Milestone Project — Ethernet Network Design Project

Designed a complete Ethernet network infrastructure for a four-level building, including structured cabling, switching architecture, and security implementation. This project simulated a real-world network deployment scenario, requiring both technical design decisions and cost-performance tradeoff analysis.

🔍 Project Highlights

  • Designed a hierarchical star topology with centralized equipment room and distributed telecommunications closets
  • Planned and calculated 148 network drops across a multi-floor environment
  • Implemented Cat6 structured cabling with distance constraints aligned to industry standards
  • Designed a fiber backbone (OM3 multimode) for scalability and high-speed interconnects
  • Selected and integrated managed PoE switches for network segmentation and device support
  • Configured a pfSense firewall (Netgate 6100) for network security, VLAN segmentation, and potential IDS/IPS
  • Integrated Wi-Fi 6 access points for modern wireless coverage
  • Developed a cost-optimized bill of materials (~$13,591) balancing performance and budget

🧠 Applied Networking & Security Concepts

  • Network topology design and hierarchical infrastructure
  • Structured cabling standards (Cat6, ANSI/TIA-568 alignment)
  • VLAN segmentation and network isolation
  • Firewall-based security architecture
  • Scalability planning using fiber backbone
  • Real-world budgeting and hardware selection
