Network cable connection between buildings;

Trunk three-layer switch-a separate single switch for each building (the switch is divided into several network segments as required)-switches leading to each function room-each terminal.

As for resources, we should take out several servers to store e-books, video resources, office systems, student information, FTP on campus, website systems and so on.

The backbone network should apply for at least 1 G bandwidth from the network provider (telecom or Unicom) and fix the IP address.

The main router configuration must be high, preferably with port locking (FTP, WEB needs 1394 port) and data flow control network speed.
