Small Campus Network with Layer 2 Network Architecture



QSFPTEK tailors Layer 2 architecture networking for elementary schools campus network upgrade, using a direct connection from the access layer to the core layer. It creates a high bandwidth, stable network, and wireless integration intelligent campus network.



Due to the proliferation of digital education devices such as IP phones and cameras, and the requirement for wireless networks, the school's original 100M bandwidth needed to be increased for the demands of intelligent education. We need to build a full-coverage wireless access network and connect various terminal devices on campus.



For this small campus network, QSFPTEK technicians designed a two-tier architecture network by deploying S5300 and S7300 series switches, using the stacking function, LACP function, and PoE switches with AP+AC to achieve link bandwidth enhancement and full wireless network coverage.



In a small campus network, a two-layer network architecture is implemented, whereby the access layer is directly connected to the core. The adoption of a stacking + link aggregation network configuration ensures a ring-free network that is easily configurable and does not require the use of complex ring network protocols and reliability protocols (e.g., RSTP, MSTP, RRPP).


The core device employs S7300-48X2Q4C switches for stacking, which guarantee device redundancy. The access switches, on the other hand, use the S5300 series and are linked to the core switch via link aggregation. This arrangement enables the multiplication of the link bandwidth of the uplink device at the access layer and link redundancy backup, thereby significantly enhancing network stability.


The S5300 series supports POE+ power supply and, when used with AP+AC, facilitates wireless networking and eliminates the need for network cables to connect terminals. This, in turn, allows users to surf the internet while on the move, while also providing more flexibility in the deployment of wireless networks.


By ensuring network device-level and link-level reliability, this networking solution simplifies the network topology and reduces the workload associated with deployment and maintenance.

Customer Benefits


The quality in teaching and learning has been significantly enhanced with the implementation of a highly efficient wireless network. The access switches, with their ability to support full-port wire-speed forwarding, have been instrumental in optimizing a seamless digital experience for both teachers and students. Furthermore, the deployment of ultra-fast Wi-Fi coverage in various locations such as learning and teaching buildings, the library, and the dormitory has met the diverse wireless access needs of the entire academic community.


To ensure the security of information belonging to teachers and students, potential network risks have been minimized. This has been achieved through the use of isolated wireless guests via wireless network SSID and VLAN binding. Additionally, quick allocation of network access permission has been enabled for teachers, students, and visitors, thereby preventing malware from infiltrating the network while simultaneously safeguarding important and sensitive information.
