Abstract

With the gradual popularization of networks, office networks are all business units, institutions, government agencies to the development of information inevitable choice. The Graduation Project Shijingshan Health Bureau LAN systems are a very large and complex system, which not only comprehensive information management and office automation applications, such as a series of basic operating platform, but also provides a wide range of applications, so that information can be timely and accurate to send to each system. The Shijingshan Health Bureau LAN construction of the main applications of network technology to the important branch of local area network technology to the construction and management, So this graduation project topics will be mainly to Shijingshan Health Bureau LAN construction process may use a variety of technical and implementation options for the design direction for the Shijingshan Health Bureau building LAN and provide a theoretical basis and practical guidance.

Keywords: LAN, Internet, computer networks, network protocols, server, firewall。
