Campus Network Design and Simulation (Rawar Activity -3)

Goal

 On Friday 13th of Janruary, we were assigned a task to simulate campus network where our main goal was to allow guests to connect to campus network to access wifi seamlessly without exposing the campus's core infrastructure or other sensetive parts of network 

Planning and Data Collection

For this we created a simple plan that first we need to understand the already existing campus network, create a dummy infra on cisco packet tracer and get the basic model working , we divided out team into two sub-team one was tasked for data collection while other was tasked to learn and get comfartable with cisco packet tracer 

Our first sub team tasked with data collection went to all the college department collecting data of number of router , access point , network cabinets , speed of internet after joting this down they went to the lab attendents to ask question and understand the inner workings of the network. After visitng each department the team visted the guest house to understand how does guest actually connects to the network. After spending 2 days on data collection our first team has colected enough data to create a campus network

Network Creation and Simulation

After the first team collected all the data required, the second sub team started to plan there approach and it was finallized that the network infrastructure should use a Hardware Firewall, Vlans, DHCP to make the campus network secure and easy to scale. As per the documantation of first sub team it was decied that 4 VLANs should be made each named LABS, FACULTY, GUEST, INFRA , each of these seprating the network into virtual network with GUEST vlan having access to internet only , this design allowed easier isolation of network based on domain and also allowed for easier scaling  

Conclusion

The final network simulation successfully achieved the primary objective of allowing guests to access the campus WiFi without compromising the security and integrity of the campus network. By implementing VLAN (LABS, FACULTY, GUEST, INFRA), DHCP  and a hardware firewall, we ensured proper isolation between different departments and controlled internet access for guest users.

The use of VLANs improved network organization, enhanced security, and made the infrastructure easier to scale in the future. The GUEST VLAN was restricted to internet-only access, preventing any connection with sensitive internal resources.

Overall, the project demonstrated how proper network planning, segmentation, and security policies can create a safe and efficient campus network environment.
