(The purpose of the construction of the campus network of a certain technical school is to build a stable, safe and reliable campus network to provide an excellent network infrastructure platform for the college's informatization construction. The campus network is divided into three layers, and adopts the three-layer network architecture of core-convergence-access. The core layer is composed of two 10G core switches, which are interconnected through 10G fiber links to form 10G Ethernet to ensure the high performance and high stability of the backbone network. Aggregation switches that support 10 Gigabit expansion are used in the building, and are connected to the core equipment through Gigabit fibers. The regional access layer switches are connected to the building aggregation layer switches through gigabit twisted pair cables or gigabit optical fibers to realize the campus network topology of 10G backbone, gigabit aggregation, and 100M to the desktop.)
