In recent years the famous Much agricultural engineering, Appliances to the countryside, the two network-based policy of universal education, the introduction of the original is so popular on campus networks have become unusually hot. Universities, high schools and even junior high, have assumed that their own campus network. The design is tailored for second high shcool of LiaoYang the campus network design, including the technical thinking of the various local area network, network design, network topology, cabling systems, Intranet / Internet applications, network security, network maintenance, etc. Design based on safe, efficient, has a certain redundancy and scalability of the principle of second high shcool of LiaoYang campus network design. In the choice of network technology, the choice of Ethernet networking technology as a technology campus network to fully meet the needs of the teaching office, is also in line with the current development trend of the latest technology. Second High School in Liaoyang net aggregate demand, together with consideration of applications to the construction of a high-performance, high reliability, high stability, high security, operations, can management, value-added Teaching Network office.
