, more and more information are needed for the people, Single computer can no longer meet the information needs of the people, It is this need to promote network technology has been rapid development. And just it's this that makes it become the important carrier and platform that can help people to send information, transmitted information, and use of information. And it's play integral role in the people's learning and working life. And become more important tool to enterprise for improve efficient and effective.Ethernet technology as a mature computer network technology has been widely applied to all size of local network. IEEE (Institute of Electrical and Electronics Engineers, Institute of Electrical and Electronics Engineers) has developed a standard named IEEE802.3 and gives Ethernet specification. Because of the characteristics of Ethernet that at the greatest degree of minimize the conflict, increase network speed and efficiency, using Switch and Router to link and organizational. Largely replaced the other LAN type, as the most popular LAN technology.This paper analysis of principles of Ethernet LAN and construction of architecture by the actual construction of sihua company's network. Detailed studied of the network topology, IP address design, and actual configuration of routers and switches set up a deployment flexibility, high bandwidth, scalability and strong practical Ethernet LAN.
