  • Networking cisco and report

    Hey, this is my NET-351 project (airport network system). I uploaded everything:

    • Final report (Word)
    • Project proposal (PDF)
    • Project sheet (requirements/rubric)
    • Problem scenarios file
    • Presentation template (PPT)

    The idea I chose is the airport network (Scenario 4 resilient airport network).

    I need you to:

    1. Improve and polish the report so it matches the required structure:
      • Problem Identification
      • Business Objectives
      • Requirements
      • Network Design
      • Simulation & Testing
      • Conclusion
    2. Make sure everything fully matches the project sheet requirements.
    3. Create a professional presentation (10 min) using the template.
    4. MOST IMPORTANT: Build a Cisco Packet Tracer network based on the airport design:
      • Core, Distribution, Access layers
      • VLANs (FIDS, Security, Staff, WiFi, etc.)
      • Routing (HSRP / OSPF or EIGRP)
      • Redundancy (failover test)
      • Run ping tests and screenshots

    Everything is already written, just needs to be upgraded to A-level quality and implemented properly.

    Let me know if anything is missing

    • Define the test scenarios:
      • Both protocols are tested separately but under identical conditions
      • Same payload size, same interval, same duration, same machine
    • Preprocessing:
      • No preprocessing needed data is generated and sent directly
