The campus network is a broadband multimedia network that provides teaching, scientific research and comprehensive information services for teachers and students of the school. The campus network should provide an advanced information-based teaching environment for school teaching and scientific research. The campus network is required to be a broadband, interactive LAN and highly professional LAN. Multimedia teaching software development platforms, multimedia presentation classrooms, teacher lesson preparation systems, electronic reading rooms, and teaching and examination databases can all be run on this network. If a school includes multiple professional disciplines, multiple local area networks can also be formed and connected by wired or wireless means. The campus network should also have educational, administrative and general management functions.
The campus network is within the scope of the school and provides resources for school teaching, scientific research and management under certain educational ideas and theoretical guidance. In China, the construction of campus networks has developed rapidly in recent years. So far, nearly 6,000 schools in China ’s primary and secondary schools have built campus networks. They provide a good example for the realization of educational resource sharing, information exchange and collaborative work within Chinese primary and secondary schools. However, with the rapid increase in the number of campus networks across China, the requirements for how to achieve educational resource sharing, information exchange, and collaborative work among campus networks are becoming stronger.
Project Background
A middle school has multiple school districts, a large library, four key open laboratories under the Ministry, multiple multimedia classrooms and voice classrooms. The original network system was limited to colleges and universities, and could not form centralized management and sharing of various resources. These situations seriously hindered the school's network requirements.
Due to the ever-changing network technology, higher bandwidth and more advanced applications, this campus network will be able to achieve the advanced nature of application requirements in the next few years of operation, and can reach the advanced level of the industry in a longer period of time to protect users investment. At this stage, it can realize data, voice, multimedia communication, OA, MAIL, WEB services. The campus network to be built will be highly reliable, with 24 hours of uninterrupted, trouble-free, and stable operation. Local network problems cannot affect the operation of large networks.
