The solution of distributed three-layer switch Intelligent Campus Network

With the further development of modern teaching activities and the frequent interaction of teaching institutions at home and abroad, the demand of schools to communicate complex information through the network is more and more vigorous, and the campus network which is simply connected to the Peer-to-peer network has not satisfied the application demand of the school, and the intelligent network has become the developing direction of the Therefore, in order to keep abreast of the rapid development of educational informationization, the construction of Intelligent Campus Network has become an inevitable choice for modern educational institutions.

What is the Intelligent Campus Network

An intelligent campus network should have the following characteristics:

1, speed of the network connection

Campus Network is the core of the campus-oriented network for teachers and students, so the park LAN is the focus of the construction of the system, because of the number of teachers and students involved in network applications, and the information contains a large number of multimedia information, high-speed network connection has become an essential prerequisite for the formation of campus network.

2. Diversity of information structure

Campus network should meet the needs of different levels of application, can be divided into multimedia applications (Internet access, multi-media teaching, electronic library, video on demand, school sites, internal e-mail, etc.), information management (score statistics, file management, etc.) and remote communications (external dial-in, off-site interconnection, etc.) three major parts. Because of the complex data composition, different types of data have different quality requirements for network transmission.

3. Good extensibility

For schools, often replacing network equipment is a large amount of expenditure, in the process of building a campus network should first consider the factors in the next 5 years of sustainable expansion, the use of three-layer switch is in tune with the needs of today's school network and the future of the overall network improvement and upgrade.

4. Safe and reliable

The campus network has a large number of important data on teaching and file management, whether it is damaged, lost or stolen, will bring great losses. In the security aspect, the school uses the firewall function to divide the campus network into the inside and outside two parts, thus avoids the internal network core server to be violated; In view of the networking equipment more, the structure is more complex, using the same manufacturer's network management can carry on the more detailed administration to the equipment, enhances the network

5, easy to operate, easy to manage

Campus Network for teachers, students and office staff at different levels of knowledge, application and management should be simple, network management software should be all Chinese, user-friendly interface, easy to use, not too professional.

6. High cost performance

The school's investment in network construction is limited, so the network should be built to be economical and practical, the choice of switch equipment should first consider products cost-effective, after-sales service strong manufacturers, and according to the actual needs of their own network, tailored.
