Task details:
PSU has different branches all around Saudi Arabia, PSU is keen to expand more new branches in big cities:
New branch in Dammam (700 users)
New branch in Madinah (600 users)
New branch in Tabuk (500 users)
New branch in Al-Khobar (400 users)
You are required to design the topology for the four new sub-networks and their connection to the head office (Riyadh). You must document each step you have taken, including your research sources. You need to come up with a design report and send it to your technical manager.
Report: The report must contain the following sections
1. Introduction
2. Design of Network topology for PSU campuses
3. Floor-wise network design for each branch and their interconnectivity.
4. IP Addressing/ Subnetting
5. Required Software/Hardware
6. Conclusion
The PSU uses 180.XY.0.0/16 (Note: XY is the last 2 numbers in your student’s ID) at the campus in Riyadh with 1000 users and needs to use a subnetting structure to incorporate the new cities. Adhering to the subnetting scheme, assign a subnet address to the networks and their links. Each campus has 8 levels of building and access to the Internet is crucial for each office, as well as inter-branch-office networking. Each branch has 3 servers which are located on the Fifth floor of each branch. The main campus is in Riyadh and the new subnets must have connectivity with the main campus. You need to think about cost-effectiveness and PSU is aiming to create an Intranet for its branches in KSA. You need to think about creating a VPN for this campus
Students will choose a solution, and then implement and evaluate their solution. Students must submit a report that outlines the steps they followed to solve the problems. The approximate word length is up to 800 words with topology diagrams. The report should be presented with supporting material as appendices, such as the calculations for the IP addressing scheme
