Hughes IT Consulting — 3D stack

Network infrastructure model

Configure routers, switches, VPNs, servers, and desktops across multiple sites. Trace shortest-path hops between any two devices, run real traceroutes to discover actual network paths, and explore the scene built on the same React Three Fiber approach as the HITC NetworkTopology component.

Topology

Sites, devices, and links. Shapes follow role (from the HITC 3D component pattern).

Sites

  • HQ — Core
  • Branch — East

Devices

  • Internet / Cloud (cloud) — HQ — Core
  • Edge firewall (firewall) — HQ — Core
  • Core router (router) — HQ — Core
  • Access switch (switch) — HQ — Core
  • App server (server) — HQ — Core
  • VPN headend (vpn) — HQ — Core
  • Branch router (router) — Branch — East
  • VPN endpoint (vpn) — Branch — East
  • Floor switch (switch) — Branch — East
  • Desktop A (desktop) — Branch — East
  • Desktop B (desktop) — Branch — East

Links

  • Internet / Cloud ↔ Edge firewall (ethernet)
  • Edge firewall ↔ Core router (ethernet)
  • Core router ↔ Access switch (ethernet)
  • Core router ↔ App server (ethernet)
  • Core router ↔ VPN headend (ethernet)
  • VPN headend ↔ VPN endpoint (vpn_tunnel)
  • VPN endpoint ↔ Branch router (ethernet)
  • Branch router ↔ Floor switch (ethernet)
  • Floor switch ↔ Desktop A (ethernet)
  • Floor switch ↔ Desktop B (ethernet)

Data path

Pick two endpoints to see the modeled path, or run a real traceroute to discover the actual network hops and compare them.

Choose both endpoints to trace a path.

Discovery

ARP reads the host's cache only. Nmap runs on the server with a validated target (IPv4, CIDR, or last-octet range). Install Nmap and Npcap on Windows; only scan networks you own or are authorized to test.

Nmap (server)

Default CIDR allowed: /24–/32 (set NMAP_MIN_CIDR_PREFIX / NMAP_MAX_HOSTS). NMAP_PATH, NMAP_TIMEOUT_MS, NMAP_EXTRA_ARGS (e.g. --unprivileged), disable with NMAP_SCAN_ENABLED=false.
