This project demonstrates how enterprise networking concepts like VLANs, OSPF routing, ACLs, DHCP, NAT, and IoT automation come together to form a modern digital airport infrastructure.

🔧 What I Built

I designed a full multi-department airport network with:

• 4 VLANs (Authority – 10, Security – 20, Flight Services – 30, Guest – 40)

• Layer-3 Core Switch Routing using OSPF (Area 0)

• DHCP servers in each zone for dynamic IP assignment

• ACL rules to restrict Guest access

• Internal Web Portal hosted in Flight Services

• RFID-based IoT Access Control System under Security VLAN

• NAT for future external internet access (optional)

Each department operates in its own logically isolated network but communicates through dynamic routing.

🧩 Tech Stack & Protocols

• Cisco Packet Tracer

• VLANs

• OSPF Dynamic Routing

• ACL (Access Control List)

• DHCP

• NAT

• IoT Devices (RFID Reader + Card + IoT Server)

• Layer-3 Switching

• Internal HTTP Web Servers

🚀 Key Highlights

🔹 1. VLAN-Based Segmentation

Each airport section gets its own network to ensure security and reduce broadcast traffic.

🔹 2. OSPF Dynamic Routing

OSPF automatically learns and updates routes between all VLANs — perfect for large networks.

🔹 3. ACL for Guest Security

The Guest zone (VLAN 40) is fully isolated from sensitive zones, except for controlled access to the flight-info web server.

🔹 4. IoT RFID Access Control

I integrated an RFID Reader + Server setup, simulating employee access validation inside the Security zone.

🔹 5. Internal Airport Web Portal

The Flight Services server hosts a simple airport page accessible across the network.

🏁 Conclusion

This project helped me explore how networking + IoT can work together inside a real-world environment like an airport. From VLAN segmentation to routing and automation, it covers the core principles used in modern enterprise networks.

If you’re learning Computer Networks, this project is a great way to understand how multiple protocols interact in a practical scenario.
