Municipal Tunnel SOC Layer-3 Backbone
Municipal tunnel SOCs use L3 cores to aggregate multiple galleries/districts with inter-tunnel routing.
1. Scenario
Cities build multi-phase tunnels; the SOC must onboard them, delegate ops, and peer with lifeline platforms.
2. Challenges
Address/VLAN clashes; video vs analytics peering; compliance zones.
3. Architecture
PH-4M32P-M L3 core; district 24GE aggregation; gallery rings into districts; 10G to storage/platform zones.
4. Recommended Leagrid LGS2000 products
- LGS2000-PH-4M32P-M: Layer-3 industrial core: 4×10G + 8 Combo + 8 GE fiber + 16 GE copper, 19″ 1U—campus/backbone routing.
- LGS2000-24GE4GF-M: Managed rack aggregation: 24×GE copper + 4×GE SFP for station/central-room aggregation.
- LGS2000-8GE4GF-M: Managed Gigabit switch: 8×GE copper + 4×GE SFP for multi-direction fiber rings and multi-camera uplinks.
5. Deployment notes
Route/ACL per gallery/district; isolate platform zone; bastion + centralized logs; reserve ports for Phase-2 galleries.
