How to implement a smart campus project? The main challenge lies in the networking. In this issue, we will understand campus networking through three diagrams.
Three diagrams, detailing campus network networking
1. Main components of the campus network framework
The campus network mainly consists of several parts: data center, wired network, wireless network, IoT, smart classrooms, and core exit.In fact, it is also composed of three parts: internal network, external network, and device network.External network:Exit router/firewallInternal network: wired network, wireless network, office network, etc.Device network: IoT, etc.2.

The above shows the implementation methods of various networks and core devices. The general framework is also a three-layer structure, which is not much different from ordinary networks, but the devices at the access and core ends are more complex.3. Overall campus networking diagram
Network security protection is an important part of the campus network. Data security is extremely important, with multi-layerprotection, each layer has its own purpose.
Exit firewall:
Deployed at the network exit, it allows or denies data packets based on preset security policies (such as IP address, port, protocol), preventing external attacks and unauthorized access.
Intrusion Prevention System:
Real-time detection of network traffic, it can not only detect attacks (such as exploits, DDoS attacks, malware propagation) but also actively intercept and block these attack behaviors.
Web Application Firewall:
Specifically protects the school’s external websites and applications (such as the official website, enrollment system, academic affairs system), defending against SQL injection, cross-site scripting, and other attacks targeting the web layer.
